Which of the following shows a number as a product of prime numbers in exponential form? Choose all that apply.
A) 2^3 x 3 x 6
B) 2^3 x 3 x 5
C) 3^2 x 5 x 10
D) 3^2 x 5^2

  B) 2^3 x 3 x 5

  D) 3^2 x 5^2

Step-by-step explanation:

6 and 10 are composite numbers, not prime, so the answer choices containing those factors can be eliminated. The remaining choices are shown above.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
