Using technology, determine the monthly payment on a 35 month loan of $28,000 at 8.1% compounded annually. Round you answer to t
Crank
Present Value of an annuity is given by the formular
PV = P(1 - (1 + r)^-n)/r; where PV = $28,000, r = 0.081/12 = 0.00675, n = 35 and P is the periodic (monthly) payment.

P = PVr/(1 - (1 + r)^-n) = (28,000 x 0.00675)/(1 - (1 + 0.00675)^-35) = 189/0.2098 = 900.90

Therefore, the monthly payment is $900.90

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.
ollegr [7]

Answer:

k=5

Step-by-step explanation:

step 1

Find the equation of the line f(x)

we have the points

(-4,0) and (-2,2)

<em>Find the slope m</em>

m=(2-0)/(-2+4)\\m=1

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=1\\(-4,0)

substitute

y-0=(1)(x+4)

y=x+4)

Remember that

f(x)=y

so

f(x)=x+4

step 2

Find the equation of the line g(x)

we have the points

(-4,0) and (-2,-10)

<em>Find the slope m</em>

m=(10-0)/(-2+4)\\m=5

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=5\\(-4,0)

substitute

y-0=(5)(x+4)

y=5(x+4)

Remember that

g(x)=y

so

g(x)=5(x+4)

Remember that

g(x)=kf(x) ------> g(x)=5(x+4)

therefore

k=5

1. Solve the following<br> system:<br> 2x + 2y = 38<br> y = x + 3
pashok25 [27]

Answer:

y=11

x=8

Step-by-step explanation:

This is Elimination

2x+2y=38

Subtract 2x on both sides   2y=-2x+38

Then Multiply 2(y=x+3)  which equals 2y=2x+6

Solve by Elimination

2y=-2x+38

2y=2x+6

add the y's and since the x's are different those cancel out, then add 38 and 6.

then you do the equation 4y=44

divide both by 4

y=11

then you do 11=x+3

subtract 3 on both sides

x=8

and there you go

I hope this is how you wanted it solved
