Step-by-step explanation:
Q3
Corresponding angles are congruent
- 6x - 11 = 37
- 6x = 11 + 37
- 6x = 48
- x = 8
Q4
Angle2 is complementary with 142 and alternate interior with 2(x + 9)
- 142 + 2(x + 9) = 180
- 142 + 2x + 18 = 180
- 2x + 160 = 180
- 2x = 20
- x = 10
Answer:
(a) θ = π + 4πn
(b) θ = π
Step-by-step explanation:
(a) sin(θ/2) − 1 = 0
sin(θ/2) = 1
θ/2 = π/2 + 2πn
θ = π + 4πn
(b) Try different values of n.
n = -1, θ = -3π
n = 0, θ = π
n = 1, θ = 5π
If 0 < θ < 2π, then θ = π.
Answer:
100
Step-by-step explanation:
You start with multiplication. -1 * -9 is 9. Then you add 1 and 9, which is 10. Lastly, you do 10 to the second power(10 * 10), which comes out as 100.
Answer:
Duration Recording
Step-by-step explanation:
This method records the percent of time or total time that a person exhibits a behaviour over a period of time. This type of measurement is normally used to measure behaviours that are exhibited at high rates. Normally the measurement are done from the onset of the behaviour to the moment the behaviour stops.
