Which of the following is a valid comparison between the possible minimum and maximum values of the function y = -x2 + 4x - 8 an

Arturiano [62]

Answer:

The maximum value of the equation is 1 less than the maximum value of the graph

Step-by-step explanation:

We have the equation $y=-x^2+4x-8$ .

We can know that this graph will have a maximum value as this is a negative parabola.

In order to find the maximum value, we can use the equation $x=\frac{-b}{2a}$

In our given equation:

a=-1

b=4

c=-8

Now we can plug in these values to the equation

$x=\frac{-4}{-2} \\\\x=2$

Now we can plug the x value where the maximum occurs to find the max value of the equation

$y=-(2)^2+4(2)-8\\\\y=-4+8-8\\\\y=-4$

This means that the maximum of this equation is -4.

The maximum of the graph is shown to be -3

This means that the maximum value of the equation is 1 less than the maximum value of the graph

Find the diameter of the object.<br> 2 in.<br> diameter:

Softa [21]

Answer:

4 inches

Step-by-step explanation:

The radius is the line from the center of the circle to the edge. We can assume the black line on the orange is the radius.

We want to find the diameter. The diameter is twice the radius, or

d=2r

We know the radius is 2, so we can substitute that in for r

d=2*2

Multiply

d=4

So, the diameter is 4 inches
