Answer:
See below in bold.
Step-by-step explanation:
a) h = -3t^2 + 15t = 0
-3t(t - 5) = 0
t = 0, 5 are the zeroes of the relation.
b) The ball hits the ground when h = 0 so it is after 5 seconds.
c) The path of the ball is a parabola which opens downwards so the maximum height is when x = 5/2 = at 2.5 seconds.
d) this maximum height is -3(2.5)^2 + 15(2.5) = 18.75 meters.
3 3/8 + 6 2/5 + 3 7/8 + 4 5/8 = 731/40 and simplify that and u get 18 11/40.
The options are given in factored form.
If a function is zero at x=3, this means x=3 is a root of the equation. x = 3 can also be written as x - 3 = 0
So, if x = 3 is a root of the equation, x - 3 will be a factor of the function. From the given options we can see only Option C contains x - 3 as its factor. Substitute x = 3 in option C and the function value will be zero.
So, the correct answer is option C
Using the volume of a sphere, the total volume of air inside six of Jake's basketballs is of 2140.8 cubic inches.
<h3>What is the volume of a sphere?</h3>
The volume of a sphere of radius r is given as follows:
From the problem, since the properly inflated basketball measures 8.8 inches across, the diameter is of 8.8 inches, hence the radius is:
r = 8.8/2 = 4.4 inches.
Then the volume in cubic inches of a single ball is:
V = 4 x pi x (4.4)³/3 = 2140.8 cubic inches.
For the six balls:
6 x 356.8 = 2140.8 cubic inches.
