Answer:
The answer is below
Step-by-step explanation:
The bottom of a river makes a V-shape that can be modeled with the absolute value function, d(h) = ⅕ ⎜h − 240⎟ − 48, where d is the depth of the river bottom (in feet) and h is the horizontal distance to the left-hand shore (in feet). A ship risks running aground if the bottom of its keel (its lowest point under the water) reaches down to the river bottom. Suppose you are the harbormaster and you want to place buoys where the river bottom is 20 feet below the surface. Complete the absolute value equation to find the horizontal distance from the left shore at which the buoys should be placed
Answer:
To solve the problem, the depth of the water would be equated to the position of the river bottom.

Answer:
286 miles / x gallons = 15miles per gallon.
286/15 = x = approximately 19.07 gallons.
Step-by-step explanation:
Answer:
455 square kilometers
step-by-step explanation:
a = l • w
24 • 24
576
because there is a space where it isn’t shaded we have to find the area of that as well
11 • 11
121
now just subtract
576 - 121
455
Answer:
1.8 gallons would be used.
Step-by-step explanation:
TOTAL AREA TO BE PAINTED:
2 x 10 x 20 + 2 x10x 16 = 720 ft2
720 ft2 / 400 ft2 /gal = 1.8 gal
