Answer:
Step-by-step explanation:
Answer: r = -5/18
Step-by-step explanation: You solve -3(1+6r)+12=14
-3-18r+12=14 (When distributed)
-18r+9=14
-18r=5
r=-5/18
Answer:
its a right ray
Step-by-step explanation:
Answer:
x=6/31, y=147/31. (6/31, 147/31).
Step-by-step explanation:
y=-22x+9
y=40x-3
-----------------
-22x+9=40x-3
9=40x-(-22x)-3
9=40x+22x-3
9=62x-3
62x=9+3
62x=12
x=12/62
simplify,
x=6/31
-----------------
y=40(6/31)-3=240/31-3=240/31-93/31=147/31
x=6/31, y=147/31.
Answer:
46.8 m (nearest tenth)
Step-by-step explanation:
To find the <u>height</u> of the kite, model the scenario as a <u>right triangle</u> and solve using the <u>sine trigonometric ratio</u>.
<u>Sine trigonometric ratio</u>
where:
- is the angle.
- O is the side opposite the angle.
- H is the hypotenuse (the side opposite the right angle).
Given information:
- = Angle of elevation = 42°
- O = Height
- H = Length of string = 70 m
Substitute the given values into the formula and solve for height:
Therefore, the height of the kite is 46.8 m (nearest tenth).
