Answer: 25.13cm is the circumference of the diameter of 4cm.
Answer:
From the graph, the y-intercept is 9 and the slope is -1 so the equation is y = -x + 9. We know the slope is -1 because when x goes up by 1, y decreases by 1.
The solutions of the equation 
² - 16 = 0is 4/3 and -4/3 and that of the equation 
is 8 and -4.
Solving the both quadratic equations by extracting square roots:
⇒ 
∴ On taking square-root of both sides, we get
= 
⇒ 
and 
⇒ 
= 4/3 and = -4/3
For the equation, , the solution is:
⇒ 
∴ On taking square-root of both sides, we get
⇒ (z - 2) = 6 and (z - 2) = -6
⇒ z = 6 +2 and z = -6 + 2
⇒ z = 8 and z = -4
The solution of the equation is 4/3 and -4/3.
The solution of the equation is 8 and -4.

The tree to the edge of the path acts as a radius. use the formula to find a circles perimeter to find the length of the path, which is 2r(pi). 2r=1.5, so multiple that by pi. if pi is simplified to 3.14, the circumference of the circle/length of the path would be 4.71 miles.
Answer:
D(72)
Step-by-step explanation:
to find this do 40 + 40 to get 200 percent of the original year when subtract 20 percent of 40 to get 72
