Answer:

Step-by-step explanation:

Use the "vertical line test."  Draw a vertical line through each graph.  If the line intersects the graph in more than one place, the graph does NOT represent a function.  Only the graph in the upper, right-hand corner represents a function, as a vertical line intersects this graph in only one place.

2. A sphere has surface area 16π. Find the radius of the sphere.
KiRa [710]

Answer:

The answer to your question is: 2.29 units

Step-by-step explanation:

Data

Volume = 16π

radius = ?

Formula

V = \frac{4}{3}π r^{3}

Process

                         16 π =  \frac{4}{3}π r^{3}

                         \frac{16(3)}{4} = r^{3}

                         r³ = 12

                        r = 2.29

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 4(m∠Y) − 185°. Find m∠Y.
alexira [117]

Answer:

Step-by-step explanation:

so S and Y are complementary...that means when added, they equal 90 degrees.

S + Y = 90

S = 4Y - 185

4Y - 185 + Y = 90

5Y - 185 = 90

5Y = 90 + 185

5Y = 275

Y = 275 / 5

Y = 55 <===== angle Y is 55

S + Y = 90

S + 55 = 90

S = 90 - 55

S = 35
