A lighthouse is located on an island 33 miles from the closest point on a straight shoreline. If the lighthouse light rotates clockwise at a constant rate of 99 revolutions per minute, how fast does the beam of light move towards the point on the shore closest to the island when it is 5252 miles from that point
Question:
A lighthouse is located on an island 3 miles from the closest point on a straight shoreline. If the lighthouse light rotates clockwise at a constant rate of 9 revolutions per minute, how fast does the beam of light move towards the point on the shore closest to the island when it is 52 miles from that point
Answer:
The beam of light moves at [tex]16278\pi[/tex] miles/min
Step-by-step explanation:
This question is illustrated with the attached image
Taking the instructions in the question, one at a time.
A revolution of 9 per minute implies that:
[tex]\frac{d\theta}{dt} = \frac{9 * 2\pi\ rad}{1\ min}[/tex]
[tex]\frac{d\theta}{dt} = 18\pi \frac{rad}{min}[/tex]
Take tan of the angle in the attachment:
[tex]tan(\theta) =\frac{52}{3}[/tex]
Differentiate both sides with respect to time
[tex]\frac{d\ tan(\theta)}{dt} =\frac{52}{3} * \frac{dx}{dt}[/tex]
Rewrite as:
[tex]\frac{d\ tan(\theta)}{d\theta} * \frac{d\theta}{dt} =\frac{52}{3} * \frac{dx}{dt}[/tex]
In calculus:
[tex]sec^2(\theta) =\frac{d\ tan(\theta)}{d\theta}[/tex] -- Chain rule
So:
[tex]sec^2(\theta) *\frac{d\theta}{dt} =\frac{52}{3} * \frac{dx}{dt}[/tex]
In trigonometry:
[tex]sec^2(\theta) = tan^2(\theta) + 1[/tex]
So:
[tex](tan^2(\theta) + 1)\frac{d\theta}{dt} =\frac{52}{3} * \frac{dx}{dt}[/tex]
Recall that:
[tex]tan(\theta) =\frac{x}{3}[/tex]
[tex]((\frac{52}{3})^2 + 1)\frac{d\theta}{dt} =\frac{1}{3} * \frac{dx}{dt}[/tex]
[tex](\frac{52^2}{9} + 1)\frac{d\theta}{dt} =\frac{1}{3} * \frac{dx}{dt}[/tex]
[tex](\frac{2704}{9} + 1)\frac{d\theta}{dt} =\frac{1}{3} * \frac{dx}{dt}[/tex]
[tex](\frac{2704+9}{9})\frac{d\theta}{dt} =\frac{1}{3} * \frac{dx}{dt}[/tex]
[tex](\frac{2713}{9})\frac{d\theta}{dt} =\frac{1}{3} * \frac{dx}{dt}[/tex]
Recall that: [tex]\frac{d\theta}{dt} = 18\pi \frac{rad}{min}[/tex]
[tex](\frac{2713}{9}) * 18\pi =\frac{1}{3} * \frac{dx}{dt}[/tex]
[tex]2713 * 2\pi =\frac{1}{3} * \frac{dx}{dt}[/tex]
Multiply both sides by 3
[tex]3 * 2713 * 2\pi =\frac{1}{3} * \frac{dx}{dt} * 3[/tex]
[tex]3 * 2713 * 2\pi =\frac{dx}{dt}[/tex]
[tex]16278\pi =\frac{dx}{dt}[/tex]
[tex]\frac{dx}{dt} = 16278\pi[/tex] miles/min
Hence:
The beam of light moves at [tex]16278\pi[/tex] miles/min

What is 22/35 as a percent
Answer:
62.857142857143%
Step-by-step explanation:
5 more than a number m equals 8
Answer: m=3
Step-by-step explanation:
This could be written as m+5=8
You would then do the inverse to 'undo' the equation. So instead of adding 5 you would take away 5 from 8.
8-5=3

Answer:
Just multiply 9.6*4.9 which is 47.04 m^2.
You can basically cut the shape in half, then put the shapes back together to look like a rectangle. The area formula is bh, or 9.6*4.9. Ignore the 11 m.
Jason buys a plot of land that is 2/5 of an acre in size. Ava buys a
plot of land that is 2/8 of an acre in size. Whose plot of land is
smaller?
Answer:
Ava's
Step-by-step explanation:
To find whose plot of land is smaller, compare the sizes of their plots.
Jason's is 2/5 of an acre, while Ava's is 2/8 of an acre.
Because they have the same numerator, we can look at the denominator to see which is smaller.
The number with the larger denominator will be smaller. So, this means 2/8 is smaller than 2/5.
So, Ava's plot of land is smaller

Explain the inequality -4 C > -9C describes how the temperatures are related
NO SPEAK ENGLISH SORRYYYY
The inequality explains the value of -4°C is greater than -9°C
What is inequality?It is known as inequality when both sides of a mathematical statement contain mathematical signs that are either less than or larger than one another.
It is given that,
-4°C > -9°C
We utilize the "Greater than or equal to" sign in linear inequalities when the value of a variable is greater than or equal to a certain value. The "greater than" symbol (>), which has a sleeping line beneath it, is used to denote it. It is represented by the character (≥).
Thus, the inequality explains the value of -4°C is greater than -9°C.

True or false?is the point(16,4) included in this function: Y=2x or Y=x2 or y= x+12 or y=x-12
Answer:
True
Step-by-step explanation:
It is true because the graph of [tex]y=x-12[/tex] passes through the point [tex](16,4)[/tex]
x = 16
y = 4
Substitute
4 = 16 - 12
4 = 4
Therefore, the answer is true.

c. A parabola and a circle
d. A parabola and the hyperbola y = 1/x
Answer:
c) parabola and circle: 0, 1, 2, 3, 4 times
d) parabola and hyperbola: 1, 2, 3 times
Step-by-step explanation:
c. A parabola can miss a circle, be tangent to it in 1 or 2 places, intersect it 2 places and be tangent at a 3rd, or intersect in 4 places.
__
d. A parabola must intersect a hyperbola in at least one place, but cannot intersect in more than 3 places. If the parabola is tangent to the hyperbola, the number of intersections will be 2.
If the parabola or the hyperbola are "off-axis", then the number of intersections may be 0 or 4 as well. Those cases seem to be excluded in this problem statement.
