The dimensions of a large room are double the dimensions of a small room.Both rooms are rectangular prisms. The volume of the small room is 10 cubic
metres.
What is the volume of the large room?

Answers

Answer 1

Answer: The volume would be 80 cubic metres. Think about the three different dimensions for the small room as x,y and z. Therefore the volume is x*y*z= xyz. Now for the bigger room, the dimensions would be 2x,2y and 2z. Therefore, its volume would be 2x*2y*2z= 8xyz. Since xyz (volume of the smaller room)= 10 cubic metres, the bigger room's volume will be 8*10= 80 cubic metres.

WILL CHOOSE BRAINLIEST! PLEASE HELP! 15 POINTS!Find the area of the shaded segment of the circle.

Answers

[(81*3.14)/4] - (81/2)

Answer:

The shaded segment = The arc area - The triangle

The arc area = pi x radius^2 x angle/360

= pi x 9^2 x (360-270)/360 = 63.61 (m2)

The triangle area = 9 x 9/2 = 41.5 (m2)

(because this is right triangle)

=> The shaded segment = 63.61 - 41.5 = 22.11 (m2)

What is the range of each function given below?
a. Let f(x) = 9x − 1.

Answers

Answer:

Range of f=R

Step-by-step explanation:

We are given that a function

$f(x)=9x-1$

We have to find the range of given function.

The given function is linear function because the degree of function is 1.

When the degree of function is 1 then the function is called the linear function.

The domain of linear function is a set of real numbers because it can be defined for all real values of x.

Domain of given function =R

When we substitute the real value of x in given function then we get a real number also.

Therefore, the range of f=R
