Answer:
0.125 seconds.
Step-by-step explanation:
We have been given that the height of a ball above the ground as a function of time is given by the function , where h is the height of the ball in feet and t is the time in seconds.
We can see that our given equation is a downward opening parabola as its leading coefficient is negative. The maximum point will be vertex of parabola.
To find the time, when the ball would be at its maximum height, we need to find the x-coordinate of vertex.
Using formula , we will find the x-coordinate of vertex of parabola as:
Therefore, the ball will be at a maximum height after 0.125 seconds.
Answer:
Step-by-step explanation:
we know that
In a right triangle
Applying the Pythagorean Theorem
where
c is the hypotenuse (the greater side)
a and b are the legs (perpendicular sides)
In this problem we have
substitute
Answer:
x=15
Step-by-step explanation:
3x=45
We want to get x by itself, so we divide each side by 3
3x/3 = 45/3
x =15
Answer:
7 + m = 4
Step-by-step explanation:
7 + m = 4
subtract 7 from both sides
and m= -3
