Answer:

A.  the times at which the golf ball is on the ground

Step-by-step explanation:

The expression of the function is

h(x)= -4x^2+36x

The roots can be seen in the image below

You have a formula which represents the height over time.

The roots of the equation indicate that the height is equal to zero

The correct option is

A.  the times at which the golf ball is on the ground

The ball is in the ground at x= 0 and x = 9 seconds

<em>∠PYG = 137°</em>

Step-by-step explanation:

We know that a straight line is equal to 180°, so by looking at the image we can tell that if we added both of these angles together they would be equal to the straight line.

We can make an equation by adding these two angles together and setting them equal to 180.

2p+153+6p+91=180

We can combine like terms.

8p+244=180

Subtract 244 from both sides.

8p=-64

Divide.

<em><u>p = -8</u></em>

Now that we have found what p is equal to, we can plug it in to find the measure of ∠PYG.

2*-8+153

<em><u>= 137</u></em>

~

If you wanted to double check this answer, we can plug in -8 for p on the other side and make sure both would be equal to 180.

Like this...

6*-8+91

= 43

And we know that...

137 + 43 = 180

~

So...

<u><em>∠PYG = 137°</em></u>

<u><em>∠HYG = 43°</em></u>

9. a. Maurice says that 1079 ÷ 62 is 16 with a remainder of 87. a. Without seeing his work, how can you tell Maurice divided inc
mamaluj [8]

Answer:

a.  We can tell that Maurice divided incorrectly because if the dividend is 62, you can't have a remainder of 87, because 62 goes into 87 once, so the answer would be 17 with a remainder of 25.  B. YOu can use that fact to find the correct quotient, because 87/62 is 1, with a remainder of 25, so 16+1=17, so the answer is 17 with a remainder of 25.   Please vote the brainliest.
