What you want to do is get the variable x on the left side by itself (just like you would if this were an equation). Be sure to perform the same operations on both sides of the inequality until x is all by itself on the left side.

Volume of a Cone Formula: $\displaystyle V = \frac{1}{3} \pi r^2h$

<em>r</em> is radius
<em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

Radius <em>r</em> = 4

Height <em>h</em> = 21

<u>Step 2: Find Volume</u>

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (4)^2(21)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (16)(21)$
Multiply: $\displaystyle V = \frac{16 \pi}{3}(21)$
Multiply: $\displaystyle V = 16 \pi \cdot 7$
Multiply: $\displaystyle V = 112 \pi$

Compute Δy using the function y= 5x^3 as x goes from -2 to 1.<br> Δy =?

Elenna [48]

The value of Δy using the function y= 5x^3 as x goes from -2 to 1 is; Δy = 45

The question requests that Δy be computed according to the function, y = 5x³ as x goes -2 to 1.

Δy = y2 - y1

where:

y1 = 5(-2)³

y1 = -40

and

y2 = 5(1)³

y2 = 5

Therefore,

Δy = y2 - y1

Δy = 5 - (-40)

Δy = 45.

A student's bank account is represented in the table shown.

melomori [17]

The desmos link is in the reply section below...

1.) y = 1.56x + 1.29

2.) the slope is 1.56

As the weeks are increasing, the student's balance is growing about 1.56 per week.

3.) y = 24.69

4.) 50 = 1.56x + 1.29

50 - 1.29 = 1.56x + 1.29 - 1.29

48.71 =1.56x

48.71 / 1.56
