Step-by-step explanation:
When the sum of two angles is equal to 90 degrees, they are called complementary angles.
So
x + x + 50° = 90°
2x = 90° - 50°
2x = 40°
x = 40°/2
x = 20°
x + 50 = 20 + 50 = 70°

Answer:
for the domain, find the point on the farthest side (the left) and the closest (the right)
so for yours it would be [-3,2]
it's brackets because the points are closed.
for the range, same thing but for the y intercept.
so it's [-2,4]
there's your answer!
Answer:

Step-by-step explanation:
1) Multiply both sides by 3.

2) Use this rule: a/b × c = ac/b.

3) Simplify 4 × 3 to 12.

4) Simplify 12/9 to 4/3.

Therefor, the answer is, t = 4/3.
and in decimal form it would be, 1.333333.
Answer:
- amplitude: 3
- period: π
- axis: y = 0
- range: [-3, +3]
Step-by-step explanation:
The amplitude is the multiplier of the sine function: 3.
The period is 2π divided by the coefficient of x: 2π/2 = π.
The equation of the axis is any added constant: y = 0.
The range is the axis value ± the amplitude value: from -3 to +3.
