PLEASE HELP ASAP!!!!!!
solmaris [256]

the answer would be x=6

to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent

hope this helps :)

A cylinder has a volume of 200in^3. Determine the volume of a cone whose radius and height are equal to that of the cylinder
katrin [286]

Answer:

66.67 in^3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone =  1/3(nr^2h)

n = 22/7

r = radius

the volume of a cone is 1/3 that of a cylinder

volume of the cone = 1/3 x (200) = 66.67 in^3

Use the rational zero thereom to list all possible zeroes of the function f(x)= 5x^8-2x^5-7
Scrat [10]

Possible rational zeros are:

\pm1,\pm7,\pm\frac{1}{5},\pm\frac{7}{5}

Step-by-step explanation:

We need to list all possible zeroes of the function f(x)= 5x^8-2x^5-7 using rational zero theorem.

The rational zero theorem.

rational zero theorem states that zeros can be found by dividing the factors of constant term called p by the factors of the leading co-efficient called q i.e

p/q

In our given function  f(x)= 5x^8-2x^5-7

p = 7

q = 5

Factors of p (7) = ±1, ±7

Factors of q (5) = ±1, ±5

\frac{p}{q} =\frac{\pm1,\pm7}{\pm1,\pm5}

So, possible rational zeros are:

\pm1,\pm7,\pm\frac{1}{5},\pm\frac{7}{5}

Keywords: rational zero theorem, possible zeroes
