Equation :
This parabola is facing downwards and highest point of the parabola is it's vertex.
Highest point is (-2,2)
so the vertex is (-2,2)
The graph is passing through (-1,0)
Equation in vertex form is
Substitute back in Equation
the graph has two x intercepts -1 and -3
that means (x+1) and (x+3) are the factors
multiply factors to get the equation in standard form
-2x^2-8x-6=0
Answer:
<h2>1) y = 5</h2>
Step-by-step explanation:
x = 4 it's a vertical line.
Perpendicular line to a vertical line is a horizontal line.
A horizontal line has equation y = a.
A horizontal line passes through the point (3, 5) → x = 3 and y = 5.
Therefore the equation is y = 5
Answer:
The current intervals for the bins are too wide. Looking at the histogram, it is difficult to draw useful conclusions about the fuel efficiency of the trucks or to see the shape of the data distribution.

Here is the Plato answer
1 revolution is 2xPixr
it is 2xPixr=2x 3.14 x 15=94. 2cm
for 4 revolutions
it is 94. 2cmx4= <span>376.8 cm
the answer is C </span><span>: 376.8 cm</span>
