Please use " ^ " to indicate exponentiation:  <span>y=−0.5x^2+8x 

Examining this function, we see that its graph is a vertical parabola opening down.

You did not supply instructions for this problem.
However, one could guess that you might want to find the highest point of the grasshopper's path.  To do this, find the vertex:  Find the x value defined by 

x = -b/(2a).  Here, a= -0.5 and b= 8.  Thus, the vertex is at x = -8/(2[-0.5]), or 

x -8/(-1) = 8 units.  The corresponding y value is then 

y =  </span><span>−0.5*8^2+8(8)  = -0.5(64) + 64, or 32 units.</span>

Which box plot represents a set of data that has the greatest mean absolute deviation? (see attached image)
insens350 [35]

Answer:

#1

Step-by-step explanation:

Because To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

An official NHL hockey puck is shaped like a cylinder with a diameter of 3 inches and a volume of 7.1 cubic inches. What is the
Dima020 [189]

H=1in

You would need to use the equation V= pie times radius squared times height. Since it gives you the diameter, you would need to divide 3 by 2 to get 1.5. So now you would plug in 7.1=pie×1.5(squared)×h

Now solve the equation to get 1in.

And you can check this answer by using this same equation to plug in pi×1.5 (squared)×1 and you will get 7.1 as your volume.

ILL GIVE BRAINLIST ON WHOEVER GETS RIGHT!!!!!!!
Korvikt [17]

Answer:

hey,its option a

Step-by-step explanation:

because angle F= angle M and angle G= angle L

and angle H= angle N

To know third angle in ∆HGF

,we know sum of all angles in a triangle is 180°

______________________________

let angle H be unknown value x

x+51+36=180

x=180-87 ---------------- 1

similarly in ∆MNL

let angle be y

51+36+y=180

y=180-87----------------2

_______________________________

From 1&2 we observe qngle x= angle y

Solve for x. Round your answer to the nearest thousandth.
pogonyaev

Answer:

7.08

Choice A

Step-by-step explanation:

From the right-angled triangle we have been given the following;

One angle - 33 degrees

The hypotenuse - 13 units

We are required to determine the length of the side, opposite the angle, marked x.

Using the Mnemonic; SOHCAHTOA

The sine of an angle is; (opposite side)/(hypotenuse)

Therefore;

sin 33 = x/13

x = 13 * sin 33

x = 7.080
