At 1 second, the toy rocket, $R\left(t\right)$  , is above the drone,  $D\left(t\right)$  .  In function notation this would be:

•  $R\left(1\right)=D\left(1\right)$  

•  $R\left(1\right)<D\left(1\right)$  

•  $R\left(1\right)>D\left(1\right)$  

•  $R\left(t\right)=D\left(t\right)$

Sprinkles cupcakes sells cupcakes by the dozen. Sprinkles charges $12.95 for one dozen cupcakes and a charge of $0.50 per each additional topping.

• Y = 12.95X + 50

• Y = 50X + 1295

• Y = 12.95X + .50X

• Y = .50X + 12.95

The volume of a cube can be found using the function f(x) = x³ with x representing the length of one side. If the cube is cut in half, the function to find the volume changes to g(x) = 1/2 x³. A graph of f(x) and g(x) is shown below. The points represent the dimensions and volume of a cube and the dimensions and volume when the cube is cut in half.

Which of the following statements is NOT true?

• The side length of the cube is 2 units.

• The original volume of the cube is 8 cubic units.

• Point B represents the side length and volume of the original cube.

• The side length of the original cube was 2, but when cut in half the volume is 4 cubic units.
