Answer:
C=2πr
Step-by-step explanation:
The circumference is the total distance around the circle.
C=πd but d = 2r.
:.C=2πr.
ANSWER
False
EXPLANATION
The tangent function has no amplitude because it is not bounded.
The given tangent function is

This is of the form
f(t)=a tan(bt)
The period is given by


The first statement is true but the second is false.
Hence the whole statement is false.
Answer:
36 feet.
Step-by-step explanation:
We have been given that a ball is thrown upward from ground level. Its height h, in feet, above the ground after t seconds is
. We are asked to find the maximum height of the ball.
We can see that our given equation is a downward opening parabola, so its maximum height will be the vertex of the parabola.
To find the maximum height of the ball, we need to find y-coordinate of vertex of parabola.
Let us find x-coordinate of parabola using formula
.



So, the x-coordinate of the parabola is
. Now, we will substitute
in our given equation to find y-coordinate of parabola.






Therefore, the maximum height of the ball is 36 feet.
Answer:
180=2x+ 24( angles opposite to equal sides)
156/2=x
x=78
