An airplane takes off 200 yards in front of a 60 foot building. At what angle of elevation must the plane
take off in order to avoid crashing into the building?
Answer:
16.69°
Step-by-step explanation:
Given that,
Height of the building, h = 60 foot
Distance from the base of the building, b = 60 foot
We need to find the angle of elevation must the plane takes off in order to avoid crashing into the building. So,
[tex]\tan\theta=\dfrac{60}{200}\\\\\theta=\tan^{-1}\dfrac{60}{200}\\\\=16.69^{\circ}[/tex]
So, the required angle is 16.69°.

Answer:
145.83 kilómetros.
Step-by-step explanation:
Si un conductor llena su tanque con $600 y recorre 250 kilómetros, para determinar cuántos kilómetros podrá recorrer con $350 de combustible se debe realizar el siguiente cálculo:
600 = 250
350 = X
350 x 250 / 600 = X
87,500 / 600 = X
145.83 = X

what is the recursive formula of the geometric sequence 1/2,3/4,9/8,27/16
Answer:
Step-by-step explanation:
A recursive geometric formula has the pattern:
[tex]A_n=A_{n-1}*r[/tex] where r is the common ratio. Before we write the formula, we need to find the value for r. This r value has to be the same between each consecutive number in the series. Because it's geometric, r is multiplied in (whereas it's added in if the sequence is arithmetic). To get from 1/2 to 3/4 we find the r value in this way:
[tex]\frac{x}{2}=\frac{3}{4}[/tex] where x/2 is the same as 1/2 x. Cross multiply to get 4x = 6 and x = 3/2. That means that if r is 3/2, then we can multiply every term in that sequence by 3/2 to get to the next term in line. 3/4 times 32 is 9/8. Therefore, r = 3/2 and the formula will be:
[tex]A_n=A_{n-1}*\frac{3}{2}[/tex]

Parents of students at a middle school
were randomly selected to participate
in a survey. Forty-two out of 60 parents
who were surveyed support a proposal to
buy new computers. There are a total of
456 parents with students at the middle
school. Which is the best estimate of the
number of those parents likely to support
the new proposal?
A. 182
B. 319
C. 365
D. 438
Answer:
(B). 319
Step-by-step explanation:
[tex]\frac{42}{60}[/tex] = [tex]\frac{x}{456}[/tex]
[tex]\frac{7}{10}[/tex] = [tex]\frac{x}{456}[/tex]
x = [tex]\frac{7*456}{10}[/tex] ≈ 319
The best estimate of the number of those parents likely to support the new proposal is 319. So the option is (B) 319.
What is constant of proportionality?Firstly, there is proportional relationship.
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.
The constant k is called constant of proportionality.
Parents of students at a middle school were randomly selected to participate in a survey.
42 out of 60 parents who were surveyed support a proposal to buy new computers.
There are a total of 456 parents with students at the middle-school.
[tex]\dfrac{42}{60} = \dfrac{x}{456} \\\\\\x = \dfrac{42}{60} \times 456\\\\x = \dfrac{7}{10} \times 456\\\\x = 319[/tex]
Therefore, the best estimate of the number of those parents likely to support the new proposal is 319.

Michela is training for a race. She runs 5 miles in 52 minutes. Her goal is to run 6 miles in 1 hour. By how many minutes per mile must Michela decrease the rate to meet her goal? explain your reasoning.
Answer:
.4
Step-by-step explanation:
52/ /4= 10.4
60/6=10
10.4-10=.4
Michela needs to increase her speed by 0.23 miles/hour to attain her goal.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
She runs 5 miles in 52 minutes.
5 miles in (52/60) hour
In 1 hour → 5(60/52) = 300/52 = 5.769
Her goal was 6 miles in 1 hour.
5.769 + x = 6
x = 0.23 miles/hour
Hence "Michela needs to increase her speed by 0.23 miles/hour to attain her goal".

Step-by-step explanation:
. The London Eye is a popular tourist attraction in London, England and is one of the largest Ferris Wheels in the world. It has a diameter of 135 meters and makes one revolution (counterclockwise) every 30 minutes. It is constructed so that the lowest part of the Eye reaches ground level, enabling passengers to simply walk on to, and off of, the ride. Find a sinsuoid which models the height h of the passenger above the ground in meters t minutes after they board the Eye at ground level.
Answer:
[tex]y=-67.5[cos(\frac{\pi}{15}t)-1][/tex]
Step-by-step explanation:
We can start solving this problem by doing a drawing of London Eye. (See attached picture).
From the picture, we can see that the tourists will start at the lowest point of the trajectory, which means we can make use of a -cos function. So the function will have the following shape:
[tex]y=-Acos(\omega t)+b[/tex]
where:
A=amplitude
[tex]\omega[/tex] = angular speed.
t= time (in minutes)
b= vertical shift.
In this case:
A= radius = 67.5 m
[tex]\omega=2\pi f[/tex]
where the frequency is the number of revolutions it takes every minute, in this case:
[tex]f=\frac{1}{30} rev/min[/tex]
so:
[tex]\omega=2\pi (\frac{1}{30})[/tex]
[tex]\omega=\frac{\pi}{15} rad/min [/tex]
and
b= radius, so
b=A
b=67.5m
so we can now build our equation:
[tex]y=-67.5cos(\frac{\pi}{15} t)+67.5[/tex]
which can be factored to:
[tex]y=-67.5[cos(\frac{\pi}{15}t)-1][/tex]
You can see a graph of what the function looks like in the end on the attached picture.
The required sinusoidal equation is [tex]y = -67.5 (cos\dfrac{\pi t}{15} -1)[/tex]
Given that,
It has a diameter of 135 meters and makes one revolution (counterclockwise) every 30 minutes.
It is constructed so that the lowest part of the Eye reaches ground level, enabling passengers to simply walk on to, and off of, the ride.
We have to find,
A sinusoidal which models the height h of the passenger above the ground in meters t minutes after they board the Eye at ground level.
According to the question,
The tourists will start at the lowest point of the trajectory, which means we can make use of a -cos function. So the function will have the following shape:
[tex]y = -Acos(wt) + b[/tex]
Where, A=amplitude , [tex]\omega[/tex] = angular speed, t= time (in minutes) , b= vertical shift.
Then,
[tex]Radius = \dfrac{diameter}{2}\\\\Radius = \dfrac{135}{2}\\\\Radius = 65.5m[/tex]
The frequency is the number of revolutions it takes every minute is determined by the formula is,
[tex]\omega = 2\pi f[/tex]
Where,
[tex]f = \dfrac{1}{30} revolution \ per \ minute[/tex]
Then,
[tex]\omega = 2\pi \times \dfrac{1}{30}\\\\\omega = \dfrac{\pi }{15}\ radian \ per\ minute[/tex]
Here, The sinusoidal equation can be written as;
[tex]y = -67.5cos\dfrac{\pi t}{15} + 67.5\\\\y = -67.5 (cos\dfrac{\pi t}{15} -1)[/tex]
Hence, The required sinusoidal equation is [tex]y = -67.5 (cos\dfrac{\pi t}{15} -1)[/tex]

Step-by-step explanation:
A regular die has only 6 numbers: 1, 2, 3, 4, 5, & 6.
In those numbers, there are 3 odd numbers, and 3 even numbers. This would mean that the probability of getting an odd number would be 3/6.
But to simplify it, 3/6 ALSO equals 1/2
Answer:
1/2 is the answer
Step-by-step explanation:
A die has 6 possible outcomes: 1, 2, 3, 4, 5, 6
Out of these numbers 3 are odd numbers.
P(Event) = Number of favourable outcomes/ Total number of outcomes
P(odd) = 3/6

What is the equation of the line in slope-intercept form?
Answer:
y=-5x+6
Step-by-step explanation:
To find your slope (or m value), you must identify 2 points that your line crosses through (I used (1,1) and (0,6). You can either count up and over to the point (0,6) from (1,1), or you can use the formula y2-y1/x2-x1 (it would look like 6-1/0-1). This will give you -5 for your slope.
Your x-intercept (or b value) is 6 because you can see from the graph that that is where your line intercepts y.

Answer:

Step-by-step explanation:
The manufacturer of a drink wishes to compare the taste appeal of the standard formula (formula A) with that of a new formula (formula B). Each of the four judges is given three glasses in random order, two containing formula A and the other containing formula B. Each judge is asked to state which glass he or she most enjoyed. Suppose that the two formulas are equally attractive. Let Y be the number of judges stating a preference for the new formula. What is the distribution of Y
Answer:
P(y) = 4Cy * (2/3)^y * (1/3)^4-y
Step-by-step explanation:
Two distinguishable categories ; A and B ;
Number of cups of formula A given to each judge = 2
Number of cups of formula B given to each judge = 1
Total number of cups = 3
P(formula A) = 2/3
P(formula B) = 1/3
Hence, Probability of each of the two formulas is the same for each judge
Number of judges = 4
Each outcome is independent
y = Number of judges who prefer the new formula
Since, it meets all requirements for a binomial probability distribution :
Hence. The distribution of y ;
4Cy * p(A)^y * p(B)^4-y
P(y) = 4Cy * (2/3)^y * (1/3)^4-y
Find the equation of a line parallel to 3x-4y=24 that contains the point (-4,2).
