Answer:

0.75, 1.25

Step-by-step explanation:

first we bring the line equation into the same format as the parabola equation (y = ...)

3x - y = 1

=>

y = 3x - 1

now we can say for the intersection points both equations must have the same result.

4x² - 1 = 3x - 1

4x² - 3x = 0

x(4x - 3) = 0

there are only 2 possible cases to make this true :

x = 0

and 4x - 3 = 0

4x = 3

x = 3/4 = 0.75

for the y value let's use the easier equation (line) :

y = 3×3/4 - 1 = 9/4 - 4/4 = 5/4 = 1.25

ruslelena [56]

Answer: The company must sold 382 units to break even.

Step-by-step explanation:

Hi, there is no question asked, so I suppose that  you need to  find the number of items (x) to break even.

To answer this question we have to equal both sides of the equations:

Since costs equal its income:

C=R

So:

38x +19100= 88x

Solving for x

19100= 88x-38x

19100=50x

19100/50 =x

382=x

The company must sold 382 units to break even.

Feel free to ask for more if needed or if you did not understand something.

Answer:

  51.7°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Tan = Opposite/Adjacent

  tan(D) = EF/FD = 95/75

  D = arctan(95/75)

  ∠D ≈ 51.7°
