80x 40 x 20 feet is your answer! Hope this helps
Part A
We have
. To solve for the x-intercept, we set f(x) equal to 0. That is
Take the square root of both sides,
The x-intercept is (-2,0).
To solve for the y-intercept, we set x=0. That is
The y-intercept is (0, 8)
The coordinates of the optimum point are actually the vertex which can be easily seen from the vertex form equation given above. The minimum point is
(-3, -1).
Part B.
We have
.
Factor out -2
Complete the square
Simplify
Part C
We have
.
The maximum height is 12.25 feet after 0.875 seconds from the time of the jump. The dolphin will be back in the water after 1.75 seconds. The graph of the jump is shown in the photo.
Answer:
B
Step-by-step explanation:
If the figure is regular, then everyone of the central angles are equal. They add up to 360 degrees.
x + x + x + x + x + x + x = 360 Combine
7x = 360 Divide by 7
x = 360/7
x = 51.43
