Find small changes in cube's volume when its side increses from 10 cm to 10.1 cm
garik1379 [7]

Answer:

1030 cm^3 (1030.30 cm^3)

Step-by-step explanation:

The volume of a cube is a side length cubed (x^3).

If you have a side of 10 cm (10^3 = 1000) the volume would be 1000 cm^3. To find the volume of a cube with side lengths 10.1 cm, use the formula x^3.

10.1^3 --> (10.1)(10.1)(10.1) = 1030.301

The cube would be 1030.30 cm^3, or if rounded to the nearest whole number 1030 cm^3.

State whether the data described below are discrete or continuous, and explain why. The amounts of time that different surgical
zepelin [54]

Using variable concepts, it is found that the amounts of time that different surgical procedures take at hospital is continuous.

<h3>What are continuous and discrete variables?</h3>
  • Continuous variables: Can assume decimal values.
  • Discrete variables: Assume only countable values, such as 0, 1, 2, 3, ...

In this problem, the amounts of time that different surgical procedures take at hospital can be decimal, for example 10.5 minutes, hence it is a continuous variable.

Select the correct answer.<br> Which function is the inverse of function<br> f(x) = -2
Artemon [7]

Answer:

B

Step-by-step explanation:

let f(x) = y and rearrange making x the subject

y = \frac{x+2}{7} ( multiply both sides by 7 to clear the fraction )

7y = x + 2 ( subtract 2 from both sides )

7y - 2 = x

Change y back into terms of x with x the inverse function, that is

p(x) = 7x - 2
