All are negative exponent property except for the top right one
Answer:
0.25
Step-by-step explanation:
Area of a triangle = 1/2 * b * h
b = base
h = height
We know:
h = x
b = 4x
Area = 338ft^2
Let's plug these numbers into the Area formula above.
338ft^2 = 1/2 * 4x * x
First, let's divide both sides by 1/2
676ft^2 = 4x * x
Let's simplify the right side.
676ft^2 = 4x^2
Take the sqrt of both sides.
26 = 2x
Divide each side by 2
13 = x
Remember, the height = x = 13 feet
Move the decimal two places to the right and add a % sign
Ex) .35 = 35%
Answer:
The vertex of the graph is (-1,0)
Step-by-step explanation:
A vertex has different definitions
It refers to the point where we have the axis of symmetry
It can also be the point at which the graph changes direction
From the graph we have here, the vertex lie on the horizontal axis
It has an ordered pair value of (-1,0)
