Please help!! With step by step

Sever21 [200]

Answer:

$R=\$145.12$

Step-by-step explanation:

<u>Compound Interest</u>

This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.

The present value PV or the principal can be calculated with

$P=F_a\cdot R$

Solving for R

$\displaystyle R=\frac{P}{F_a}$

Where Fa is computed by

$\displaystyle F_a=\frac{1-(1+i)^{-n}}{i}$

We'll use the provided values but we need to convert them first to monthly payments

$i=7\%=7/(12\cdot 100)=0.00583$

$n=3*12=36$

$\displaystyle F_a=\frac{1-(1+0.00583)^{-36}}{0.00583}$

$F_a=32.386$

Thus, each payment is

$\displaystyle R=\frac{4,700}{32.386}=145.12$

$\boxed{R=\$145.12}$

The length of a rectangle is five times its width. The perimeter of the rectangle is at most 96 cm. Which inequality models the

aivan3 [116]

Let

L--------> the length of the rectangle

W-------> the width of the rectangle

we know that

the perimeter of the rectangle is equal to

$P=2L+2W$

$P\leq 96\ cm$

$(2L+2W)\leq 96$ ---------> equation $1$

$L=5W$ ---------> equation $2$

Substitute equation $2$ in equation $1$

$2*(5W)+2W\leq 96$

therefore

<u>the answer is the option</u>

2w+2⋅(5w)≤96

Find the 30th term of the geometric sequence 100, 80, 64,...

Zinaida [17]

Answer:

0.155

Step-by-step explanation:

nth term of a geometric sequence = ar^n-1

Where,

a = first term

r = common ratio

n = number of terms

Given:

100, 80, 64,...

a = 100

r= 80/100

= 4/5

30th term of a geometric sequence = ar^30-1

= ar^29

= 100 × (4/5)^29

= 100 × (0.8)^29

= 100 × 0.00155

= 0.155

Therefore,

30th term of the geometric progression = 0.155
