Answer:a^2+2ab+b^2

Step-by-step explanation:

First write it out in extended form, (a+b)(a+b) then multiply each term by the other in each parenthesis, such as a*a+b*b+a*b+a*b

Then, once you have done that, simplify it. you will then get the answer a^2+2ab+b^2

Cindy plans to invest for 10 years at 1.5%, compounded annually. If she hopes to have $10,000 after 10 years, how much

iogann1982 [59]

Answer:

Use the formula for calculating compound interest PN=P0(1+rk)Nk where P0 is the unknown, PN=10,000, N=10, k=1, and r=0.015. Substitute the values into the formula and simplify.

10000=P(1+0.0151)1⋅10

10000=P(1.015)10

10000=P(1.16054...)

8616.67=P

Therefore, rounded to the nearest dollar, the initial investment needs to be $8617 to have $10,000 in 10 years.

HELP !!!!!!!!!!!!!!!!!!

4vir4ik [10]

Answer:

<u>answer is C ( </u> $3^{4}$ <u> )</u>

Step-by-step explanation:

so here is how you do it.

first you need to find out what $3^{8}$ is

which is the same as 3 X 3 X 3 X 3 X 3 X 3 X 3 X 3

the answer to that is 6,561

then you have to square root that

which looks like this

$\sqrt{6,561}$

which is 81

which means that you have to find the same expression that equals to 81

I then did $3^{4}$ (C) to see if the answer will be 81 and it is. so your answer is C
