Tanα=y/x
α=arctan(y/x), we are given the point (3.2, 6.2) so:
α=arctan(6.2/3.2)°
α=arctan(1.9375)°
α≈62.7° (to nearest tenth of a degree)
Answer:
the scale factor of the dilation is -1/4
Answer:
x > 2
Step-by-step explanation:
2(x+5) = 2x + 10 -> 2x + 10 < 4+5x
Subtract 4 from each side.
2x +6 < 5x
Subtract 2x from each side
6 < 3x
2<x
So, x must be > 2
Answer:
81/42
Step-by-step explanation:
8 1/10 ÷ 4 1/5
81/10 ÷ 21/5
81/10 * 5/21
(81*5)/(10*21)
405/210
81/42
