Answer:
5.125 l
Step-by-step explanation:
F(x)=3x-2
g(x)=x^2
(g o f)(3)=?
(g o f)(3)=g(f(3))
x=3→f(3)=3(3)-2
f(3)=9-2
f(3)=7
(g o f)(3)=g(f(3))=g(7)
x=7→g(7)=7^2
g(7)=49
Answer: (g o f)(3)=49
Answer:

Step-by-step explanation:
we know that
The volume of a container is equal to the volume of a cylinder plus the volume of one sphere
Step 1
Find the volume of a cylinder
The volume of a cylinder is equal to

we have

substitute


Step 2
Find the volume of a sphere
The volume of a sphere is equal to

we have

substitute


Step 3
Find the volume of the container

Round to the nearest cubic centimeter

3 over 15 = 3/15 = 0.2
42/100 = 0.42
so order from least to greatest:
-0.5 , 3 over 15 , 42 over 100, 0.47
<h3>{ 13, 9, 6} represent the sides of a triangle</h3>
<em><u>Solution:</u></em>
<em><u>Use the triangle inequality law</u></em>
The sum of the lengths of any two sides of a triangle must be greater than the third side
<em><u>Option A</u></em>
{13, 9, 6}

Also,

Thus, sum of length of any two sides is greater than third side
Therefore, { 13, 9, 6} represent the sides of a triangle
<em><u>Option B</u></em>
{12, 7, 20}

19 is not greater than 20
Therefore, {12, 7, 20} does not represent the sides of a triangle
<em><u>Option C</u></em>
{25, 50, 75}

75 is equal to 75
Therefore, {25, 50, 75} does not represent the sides of a triangle
