WILL GIVE BRAINLIEST IS ANSWERED FAST please! In the suspension bridge above, the two large cables connected to the two towers s

wing down in curves that are parabolas. Each tower rises 80 feet above the roadway, and the towers are 300 feet apart. At the center of the bridge, the two curved cables are 5 feet above the roadway. There are vertical cables that connect the roadway to these curved cables. The vertical cables are placed 15 feet apart. Vertical cables are not necessary at either of the towers. Suppose this bridge was damaged during a wind storm. Your job is to order new vertical cables to replace the ones between the two towers on the bridge.
Determine the number and length of each of the vertical cables needed between the two towers. Include the total feet of all the vertical cables added together. Enter your data in the table below. Round each length to the nearest hundredth of a foot.

10 Points! Drag the tiles to the correct boxes to complete the pairs.
Oksi-84 [34.3K]
<h2>Hello!</h2>

The answers are:

First box: 7 times the cube of the sum of x and 8

Second box: 8 added to the cube of 7x.

Third box: 8 added to 7 and x cubed.

Fourth box: the cube of the sum of 7x and 8.

<h2>Why?</h2>

We are given the expression and we need to macth to the correct verbal description, so we have:

First box:

7(x+8)x^{3}

It's 7 times the cube of the sum of x and 8

Second box:

(7x)^{3}+8

We have that "7x" is cubed and then, added to 8, so,  it's 8 added to the cube of 7x.

Third box:

7x^{3}+8

We have "7" times "x" cubed and added to 8, so it's 8 added to 7 and x cubed.

Fourth box:

(7x+8)x^{3}

We have "7x" added to 8, and the expression is cubed, so, it's the cube of the sum of 7x and 8.

Have a nice day!

What is the equation of the function that is graphed as line b?
alina1380 [7]

-- Look at the places where the line crosses the 'x' axis and the 'y' axis.
   Between those two points, it goes forward 2 units, but only rises 1 unit.
   So the slope of the line is  1/2 .

-- Look again at the point where the line crosses the y-axis.
   At that point, y=1 .
   That's the "y-intercept".

Now you have the slope and y-intercept of the line.

The equation of ANY straight line is

                         y = (slope)x + (y-intercept) .

You know what they both are, so you can easily write

                         y = 1/2 x + 1 .

Is that one of the choices ?
Yes it is.
Good enough for me.
That must be the correct one.

With no "blah blah blah" required.

What is the sum of a number and its additive inverse is equal to -1, 0 or 1?
MAXImum [283]
Additive inverse: In math the additive inverse of "a" is the number when added to "a" should give zero (a) + (-a) = 0

So the sum of a number and its additive inverse is always equal to zero
