Answer:

Range tells you how high and low the graph of this parabola goes in the “y” (vertical) directions.

1. We can see that the parabola peaks on the y-axis at y = 4. That’s as HIGH as it goes.

2. We also see that both sides of the parabola descend to the level of y = -7. That’s as LOW as it is shown to go.

So putting these together, we say the Range is given by:

-7 <= y <= 3

AMBIGUITY WARNING:

Because the two branches of the parabola go fall right down to the edge of the picture boundary, it’s UNCLEAR whether the parabola truly stops at y = -7 or CONTINUES on (to negative infinity).

In THAT case, the RANGE simplifies to:

Y <= 4

Done.

A rectangle and regular hexagon are shown below. Find the value of x that makes the polygons above have the same perimeter

pav-90 [236]

The answer is x=3
because 3x2 is 6 and 6x6 is 36 because a hexagon has 6 sides, and 3x3 is 9+3 is 12 and 12+12 is 24 and 3+3 is 6 so 6+6 is 12 and is you add that to 24 then that’s 36 aswell.

What is the slope for the function y=2x^2+2 at the point x= 3?

Katarina [22]

1) We have to calculate the first derivative:
y=2x²+2
y´=4x

2) the slope at the point x=3; will be f´(3);
f´(3)=4(3)=12

answer: the slope will be 12.

In Virginia, the Grand Caverns is approximately 35 kilometers from the Frontier Culture Museum. You make a drawing of the two lo

loris [4]

Answer:

We will draw the locations at a distance of 6 inches apart.

Step-by-step explanation:

We are given that,

Distance between Grand Caverns and Culture Museum = 35 kilometers

Now, we are drawing the two locations with a scale of 6 inches representing the distance 35 kilometers.

It is required to find the distance we will draw the locations.

As, we have that,

<em>The 6 inches scale represents the 35 kilometer distance between the locations.</em>

Thus, we will draw the locations at a distance of 6 inches apart.
