Answer:
81
Step-by-step explanation:
Substitute 3 in place of y
7 * 3 * 3 - 16 + 5 * 3 *2 + (16 / 4)
63 - 16 + 30 + 4
Answer:
The path length is the same for the small and large semicircles.
Step-by-step explanation:
The distance around the large semicircle = 1/2 * π * diameter
= 1/2*8*π
= 4π m.
The distance around the 2 smaller semicircles
= 1/2 * 4 * π + 1/2 * 4 * π
= 2π + 2π
= 4π m.
You can use the coordinates to find the slope of each line. If you can show the two slopes are equal, then the lines are parallel.
Side note: If the lines are vertical, and never cross, then they will be parallel despite having an undefined slope. This is one of the exceptions to the rule.
