Answer:
22.5 = x
Step-by-step explanation:
I'm using Pythagorean theorem.
A^2+B^2=C^2
18^2+13.5^2=C^2
324+ 182.25=C^2
506.25=C^2 ( now square root both sides)
22.5=c
The height of the ball according to the function h(t) is 16 feet after 1.92 seconds and after 0.46 seconds.
A function is defined as a expression containing one or more variables.
Technically speaking, a function is a means of linking a set of inputs to a set of outputs.
The height of the ball at any time t is given by the function:
Now the required height of the ball(in feet) is 16 feet. We have to find the value of t for which h(t)=16.
Let us substitute the values:
This is in the form of a quadratic equation in t.
Solving by using the quadratic formula:
We know that for a quadratic equation
Therefore for the above quadratic equation:
Therefore the ball reaches the height of 16 feet at times 1.92 seconds and at 0.46 seconds.

Answer:
Step-by-step explanation:
(3,2) (-2,5)
y2-y1/x2-x1
-2-5/3-2=-7/1
=-7
(2.5)^2 + (16.5)^2 = c^2
c = sqrt(2.5^2 + 16.5^2)
c = sqrt(278.5)
c = 16.69
Rounded up it would be 17, so the answer is D.
