Answer:

67.5 sq. ft

Step-by-step explanation:

15 ft is the base, and 9 is the length of one side, if you multiply the two together, you get 135 sq. ft; however, this is just the length of a rectangle twice the size of the triangle, to get the area of the triangle you'll need to divide 135 by 2 which is 67.5 sq. ft.

A man buys a car for $33,000 with no money down. He pays for the car in 48 equal monthly payments with interest at 9% per annum,

Crazy boy [7]

Answer:

Man has to pay $1921.19 per month.

Step-by-step explanation:

The formula of Compound Interest is:

$A = P(1+\frac{r}{n})^{nt}$

where A = Amount

P = Principle

r = rate

n = Number of Compounding per year

t = total number of year

Here, A = 33,000, r = 9% = 0.09, n = 12(monthly), and t = 48(48 months).

Putting all these values in above formula:

$33000 = P(1+\frac{0.09}{12})^{12\times4}$

⇒ $33000 = P(\frac{12.09}{12})^{48}$

⇒ $33000 = P(1.0075)^{48}$

⇒ $33000 = P(1.4314)}$

⇒ P = 33000 ÷ 1.4314 = 23054.35

Monthly payment = 23054.35 ÷ 12 = 1921.19

Hence, Man has to pay $1921.19 per month.

What is an equation of the line that is parallel to y=3x-8 and passes through point (4,-5)?

kompoz [17]

The equation of the line that is // to the given equation MUST HAVE THE SAME SLOPE.

The slope of the hiven equation is the number next to x or 3.

See it?

We know the slope is 3 and one point is given.

We now use the point-slope formula to find the equation.

y - y_1 = m(x - x_1)

See picture. The answer is y = 3x - 7.
