Which of the following equation represents a linear function 1. y = 20(0.3)^x
2. Y = 30x^2
3. Y = 2x + 5
4. Y = 2x + 5

4. Y = 2x + 5

Step-by-step explanation:

There's two of them, I just chose the last one

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

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
