Answer:
The height as a function of time is
h(t) = -(1/2)gt2 + v0t + h0
h(t) = -16t2 + 32t + 20
The ball reaches the ground when h(t) = 0
-16t2 + 32t + 20 = 0
Solve this quadratic equation for t. You will get a positive solution and a negative solution. Discard the negative solution, since time begins at t=0 at the moment the ball is struck. Can you finish from here?

Answer:
1) 57°
2) 142°
3) 92°
4) 125°
5) 111°
6) 90°
Step-by-step explanation:
Assuming the 2 lines that look parallel in all of these problems, are actually parallel...
m<1 = 57° They are the same angle
m<HJK = 142° (again, same angle)
m<ABC = (4x = 3x + 23) solve for x
x = 23, then substitute 23 for x
4(23) = 92°
m<MPQ = (3x + 50 = 5x). solve for x
x = 25, then substitute 25 for x
3(25) + 50 = 125°
m<3 = 111° They are the same angle
m<4 = 90° If one angle is 90° where the lines cross, all of the angles are 90°

Given the points (20,8) and (10,15) find the slope of the line that goes through them.
Answer:
-7/10
Step-by-step explanation:
You can find the slope by using this formula: [tex]\frac{y-y}{x-x} \\[/tex] (rise over run!)
If you plug in the numbers, it looks like this: [tex]\frac{8-15}{20-10} \\[/tex]

What is 127 to the nearest whole number
Answer: 127 to the nearest whole number is 130
Step-by-step explanation:
Since 7 is more than 5, we add 1 to the tenth place (2) which becomes 3 and add that to the original number (7) which gets you 10. After that you add 120 to 10 which gets you 130, therefore, the nearest whole number is 127.

solve for x
3(3x-8)-5(3x-8)=(4x-16)-6(x-2)
Answer:
the answer should be 5
Step-by-step explanation:
Remove parentheses.
3(3x-8)-5(3x-8)=4x-16-6(x-2)3(3x−8)−5(3x−8)=4x−16−6(x−2)
2 Simplify 3(3x-8)-5(3x-8)3(3x−8)−5(3x−8) to -2(3x-8)−2(3x−8).
-2(3x-8)=4x-16-6(x-2)−2(3x−8)=4x−16−6(x−2)
3 Expand.
-6x+16=4x-16-6x+12−6x+16=4x−16−6x+12
4 Simplify 4x-16-6x+124x−16−6x+12 to -2x-4−2x−4.
-6x+16=-2x-4−6x+16=−2x−4
5 Add 6x6x to both sides.
16=-2x-4+6x16=−2x−4+6x
6 Simplify -2x-4+6x−2x−4+6x to 4x-44x−4.
16=4x-416=4x−4
7 Add 44 to both sides.
16+4=4x16+4=4x

If you walk to school at a rate of 3 miles per hour how long will it take you to walk 6 miles
Answer:2 hours
Step-by-step explanation:3×2=6 sorry if its wrong
The number of hours when he has to walk 6 miles will be 2 hours.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
If you walk three miles per hour to school. The number of hours when he has to walk 6 miles will be given as,
3 = 6 / T
Simplify the equation, then we have
3 = 6 / T
T = 6 / 3
T = 2 hours
The number of hours when he has to walk 6 miles will be 2 hours.

Answer:
100 + 50h
Step-by-step explanation:
Given
Represent the hour with h.
Insurance Fee = $100
Hours = h
Cost per hour = 50
Required
Determine an algebraic expression
The expression is as follows:
Expression = Insurance Fee + Cost per hour * number of hours
Expression = 100 + 50 * h
Expression = 100 + 50h
The coefficient in the question is the number of hours (h)

point M with coordinates (3,4) is the midpoint of the line AB and A has the point (-1,6). what is the point of B?
Answer:
B = (7, 2)
Step-by-step explanation:
B = 2M -A
B = 2(3, 4) -(-1, 6) = (2·3-(-1), 2·4-6)
B = (7, 2)
_____
The expression for the other end point, B, comes from the equation for the midpoint.
M = (A +B)/2
2M = A + B . . . . . multiply by 2

For a special movie premiere, the theater owner decided to charge $20 per ticket for the first r rows of the theater and $15 for the remaining rows. 2. Explain how you could find the owner's total income if you knew the value of r and you knew that all tickets were sold. 3. Suppose r=16. A. Find the income in the first r rows if all of the tickets were sold. B. Find the income in the remaining r rows if all of the tickets were sold. C. Find the total income for r=16. 4. Write and simplify an expression for the owner's profit if tickets are priced at $20 per ticket in the first r rows and $15 per ticket in the remaining rows, if all seats are sold. 5. Evaluate the expression you wrote in Question 4 for r=16 and show that the result equals your answer in Question 3c.
Answer & Step-by-step explanation:
2. Total income = Income from first r rows + Income from other last rows
[(Price per first r rows' seat ) x (no of first r rows) x (no of seats per first r row) ] + [ (Price per other last rows' seat ) x (no of last rows) x (no of seats per last row) ]
= [ 20 x (r) x (no of seats per first r row) ] + [ 15 x (other last ie 'total - r' rows) x no of seats per last row
3. 20 x 16 x (no of seats per first r row) = 320 x (no of seats per first r row)
4. 15 x (other last ie 'total - 16' rows) x no of seats per last row
