The equation in the problem solves the speed as 48.99 miles per hour. At this speed the car takes 100 feet to stop ( also shown in the equation as they replaced d with 100).

This means any speed below 48.99 miles per hour would stop before hitting the tree.

The fastest the car can go would be 48.98 miles per hour.

Justify by replacing s in the equation with 48.98 and solve for d:

48.98 ^2 = (sqrt( 30(0.8)d)

2399.04 = 24d

D = 2399.04/24

D = 99.96 feet

This is less than 100 feet so the car will not hit the tree.

Please help me create a function<br> Correct answer gets brainiest :)
slega [8]
Let y be Justin base pay, w% be commission,
y + w%*600=350-----(1)
y+w%*900= 425-----(2)
From equation (1),
y = 350- w%*600 = 350-6w-------(3)
Substitute equation (3) into (2),
350-6w+9w=425
3w = 425-350= 75
w= 25
y = 350-6w= 350-6(25)= 200
so the function is base pay +25%of merchandise
Final answer is $ (200 + 0.25x)

A shipping company charged $15 to ship a package and 5% of the shipping charge for insurance on the package. What was the total
pickupchik [31]
Take $15 and multiply it by 0.05 (this will get you the percent). You should get 0.75. So you add 0.75 to $15 and you should get $15.75
