To solve this problem, we must first convert the distance into miles:
distance = 60 ft (1 mile / 5280 ft) + 6 inches (1 foot / 12 inches) (1 mile / 5280 ft)
distance = 0.0114583 mile
To calculate for time:
time = distance / speed
time = 0.0114583 mile / (90 miles / 3600 seconds)
time = 0.458 seconds

Answer:
z>-9
Step-by-step explanation:
350gallons /minute
D = minimun depth of mine
4D-250 = minimum gallon per minute required to pump
4(150)- 250= 350gallon/minute
tan(θ) = 0, 0.577, -0.577
3tan³(θ) - tan(θ) = 0
tan(θ)(3tan²(θ) - 1) = 0
tan(θ) = 0
tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)
tan(θ) = 0, sqrt(⅓), -sqrt(⅓)
To find θ values, domain is required
