Answer:
1/3 and 5/7. that's number one I think
Answer:
2
Step-by-step explanation:
when it returns to the ground , h = 0
32t -16t2 = 0 and solve for t
t = 0, 2 ....0 is the start, 2 is when it returns
Answer:
y=-2
Step-by-step explanation:
Let f(x)= -4x+7 and g(x)= 10x-6. Find f(g(x)).
<em>FYI: f(g(x)) can also be written as (f</em><span><em>○g)(x).
</em>What this really means is to take x and put it through g, then through f.
Since we don't have a specific value for g, we can just put that x value through f,
<em>
</em>g(x) = 10x-6
f(x) = -4x+7
f(g(x)) = -4(g(x))+7
f(g(x)) = -4(10x-6)+7
f(g(x)) = -40x+24+7
f(g(x)) = -40x+31<em>

To do this you have to fill in the equation
![base*height=area](https://tex.z-dn.net/?f=base%2Aheight%3Darea)
, but you don't know the height, so we'll use
![h](https://tex.z-dn.net/?f=h)
for height. Plugging in the numbers you gave me, the equation is:
![8*h=30](https://tex.z-dn.net/?f=8%2Ah%3D30)
. To solve this, we need to find
![h](https://tex.z-dn.net/?f=h)
. To find height you do
![\frac{area}{base}](https://tex.z-dn.net/?f=%20%5Cfrac%7Barea%7D%7Bbase%7D%20)
. Doing this, we get
![h](https://tex.z-dn.net/?f=h)
