just plugin the x values into the equation to find f(x). Then use slope to find average rate of change

(36 +4)/(4+1) = 8

LenKa [72]

Answer:

lets say 4 is a and 2 is b.

Step-by-step explanation:

add a and b. find factors.

a = half of the 57.14 dollars

b = the other half

for the other 3 and 3 pizzas: 3x

3x is 3 cubed.

This case will give you 52 dollars % tax

What are the measures of Angles a, b, and c? Show your work and explain your answers.
andreev551 [17]
Answers: ∠a = 30° ; ∠b = 60° ; ∠c = 105<span>°.
</span>_____________________________________________
1) The measure of Angle a is 30°. (m∠a = 30°).
Proof:  All vertical angles are congruent, and we are shown in the diagram that angle A — AND the angle labeled with the measurement of 30°— are vertical angles. 

2) The measure of Angle b is 60°. (m∠b = 60<span>°).
Proof:  All three angles of a triangle add up to 90 degrees. In the diagram, we can examine the triangle formed by Angle A, Angle B, and a 90</span>° angle. This is a right triangle, and the angle with 90∠ degrees is indicated as such (with the "square" symbol).  So we know that one angle is 90°.  We also know that m∠a = 30°.  If there are three angles in a triangle, and all three angles must add up to 180°, and we know the measurements of two of the three angles, we can solve for the unknown measurement of the remaining angle, which in this case is: m∠b.  
 90° + 30° + m∠b = 180<span>° ;
</span>180° - (<span>90° + 30°) = m∠b ; 
</span>180° - (120°) = m∠b = 60<span>°
</span>___________________________
Now we need to solve for the measure of Angle c (<span>m∠c).
___________________________________________
All angles on a straight line (or straight "line segment") are called "supplementary angles" and  must add up to 180</span>°.  As shown, Angle c is on a "straight line".  The measurement of the remaining angle represented ("supplementary angle" to Angle c is 75° (shown on diagram).  As such, the measure of "Angle C" (m∠c) = m∠c = 180° - 75° = 105°.

Gas Use
Alisiya [41]
Answer: 10.75
Steps:
After 110miles, it used 2.75gallons
Therefore, the amount of gas used per mile is: 100/2.75= 40 gallon per mile

So after 430miles, the number of gallons used: 430/40 = 10.75 gallons

The Ivring Berlin Learning Center would like a possible net profit of $650,000 on its new resource manual it sells to schools. T
vazorg [7]

Answer:

Selling price should be $21 per unit.

Step-by-step explanation:

Cost price of manual = Fixed price + variable cost per package×Number of units sold

= 780000+19.85×1250000 = $25592500

Now we know Learning center wants a profit = $650000

Then profit = sale price - cost price

650000=sale price - 25592500

Sale price = 650000+25592500 = $26242500

This is the sale price of 1250000 units then selling price per unit should be = Total selling price/Number of units sold

= $26242500/1250000 =20.994 or $21

Selling price should be $21 per unit.

If you bought something in Colorado for $80, you would be charged $2.32 in state sales tax. What is the state sales tax in Color
REY [17]


The state sales tax in Colorado is 2.9%.

We know that because we divide 2.32/80. We have to find out what percent the tax is of the amount paid. The answer comes to 0.029. Multiply it by 100, and you get 2.9%
