Let's compute the total loan cost:

https://www.1728.com/loanfrm4.htm

227.50 per month * 60 months = $13,650.00 TOTAL LOAN COST

I think the loan payment formula cannot be solved for rate and must be solved through trial and error.

Here is an online loan calculator:

It says the answer is 15.299 which would be

15.3% rounded

Answer:

The true annual interest rate is 15.3%.

Step-by-step explanation:

Given information: Loan amount = $9,500, Monthly payments = $227.50, Time of loan contract = 5 years.

The formula for monthly payment is

$M.P.=\frac{P.V.(\frac{r}{12})}{1-(1+\frac{r}{12})^{12n}}$

Where, M.P. is monthly payment, P.V. is present value, r is rate of interest, n is number of years.

$227.50=\frac{9500(\frac{r}{12})}{1-(1+\frac{r}{12})^{-12(5)}}$

Using graphing calculator we get

$r=0.153$

$r=15.3\%$

Therefore the true annual interest rate is 15.3%.

The green triangle is a dilation of the red triangle with a scale factor of s=1/3 and the center of dilation is at the point (4,

klasskru [66]

Given:

The scale factor is $s=\dfrac{1}{3}$ and the center of dilation is at the point (4,2).

Red is original figure and green is dilated figure.

To find:

The coordinates of point C' and point A.

Solution:

Rule of dilation: If a figure is dilated with a scale factor k and the center of dilation is at the point (a,b), then

$(x,y)\to (k(x-a)+a,k(y-b)+b)$

According to the given information, the scale factor is $\dfrac{1}{3}$ and the center of dilation is at (4,2).

$(x,y)\to (\dfrac{1}{3}(x-4)+4,\dfrac{1}{3}(y-2)+2)$ ...(i)

Let us assume the vertices of red triangle are A(m,n), B(10,14) and C(-2,11).

Using (i), we get

$C(-2,11)\to C'(\dfrac{1}{3}(-2-4)+4,\dfrac{1}{3}(11-2)+2)$

$C(-2,11)\to C'(\dfrac{1}{3}(-6)+4,\dfrac{1}{3}(9)+2)$

$C(-2,11)\to C'(-2+4,3+2)$

$C(-2,11)\to C'(2,5)$

Therefore, the coordinates of Point C' are C'(2,5).

We assumed that point A is A(m,n).

Using (i), we get

$A(m,n)\to A'(\dfrac{1}{3}(m-4)+4,\dfrac{1}{3}(n-2)+2)$

From the given figure it is clear that the image of point A is (8,4).

$A'(\dfrac{1}{3}(m-4)+4,\dfrac{1}{3}(n-2)+2)=A'(8,4)$

On comparing both sides, we get

$\dfrac{1}{3}(m-4)+4=8$

$\dfrac{1}{3}(m-4)=8-4$

$(m-4)=3(4)$

$m=12+4$

$m=16$

And,

$\dfrac{1}{3}(n-2)+2=4$

$\dfrac{1}{3}(n-2)=4-2$

$(n-2)=3(2)$

$n=6+2$

$n=8$

Therefore, the coordinates of point A are (16,8).
