Arctan(53/22) = 67.5 degrees
Answer:
A. 32
Step-by-step explanation:
If the center is (0, 0) and a point is (0, 4) then the distance from the center to that point is 4 units. That distance is the radius. If you are dilating by a factor of 4, multiply the radius by 4 and you get 16. The new radius is 16 and the diameter= radius*2.
16*2=32
Answer: $76 will be the total for one and a half ours for a repair.
Step-by-step explanation:
28 + 16hh
hh = half hour
1 and a half hours = 3 half hours
28 + 16(3)
28 + 48 = 76
The percent of the mark down would be 10%. If you subtract 81 from 90, you get 9. Then divide 90 by 9 and you get 10. Hope this helps!
Answer:
x^2 - 6x - 7
Step-by-step explanation:
Roots, 7 and -1
x = 7 is the same as x - 7 = 0
x = -1 is the same as x + 1 = 0
multiply (x-7) by (x + 1)
x(x -7) +1(x - 7)
x^2 -7x + x - 7
x^2 - 6x - 7
