Answer:
56 feet
Step-by-step explanation:
This is a trigonometry problem. It makes use of tangent. You can take the tangent of an angle and it will equal the side opposite divided by the side adjacent that isn't the hypotenuse.
In this case the angle is 35 degrees.
Tangent of the angle = opposite/ adjacent side
Tan(35) = (x)/(80)
Tan(35) = 0.7 so
(0.7)= (X)/(80)
Using algebra each side can be multiplied by 80.
(80)(.7)=X
56=x
X is in feet, so X is equal to 56 feet.
Hope this helps!

what is the measurement of the third angle of a triangle if the other two angles each measures 45 degrees?
Answers
Answer: The answer is 90!
Step-by-step explanation:
A triangle's sides have to equal 180 degrees. The other two angles measure 45 degrees + 45 degrees, which equals 90. Now all you have to do is subtract 90 from 180. This equals 90, so the answer is 90 degrees.
Whenever you do problems like this in the future, remember these steps:
Angle 1 + Angle 2
180 - Combination of Angles 1 and 2 = Answer
The reason that you subtract from 180 degrees is because a straight angle is always 180 degrees. If you need more help with problems like these, I recommend watching some tutorials!

A component with time to failure T has failure rate z(t)= 2. 0*10-6 t/hour for t>0 1) Determine the probability that the component survives 200 hours 2) Determine the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours
Answers
The probability that the component survives 200 hours is approximately 0.9802. The probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, is approximately 0.8703.
What is probability?
Probability is a numerical representation of the likelihood or chance of a specific event occurring. It is typically expressed as a value between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain to occur.
To determine the probability that the component survives 200 hours, we need to calculate the survival function, which is the probability that the component lasts longer than 200 hours. We can use the formula:
[tex]$$ S(t) = e^{-\int_0^t z(u) du} $$[/tex]
where [tex]$S(t)$[/tex] is the survival function and [tex]$\int_0^t z(u) du$[/tex] is the integral of the failure rate from 0 to [tex]$t$[/tex].
In this case, the failure rate is [tex]$z(t) = 2.0\times10^{-6}t/\text{hour}$[/tex] for [tex]$t > 0$[/tex]. Integrating this from 0 to 200 gives:
[tex]$$ \int_0^{200} z(t) dt = \int_0^{200} (2.0\times10^{-6}t) dt =[/tex] [tex]\left[\frac{(2.0\times10^{-6})}{2}t^2\right]_0^{200} = 0.02 $$[/tex]
Substituting this into the survival function formula gives:
[tex]$$ S(200) = e^{-\int_0^{200} z(t) dt} = e^{-0.02} \approx 0.9802 $$[/tex]
Therefore, the probability that the component survives 200 hours is approximately 0.9802.
To determine the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, we need to use the conditional probability formula:
[tex]$ P(T > 400|T > 200) = \frac{P(T > 400 \cap T > 200)}{P(T > 200)} $$[/tex]
We can calculate the numerator using the survival function:
[tex]$ P(T > 400 \cap T > 200) = S(400) $$[/tex]
To find [tex]$S(400)$[/tex], we need to integrate the failure rate from 0 to 400:
[tex]$$ \int_0^{400} z(t) dt = \int_0^{400} (2.0\times10^{-6}t) dt = \left[\frac{(2.0\times10^{-6})}{2}t^2\right]_0^{400} = 0.16 $$[/tex]
Substituting this into the survival function formula gives:
[tex]$$ S(400) = e^{-\int_0^{400} z(t) dt} = e^{-0.16} \approx 0.8534 $$[/tex]
To find the denominator, we can use the survival function we found earlier:
[tex]$ P(T > 200) = S(200) = e^{-0.02} \approx 0.9802 $$[/tex]
Substituting these values into the conditional probability formula gives:
[tex]$ P(T > 400|T > 200) = \frac{S(400)}{S(200)} \approx \frac{0.8534}{0.9802} \approx 0.8703 $$[/tex]
Therefore, the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, is approximately 0.8703.
1) The probability that the component survives 200 hours is approximately 0.9802.
2) The probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, is approximately 0.8703.

y -intercept
oftheparabola y = x2 + 2x + 10
Answers
The y -intercept of the parabola y = x^2 + 2x + 10 is (0, 10)
the y-intercept represents the value of y when x=0. In the equation y = x^2 + 2x + 10, the x^2 and 2x terms create a parabola that opens upwards. As x approaches infinity or negative infinity, the value of y also increases towards infinity.
The y-intercept of a graph is the point at which the graph crosses the y-axis, which is where x=0. To find the y-intercept of the parabola y = x^2 + 2x + 10, we substitute x=0 into the equation, which gives
y = 0^2 + 2(0) + 10
y = 10
Therefore, the y-intercept of the parabola is (0, 10), which means the graph crosses the y-axis at the point (0, 10).

If we randomly choose three books, then the probability that the three we choose will consist of each of their favorite books is 0.000081.
The total number of books is = 43 books.
Now, 3 books have to be selected.
So, the number of ways of choosing 3 different books from the 43 books can be calculated as : ⁴³C₃ = 12341,
The number of ways that those 3 get their favourite book is = ³C₃ = 1.
The probability that 3 you choose will consist of each of their favorite books is = 1/12341

Graph the function by hand using the techniques you were taught in this unit: f(x) = 2sin(x)-2. Your work and explanations must use the methods taught in this class.
• Amplitude: 2
• Period: 2pi
• Midline: y = -2
• y-intercept: (0, -2)
Answers
To graph the function f(x) = 2sin(x)-2, we can start by plotting the y-intercept (0, -2).
Next, we can use the amplitude of 2 to mark the highest and lowest points of the graph. The highest point will be 2 units above the midline at y = 0, and the lowest point will be 2 units below the midline at y = -4.
To establish the period of the function, we need to identify the distance between one complete cycle of the graph. Since sine has a period of 2pi, we can see that the period of our function is also 2pi.
Starting from the y-intercept, we can mark a point on the graph that is one-quarter of the way through a cycle, at x = pi/2. The sine function will be at its maximum value of 1 at this point, so the graph will be at y = 0 + 2

Answers
You would need to make a 94 on the next quiz to have a mean quiz score of 90.
If 90 is the desired mean, then you have to multiply it by the number of quizzes
5 x 90 = 450 is the total in the 5 quizzes.
Now, add the scores of the first four quizzes.

Answers
(a) The predictor variable is Fall in feet and the response variable is Duration in seconds.
(b) The slope is in seconds per foot.
(c) The slope may be negative, as greater drop heights generally result in longer travel times.
(a) The predictor variable in this regression is Drop, which represents the drop height of the roller coaster, in feet, in feet. The response variable is Duration, which represents the duration of the trip, in seconds, in seconds.
(b) The units of slope in this regression are seconds per foot. This means that for each unit of increase in descent height in feet, the travel time will increase or decrease the value of the slope, measured in seconds per foot.
(c) The slope can be negative, as greater drop heights generally result in longer ride times, and the Tower of Terror roller coaster, which was exceptionally short despite its large drop height, has were removed from the analysis.
Therefore, the remaining 90 roller coasters in the dataset likely exhibit a negative relationship between drop height and time, meaning that as drop height increases, ride time decreases .
The Low R-value squared 29.4% means that the relationship between roller coaster drop and ride time in the data set is highly variable, but the negative slope indicates a general downward trend.

What is volume of cylinder?Two parallel circular bases joined by a curving lateral surface make up the three-dimensional geometric object known as a cylinder. The area of one of a cylinder's circular bases is multiplied by one of its heights to determine the cylinder's volume. In other words, V = πr²h, where V is the cylinder's volume, r is the circumference of one of its circular bases, and h is the cylinder's height.
The volume of the cylinder is given as:

Therefore the Surface Area of the rectangular prism is:
S.A. = 4A₁ + 2A₂
S.A. = 4(12) + 2(9)
= 48 + 18
= 66
Hence, the net surface area of the rectangular prism would be 66 meters sq.
A country road is 27 miles long and goes all the way around a lake, connecting the six cottages that are next to the lake. Two of the cottages are 1 mile apart (along the road). Two cottages are 2 miles apart, two are 3 miles apart, two are 4 miles apart, … two are 25 miles apart, and two are 26 miles apart. How are the cottages distributed along the road?
Answers
Using probability distribution, we can distribute the cottages as the follows along the road.
Define probability distribution?An experiment's potential outcomes are broken down into a probability distribution, which indicates the relative possibility of each one happening. For the purpose of describing a probability distribution, there are two key functions.
They are the cumulative distribution function and the probability density function, sometimes known as the probability mass function.
As the distance between each cottage and its neighbour is 1, 2, 3, 4, ... 25, or 26 miles, the entire length of the road that these distances occupy must equal 27 miles. The road links the six cottages, which explains why.
The cottages 1and 2 are separated by a mile, according to one conceivable distribution.
Similarly,
Two miles separate cottages 3 and 4.
Three miles separate cottages 5 and 6.
There are 4 miles between Cottages 1 and 3.
There are 5 miles between cottages 2 and 4.
There are 6 miles between cottages 3 and 5.
There are 7 miles between cottages 4 and 6.
Twenty-five miles separate cottages 1 and 6.
There are 26 miles between cottages 2 and 5.
By flipping the order of the cottage distances, a second potential distribution can be created. Which is:
There are 26 miles between cottages 2 and 5.
Twenty-five miles separate cottages 1 and 6.
There are 7 miles between cottages 4 and 6.
There are 6 miles between cottages 3 and 5.
There are 5 miles between cottages 2 and 4.
There are 4 miles between Cottages 1 and 3.
Three miles separate cottages 5 and 6.
Two miles separate cottages 3 and 4.
Two cottages 1 and 2 are one mile apart.
These two show that there are numerous ways to arrange the distances between the cottages while still adhering to the requirement that the distances must add to 27 miles, while there may be other alternative distributions.

They are the probability density function, also called the probability mass function, and the cumulative distribution function.
The total length of the road that these distances fill must be 27 miles because the distance between each cottage and its neighbor is 1, 2, 3, 4,... 25, or 26 miles. The six houses are connected by a road, which explains why.
According to one possible distribution, the distance between cottages 1 and 2 is one mile.
Similarly,
Cottages 3 and 4 are separated by two kilometers.
Cottages 5 and 6 are separated by three kilometers.
The distance between Cottages 1 and 3 is 4 kilometers.
The distance between houses 2 and 4 is 5 miles.
The distance between cottages 3 and 5 is six kilometers.
The distance between cottages 4 and 6 is seven kilometers.
The distance between houses 1 and 6 is 25 miles.
The distance between houses 2 and 5 is 26 miles.
It is possible to generate a second potential distribution by flipping the order of the cottage distances. That is:
The distance between houses 2 and 5 is 26 miles.
The distance between houses 1 and 6 is 25 miles.
The distance between cottages 4 and 6 is seven kilometers.
The distance between cottages 3 and 5 is six kilometers.
The distance between houses 2 and 4 is 5 miles.

what is 63.92/9.4 in long division explanation
Answers
In long division, 63.92/9.4 results with quotient of 6.8.
What is long division explanation?Long division is a method of dividing two numbers by repeatedly subtracting the divisor from the dividend and keeping track of the resulting quotient and remainder. This method is often used when dividing two numbers with several digits. The process of long division involves several steps that are repeated until there is no remainder left or until a desired level of precision is achieved.
In long division, the dividend is the number being divided, and the divisor is the number by which the dividend is being divided. The quotient is the result of the division, and the remainder is the amount left over after the division is complete.

cather added the ages of a crowd of 18 year olds and 22 year olds and got a sum of 290 if there were 10 18 year olds how many 22 year olds were in the crowd?
PLEASE HELP
Answers
Answer: 5
Step-by-step explanation:
If Cather added the ages of a crowd of both 18-year-olds and 22-year-olds and got 290, we can write that as 18x+22y=290. Knowing that there were 10 18-year-olds, we can plug 10 in for x.
18 times 10 + 22y = 290
So, first, we should multiply.
18 times 10 is 180, leaving us with 180+22y=290
Next, we should subtract both sides by 180.
So, 22y=110
Finally, we need to divide both sides by 22.
Leaving us with the answer of 5.
Answer:
5
Step-by-step explanation:
10×18=180
290-180=110
110/22=5
