Step-by-step explanation:
3 to the power of 5
3^5
= 3x3x3x3x3
= 243
The answer is (1,-4)
Remember that the vertex is the center of the parabola.
Answer:
y=-0.215x^2+35
Step by Step:
Let, 
, 
, 
, 
We know that, the general equation of the parabola.
Substitute the value of 
in equation 
and find the value of 
Hence, the equation of the parabola is:
Answer:
x=68
Step-by-step explanation:
We begin by setting up as a proportion. 99.2 and 112 ft are across from each other so we can put those as our numerators. Additionally 62 and (x+2) ft are across from each other so we can put those as denominators. Now we can set up our proportion and begin to cross multiply:
99.2/62 = 112/(x+2) is our equation. It might help you see it clearly to write it out as fractions. From here, we cross multiply.
When we do that, we get x=68
