Answer:
The ball remains in the air for 2.86 seconds.
Step-by-step explanation:
A baseball is hit into the air, and its height above the ground is described by the function
Where H(t) represents the height of the ball t seconds after it is hit.
The ball remains in the air before it hits the ground.
When the ball hits the ground,
So,
The equation may be solved using the quadratic formula.
Where
So,
Since the time cannot be negative, discard the negative value and accept the positive value
Therefore, the ball remains in the air for 2.86 seconds.
If a line is parallel to the x -axis, that means the formula is going to be y=a, y is going to be the same for all points.
We have the point where y coordinates = -2,
so the formula of the line y = -2.
Answer:
4488
Step-by-step explanation:
(24)(187)
Since the triangle will be a 30-60-90, because 360°/6 = 60° for each central angle, then that is bisected to find the height of each of the 6 equilateral triangles. This height is the same as the apothem.
In a 30-60-90 triangle, the sides are is the ratio of:
where x is opposite the 30° and 2x is opposite the 90°
Since the base is 10 and the hypotenuse is 10, 1/2 that is 5 (the x), and so:
So rounded up, you apothem then is closest to D) 9 in.
The slope is 1 it passes through the y axis one time
