A graduating high school student decides to take a year off and work to save money for college. The student plans to invest all
Anika [276]

Answer:

amount = 407 per month

Step-by-step explanation:

given data

future value = $5000

interest rate = 6% = \frac{0.06}{4} = 0.015

time = 12 months = 4 compound per year

solution

we use here formula that is

amount = future value × \frac{r}{(1+r)^t-1}   .......................1

put here value and we get

amount = 5000 × \frac{0.015}{(1+0.015)^{4}-1}  

amount = 1222 per quarter

or amount = 407 per month

Simplify p^-8/7^-2q^-9
ExtremeBDS [4]

Answer:

\frac{7^2}{p^8 \cdot q^9}

Step-by-step explanation:

\frac{p^{-8}}{7^{-2}} \cdot q^{-9} = \frac{\frac{1}{p^8}}{\frac{1}{7^2}} \cdot \frac{1}{q^9} = \frac{7^2}{p^8 \cdot q^9} by the definition of negative exponents: a^{-b} = \frac{1}{a^b} for all a,b so long as a\ne 0.

Which equation results from taking the square root of both sides of (x + 9)2 = 25?
Alex_Xolod [135]

Answer:

√2.37+ 3 √9 = √5. 3 is the last one

x+9 =+25

Step-by-step explanation:

(x+9)2= 25   This means x= 3.5 and the square root of x = √3.5 = 1.87 square root of 9 x 2 = √18 =4.24

We can also see 18+7 =25

√5.65 √5

this is 25 = 5 so it's the last one.

as 2.37+ 3 √9 = √5. 3
