Answer:

29.787%

Step-by-step explanation:

The computation of the percentage that spend on yellow pages is shown below:

= Yellow pages ÷ Total advertising cost

= $700 ÷ ($700 + $600 + $650 + $400)

= $700 ÷ $2,350

= 29.787%

a manufacturer is designing a flashlight for the flashlight to admit a focused beam the bull needs to be on the central axis of

Helen [10]

Answer:

y= 1/12(x-0)^2+0

this answer works as an upward parabola

Step-by-step explanation:

The formula for a veritcal parabola is y=1/4p(x-h)^2+k
(h,k)= coordinates of the vertex of the parabola
p= absolute value of the distance from the vertex to the focus/directrix
In this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex.
Now, you know the values of the variables. Fill in the values
FROM THE FORMULA: 1/4p turns into 1/12 since p is 3.
(x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0
once all the variables are given values (except x and y) you have made your equation!
The answer is y=1/12(x-0)^2+0

MARK BRAINLIEST! this took forever, and I know this is the right answer since I got a perfect grade when I turned mine in.

Evaluate functions from their graph g(−9)= See the Correct Answer Attached!

r-ruslan [8.4K]

Evaluating the function from the given graph, g(-9) = 1.

<h3>How to Evaluate a Function?</h3>

To find the value of a function for a given x-value using a given graph, trace the x-value against the corresponding y-value on the y-axis.

To evaluate the function from the graph given, for g(-9), find the y-value that corresponds to the x-value of -9.

The graph shows that when x = -9, the corresponding y-value is 1.

Therefore, g(-9) = 1.

PLEASE HELP!!! Solve for y.

ivolga24 [154]

- 2.1 = y/6 + 17.1
- 2.1 - 17.1 = y/6
- 19.2 = y/6
19.2*6 = y
-115.2 = y

So y = - 115.2.

Hope this helps ! This "/" is a fraction.
