what was the total amount of the checks listed on the opposite site of the deposit slip
The total amount of the checks listed on the opposite site of the deposit slip was $ 548.65. The correct option is (B).
What do you mean by deposit slip?When a bank customer deposits money into an account, they typically add a little paper form called a deposit slip.
The account may belong to the user personally or it may belong to another else. A deposit slip functions as a sort of insurance for the customer and the bank.
A deposit slip is a document that by definition includes the date, the depositor's name, account information, and the sums being deposited.
Here,
Calculation of total amount of the checks:
Total amount = 123.51 + 211.00 + 214.14
Total amount = 548.65

An isosceles triangle has an angle that measures 136°. What measures are possible for the other two angles? Choose all that apply.
Answer:
The other two angles are 22° , 22°
Step-by-step explanation:
To find the other angles, we can use angle sum property of triangle.
The given angle 136° cannot be base angles. Let the base angles be x.
x + x + 136 = 180°
2x + 136 = 180°
Subtract 136 from both sides,
2x = 180 - 136
2x = 44°
Divide both sides by 2,
x = 44 ÷ 2

High School Geometry
BC is tangent to circle A, and the value of r is 10.
Given,
BC=24
CD=16
AD=AB=r
To find the value of r, we can use the fact that a tangent line to a circle is perpendicular to the radius at the point of tangency. So we know that angle ABD is a right angle, and we can use the Pythagorean theorem
The Pythagorean theorem can be used to calculate the value of r:
\(AB^2+BC^2=AC^2\)
\(r^2+24^2=(r+16)^2\)
\(r^2= (r+16)^2-24^2\)
\(r^2\)= \(r^2\)+256+32r-576
\(r^2\)=\(r^2\)+32r-320
\(r^2-r^2\)-32r=-320
-32r=-320
r=320/32
r=10
Therefore the correct answer is r=10.

for what values of k can 2x^2 kx 5 be factored as the product of two linear factor with integer coefficents
The values of k for which 2x² + kx - 5 can be factored as the product of two linear factors with integer coefficients are k = 3, 1, and 9.
What is a linear factor?
A linear factor is a polynomial of degree one, which means it has one variable raised to the first power and a constant coefficient. In other words, it is an expression of the form ax + b, where a and b are constants and x is the variable.
We can factor the quadratic 2x² + kx - 5 into the product of two linear factors with integer coefficients if and only if its discriminant is a perfect square.
The discriminant of the quadratic equation ax² + bx + c = 0 is given by the expression b² - 4ac. In this case, a = 2, b = k, and c = -5. Therefore, the discriminant is:
b² - 4ac = k² - 4(2)(-5) = k² + 40
For the quadratic to be factored into two linear factors with integer coefficients, k² + 40 must be a perfect square.
One way to proceed is to list the perfect squares that are 40 greater than a square, and see if k is one of the corresponding values. We can do this by solving the equation:
k² + 40 = m²
where m is an integer. Rearranging, we get:
k² - m² = -40
This is a difference of squares, so we can factor it:
(k + m)(k - m) = -40
We now need to find integer values of k and m that satisfy this equation. We can do this by considering all possible pairs of factors of -40 and solving for k and m.
The pairs of factors of -40 are:
(-1, 40), (-2, 20), (-4, 10), (-5, 8)
For each pair, we can solve the system of equations:
k + m = a
k - m = b
where a and b are the two factors in the pair. Adding these equations, we get:
2k = a + b
Subtracting them, we get:
2m = a - b
Solving for k and m, we obtain:
k = (a + b)/2
m = (a - b)/2
We can now check if the values of k and m are integers and if they satisfy the original equation.
For example, if we take the pair (-1, 40), we get:
k + m = -1
k - m = 40
Adding these equations, we get:
2k = 39
This implies that k = 39/2, which is not an integer, so this pair does not work.
Trying the other pairs, we find that:
(-2, 20) gives k = 9 and m = 11, which works
(-4, 10) gives k = 3 and m = 7, which works
(-5, 8) gives k = 1 and m = 3, which works
Therefore, the values of k for which 2x² + kx - 5 can be factored as the product of two linear factors with integer coefficients are k = 3, 1, and 9.

1. Find the values of for which the gradient function of the curve = 23 + 32 −12 + 3 is zero.
Hence, find the equations of the tangents to the curve which are parallel to the −axis.
To find the values of x for which the gradient function of the curve is zero, we need to find the values of x that make the derivative of the curve equal to zero.
The given function is: \(\displaystyle\sf f(x)=23x^{3}+2x^{2}-12x+3\).
To find the derivative of the function, we differentiate each term with respect to x:
\(\displaystyle\sf f'(x)=69x^{2}+4x-12\).
Now we set the derivative equal to zero and solve for x:
\(\displaystyle\sf 69x^{2}+4x-12=0\).
We can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. Let's use the quadratic formula to find the values of x:
\(\displaystyle\sf x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}\).
Plugging in the values a=69, b=4, and c=-12, we get:
\(\displaystyle\sf x=\frac{-4\pm \sqrt{(4)^{2}-4(69)(-12)}}{2(69)}\).
Simplifying further, we have:
\(\displaystyle\sf x=\frac{-4\pm \sqrt{16+3312}}{138}\).
\(\displaystyle\sf x=\frac{-4\pm \sqrt{3328}}{138}\).
\(\displaystyle\sf x=\frac{-4\pm 8\sqrt{13}}{138}\).
Therefore, the values of x for which the gradient function of the curve is zero are given by \(\displaystyle\sf x=\frac{-4+8\sqrt{13}}{138}\) and \(\displaystyle\sf x=\frac{-4-8\sqrt{13}}{138}\).
To find the equations of the tangents to the curve that are parallel to the x-axis (horizontal tangents), we substitute these x-values into the original function \(\displaystyle\sf f(x)\). The resulting y-values will give the equations of the tangents.
For \(\displaystyle\sf x=\frac{-4+8\sqrt{13}}{138}\):
\(\displaystyle\sf y=f\left(\frac{-4+8\sqrt{13}}{138}\right)=23\left(\frac{-4+8\sqrt{13}}{138}\right)^{3}+2\left(\frac{-4+8\sqrt{13}}{138}\right)^{2}-12\left(\frac{-4+8\sqrt{13}}{138}\right)+3\).
For \(\displaystyle\sf x=\frac{-4-8\sqrt{13}}{138}\):
\(\displaystyle\sf y=f\left(\frac{-4-8\sqrt{13}}{138}\right)=23\left(\frac{-4-8\sqrt{13}}{138}\right)^{3}+2\left(\frac{-4-8\sqrt{13}}{138}\right)^{2}-12\left(\frac{-4-8\sqrt{13}}{138}\right)+3\).
These two equations represent the equations of the tangents to the curve that are parallel to the x-axis.

4tan(x)-7=0 for 0<=x<360
Answer:
x = 65.26 degrees or x = 245.26 degrees.
Step-by-step explanation:
To solve the equation 4tan(x)-7=0 for 0<=x<360, we can first isolate the tangent term by adding 7 to both sides:
4tan(x) = 7
Then, we can divide both sides by 4 to get:
tan(x) = 7/4
Now, we need to find the values of x that satisfy this equation. We can use the inverse tangent function (also known as arctan or tan^-1) to do this. Taking the inverse tangent of both sides, we get:
x = tan^-1(7/4)
Using a calculator or a table of trigonometric values, we can find the value of arctan(7/4) to be approximately 65.26 degrees (remember to use the appropriate units, either degrees or radians).
However, we need to be careful here, because the tangent function has a period of 180 degrees (or pi radians), which means that it repeats every 180 degrees. Therefore, there are actually two solutions to this equation in the given domain of 0<=x<360: one in the first quadrant (0 to 90 degrees) and one in the third quadrant (180 to 270 degrees).
To find the solution in the first quadrant, we can simply use the value we just calculated:
x = 65.26 degrees (rounded to two decimal places)
To find the solution in the third quadrant, we can add 180 degrees to the first quadrant solution:
x = 65.26 + 180 = 245.26 degrees (rounded to two decimal places)
So the solutions to the equation 4tan(x)-7=0 for 0<=x<360 are:
x = 65.26 degrees or x = 245.26 degrees.

The number of animals at a shelter from day to day has a mean of 37.6, with a standard deviation of 6.1 animals. The distribution of number of animals is not assumed to be symmetric. Between what two numbers of animals does Chebyshev's Theorem guarantees that we will find at least 89% of the days
Answer:
Between 19.3 and 55.9 animals.
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by \(100(1 - \frac{1}{k^{2}})\).
In this question:
Mean of 37.6, standard deviation of 6.1.
Between what two numbers of animals does Chebyshev's Theorem guarantees that we will find at least 89% of the days?
Within 3 standard deviations of the mean, so:
37.6 - 3*6.1 = 19.3
37.6 + 3*6.1 = 55.9
Between 19.3 and 55.9 animals.

answer the following questions in the picture
a. The chart is prepared below.
b. At the end of 4 years, Ross still owes his parents $1,576.92.
How to calculate interest ?To solve this problem, we need to calculate the balance of Ross's loan at the end of each year.
The balance for each year can be calculated by subtracting the yearly payment from the balance at the beginning of the year and adding the interest earned for the year.
The interest for each year is calculated by multiplying the balance at the beginning of the year by the annual interest rate of 3.2%.
Here are the steps for calculating the balance for each year:
Year 1:
Beginning balance = $2,500.00
Interest for the year = $2,500.00 x 0.032 = $80.00
Ending balance = $2,500.00 + $80.00 - $300.00 = $2,280.00
Year 2:
Beginning balance = $2,280.00
Interest for the year = $2,280.00 x 0.032 = $72.96
Ending balance = $2,280.00 + $72.96 - $300.00 = $2,052.96
Year 3:
Beginning balance = $2,052.96
Interest for the year = $2,052.96 x 0.032 = $65.76
Ending balance = $2,052.96 + $65.76 - $300.00 = $1,818.72
Year 4:
Beginning balance = $1,818.72
Interest for the year = $1,818.72 x 0.032 = $58.20
Ending balance = $1,818.72 + $58.20 - $300.00 = $1,576.92
Here's a table that shows the details:
Year ,principal ,Interest rate, interest, Payment ,annual owing
1 $2,500.00 $80.00 $300.00 $2,280.00
2 $2,280.00 $72.96 $300.00 $2,052.96
3 $2,052.96 $65.76 $300.00 $1,818.72
4 $1,818.72 $58.20 $300.00 $1,576.92

Which set of numbers can represent the side lengths, in centimeters, of a right triangle?
A set of numbers that can represent the side lengths, in centimeters, of a right triangle is any set that satisfies the Pythagorean theorem, where the square of the hypotenuse's length is equal to the sum of the squares of the other two sides.
A right triangle is a type of triangle that contains a 90-degree angle. According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's consider a set of numbers that could represent the side lengths of a right triangle in centimeters.
One possible set could be 3 cm, 4 cm, and 5 cm.
To verify if this set forms a right triangle, we can apply the Pythagorean theorem.
Squaring the length of the shortest side, 3 cm, gives us 9. Squaring the length of the other side, 4 cm, gives us 16.
Adding these two values together gives us 25.
Finally, squaring the length of the hypotenuse, 5 cm, also gives us 25. Since both values are equal, this set of side lengths satisfies the Pythagorean theorem, and hence forms a right triangle.
It's worth mentioning that the set of side lengths forming a right triangle is not limited to just 3 cm, 4 cm, and 5 cm.
There are infinitely many such sets that can be generated by using different combinations of positive integers that satisfy the Pythagorean theorem.
These sets are known as Pythagorean triples.
Some other examples include 5 cm, 12 cm, and 13 cm, or 8 cm, 15 cm, and 17 cm.
In summary, a right triangle can have various sets of side lengths in centimeters, as long as they satisfy the Pythagorean theorem, where the square of the hypotenuse's length is equal to the sum of the squares of the other two sides.

The expression that is equivalent to StartRoot \(8 x^7 y^8\) EndRoot is (\(2 x^3 y^4\) StartRoot 2 x EndRoot)^2.
To understand why this is the case, let's break down each expression and simplify them step by step:
StartRoot \(8 x^7 y^8\) EndRoot:
We can rewrite 8 as \(2^3\), and since the square root can be split over multiplication, we have StartRoot \((2^3) x^7 y^8\) EndRoot. Applying the exponent rule for square roots, we get StartRoot \(2^3\) EndRoot StartRoot \(x^7\) EndRoot StartRoot \(y^8\) EndRoot.
Simplifying further, we have 2 StartRoot \(2 x^3 y^4\) EndRoot StartRoot \(2^2\) EndRoot StartRoot \(x^2\) EndRoot StartRoot \(y^4\) EndRoot. Finally, we obtain 2 \(x^3 y^4\) StartRoot 2 x EndRoot, which is the expression in question.
(\(2 x y^2\) StartRoot 8 x^3 EndRoot)^2:
Expanding the expression inside the parentheses, we have \(2 x y^2\)StartRoot \((2^3) x^3\) EndRoot. Applying the exponent rule for square roots, we get \(2 x y^2\) StartRoot \(2^3\) EndRoot StartRoot \(x^3\) EndRoot.
Simplifying further, we have \(2 x y^2\) StartRoot 2 x EndRoot. Squaring the entire expression, we obtain (\(2 x y^2\) StartRoot 2 x EndRoot)^2.
Therefore, the expression (\(2 x^3 y^4\) StartRoot 2 x EndRoot)^2 is equivalent to StartRoot \(8 x^7 y^8\) EndRoot.

Given: A (-3, 5) and B (4, -2), what is the length of AB?
After considering the given data we come to the conclusion that the length of AB is 12.124 units, under the condition that A (-3, 5) and B (4, -2) are the given coordinates.
The distance between two points in a plane can be found using the distance formula which is an application of the Pythagorean theorem. The formula is given by d=√ ( ((x₂ – x₁ )² + (y₂ – y₁ )²)
Here (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
Applying the given coordinates of A (-3, 5) and B (4, -2), we can evaluate the distance between them as follows:
d = √( (4 - (-3))² + (-2 - 5)² )
= √(7² + (-7)²)
= √(98 + 49)
= √147
= 12.124
Therefore, the length of AB is approximately 12.124 units.

According to Wikipedia, the following are the lengths of terms of the US Presidents that preceded Joe Biden. There is a total of 44. You may have expected to see a total of 45, as Biden is the 46th us President, but Grover Cleveland was considered the 22nd and the 24th President, but is only counted once in this list The 2922 is the length of two full terms and the 1461 is the length of one full term FDR, the 4422 in the table, had actually started his FOURTH term before dying in office The 31 is William Henry Harrison who became ill shortly after his inauguration. His death may have been due to pneumonia Number of US Presidents 12 1 1 Term in Days 4422 2922 2865 2.840 2.728 2.041 2.027 1.886 1,654 1.503 1,461 1.460 1.430 1.419 1 1 12 1 1 1.419 1.262 1,036 969 895 881 492 199 31 TOTAL: 1 1 1 1 1 1 1 1 1 44 Determine the mean, median and mode for this set of data Give each to the nearest whole day Mean = Median = Mode = and With one of the modes being a high value as well as the term of FDR being much higher than all others, was pulled up to a higher value than another of hte measures of central tendency the
The mean of the given data is 1744 days, median of the given data is 1460.5 days, mode of the given data is 1461 days & 4422 days.
To find the mean, median, and mode of the lengths of terms of the US Presidents that preceded Joe Biden:
Mean:
To find the mean, we add up all of the term lengths and divide by the total number of terms:
Mean = (4422 + 2922 + 2865 + 2840 + 2728 + 2041 + 2027 + 1886 + 1654 + 1503 + 1461 + 1460 + 1430 + 1419 + 1262 + 1036 + 969 + 895 + 881 + 492 + 199 + 31) / 44
Mean = 1743.77 days
Median:
To find the median, we need to arrange the term lengths in order from smallest to largest, and then find the middle term. In this case, since we have an even number of terms, we will take the average of the two middle terms:
31 199 492 881 895 969 1036 1262 1419 1430 1460 1461 1503 1654 1886 2027 2041 2728 2840 2865 2922 4422
Median = (1460 + 1461) / 2
Median = 1460.5 days
Mode:
The mode is the most frequently occurring term length. In this case, there are two modes: 1,461 days and 4,422 days.
Since the term length of FDR is much higher than all the other term lengths, it has pulled up the mean to a higher value than the other measures of central tendency. Additionally, the mode being a high value is likely due to the fact that FDR served for more than three terms, which is an outlier in the data set.
