Answers
Answer:?=93/14
Step-by-step explanation:
the ? is the variable in this equation so we have to solve for it
1. distributive property ->
5(?+3) = 5?+15
?(6+3) = 9?
so 5?+15+9?=108 -> 14?+15=108
2. then solve,
14? -15 = 108 -15
14?=93
?=93/14

Laterfah and Eric Lewis have obtained a mortgage loan at a 5.5% annual interest rate for 25 years. The home's selling price is $175,000, and they need a 20% down payment. The bank will allow them to finance the closing costs as part of the mortgage. What is the actual amount financed with the mortgage? Find the closing cost and the total amount of the mortgage if the closing costs are financed.
Answers
Answer:
The selling price of the house is $175,000 and they need to make a 20% down payment, so the down payment amount is:
Down payment = 20% x $175,000 = $35,000
To find the amount financed with the mortgage, we need to subtract the down payment from the selling price:
Amount financed = Selling price - Down payment
Amount financed = $175,000 - $35,000
Amount financed = $140,000
Next, we need to calculate the closing costs. Let's assume the closing costs are 3% of the selling price:
Closing costs = 3% x $175,000 = $5,250
Since the bank allows them to finance the closing costs as part of the mortgage, we need to add the closing costs to the amount financed:
Total amount of the mortgage = Amount financed + Closing costs
Total amount of the mortgage = $140,000 + $5,250
Total amount of the mortgage = $145,250
Therefore, the actual amount financed with the mortgage is $140,000, the closing costs are $5,250, and the total amount of the mortgage if the closing costs are financed is $145,250.
Show that y=2x^3−6x+10 is a solution to the differential equation: −y′′−xy′′−2y'=−24x^2.
Answers
The equation y=2x^3−6x+10 is a solution to the differential equation: −y′′−xy′′−2y'=−24x^2.
To show that y = 2x^3 - 6x + 10 is a solution to the given differential equation, we need to verify that when we substitute y and its derivatives into the differential equation, the equation holds true.
First, let's find the first and second derivatives of y:
y' = d/dx (2x^3 - 6x + 10) = 6x^2 - 6
y'' = d/dx (6x^2 - 6) = 12x
Now, let's substitute y, y', and y'' into the differential equation:
-(y'') - x(y'') - 2y' = -24x^2
Substituting the values:
-(12x) - x(12x) - 2(6x^2 - 6) = -24x^2
Simplifying:
-12x - 12x^2 - 12x^2 + 12 = -24x^2
Combining like terms:
-24x^2 - 24x + 12 = -24x^2
We can see that the equation holds true, as both sides of the equation are equal.
Therefore, we have shown that y = 2x^3 - 6x + 10 is a solution to the differential equation -y'' - xy'' - 2y' = -24x^2.

Vector w is not in the subspace span{V1, V2, V3} because the rightmost column of the augmented matrix of the system X1 V1 + X2 V2 + X3 V3 = w is not a pivot column. The correct answer is A.

[1 1 -1 | 1]
[0 1 2 | 0]

The function \(y=0.3^x\) represents exponential growth with the initial value equal to 1, the decay factor equal to 0.3, and the rate equal to 0.7.
Population Growth Equation
The formula for the Population Growth Equation is:
\(P_f=P_o*(1+\frac{R}{100}) ^t\)
Pf= future population
Po=initial population
r=growth rate
t= time (years)
growth or decay factor = (1 ±r)
When 1+R > 1, the equation represents growth, while 1+R < 1 the equation represents decay.
The question gives:

Answers
The solutions to the equation 3x^2 - 9x - 12 = 0 are x = 4 and x = -1.
To solve the quadratic equation 3x^2 - 9x - 12 = 0, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a),
where a, b, and c are the coefficients of the quadratic equation.
In this case, a = 3, b = -9, and c = -12. Substituting these values into the quadratic formula, we have:
x = (-(-9) ± √((-9)^2 - 4 * 3 * (-12))) / (2 * 3)
= (9 ± √(81 + 144)) / 6
= (9 ± √(225)) / 6
= (9 ± 15) / 6.
We have two possible solutions:
For the positive root:
x = (9 + 15) / 6
= 24 / 6
= 4.
For the negative root:
x = (9 - 15) / 6
= -6 / 6
= -1.

drag the tiles to the boxes to form correct pairs. not all tiles will be used. determine each segment length in right triangle . 14 7
Answers
To determine the segment length in a right triangle, you would need to use the Pythagorean theorem which states that the sum of the squares of the lengths of the two shorter sides (legs) of a right triangle is equal to the square of the length of the longest side (hypotenuse).
In this case, if we assume that 14 is the length of the hypotenuse and 7 is one of the legs, we can solve for the other leg using the Pythagorean theorem:
14²= 7² + x²
196 = 49 + x²
x² = 147
x = √147
Therefore, the length of the other leg in the right triangle is √147.
In this case, let's consider the side lengths 14 and 7 as the two legs of the right triangle. To find the hypotenuse, apply the Pythagorean theorem:
Hypotenuse² = Leg₁² + Leg₂²
Hypotenuse² = 14² + 7²
Hypotenuse² = 196 + 49
Hypotenuse² = 245
Hypotenuse = √245
So, drag the tiles "14" and "7" to the boxes representing the legs, and "√245" to the box representing the hypotenuse. This forms the correct pairs for the segment lengths in the right triangle.

No, there is no constant of proportionality.
Answers
The linear relationship between time and distance can be considered proportional. The constant of proportionality in this case is 4.
In a proportional relationship, the ratio between the two quantities remains constant. Here, as time increases by 2 hours, the distance also increases by 8 miles. Let's calculate the ratio of distance to time for each pair of values:
For the first pair (2 hours, 8 miles):
Ratio = distance / time = 8 miles / 2 hours = 4 miles/hour
For the second pair (4 hours, 16 miles):
Ratio = distance / time = 16 miles / 4 hours = 4 miles/hour
For the third pair (6 hours, 24 miles):
Ratio = distance / time = 24 miles / 6 hours = 4 miles/hour
For the fourth pair (8 hours, 32 miles):
Ratio = distance / time = 32 miles / 8 hours = 4 miles/hour
As we can see, the ratio of distance to time remains constant at 4 miles per hour for all the pairs. This indicates a proportional relationship between time and distance.
Therefore, the linear relationship is also proportional, and the constant of proportionality is 4.

Answer:
∠A = 48
∠B = 58
∠BCA = 74
Step-by-step explanation:
m∠BCD is an exterior angle of a triangle while m∠A and m∠B are opposite interior angles of m∠BCD
Exterior angles of a triangle are equal to the sum of the opposite interior angles, hence m∠BCD = m∠A + m∠B
Knowing this we can create an equation to solve for y
∠BCA = 106° , ∠B = 3y + 22 and ∠A = 4y
If m∠BCD = m∠A + m∠B then 106 = 3y + 22 + 4y
106 = 3y + 22 + 4y we now solve for y
combine like terms ( 3y + 4y = 7y )
106 = 7y + 22
subtract 22 from both sides
84 = 7y
divide both sides by 7
12 = y
Now we can find the measures of ∠A and ∠B by plugging in the value of y into their expressions
∠A = 4y
y = 12
∠A = 4(12) = 48°
∠B = 3y + 22
y = 12
∠B = 3(12) + 22
3 * 12 = 36
∠B = 36 + 22 = 58°
Finally we want to find the measure of ∠BCA
∠BCA and ∠BCD are supplementary angles
Supplementary angles add up to 180°
Hence ∠BCA + ∠BCD = 180
∠BCD = 106°
∠BCA + 106 = 180
subtract 106 from both sides
∠BCA = 74°°

The correct code to swap elements 0 and 1 in the given array {7, 8, 10, 11, 4, 3} would be: int save = array[0];array[0] = array[1];array[1] = save;
The code above uses a temporary variable "save" to store the value of the first element of the array, then assigns the value of the second element to the first element, and finally assigns the value of "save" (which holds the original value of the first element) to the second element.
The other lines of code following this swap code would perform additional operations on the array, but they do not correctly swap the first two elements of the array.
For example, the line array[0] = array[1]; in the given code only assigns the value of the second element to the first element, effectively overwriting the original value of the first element before it can be saved. Similarly, the line array[1] = array[0]; then assigns the overwritten value of the first element to the second element, resulting in no swap at all.
Therefore, the correct code to swap the first two elements of the array is the code I mentioned at the beginning of this answer.
