Write 9^0 , 9^3, and 9^-2 in order least to greatest

The order is 9^-2, 9^0, 9^3.

When an exponent is negative, the term can be moved from the numinator to the denominator (or vise versa) to change the negative exponent to a positive one. So 9^-2 becomes 1/9^2 = 1/81.

Anything to the 0th power becomes 1. So 9^0 is 1.

Finally, 9^3 is 729.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
