I think 3 is 4) 3/4, not sure about 4 though sorry
Answer:
52.2
Step-by-step explanation:
Light reflects off a mirror at the same angle it hits it at (as shown in the image). Since both triangles are right triangles, we can say they are similar by AA similarity.
Since they're similar, we can write a proportion.
HT / TV = JS / SV
Plugging in values:
5.8 / 4 = JS / 36
JS = 52.2
The wall is 52.2 feet tall.
The given parabola will open; Down
<h3>How to interpret a parabola curve?</h3>
In parabolic curves, if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
Now, we are given the equation of the parabola s;
-36y = x²
divide both sides by -36 to get;
y = -x²/36
From the above it is clear that the leading coefficient is less than zero and as such the parabola will open in the downward direction.

Answer:
We get t= 7.22 and t=0.28
The correct options are Option A and Option G
Step-by-step explanation:
The height h of toy rocket at time t seconds after launch is given by the equation 
We need to find how many seconds until the rocket is 40 feet?
We are given height of rocket h(t) = 40 feet
and we need to find time t
Using the equation we can find time t
We have h(t)=40
Now, we will solve the quadratic equation using quadratic formula: 
We have a =16, b=-120 and c=32
Putting values and finding t
So, we get t= 7.22 and t=0.28
The correct options are Option A and Option G
