Answer:
ok in my opinion I think it's B as long as you didn't pick the same answer multiple times for other questions
Answer:
The answer to your question is x = 1.5 Vertex = (1.5, 3.5)
Step-by-step explanation:
Data
Function
y = -2x² + 6x - 1
Process
1.- Find the canonical form of the equation
y = -2x² + 6x - 1
y + 1 = -2x² + 6x
y + 1 = -2(x² - 3x )
y + 1 - 18/4 = -2(x² - 3x + 3/2²)
y - 7/2 = -2(x - 3/2)²
2.- Find the vertex
(3/2, 7/2) = (1.5, 3.5)
3.- Find the axis of symmetry
The axis of symmetry is the "x" coordinate.
axis of symmetry = 1.5
Step-by-step explanation:
Based off the information given, it is hard to determine the height of the elephant, therefore we are going to go through with the information given with the car.
Car: 3 + x = 5
x=2
Elephant: 15 - 2 = 13
13 ft.
Answer
40
The formula to determine the area of the right triangle is a*b/2
First, let’s input the numbers into the formula.
16*5/2
Now we need to solve.
16*5= 80
80/2= 40
Therefore, the answer would be 40.
