By using the motion equations, we conclude that she will make the goal.

<h3>Will she make the goal?</h3>

First, we know that the goal is 20ft away, and the position in x is given by:

x = 28*cos(58)*t

Let's find the time in which the ball will travel these 20 ft.

20 =  28*cos(58)*t

(20)/(28*cos(58)) = t = 1.35

So the horizontal distance is covered in 1.35 seconds, now let's see which is the height of the ball at that time.

The height equation is:

y = -16*t^2 +28*sin(58)*t

Evaluating in t = 1.35 we get:

y = -16*(1.35)^2 +28*sin(58)*1.35\\\\y = 2.9

And the goal is 5ft tall, so we can conclude that she will make the goal.

Can somebody help me with this? I'm bad at this stuff &lt;.
Sladkaya [172]

Answer:

Prime numbers are whole numbers that has factors of 1 and itself.

Example: 2 is a prime because there is no way you could factor it except 1 and 2.

Composite numbers have more factors which also include 1 and itself.

Example: 50 is composite because it has factors more than 1 and itself.

5 is a factor of 50; 10 is a factor of 50.

So let's begin sorting.

<em>Prime: 7, 11, 31.</em>

Composite: 4, 8, 10, 27.

Hope this helps! :)

I believe the answer is 120. 3 5/6 turns into 3.833 when turned into a decimal. 3.833 would round up to 4 which is the nearest whole number. 34 3/7 would turn into 34.4285 as a decimal which turns into 30 when rounded to the nearest ten.
