Answer:
t = 2.25 seconds
Step-by-step explanation:
Let
x ----> the time in seconds that the ball traveled
H(t) ---> the height of the ball in feet
we have
we know that
When the ball hit the ground, the height of the ball is equal to zero
so
To find out the time the ball traveled, equate the function H(t) to zero
For H(t)=0
solve for t
Factor -16t
The solutions are
Answer:
The volume of the solid is 420m³
Step-by-step explanation:
The area of any pyramid is "1/3 · B · h", where B is the area of the base, and h is the height.
Knowing this we just need to solve for a couple of things.
First, and the easiest is the height of the triangle which (thankfully) is given to us. The height is 15m, which plus one number into our equation.
1/3 · B · 15
Second, we need to find the area of the base of the pyramid. That's done easily by finding the area of a triangle ( →
→
→
) giving us 84 units. This puts another number into our equation.
1/3 · 84 · 15
Now that we have all of the parts to our equation, we can solve it.
1/3 · 84 · 15
1/3 · 1260
420
The volume of the solid is 420m³
Answer:
The value of A is 1, D is 0, E is -2 and F is 0.
Step-by-step explanation:
The given equation is
...(1)
The standard form of the circle is
Where, (h,k) is the center of the circle and r is the radius.
It can be written as
....(2)
On comparing (1) and (2) we get.
Therefore the value of A is 1, D is 0, E is -2 and F is 0.
