Answer: A) (x + 3)^2 + 6

Step-by-step explanation:

x^2 + 6x + 15

Subtract 15 from both sides of the equation.

x^2 + 6x = -15

Complete the equation and add to both sides. Since (6 = 3 + 3), (3 x 3 = 9)

x^2 + 6x + 9 = -15 + 9

Simplify

(x + 3)^2 = -6

Add 6 to both sides of the equation

(x + 3)^2 + 6

Find the ordered pairs that solve the equation y=12

Rufina [12.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

y = 0.5x

when x = 12

y = 0.5 · (12)

y = 6

when x = 0

y = 0.5(0)

y = 0

when x = 8

y = 0.5(8)

y = 4

when x = 12

y = 0.5(12)

y = 6

Thus, the table is completed such as:

x y

0 0

8 4

12 6

Therefore, the ordered pairs that complete the equation y = 0.5 x are:

(0, 0)

(8, 4)

(12, 6)

The graph of the equation is attached below.

A toy rocket is launched straight up from the top of a building. The function that models the height as a function of time is h(

kicyunya [14]

Answer: 50 ft

Step-by-step explanation:

The correct function is h(t)=-16t^2+200t+50.

Hi, to answer this question we simply have to replace t =0 in the function given:

h(t)=-16t^2+200t+50.

h (0) = -16t^2+200t+50.

h(0) = 50

When the time is 0, the rocket is at the top of the building.

The rocket was launched from a 50 ft height.
