Answer:
a) x=
10°
50°
130°
10°
50°
130°
170°
250°
290°
b) x=
90°
210°
330°
Step-by-step explanation:
2 sin (3x) = 1
a) look at the graph, y=1 when x is near:
10°, 50°, 130°, etc
in the equation: 2 sin (3x) = 1 ⇒ sin (3x) = 0.5 ⇒ 3x = 30° (and others) ⇒ x = 10° (and others). So the values given in solution (10°, 50°, 130°, etc) are true
b) is evident
Answer:
you will need to find the difference (subtract) between two of the y points then do the same for the x points and put to difference of y on top of x and there is you slope using a graph( or if eaven, will come put as a whole number
The constant of proportionality is x=y/5 because its the constant that is not changing in he proportion. It represents the total of members made for washing x cars.
Answer:
divide the equation by 5
Step-by-step explanation:
all the components are factors of 5 so if we divide by 5, then we get as x² - 2x = -1
