The statement which is true is the airplane reaches its maximum height of 81 feet in 12 seconds.
Since the height of the plane is a function given by a parabola, we need to know the equation of a parabola in vertex form
<h3>What is the equation of a parabola in vertex form?</h3>
The equation of a parabola with vertex (h,k) is given by y = a(x - h) + k
Since the height (in feet) of the airplane as a function of time (in seconds after the timer was started) is given by the equation h(t) = −(t − 12) + 81
- Since this is the equation of a parabola in vertex form, comparing h with y, we have that a = -1, h = 12 and k = 81
- Since a = -1 < 0 this implies that the point (h, k) = (12, 81) is a maximum point
So, the statement which is true is the airplane reaches its maximum height of 81 feet in 12 seconds.

Given :
There are 50 people at the city swim park today. Everyone in the park was wearing swim suits or sunglasses, some people had both.
38 have swim suits on and 25 have sunglasses.
To Find :
How many people had swim suits on but not sunglasses.
Solution :
Let, A refer swim suits and B refer sunglasses.
∞∪∩
A ∪ B = 50
A = 38
B = 25
We need to find, A - (A ∩ B) .
We know,
(A ∩ B) = A + B - (A ∪ B)
(A ∩ B) = 38 + 25 - 50
(A ∩ B) = 13
So, A - (A ∩ B) = 38 - 13 = 25
Therefore, number of people with swim suits on but not sunglasses are 25.
Answer:
Step-by-step explanation:
Triangle area = 1/2*12*5
= 6*5
= 30
Circle = pi* radius²
= 3.14 * 2.5²
= 19.625
add 19.625+ 30
49.625
Answer:
12 bounce
Step-by-step explanation:
Let :
Number of Menard's bounce = x
Ben's bounce = x + 8
Diego's bounce = 2x
If Diego's bounce = 8
Then ;
2x = 8
x = 8/2
x = 4
Ben's bounce = x + 8
Ben's bounce = 4 + 8 = 12
