<span>L=2W-5
LW=150
(2W+5)W=150
2W^2+5W-150=0
(2W-15)(W+10)=0
2W-15=0                </span>2W=15<span>W=7.5 ANS. FOR THE WIDTH.
L=2*7.5+5

Aaron invested $740 in an account paying an interest rate of 5%
vlada-n [284]

The amount of money   Justin would have in his account than Aaron, to the nearest dollar is $0

What is the future value formula for continuous compounding cash flow?

The future value, which is used to determine the worth of this investment of $740 made now in 18 years is as shown below:

FV=PV*e^(rt)

FV=the worth of the investment in 18 years=unknown

PV=the amount invested today=$740

e=mathematical exponential value=2.7182818

r=rate of interest which compounded continuously=5%

t=time of investment in years=18

FV=$740*2.7182818^(5%*18)

FV=$740*2.7182818^(0.90)

FV=$740*2.459603087981220

FV=$1,820.11

Justin:

FV=PV*(1+r/m)^(n*m)

PV=$740

r=5%

m=number of times in a year that interest is compounded=365

m=number of years=18

FV=$740*(1+5%/365)^(18*365)

FV=$1,819.99

difference=$1,820.11-$1,819.99

difference=$0.12($0 to the nearest dollar)

Write equations for the horizontal and vertical lines passing through the point (-6,1)
Oksanka [162]

Answer:

y = 1 and x = - 6

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c ( where c is the value of the y- coordinates the line passes through )

The line passes through (- 6, 1 ) with y- coordinate 1 , then

y = 1 ← equation of horizontal line

The equation of a vertical line parallel to the y- axis is

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, 1 ) with x- coordinate - 6 , then

x = - 6  ← is equation of vertical line
