Answer:

The volume of the figure is 905 cubic units.

Step-by-step explanation:

Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.

volume of a sphere = \frac{4}{3}\pir^{3}

where r is the radius of the sphere.

Given that AB = 6, then the radius of the sphere = 6

volume of sphere = \frac{4}{3} x \frac{22}{7} x (6)^{3}

                              = \frac{88}{21} x 216

                              = 905.14

volume of sphere = 905 cubic units

The volume of the figure is 905 cubic units.

1/4 (dot) 3/5 simplifily
stich3 [128]

Answer: 1/20 (fraction) or 0.05 (decimal)

Step-by-step explanation:

first i like to make them a decimal so its easier.

1/4 = 0.25

1/5 = 0.2

multiply 0.25 and 0.2 = 0.05

make 0.05 a fraction

1/20

simplify. (it's already in its simplest form)

the answer is 1/20 as a fraction or 0.05 as a decimal.

(i dont know which one ur teacher wants u to do fraction or decimal?)

Over what interval is the function in this graph increasing?
brilliants [131]

A function is increasing if it "points upwards".

Think that you have two inputs x_1 (think of them as being very close to each other). A function f is increasing if

f(x_1)

So, smaller input, smaller output.

So:

  • In the first segment on the left, the function is decreasing: if you move with little steps rightwards, the output will get smaller and smaller (the function points to the right bottom)
  • In the second segment, the line is constant (it's horizontal). This means that even if you consider a larger input, the output reimains the same
  • In the third segment, the function is increasing: if you consider a larger input, the output will be larger as well: the function points to the top right.
  • In the fourth segment, the function is decreasing again (look at the first bullet point)

So, the function is increasing in the third segment, which is delimited by

-2\leq x \leq 3
