Depth: 7/2 feet
Rate: 5/4 feet per hour
Time = depth / rate of filling
Time = 7/2 / 5/4
Time = 14/5
Time = 2 4/5 hours
Area of a triangle=bh/2
27= x(x-3)/2
27= (x^2-3x)/2
54= x^2-3x
x^2-3x-54=0
(x-9)(x+6)=0
x=9, x=-6.
In this case, x must equal 9 since the base cannot be a negative number.
Final answer: Height=6 m
It really depends on what month or year. but typically a month is 4-5 weeks so it's either 16 or 20 miles
All of the powers of x here are even, so the function f(x) is even. Note that 19 = 19x^0 = 19(1) = 19
