Anytime we need to get the equation of a line, we need 2 things:

a point a slopeSo, what do we do if we are just given 2 points and no slope?No problem -- we'll just use the 2 points to pop the slope using this guy:

Check it out:

Let's find the equation of the line that passes through the points

(1,1/2) and (-1,-1)

This one's a 2-stepper...

STEP 1: Find the slope

STEP 2: Now, use the point-slope formula with one of our points,

If the circumference of a circle is about 15.4 cm, estimate to the nearest whole number the diameter of the circle

nasty-shy [4]

The nearest whole number the diameter of the circle is 5.0 cm.

Given the following data:

Circumference of a circle = 15.4 cm

To estimate to the nearest whole number the diameter of the circle:

In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.

<h3>How to calculate the circumference of a circle.</h3>

Mathematically, the circumference of a circle is given by the formula:

$Circumference = \pi D$

Where:

D is the diameter of a circle.

Making D the subject of formula, we have:

$D =\frac{circumference}{\pi}$

Substituting the given parameters into the formula, we have;

$D =\frac{15.4}{3.142}$

D = 4.90 cm

To the nearest whole number:

D = 4.90 ≈ 5.0 cm

Which number is irrational

alexgriva [62]

Answer: Choice A) sqrt(17)

The square root of 17 is irrational because we cannot write this number as a fraction of two whole numbers (see note below). With something like choice B, we can do so and that would be 6/99; while choice C simplifies to 7 which is equivalent to 7/1. Choice D isn't fully visible, but it appears to be a fraction of two whole numbers.

Note: the denominator of the fraction cannot be 0.
