Answer:
there is no mistake
Step-by-step explanation:
this seems weird ik but i dont think there is even a mistake? the answer is definitely -7/2 or -3.5
Answer:
a. Problem A > Problem B
Step-by-step explanation:
Problem A:
f(x) = x3 + 5
f(-2) = (-2)3 + 5
f(-2) = (-6) + 5
f(-2) = -1
Problem B:
f(x) = x2 - 2
f(-2) = (-2)2 - 2
f(-2) = (-4) - 2
f(-2) = -6
8 ^ (-2) = 1 / 64
<span>4 ^ (-3) = 1 / 64</span>
Solution
For this case we can use the following formula:
![A=P(1+\frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
Where:
P= 400800 = present value
A= future value
r= 0.055 interest rate
n= 4, number of times that the interest is compund in a year (quarterly)
t= 4 years
Replacing we got:
![A=400800(1+\frac{0.055}{4})^{4\cdot4}=498679.58](https://tex.z-dn.net/?f=A%3D400800%281%2B%5Cfrac%7B0.055%7D%7B4%7D%29%5E%7B4%5Ccdot4%7D%3D498679.58)
then the interest would be:
The answer from let's to greatest is 3/12,4/5, 5/6
