The length of a rectangle is 6 yd more than twice the width x. The area is 416 yd2. Find the dimensions of the rectangle.
kati45 [8]

Answer:

13 yds * 32 yds

Step-by-step explanation:

A=area, l=length, w=width

A=w*l

l=6+2w

A=w*(6+2w)

A=6w+2w^2

416=6w+2w^2

416/2=(6w+2w^2)/2

208=3w+w^2

208-208=3w+w^2-208

w^2+3w-208=0

w^2+16w-13w-208=0

w(w+16)-13(w+16)=0

(w-13)(w+16)=0 ==> w+16=0 ==> w=-16, w can't be negative.

w-13=0

<u>w=13</u>

l=6+2w

l=6+2(13)

l=6+26

<u>l=32</u>

Dimensions: 13 * 32

erastova [34]

Given the principal as $95, annual rate as 3% and term of the annuity as10yrs/

#First we determine the effective rate per payment period

i_{12}=0.03/12=0.0025

# Annuity formula is given as:

A=P[{\frac{(1+i)^n-1)}{i}}], \ i=0.0025, n=12\times10=120,p=95\\\\A=95[{\frac{(1.0025)^{120}-1)}{0.0025}}]\\\\A=13275.43

Hence, Veronica needs to save $13,275.43
