Answer:
56.25 feet.
Step-by-step explanation:
h(t) = 60t - 16t^2
Differentiating to find the velocity:
v(t) = 60 -32t
This equals zero when the ball reaches its maximum height, so
60-32t = 0
t = 60/32 = 1.875 seconds
So the maximum height is h(1.875)
= 60* 1.875 - 16(1.875)^2
= 56.25 feet.
<h3>
Answer: 4900 (choice D)</h3>
===================================================
Work Shown:
1 km = 1000 m
3.5 km = 3500 m ............. multiplying both sides by 3.5
(70 paces)/(50 m) = (x paces)/(3500 m)
70/50 = x/3500
7/5 = x/3500
7*3500 = 5x .............. cross multiply
5x = 7*3500
x = (7*3500)/5
x = (7*5*700)/5
x = 7*700
x = 4900
Ann takes 4900 paces to walk 3.5 km
The circumference of a circle is found by using the equation: C= 2 x PI x r
Both circles have r = 1
Circumference = 2x 3.14 x 1 = 6.28.
Diameter is 2 times the radius= 2x1= 2
The ratio of the circumference to the diameter = 6.28 / 2 = 3.14 which is the value of PI
Answer:
Reduce
Step-by-step explanation:
0.75 would be making the subject smaller because it is less than one.
