Answer:
Step-by-step explanation:
Add all of the times spun to get 70. To get 16/70 then divide by 2 to get 8/35.
A. Total amount raised, A, equals 92 sponsors times number of kilometers, n, times $1 per kilometer, plus additional donations, d.
b. Yes. Write an equation based on the verbal model: A = 92n +d. Substitute the information from the problem into the equation and solve for d: 842 = 92(8) + d. The amount of money from additional donations is $106.
A 45 degree angle is 1/8 of a circle, so keep that in mind for later. You're looking for the circumference of that 1/8 fence, so you have to use the formula, circumference/diameter=pi. Now, the problem gives you half the diameter, a.k.a the radius, so double it to get 44 ft. then, you multiply that by 3.14 (pi) to get 138.16. Now take the 1/8, from before, of the circumfrence and you get your final answer, 17.27 ft!
-2x+4=3
move the 4
-2x+4=3
-4 -4
-2x=-1
then you would move the -2 by using division
-2x=-1

-2 -2
x=0.5
Answer:
F'(17, - 8 )
Step-by-step explanation:
Under a rotation about the origin of 180°
a point (x, y ) → (- x, - y ), thus
F(- 17, 8 ) → F'(17, - 8 )
