Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)
![P(1+r)^t](https://tex.z-dn.net/?f=P%281%2Br%29%5Et)
$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
<u>How much she'll owe in 4 years</u>
P = 300
r = 0.15
n = 12
t = 4
![P(1+\frac{r}{n})^{nt}=300(1+\frac{0.15}{12})^{12 \times 4}](https://tex.z-dn.net/?f=P%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D%3D300%281%2B%5Cfrac%7B0.15%7D%7B12%7D%29%5E%7B12%20%5Ctimes%204%7D)
= $544.61 (to the nearest cent)
<u>Yearly compounding interest rate</u>
![P(1+r)^t](https://tex.z-dn.net/?f=P%281%2Br%29%5Et)
<u>How much she'll owe in 4 years at yearly compounding interest</u>
![P(1+r)^t=300(1+0.15)^4](https://tex.z-dn.net/?f=P%281%2Br%29%5Et%3D300%281%2B0.15%29%5E4)
= $524.70 (to the nearest cent)

Answer:
![\large \boxed{\sf \bf \ \ y=3x^2-6x-1 \ \ }](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%5Csf%20%5Cbf%20%5C%20%5C%20y%3D3x%5E2-6x-1%20%5C%20%5C%20%7D)
Step-by-step explanation:
Hello, please consider the following.
We can read from the graph that the vertex is (1,-4) , it means that the equation is, a being a real number.
![y=a(x-1)^2-4](https://tex.z-dn.net/?f=y%3Da%28x-1%29%5E2-4)
And the point (0,-1) is on the graph so we can write.
![a\cdot 1^2-4=-1 \\\\a-4+4=-1+4\\\\a = 3](https://tex.z-dn.net/?f=a%5Ccdot%201%5E2-4%3D-1%20%5C%5C%5C%5Ca-4%2B4%3D-1%2B4%5C%5C%5C%5Ca%20%3D%203)
So the equation is.
![y=3(x-1)^2-4\\\\=3(x^2-2x+1)-4\\\\=3x^2-6x+3-4\\\\=3x^2-6x-1\\\\=\boxed{3}x^2\boxed{-6}x\boxed{-1}](https://tex.z-dn.net/?f=y%3D3%28x-1%29%5E2-4%5C%5C%5C%5C%3D3%28x%5E2-2x%2B1%29-4%5C%5C%5C%5C%3D3x%5E2-6x%2B3-4%5C%5C%5C%5C%3D3x%5E2-6x-1%5C%5C%5C%5C%3D%5Cboxed%7B3%7Dx%5E2%5Cboxed%7B-6%7Dx%5Cboxed%7B-1%7D)
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
D
Step-by-step explanation:
because if you unfold the left corner at the top it just becomes a regular rectangle, 15 by 10. 15 x 2 plus 10 x 2 = 54. and 54 x 1.19 is $64.26 therefor it is D.
I actually did the math this time i promise.
