Answer:
false
Step-by-step explanation:
Here, Function: h(t)= -16t² + 70t + 40
So, put the value of t, (time at which you want to calculate the height)
h(1) = -16(1)² + 70(1) + 40
h(1) = -16 + 110
h(1) = 94
Now, h(2) = -16(2)² + 70(2) + 40
h(2) = -64 + 180
h(2) = 116
h(3) = -16(3)² + 70(3) + 40
h(3) = -144 + 250
h(3) = 106
In short, Your height depends on time, and at each time it would be different, can be expressed by the coordinates on a Graph: (1, 94) (2, 116) (3, 106)
Hope this helps!
Answer:
7
Step-by-step explanation:
7 is a common positive factor if 14 and 21. 2:3
Your question has been heard loud and clear.
Alright , so basically , the area of a circle formula = pi * R squared
R = radius = 4 units
Pi = 3.14
So , Area = 3.14 into 4 = 12.56 units
So Area of the circle = 12.56 units
Thank you
