Answer: We all hate it when we are stuck! The slope is -1/2.
Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.

Answers
Answer:
the answer is 2.87
Step-by-step explanation:
use the pythagorean theorem
2^2+b^2=4^2
that goes to b= 3.5
for the triangle with x you also need to use the pythagorean theorem
[tex]2^{2}[/tex]+[tex]x^{2}[/tex]=[tex]3.5^{2}[/tex]
4+[tex]x^{2}[/tex]=12.25
subtract 4 on both sides
[tex]x^{2}[/tex]=8.25
[tex]\sqrt{x}[/tex]=[tex]\sqrt{8.25}[/tex]
x=2.87

Kahleela starts the engine on her small private airplane. The engine drives a propeller with a radius of 8.5 feet and its centerline 11.5 feet above the ground. At idle, the propeller rotates at a constant speed of approximately 800 revolutions per minute. The height of one propeller tip as a function of time is given by h = 11.5 + 8.5 sin(800t), where h is the height in feet and t is the time in minutes. Find h when t = 5.5 minutes.
Answers
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.

Consider the sequence of steps to solve the equation: 2(x – 4) + 6x = 9x – 10
Given = 2(x - 4) + 6x = 9x - 10
Step 1 = 2x - 8 + 6x = 9x - 10
Step 2 = 2x + 6x - 8 = 9x - 10
Step 3 = 8x - 8 = 9x - 10
Step 4 = 8x – 8x - 8 = 9x - 8x - 10
Step 5 = 0 - 8 = x - 10
Step 6 = -8 = x - 10
Step 7 = -8 + 10 = x - 10 + 10
Step 8 = 2 = x + 0
Step 9 = 2 = x

The angle of elevation from a boat to the top of a lighthouse is 50°.
If the boat is 150 feet from the base of the lighthouse, how tall is the lighthouse?
Round answer to the nearest foot.
Answers
9514 1404 393
Answer:
179 ft
Step-by-step explanation:
The applicable trig relation is ...
Tan = Opposite/Adjacent.
The height of the lighthouse is the opposite side of the right triangle. The adjacent side to the angle of elevation from the boat is the distance to the lighthouse base. Then ...
tan(50°) = height/(150 ft)
height = (150 ft)(tan(50°)) ≈ 178.76 ft
The height of the lighthouse is about 179 feet.

Side z is the hypotenuse, since it is opposite the right angle.
Side x is the adjacent, since it is next to the angle you are solving for.
The side measuring 26 is the opposite, since it is opposite the angle you are solving for.

Answers
The first thing I do with a line is sub in 0 for x. This will give you the y intercept. On the graph, we can see that the y intercept is (0,5). So, the equation we use has to have an output of 5 if we plug in 0. The only one this applies to is equation B.
