Answer:
The ball reaches 44 ft above the ground after 4 sec.
Step-by-step explanation:
Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t. Indicate exponentiation with " ^ "
-16t^2 + 300 = 44 becomes
-16t^2 + 256 = 0, or 16t^2 = 256. Then, taking the square root of both sides, we get:
4t = 16, or t = 4 sec. The ball reaches 44 ft above the ground after 4 sec.
Answer:
- 5
Step-by-step explanation:
The opposite of 7c is the negative of 7c, that is - 7c
Thus the sum of 7c - 5 and the opposite of 7c is
7c - 5 + (- 7c) = 7c - 5 - 7c = - 5
Answer:
90 degree
Step-by-step explanation:
Let represent the measure of the third angle. Then, − can represent the measure of the second angle. The
sum of the two angles in the right triangle will be °.
− + =
− =
− + = +
=
=
=
The third angle is and therefore measures °. Replacing with in − gives () − = − = .
Therefore, the measure of the second angle is °. The measure of the third angle is °.
Answer:
Period = 
Step-by-step explanation:
The period of the function is the interval of x-values which represents the length of one cycle.
Another meaning The period of the function is the length between two similar points such as the length between two peaks of the function.
AS shown on the graph, the function has peak equal to 3 and repeated every (π/2)
So, the period of the function f(x) shown in the graph =
