Answer:

a) 0.6435 radians

b) 80.1 feet/sec

Step-by-step explanation:

a) 75 = (50²/16)sin(theta)cos(theta)

sin(theta)cos(theta) = 0.48

2sin(theta)cos(theta) = 0.96

sin(2theta) = 0.96

2theta = 1.287002218

Theta = 0.6435011088 radians

b) 200 = (v²/16)sin(0.75)cos(0.75)

6416.072347 = v²

v = 80.10038918 feet/sec

You build and sell toy cars for $36 each. So far, you have built 25 toy cars. How many more toy cars will you have to build and
chubhunter [2.5K]
If you have built 25 cars, and they are 36 dollars per, then multiply 25 and 36 for the amount of money.  This will result with 25*36=900.  Since we already have 900 dollars worth, we subtract that from the goal of 1620, leaving us with 1620-900=720.  Now, divide this by the price per car for the amount of cars needed to get to this goal. 720/36=20 cars

Hope this helps!
