If F(x) =8+11 X-3X², finda. What is F (5)? b. What is F (x + b)?c. What is F (-3)?

Answers

Answer 1

[tex]\begin{gathered} \text{Given} \\ F(x)=8+11x-3x^2 \end{gathered}[/tex]

a. Solve for F(5).

To solve for F(5), substitute x = 5 to the given function, and evaluate accordingly to the operation

[tex]\begin{gathered} F(x)=8+11x-3x^2 \\ F(5)=8+11(5)-3(5)^2 \\ F(5)=8+55-3(25) \\ F(5)=63-75 \\ F(5)=-12 \end{gathered}[/tex]

b. Solve for F(x+b)

Again we substitute the paremeters by x+b to the given function, and we get

[tex]\begin{gathered} F(x)=8+11x-3x^2 \\ F(x+b)=8+11(x+b)-3(x+b)^2 \\ F(x+b)=8+11x+11b-3(x^2+2xb+b^2) \\ F(x+b)=8+11x+11b-3x^2-6xb-3b^2 \\ \\ \text{Since we cannot simplify further, we just rearrange} \\ \text{the final answer according to the degree of the terms} \\ F(x+b)=-3x^2-3b^2-6xb+11x+11b+8 \end{gathered}[/tex]

c. Solve for F(-3)

Substitute x = -3

[tex]\begin{gathered} F(x)=8+11x-3x^2 \\ F(-3)=8+11(-3)-3(-3)^2 \\ F(-3)=8-33-3(9) \\ F(-3)=-25-27 \\ F(-3)=-52 \end{gathered}[/tex]

Angel's bank gave her a 4 year add on interest loan for $7,640 to pay for new equipment for her antiques restoration business. The annual interest rate is 5.27% How much interest will she pay on the loan? $_______How much would her monthly payments be? $________(round to nearest cent)

Answers

From the information given,

Principal = 7640

Number of years = 4

Recall, 1 year = 12 months

4 years = 4 * 12 = 48 months

rate = 5.27/100 = 0.0527

The amount of the principal to be paid each month = 7640/48 = 159.17

Amount of interest owed each month = (7640 * 0.0527)/12 = 33.55

Amount required to be paid by the borrower each month = 159.17 + 33.55 = 192.72

Total interest to be paid on the loan = 7640 * 0.0527 * 4 = 1610.51

The first answer is $1610.51

The second answer is $33.55

Ellie earned a score of 590 on Exam A that had a mean of 650 and a standarddeviation of 25. She is about to take Exam B that has a mean of 63 and a standarddeviation of 20. How well must Ellie score on Exam B in order to do equivalently wellas she did on Exam A? Assume that scores on each exam are normally distributed.

Answers

Answer

15

Ellie needs to score 15 on Exam B in order to do equivalently as well as she did on Exam A.

Explanation

Since both distributions are normally distributed, we will use the standardized scores of Ellie on both exams to answer this question.

The standardized score for any value is the value minus the mean then divided by the standard deviation.

z = (x - μ)/σ

where

z = standardized score or z-score

x = score in the distribution or in the exam

μ = Mean

σ = Standard deviation

So, we will find the standardized score on Exam A and use that standardized score to find the equivalent score on exam B.

For exam A,

z = ?

x = 590

μ = 650

σ = 25

z = (x - μ)/σ

z = (590 - 650)/25

z = (-60/25) = -2.4

For exam B, to find the equivalent score with a standardized score of -2.4

z = -2.4

x = ?

μ = 63

σ = 20

z = (x - μ)/σ

-2.4 = (x - 63)/20

(x - 63)/20 = -2.4

Cross multiply

x - 63 = (20) (-2.4)

x - 63 = -48

x = 63 - 48

x = 15

Hope this Helps!!!

Find the area of quadrilateral math with vertices M(7, 6), A(3, - 2), T(- 7, 1) and H(- 1, 9)

Answers

Lets draw a picture of our quadrilateral:

In order to find the area, we can divide our parallelogram in 2 triangles:

The area of triangle AHT is given by

[tex]\text{Area }\Delta AHT=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))[/tex]

where

[tex]\begin{gathered} (x_1,y_1)=(3,-2)=A \\ (x_2,y_2)=(-1,9)=H \\ (x_3,y_3)=(-7,1)=T \end{gathered}[/tex]

By substituting these points into the given formula, we get

[tex]\text{Area }\Delta AHT=\frac{1}{2}(3_{}(9_{}-(-7))-1((-7)-(-2))-7((-2)-9))[/tex]

which gives

[tex]\begin{gathered} \text{Area }\Delta AHT=\frac{1}{2}(3_{}(16)-1(-5)-7(-11)) \\ \text{Area }\Delta AHT=\frac{1}{2}(48+5+77) \\ \text{Area }\Delta AHT=\frac{130}{2} \\ \text{Area }\Delta AHT=65 \end{gathered}[/tex]

Similarly, for the area of triangle AHM, we can choose

[tex]\begin{gathered} (x_1,y_1)=(3,-2)=A \\ (x_2,y_2)=(-1,9)=H \\ (x_3,y_3)=(7,6)=M \end{gathered}[/tex]

By substuting in our area formula, we get

[tex]\text{Area }\Delta AHM=\frac{1}{2}(3_{}(9_{}-6)-1(6-(-2))+7((-2)-9))[/tex]

which gives

[tex]\begin{gathered} \text{Area }\Delta AHM=\frac{1}{2}(3_{}(3)-1(8)+7(-11) \\ \text{Area }\Delta AHM=\frac{1}{2}(9-8-77) \\ \text{Area }\Delta AHM=\frac{76}{2} \\ \text{Area }\Delta AHM=38 \end{gathered}[/tex]

Then, the total area is given by

[tex]\begin{gathered} A=\text{Area }\Delta AHT+\text{Area }\Delta\text{AHM} \\ A=65+38 \\ A=103 \end{gathered}[/tex]

then, the answer is 103 units squared.

Rich is attending a 4-year college. As a freshman, he was approved for a 10-year, federal unsubsidized student loan in the amount of $7,900 at 4.29%. He knows he has the
option of beginning repayment of the loan in 4.5 years. He also knows that during this non-payment time, Interest will accrue at 4.29%.
If Rich decides to make no payments during the 4.5 years, the Interest will be capitalized at the end of that period.
a. What will the new principal be when he begins making loan payments?
b. How much interest will he pay over the life of the loan?

Answers

The $7,900 10 year, federal unsubsidized student loan has a new principal and interest paid as follows;

a. The new principal of the loan after 4.5 years is approximately $9,543.75

b. The interest on the loan is approximately $3,016.27

What are unsubsidized student loans?

Unsubsidized loans are loans that are not based on financial need of undergraduate and graduate students.

The future value of the loan is found using the formula;

[tex]FV = PV\cdot \left(1+\dfrac{r}{100} \right)^n[/tex]

Where;

FV = The future value of the loan

PV = The present value of the loan = $7,900

r = The interest rate of the loan = 4.29%

n = The number of years = 4.5 years

Which gives;

[tex]FV = 7900\times \left(1+\dfrac{4.29}{100} \right)^{4.5}\approx 9543.75[/tex]

The new principal of the loan when he begins to make loan payments is $9,543.75

b. The payment (amortization) formula is presented as follows;

[tex]A = P\cdot \dfrac{r\cdot (1+r)^n}{(1+r)^n-1}[/tex]

Which gives;

[tex]A = 9543.75\times \dfrac{0.0429\cdot (1+0.0429)^{5.5}}{(1+0.0429)^{5.5}}{-1} \approx 1984.78[/tex]

The amount paid annually ≈ $1,984.78

The amount paid in 5.5 years ≈ 1984.78 × 5.5 = 10,916.27

The interest paid = $10,916.27 - $7,900 = $3,016.27

y=f(x) is the particular solution to the differential equation dy/dx=(x(y-1))/4, with the initial condition of f(1)=3. write an equation for the line tangent to the graph of f at the point (1,3) and use it to approximate f(1,4)

Answers

We are given the following differential equation:

[tex]\frac{dy}{dx}=\frac{x(y-1)}{4}[/tex]

Since this equation gives the value of the slope of the tangent line at any point (x,y). To determine the equation of such line we need to use the general form of a line equation:

[tex]y=mx+b[/tex]

Since in a tangent line the slope is equivalent to the derivative we may replace that into eh line equation like this:

[tex]y=\frac{dy}{dx}x+b[/tex]

Now we determine the value of dy/dx at the point (1,3):

[tex]\frac{dy}{dx}=\frac{(1)(3-1)}{4}=\frac{2}{4}=\frac{1}{2}[/tex]

Replacing into the equation of the line:

[tex]y=\frac{1}{2}x+b[/tex]

Now we replace the point (1,3) to get the value of "b":

[tex]3=\frac{1}{2}(1)+b[/tex]

Solving for "b":

[tex]\begin{gathered} 3=\frac{1}{2}+b \\ 3-\frac{1}{2}=b \\ \frac{5}{2}=b \end{gathered}[/tex]

Replacing into the line equation:

[tex]y=\frac{1}{2}x+\frac{5}{2}[/tex]

And thus we get the equation of the tangent line.

To approximate the value of f(1.4) we replace the value x = 1.4 in the equation of the tangent line:

[tex]y=\frac{1}{2}(1.4)+\frac{5}{2}[/tex]

Solving the operation:

[tex]y=3.2[/tex]

Therefore, the approximate value of f(1.4) is 3.2

                                 m∠A = 55°

                                 BC = 5 units

          SinA = BC / AB

         sin55° = 5/AB

    or,

               AB = 5/ Sin55°

                   as, Sin55° = 0.81915204

               AB = 5/0.81915204

               AB = 6.1038

Thus,

          For a given Right angled triangle, equation for hypotenuse is,  

AB = 5/ Sin55°

whats the simplest form of— 3х + 7 – 2x +11 — x

Answers

The given expression is

[tex]-3x+7-2x+11-x[/tex]

We have to reduce like terms. -3x, -2x, and -x are like terms. 7 and 11 are like terms.

[tex]-3x-2x-x+7+11=-6x+18[/tex]

Then, we factor out the greatest common factor, observe that 6 is the greatest common factor

[tex]6(-x+3)[/tex]Hence, the simplest form is 6(-x + 3).
