Answer:
Equation of line is given by:
Step-by-step explanation:
Given points:
Slope of line 
where 
and 
is a point on the line
∴ 
Point-slope equation of line is given by:
where is a point on the line and 
is slope of line.
Using point 
and slope point-slope equation of line is given by:
Simplifying.
Using distribution.
Subtracting 2 to both sides.
Thus, equation of line is
first step is do the parentheses ( -3÷-.5) = 6
6+-8=-2
Answer:
Step-by-step explanation:
circumference = pi * diameter
circumference of metal frame = pi * (diameter of metal frame)
(diameter of metal frame) = 12
Circumference of Metal Frame = 3.14 * 12 = 37.68
therefore D: 37.7 feet would be your answer
Answer
A) 2160 cubic inches
Step by step explanation
Volume of a rectangular prism = length *width*height.
The give figure (stairway) consists of two rectangular prism.
The volume of the first rectangular prism (bigger one) = 12 *10*12
=120*12
1 st prism = 1440 cubic inches
The volume of the rectangular prism 2 (smaller one) = 12*10*6
=120*6
The volume of the rectangular prism 2 = 720 cubic inches
The volume of the concrete stairway = Volume of the prism 1 + Volume of the prism 2
= 1440 + 720
The volume of the concrete stairway = 2160 cubic inches.
Thank you.
