Answer:

135

Step-by-step explanation:

Ratio = 3 : 9

Angles are : 3x , 9x

3x + 9x = 180 {supplementary angles}

12x = 180 {divide both side by 12}

x = 180/12

x = 15

Larger angle = 9x = 9*15 = 135

N a soccer game, Sally kicks the ball to a teammate who is on the other side of the field. The ball's height h (in feet above th

tresset_1 [31]

Answer:

At the time that it is kicked, the ball is on the ground, that is, it's height is 0 feet.

Step-by-step explanation:

The height of the ball after t seconds is given by the following equation:

$h(t) = -2t^{2} + 10t$

What is the height of the ball at the time it is kicked?

The ball is kicked at t = 0.

So we have to find h(0)

$h(0) = -2*0^{2} + 10*0 = 0$

At the time that it is kicked, the ball is on the ground, that is, it's height is 0 feet.

Which range of time values describes the entire interval over which she would be interpolating

horsena [70]

Answer: first option 0 to 30 minutes.

Jusitification:

Interpolation is the prediction of an intermediate value using a linear model.

In this case, she has the data for 0, 5, 10, 15, and 30 minutes.

So, she can interpolate between any pair of consecutive data to find an intermediate value.

For example: i) if she wants the value for 20 minutes, she can interpolate between 15 and 30 minutes, ii) if she wants the value for 7 minutes, she can interpolate between 5 and 10 minutes, iii) if she wants the value for 12 mintues, she will interpolate between 10 and 15 minutes.
