Question 2
evablogger [386]

The domain of the function is x ≤ 6.88

The domain of the function is y ≤ 20

<h3>Domain and Range</h3>
  • These are input and output values for which the function exists

Given the function of x expressed as:

y = 3.5x + 2.8

The domain occurs at the point where 3.5x + 2.8 ≤ 20

3.5x ≤ 20 - 2.8

3.5x ≤ 17.2

x ≤ 6.88 - Domain

This given the domain of the function.

The range of the function is the point where y ≤ 20

Big Ben (the clocktower) in London has a circumference of 72.22 feet and an area of 415.27 feet^2. What is the diameter AND radi
Mashutka [201]

Answer:

Diameter = 23  Radius = 11.5

Step-by-step explanation:

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

<em>72.22 ÷ 3.24 = 23</em>

diameter = 23

Divide the diameter by 2.

<em>23 ÷ 2 = 11.5</em>

There you go, you found the circle's radius
