Answer:

Choice C correct answer.

Step-by-step explanation:

From the question statement, we observe that

d=6 in

r=d/2

so, r=6/2=3 in

The formula to find area is

A = πr²

Putting the value of radius, we get

A = π(3)²

A= 9π in²

This isn't hard at all! The 6 dolls she brought are 20% of her entire collection, right? All you have to do is multiply the 20% by 5 so you can get the amount of dolls to 100%, so

6 x 5 = 30

That's how many dolls there should be.

Find H.C.F. and L.C.M. of x3-y3, x2-y2 and (x-y) ?

maks197457 [2]

Answer:

1) x³-y³ = (x-y)(x²-xy+y²)

2)x²-y² =(x-y)(x+y)

3)x-y = (x-y)

hcf = (x-y)

lcm = (x-y)(x²-xy+y²)(x+y)= (x³-y³)(x+y)

Which set of ordered pairs could be generated by an exponential function?

devlian [24]

<u>ANSWER</u>

(0, 1), (1, 3), (2, 9), (3, 27)

<u>EXPLANATION</u>

The first and third options are completely out because the y-value of an exponential function is never zero.

For the second option the y-values has no geometric pattern or common ratio.

For the last option, we can observe the following pattern

$1 = {3}^{0}$

${3}^{1} = 3$

${3}^{2} = 9$

${3}^{3} = 27$

${3}^{x} = y$

The correct choice is the last option
