Answer:

9 pi yards squared

Step-by-step explanation:

By definition, the circumference of a circle is equal to 2pi(radius) or pi(diameter).

Since the circumference is 6 pi yards, we can work backwards to find the area.

Set the equation of the circumference of a circle and the circumference given to you equal to each other in order to find your radius. With the radius we can calculate your area.

2pi(radius)=6 pi yards

Divide both sides by 2

pi(radius)=3 pi yards

Divide both sides by pi

radius=3 yards

Now that we know the radius we can find the area.

By definition, the area of a circle is pi(radius)^2 (This reads as pi times the radius squared)

Squaring the radius is just multiplying it by itself. In this case you would multiply 3 by 3 to get 9.

pi(9 yards squared)=Area

Area=9 pi yards squared

Answer:

19,167

Step-by-step explanation:

Laura purchased a new vehicle for 27,382

She made a down payment of 30%

27,382×30/100

= 27,382×0.3

= 8,214.6

27382-8214.6

= 19,167

Hence Laura financed 19,167

Quickly please im very confused

deff fn [24]

Answer:

A: -16/3

B: 16/3

C: -6

D: -6

E: 6

Step-by-step explanation:

A would be -16/3 because you multiply -2 time 8 which is 116. And the denominator is 3.

B would be 16/3. It is the same as problem A but there are two negatives which make positive.

C is -6. You just divide -18/3.

D is the exact same as C. It just has parenthesis but the answer is still -6.

E is 6 because there are two negatives which make a positive.

When the domain of a function has an infinite number of values, the range always has an infinite number of values. True or false

iragen [17]

Answer:

Thus, the statement is False!

Step-by-step explanation:

When the domain of a function has an infinite number of values, the range may not always have an infinite number of values.

For example:

Considering a function

$f(x) = 5$

Its domain is the set of all real numbers because it has an infinite number of possible domain values.

But, its range is a single number which is 5. Because the range of a constant function is a constant number.

Therefore, the statement ''When the domain of a function has an infinite number of values, the range always has an infinite number of values'' is FALSE.

Thus, the statement is False!
