Answer:

Step-by-step explanation:

2.5doz(12/doz)=30 eggs. So revenue minus cost when selling them for $2 each is

2(30)-45=15

Since 15 is positive he made a profit of $15 dollars.

What is the function? F(x)=2x^2-3x+1
olasank [31]

Answer:

To satisfy the hypotheses of the Mean Value Theorem a function must be continuous in the closed interval and differentiable in the open interval.

Step-by-step explanation:

As f(x)=2x3−3x+1 is a polynomial, it is continuous and has continuous derivatives of all orders for all real x, so it certainly satisfies the hypotheses of the theorem.

To find the value of c, calculate the derivative of f(x) and state the equality of the Mean Value Theorem:

dfdx=4x−3

f(b)−f(a)b−a=f'(c)

f(x)x=0=1

f(x)x=2=3

Hence:

3−12=4c−3

and c=1.

Use the Angle Addition Postulate to find the measure of each angle.
Simora [160]
For number 15 and 16, you just have to find the absolute difference between the two points along the calibration of the protractor.

15. ∠BXC = |B - C| = |140° - 110°| = 30°
16. ∠BXE = |B - E| = |140° - 30°| = 110°

For numbers 20 and 21, apply the Angle Addition Postulate. This is when you add the individual interior angles to equate to the total angle.

20. ∠PQS = ∠PQR + ∠RQS
      112° = 72°+ 10x°
       x = 4

21. ∠KLM = ∠KLN + ∠NLM
      135° = 47°+ 16y°
       y = 5.5

[|] Explanation [|]

<em>Exterior Angles:</em>

<u><em>Angles facing outward on a triangle</em></u>

Angles 6, 5 and

4 are not inside the main triangle. They are wide open. <u><em>Exterior simply means the outside of something.</em></u> Angles 6, 5 and 4 are the outside angles to the main triangle.
