Answer:

Step-by-step explanation:

Use the Pythagorean Theorem which states

a² + b² = c²

then plug in your given terms

a² + 5.6² = 10.6²

find the squares

a² + 31.36 = 112.36

subtract 31.36 from 112.36 to find your a²

a² = 81

then find the square root of 81, which is 9 becuase 9 x 9 is 81

Jayden earned some money doing odd jobs last summer and put it in a savings account that earns 12% interest compounded monthly.

aivan3 [116]

Answer:

$220.18

Step-by-step explanation:

The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:

$A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}$

In Jayden's case:

A(n)=$400
r=12%=0.12
n=5 years
k=12 Months

We want to determine the amount Jayden put in the savings account.

$400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\$

$P=\$220.18$

Jayden earned $220.18 from doing odd jobs.
