This depends on how many pages you read all together. I don't fully understand what the question is that you are asking. Could you try to explain it a little bit more? If you can then I could probably help you out :)

The wind force f on a sail varies jointly as the area a of the sail and the square of the wind speed w.

blondinia [14]

Answer:

122.5 lbs

Step-by-step explanation:

The relation between force, wind speed, and area can be written ...

f = ks²a

for some wind speed s and area a.

The constant of proportionality, k, can be found from the given data.

64.8 = k(18²)(500) . . . force in pounds, area in square feet, speed in mph

k = 64.8/(324×500) = 0.0004

Using the equation with the second set of data, we have ...

f = 0.0004(35²)(250) = 122.5 . . . . pounds

The force on the 250 square foot sail would be 122.5 pounds.

1 Solve the compound inequality 4x>-16 or 6x <-48

Yuliya22 [10]

Answer:

Step-by-step explanation:

4x > -16 reduces to x > -4: All numbers greater than x = -4 (shaded area to the right of -4).

6x < -48 reduces to x < -8: All numbers to the left of -8 (shaded area to the left of -8).

Solution: (-infinity, -4) ∪ (-8, infinity)

The number line between -8 and -4 is not part of the solution set (is not shaded or darkened)

Draw an open circle at -8 and extend an arrow to the left of this circle. Then draw an open circle at -4 and extend an arrow to the right of this circle.
