What function can be used to model data pairs that have a common ratio?

linear
quadratic
exponential
none of the above

Option C. exponential

Step-by-step explanation:

"Common Ratio" is the term always used in geometric sequence which is in the exponential form.

We can write the function defined by exponential as

Where r is the common ratio and n is denoting number of terms.

Now if we plug in the values of n as 1, 2, 3, 4

The sequence will be and so on.

Therefore the exponential function can be used to model data pairs that have a common ratio.

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
