2/2 = 1  and (1/3)^0 = 1  so x/x = 1 because there is same number and (x/y)^0= 1 because its 0 and 1/1 is always 1 these are the fractions that are always 1 :))
i hope this be helpful

You would know because for example, if it's out of 4 and the fraction said 4/4, that would mean one. 3/3 would mean one. 2/2 and so on

What is the discontinuity and zero of the function f(x) = 3x^2 + x - 4 / x-1
7nadin3 [17]
Ans: Option (1) <span>Discontinuity at (1, 7), zero at ( negative four thirds , 0) 
</span>
Explanation:
Given function:
f(x) =  \frac{3x^2 + x - 4}{x-1}

Now if we plug in the x = 1, we would have discontinuity as function goes to infinity.

Now for f(1):
f(x) = \frac{3x^2 + x - 4}{x-1} \\ f(x) = \frac{3x^2 + 4x - 3x - 4}{x-1} \\ f(x) = \frac{x(3x+4)-1(3x+4)}{x-1} \\ f(x) = \frac{(x-1)(3x+4)}{(x-1)} \\ f(x) = 3x+4 \\ now ~ insert ~ x=1: \\ f(1) = 3(1) + 4 = 7 \\ It~means~discontinuity~at~(1,7).\\ Now~let~us~find~zeros.\\ put~ f(x) = 3x+4 ~ equals~ to ~zero. \\ =\ \textgreater \ ~3x+4 = 0 \\ =\ \textgreater \  ~ x =  \frac{-4}{3} \\ Hence~zeros=(  \frac{-4}{3}, 0)

cylinder has a height of h inches and a diameter of 3 inches. What expression gives the volume of the cylinder in cubic inches?
pashok25 [27]

Answer:

The expression that gives the volume of the cylinder in cubic inches is V=\frac{9\pi h}{4} \:in^3.

Step-by-step explanation:

The base of a cylinder is a circle, the area of that circle is given by the formula:

area = \pi r^2

Multiplying by the height h we get that the volume of a cylinder is

V=\pi r^2h

where:

π = Pi

<em>r</em> = the radius of the circular end of the cylinder

<em>h = </em>height of the cylinder

We know that the cylinder has a height of <em>h</em> inches and a diameter of 3 inches.

The radius of a circle is half the diameter and the volume is:

V=\pi (\frac{3}{2}) ^2h=\frac{9\pi h}{4} \:in^3
