Greater than 90 and less than 180 degrees is obtuse .

Answer:

B) obtuse

Step-by-step explanation:

We can see that angle SRT is much larger than 90 degrees, but smaller than a straight line.  This makes it an obtuse angle.

A right angle is an angle that is exactly 90 degrees.

An obtuse angle is an angle between 90-180 degrees.

A straight angle is an angle that is exactly 180 degrees.

An acute angle is an angle that is less than 90 degrees.

If, Mnop is a square, then the values of t and f if t = f will be t = \(17.5\)° and f=\(12\)°

Square:

There are many objects around us that have the shape of a square. Each square shape is identified by its equal sides and interior angles that are equal to 90°.

A square is a closed figure with four equal sides and the interior angles of the square are equal to 90°. A square can have a wide variety of properties.

According to the problem

4t+20=90

4t=90-20 = 70

t=(70/4)=17.5

Now,

t = 17.5 So,

7f+6=90

=> 7f=84

=>f = (84/7)=12

Therefore, the value of t = \(17.5\)° and f=\(12\)°

Consecutive angles of a parallelogram are supplementary.

Answer: (3x-2)(3x+2)

I knew the answer it was just hard to explain all of it. Sorry if this doesn't help

Thus, the equation of the line is: \(y - A = B(x - C)\)

where A = 0, C = 5 - 10/a, and B = -5/a. Substituting \(a^2 = 10\), we get:

\(A = 0\)

\(B = -5/a = -5/\sqrt(a^2) = -5/\sqrt(10)\\)

\(c = 5-10/a= 5-\sqrt{(100/a^{2} )} = 5-\sqrt{10}\)

An equation is a mathematical statement that uses symbols, numbers, and operations to show that two expressions are equal. It usually contains one or more variables, which represent unknown values that need to be solved for. Equations are used in a wide range of mathematical fields, such as algebra, geometry, calculus, and physics, to model real-world situations and solve problems. Some common examples of equations include:

Linear equation: y = mx + b.

by the question.

Let A = (a, 0) and C = (0, c) be the points of intersection with the x and y axes, respectively. Then the equation of the line passing through (2,5) and (a,0) is given by:

\((y - 5)/(0 - 5) = (x - 2)/(a - 2)\)

Simplifying, we get:

\(y = (-5/a)x + (5a/a - 10)\)

\(y = (-5/a)x + (5 - 10/a)\)

Now, we can find the coordinates of A and C by setting y = 0 and x = 0, respectively:

\(A = (a, 0) \geq 0 = (-5/a)a + (5 - 10/a) \geq a^2 = 10\)

\(C = (0, c) \geq c = (-5/2)(0) + (5 - 10/a) \geq c = 5 - 10/a\)

The evaluated lateral surface area is 261.8 square meters, under the condition that the base length is 20 m and height is 13 m.

The lateral surface area of a cylinder is given by the formula 2πrh
Here,
r = radius of the base
h = height of the cylinder.
For the given case, the base length is 20 m and height is 13 m. Then the base length is stated  instead of the radius, we have  to evaluate the radius first.
The radius of a cylinder can be found applying the formula r = l/2π
Here,
l = base length.
So, staging l = 20 m
, we get
r = 20/(2π)
≈ 3.18 m
Now that we have received the radius and height, we can evaluate the lateral surface area applying the formula mentioned above.
Staging
r = 3.18 m
h = 13 m,
we get:

The balance in the fund at the end of 23 years, with monthly deposits of $1,150 and a 3.25% annual interest rate, is approximately $449,069.51. The amount of interest earned over the period is approximately $420,630.49.

a. The balance in the fund at the end of the 23-year period, considering a monthly deposit of $1,150 and an annual interest rate of 3.25% compounded annually, is approximately $449,069.51.

To calculate the balance, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where A is the accumulated balance, P is the monthly deposit, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.

In this case, we have monthly deposits, so we need to convert the annual interest rate to a monthly rate:

Monthly interest rate = (1 + 0.0325)^(1/12) - 1 = 0.002683

Using this monthly interest rate, we can calculate the accumulated balance over the 23-year period:

A = 1150 * [(1 + 0.002683)^(12*23) - 1] / 0.002683 = $449,069.51

Therefore, the balance in the fund at the end of the 23-year period is approximately $449,069.51.

b. The amount of interest earned over the 23-year period can be calculated by subtracting the total deposits from the accumulated balance:

Interest earned = (Monthly deposit * Number of months * Number of years) - Accumulated balance

Interest earned = (1150 * 12 * 23) - 449069.51 = $420,630.49

Therefore, the amount of interest earned over the 23-year period is approximately $420,630.49.

From the question, we have the following parameters that can be used in our computation:

Initial value, a = $20

Rate, r = 5%

Time, t = 5 years

The cost can be calculated using the following exponential function

C(t) = a * (1 + r)^t

Substitute the known values in the above equation, so, we have the following representation

C(5) = 20 * (1 + 5%)^5

Answer:

\( {10}^{th} \: term = \frac{5}{512} \)

Step-by-step explanation:

geometric progression formula:

\( {n}^{th} \: term = ar ^{n - 1} \)

given:

common ratio, r = 1/2

\(first \: term \: = 5\)

1) find the value of a

\( {n}^{th} \: term \: = a {r}^{n - 1} \)

we're finding the 1st term, so substitute 1 into n:

\( {1}^{st} \: term = a( \frac{1}{2} ) {}^{1 - 1} \)

first term is 5. so we substitute 5 into the equation:

\(5 = a(1)\)

\(a = 5\)

2) find the 10th term

we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:

\( {10}^{th} \: term = 5( \frac{1}{2} ) {}^{10 - 1} \)

\( {10}^{th} \: term = 5( \frac{1}{512} )\)

\( {10}^{th} \: term = \frac{5}{512} \)

A graph that is commonly used to compare the relationship between a categorical and a quantitative variable is a box plot, also known as a box-and-whisker plot.

A type of graph is particularly useful for visually displaying the distribution, central tendency, and variability of the quantitative variable across different categories.
In a box plot, the categorical variable is represented along the x-axis, while the quantitative variable is represented on the y-axis. For each category, a box is drawn to show the interquartile range (IQR), which contains the middle 50% of the data. The line inside the box represents the median, a measure of central tendency. Whiskers extending from the box show the range of the data, excluding possible outliers.
This graphical representation allows for easy comparison between categories, making it an effective tool for analyzing the relationship between a categorical and a quantitative variable.
