The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. F
Otrada [13]

Answer:

Surface area: 500

Volume: 5500

Step-by-step explanation:

Scale factor: 2:5

This means that the dimensions of the larger figure are 5/2 of those in the smaller figure.

Surface area:

The surface area is found multiplying the square of the change(5/2) by the original surface area(80). So

S = (\frac{5}{2})^2 \times 80 = \frac{25}{4} \times 80 = 25 \times 20 = 500

Volume:

The volume is found multiplying the cube of the change(5/2) by the original volume(352). So

S = (\frac{5}{2})^3 \times 352= \frac{125}{8} \times 352 = 125 \times 44 = 5500

Does this graph represent a function
Hunter-Best [27]

Answer:

Step-by-step explanation:

The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.
