Answer:

Yes, the number of cells is a linear function (linear and a function).

Step-by-step explanation:

Ok, I may be wrong, but please don't hate me!!!

The number of cells is a function because the number of cells increased by the same amount (times 4 cells) each day.

The number of cells is linear because it increased by the same amount each day and if you placed this function on a graph, you could interpret the values of the number of cells without needing to know the function.

Simplify the following expression:
Salsk061 [2.6K]

Simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

The options are:

A) -x⁴ - 2x - x + 2

B) -x⁴ - 2x³ + 2x + 5

C) -2x³ + 1

D) -x - 2x² + 2x + 5

We have an expression:

= (x + 3) - [(x + 2)(x³ - 1)]

\rm =x+3-\left(x+2\right)\left(x^3-1\right)

\rm =x+3-x^4+x-2x^3+2

\rm =-x^4-2x^3+2x+3+2

\rm =-x^4-2x^3+2x+5

Thus, simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.

Pls help!! Find the volume of the flower vase. Round to the nearest tenth.
Contact [7]

Answer:

Volume = 1596.2 cubic cm

Step-by-step explanation:

Volume = volume of box - volume of cylinder

Volume = (LxWxH) - 1/3 (pi * r^2 *h)

Volume = (10 x 12 x 20) -1/3 (3.14 x 8^2 x 12)

Volume = 2400 - 803.8

Volume = 1596.2 cm^3
