Answer:
y=2, the equation of a line which is perpendicular to the line 3x+5=0
A(-5/3,2) the foot of the perpendicular from B to the line
Step-by-step explanation:
d1 : 3x+5=0, so 3x=-5, x=-5/3
y=2, the equation of a line which is perpendicular to the line 3x+5=0
A(-5/3,2) the foot of the perpendicular from B to the line
Answer:
The linear speed is ![1,130.4\frac{ft}{min}](https://tex.z-dn.net/?f=1%2C130.4%5Cfrac%7Bft%7D%7Bmin%7D)
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
we have
![r=18\ ft](https://tex.z-dn.net/?f=r%3D18%5C%20ft)
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![C=2(3.14)(18)](https://tex.z-dn.net/?f=C%3D2%283.14%29%2818%29)
![C=113.04\ ft](https://tex.z-dn.net/?f=C%3D113.04%5C%20ft)
step 2
Find the linear speed in feet per minute
we know that
The wheel is rotating at 10 revolutions per minute
Convert revolutions to feet
Remember that
One revolution is equal to the circumference of the circle
so
10 revolutions is equal to
![(10)113.04=1,130.4\ ft](https://tex.z-dn.net/?f=%2810%29113.04%3D1%2C130.4%5C%20ft)
therefore
The linear speed is ![1,130.4\frac{ft}{min}](https://tex.z-dn.net/?f=1%2C130.4%5Cfrac%7Bft%7D%7Bmin%7D)
Answer:
y = 2x
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Find slope <em>m</em>
2x - y = -4
-y = -2x - 4
y = 2x + 4
Since the 2 lines are parallel, they have the same slope.
Step 2: Define variables
Slope <em>m</em> = 2
Origin (x-int and y-int) (0, 0)
Step 3: Write parallel linear equation
y = 2x + 0
y = 2x
