Find the circumference of the circle and round to the nearest tenth
VLD [36.1K]

Answer:

The circumference is 45.2yd

Step-by-step explanation:

Given

d = 14.4 --- diameter

Required

Determine the circumference

The circumference is calculated as:

C =\pi d

So, we have:

C =\pi * 14.4

Take pi a 3.14

C =3.14 * 14.4

C =45.216

Approximate

C =45.2yd

A line passes through the two points (-4,6) and (2,-5). Calculate the following parts:
Viktor [21]

A line passes through the two points (-4,6) and (2,-5). 11x +6y - 80 = 0 is the given line equation.

<h3>What is the slope of a line which passes through points ( p,q) and (x,y)?</h3>

Its slope would be:

m = \dfrac{y-q}{x-p}

The slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

The slope m of the line is given as

m = \dfrac{y-q}{x-p}\\\\ m = \dfrac{-5-6}{2+4}\\\\ m = \dfrac{-11}{6}

The equation of a line is  

( y -y_0) = m (x - x_0)\\\\( y -6) = \dfrac{-11}{6}  (x+4)\\\\6( y -6) = (-11)  (x+4)\\\\6y -36 = (-11x +44)\\\\11x +6y - 80 = 0

Hence, the equation is  11x +6y - 80 = 0
