Answer:
Point Slope equations:
Slopes:
- 3
- -9
- 5
Points on the line:
- (5,6)
- (-8,4)
- (0,2)
Step-by-step explanation:
Basically we use this formula to solve each column
m = slope
5^2-(2*8+9)
pemdas
first do the parentheses
2*8+9
16+9=25
next do the exponent.
5^2=5*5=25
25-25=0
The magnitude of the force per unit length between the wires is .
<h3>What is the magnitude of the force?</h3>
In a wire carrying a current I 2, the force that each wire feels due to the presence of the other depends on the distance between them and the magnitude of the currents.
Force per unit length = magnetic permeability * (current 1) * (current 2) / (2 π distance between the wires).
The below expression for the force per unit length.
Moreover, before using the below formula we have to change the unit centimeter into a meter. So, we just divide the centimeter by 100.
Substitute all the values in the formula
Hence, the magnitude of the force per unit length between the wires is .

Answer:
y($) = 405- 20x
Step-by-step explanation:
Number of short driveways = x
Number of long driveways = 9-x
Fee per long driveway = $45
Fee per short driveway= $25
Total amount = y
y ($) = 25x + 45 (9-x)
= 25x + 405 -45x
= 405- 20x
