Answer:

New = $18 383.51; used = $18 274.65

Step-by-step explanation:

The formula for the present value (PV) of a loan is

PV = (P/r)[1 - (1 + r)⁻ⁿ), where

P = the periodic payment

r = the interest rate per period

n = the number of payments

A. New car

Data:

P = $415

I = 3.99 % APR

n = 48

Calculation:

r = 3.99 %/12 = 0.0399/12 = 0.003 325

PV = (415/0.003 325)[1 - (1 + 0.003 325)⁻⁴⁸]

= 124 812.03(1 - 1.003 325⁻⁴⁸)

= 124 812.03 (1 - 0.852 710 44)

= 124 812.03 × 0.147 289 56

= $18 383.51

The maximum loan you can take out for a new car

is $18 353.81.

B. Used car

r = 4.29 %/12 = 0.0429/12 = 0.003 575

PV = (415/0.003 575)[1 - (1 + 0.003 575)⁻⁴⁸]

= 116 083.92(1 - 1.003 575⁻⁴⁸)

= 116 083.92 (1 - 0.82 576 82)

= 116 083.92 × 0.157 426 18

= $18 274.65

The maximum loan you can take out for a used car

is $18 274.65

Answer:

$\implies \dfrac{ -4x+7}{2(x-2) }$

Step-by-step explanation:

The given expression to us is ,

$\implies \dfrac{\frac{ 3}{x-1} -4 }{ 2 -\frac{2}{x-1}}$

Now take the LCM as ( x - 1 ) and Simplify , we have ,

$\implies \dfrac{\frac{ 3 -4(x-1) }{x-1} }{ \frac{2-2(2x-1)}{x-1}}$

Simplifying further , we get ,

$\implies \dfrac{ -4x+7}{2(x-2) }$

Hence the second option is correct .

Find the surface area of the composite figure.

ELEN [110]

Answer:

$644cm^2$

Step-by-step explanation:

First we'll work out the surface area of the pink figure.

That's the area of the two 5 by 6 rectangles on the top and bottom, plus the area of the two 5 by 20 and two 6 by 20 rectangles on the sides.

However, we note that the purple figure is blocking out a 6 by 12 section on the pink figure, so we'll need to subtract this.

The above works out to $2\times(30+100+120)-72=428 cm^2$ .

Then we'll work out the surface area of the purple figure.

This will be the area of the two 4 by 6 rectangles at the top and bottom, plus the area of the two 4 by 12 and one 6 by 12 rectangles on the sides. Note that there's only one 6 by 12 rectangle because the other face is joined to the pink figure, so it's blocked out.

That's $2\times(24+48)+72=216cm^2$ .

So the total surface area is $428+216=644cm^2$ .

Whats is the answer to this question below?

uysha [10]

Hey there. So first we need to know what the point slope form looks like.

It is Y-Y1=M (X-X1)

Knowing this you just plug in the given information.

M is equal to 1/6. So in this case all of the options have the correct m. Next we look at the Year value. We know Y is a positive 4. So the beginning of the equation is going to look like

Y+4=1/6 ( X-X1).

Nown plug in x. It would be a negative 5. Now your final answer would be option A. Hope the explanation helped.. :)
