Answer with Step-by-step explanation:
Since we have given that
Initial height = 3 feet
The baseball hits the ground after 2 seconds
t = 2 seconds
So, final velocity = v = 0
a. What was the initial velocity of the baseball?
Initial velocity is given by
b. What is the function that models the height, ℎ (in feet), of the baseball over a period of time tt (in seconds)?
As we know that the function of height would be
Here, 
is the initial height.
So, our function becomes,
c. At what time did the baseball reach its maximum height? What was the maximum height of the baseball?
Maximum height at time t:
Maximum height would be
The quotient is twice 405.5. Whenever dividing by .5 you multiply by 2 instead
C.)
Adam got the sum of his grades right, but he divided that correct figure by 6, getting 84 Before that division, the sum of his grades must have been 84 * 6, or 504. He should have divided 504 by 7, getting 72. Answer: His correct average test score is 72.
Answer:
Step-by-step explanation:
Begin
If this is a rhombus then <8 = 90 degrees as do all the central angles. That's because the diagonals intersect at right angles.
<4 = 38 z formation for parallel lines.
<7 = 52 The angles are part of a right angle triangle. <7 +38 = 90
<2 = 52 z formation of parallel lines (a rhombus has ll lines).
<3 = 38 The diagonals of a rhombus bisect each other.
<5 = 38 z formation for parallel lines.
<6 = 52 The diagonals of a rhombus are angle bisectors.
<1 = 52 The diagonals of a rhombus are angle bisectors.
Answer:
30
Step-by-step explanation:
All the degrees of a triangle should add up to 180 degrees.
D = F
D and F are not equal to 90.
If E = 30, D and F both equal 75.
75(2) + 30 = 180.
