0.4 is

and that simplified is

because you take the GCF or Greatest Common Factor, which is two, and divide both parts of the fraction taking

and turning it into
The y-intercept of the given function is (0, -5)
<h3>y-intercept of an equation</h3>
Given the equation below
y=[x-4| +1
The y-intercept is the point where the value of x is zero. Substitute x = 0 into the function to have;
y = 0 - 4- 1
y = 0 - 5
y = -5
Hence the y-intercept of the given function is (0, -5)

In order to find the volume of the tank, you just need to use this formula :
V = π r^2 h
r = 101.5 ft (half the diameter)
h = 25 ft
V = π (101.5)^2 x 25
= 809462.5 ft^3
hope this helps
The rate of change of a function with respect to a variable. ... Geometrically, the derivative of a function can be interpreted as the slope of the graph of the function or, more precisely, as the slope of the tangent line at a point.
How much did you multiply the concentrate by to get 6?
4. You need to even out the equation by multiplying 3.5 by 4 as well. 3.5*4 = 14. Add this to the 6 cups of concentrate (You don't want just water!) to get 20 cups. 20 cups is equal to 1.25 gallons or 5 quarts. (:
