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.
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.
Answer:
A. 3.1 feet is the answer i believe.........

The polygons are similar. Find the values of
the variables. Write an equation and solve,
showing ALL the work.
Answer:
x=30° y=4
Step-by-step explanation:
[tex] \frac{y}{8} = \frac{2.5}{5} [/tex]
cross multiple
5y=8(2.5)
5y=20
divide 5 by 20
and you should y=4
since the polygons are similar x should have the same degrees as the bigger polygon
Answer: Y=4
Step-by-step explanation
Since the inside of a triangle is 180 degrees the 30 degrees plus the 90 degree corner minus the total inside degree so the other corner is 60 degrees. the dialation is 62.50 percent or .625 in decimal form which makes the vareable y equals 4 once you divide 2.5 by .625

Find the slope of each linear graph to solve the riddle.
( i just need help with V)
Answer:
slope=15÷10=1.5 or 3/2
Step-by-step explanation:
slope=rise÷run
10 right 15 up
slope=15÷10=1.5 or 3/2
The slope is calculated as the ratio of the rise and run. The slope of the given line will be [tex]\dfrac{3}{2}[/tex].
In mathematics, slope refers to the measure of the steepness or inclination of a line. It describes how much a line slants or rises/falls as it moves horizontally.
A positive slope means the line is upward-sloping, rising from left to right, while a negative slope indicates a downward-sloping line.
The slope can be calculated by the ratio of the rise and the run. The points on the given graph are A(10,30) and B(20,45). The slope is calculated by the formula written below,
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
The slope of the line is calculated below
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}\\m = \dfrac{45-30}{20-10}\\m = \dfrac{3}{2}[/tex]
The slope of the line will be [tex]\dfrac{3}{2}[/tex].

For questions 1-4, find the distance between points A and B. Round your solutions to the nearest tenth when necessary.
Answer:
1. AB= 8.94,
2. AB= 7.28
3. AB= 16.4
4. AB= 19.21
Step-by-step explanation:
This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.
4 units from a to e and 8 b to e
a² + b² = c²
8² + 4² = c²
64 +16 = c
√80 = √c²
8.94 = c
It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.
Follow the same steps for the rest of the problems.

A school requires that 1 adult accompany every 8 students on a field trip. How many adults are needed to accompany 32 students?
Answer: 4 adults are needed to accompany 32 students.
Step-by-step explanation:
Given: School requires 1 adult to accompany every 8 students on a field trip.
The number of adults are needed to accompany 32 students = [tex]\dfrac{32}{\text{Number of students accompanied by an adult}}[/tex]
[tex]=\dfrac{32}{8}\\\\=4[/tex]
Hence, 4 adults are needed to accompany 32 students.

Solve the inequality. 5(x + 1) – 10 ≥ 2x + 3(x + 2)
The solution of the inequality 5(x + 1) - 10 ≥ 2x + 3(2x + 2) is x ≤ - 16/3.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.

Answer:
V ≈ 628.3 cm³Step-by-step explanation:
Volume of cylinder: V = π×r² × h
diameter = 20 cm ⇒ r = 10 cm
h = 2 cm
Volume:
V = π×(10)²×2 = 200π cm³ = 628.318.... cm³ ≈ 628.3 cm³
