I have to find the area of the shaded region in the figure above and answer using an exact and approximate answer

Answers

Answer:

3925 units²

Step-by-step explanation:

area of larger circle = πr² = (3.14)(250²) = 196,250

area of smaller circle = πr² = (3.14)(200²) = 125,600

area of full donut = 196,250 - 125,600 = 70,650

20/360 = 1/18 of full donut

1/18(70,650) = 3925 units²

Which is the equation of a line with a slope of -1 and a y-intercept of -6?
A y = -6x - 1
B y = -x - 6
C y = x - 5
D y = x + 6

Answers

I say A, because of it both being negative & having a y intercept .

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 1 and c = - 6 , then

y = - x - 6 → B

You want to buy a new car. You can afford payments of $300 per month and can borrow the money at an interest rate of 5.2% compounded monthly for 5 years.

Answers

Answer:

$367.17

Step-by-step explanation:

we are find the cost of the car after 5 years

Using the compound interest formula;

A = P(1+r/n)^nt

Given

Principal P = $300

rate r = 5.2% = 0.052

Time t = 5years

Time of compounding n = 1/12 (monthly)

Substitute into the formula

A = 300(1+0.052(12))^5(1/12)

A = 300(1+0.624)^0.4167

A = 300(1.624)^0.4167

A = 300(1.2239)

A = 367.17

hence the amount of the car after 5years is $367.17
