These two lines cannot be perpendicular. For one line to be perpendicular to the second one, their gradients are related by the following:
Gradient of line 1 = -(1/gradient of line two)
In the current case, gradient of line 1=2 and gradient of line two = 1/2. If gradient of line two was = - 1/2, then they would be perpendicular.

Volume of a Cylinder Formula:
- V is volume
- r is radius
- h is height
Step-by-step explanation:
<u>Step 1: Define</u>
Radius <em>r</em> = 2 ft
Height <em>h</em> = 7 ft
<u>Step 2: Solve for V</u>
- Substitute in variables [Volume of a Cylinder Formula]:

3/4 of 80 is 60, so the distance is 60 km. 45/60 is 3/4, which is how you get the answer
Answer:
Step-by-step explanation:
Using a graphing calculator, plot (x,y) points
- x = no. of jobs
- y = no. of workers needed
and plot the functions from the options to know which function fits the data
