The distance between the points is 10.4
1. To find the vertex of a parabolla whose equation is written in the standard form, you must apply the following proccedure:
2. You have:
y=-0.18x²+4.4x-12
a=-0.18
b=4.4
3. You must apply the following formula:
<span>
x=-b/2a
x=-4.4/2(-0.18)
x=-4.4/-0.36
x=12.22
4. When you susbtitute x=12.22 into the equation </span>y=-0.18x²+4.4x-12, you obtain:
y=-0.18x²+4.4x-12
y=-0.18(12.22)²<span>+4.4(12.22)-12
</span> y=14.88 feet
5. The answer is: The maximum height of the tunnel is <span>14.88 feet</span>
I think the answer is 6.6
The volume of a cube can be expressed as
Let V = volume
Let a = side length
V = a^3
We need to solve the formula to isolate the variable a. First, we must cube root each side.
∛(V) = a. With our new formula, we plug in 64 cube inches into V.
∛(64) = a.
4 = a.
The length of one side on our cube is 4 inches.
