Help with the calculus problem please
The area of the region is equal to the area under the curve y = cos(x) over the interval 0 ≤ x ≤ π/6, given by the integral
[tex]\displaystyle\int_0^{\frac\pi6}\cos(x)\,\mathrm dx = \sin(x)\bigg|_0^{\frac\pi6}=\sin\left(\frac\pi6\right)-\sin(0)=\boxed{\frac12}[/tex]
which follows from
• the fact that d/dx [sin(x)] = cos(x)
• the fundamental theorem of calculus
In a set of three lines, a pair of parallel lines is intersected by a transversal. The intersection forms eight special angles. Two of the special angles, A and B, are corresponding angles.
For the set of parallel lines intersected by a transversal, A=4x and B=-5(x-18).
Part A: Write an equation to represent the corresponding relationship betweenA andB.
Part B: Use the equation to find the measures of A and B.
Answer:
Part A: 4x = -5(x-18)
Part B: A and B both = 40 degrees
Step-by-step explanation:
Ok, corresponding angles are in the same position on the two parallel lines cut by the transversal. And they are equal in measure. So, upper right = upper right.
So A = B
4x = -5(x -18)
4x = -5x + 90
9x = 90
x = 10
Angle A = 4x = 40 degrees, which means angle B is also 40, but let's show the work:
Angle B = -5(x - 18) = -50 + 90 = 40

A cone has a diameter of 20cm and a height of 12cm, what is the volume of the cone?
Answer:
The cone volume that has a diameter of 20cm and a height of 12cm is 5,026.548246 cm^3 or 5,027 cm^3
Make sure to round your answer to the nearest significant figure that you're asked.
Step-by-step explanation:
The formula for the volume of a cone is (height x π x (diameter / 2)^2)/3, where (diameter / 2) is the radius of the base (d - 2 x r), so another way to write it is (height x π x radius^2) / 3

180-104 is 76 76-10=66 66/2 is 33
Answer: x = 33
Step-by-step explanation:
Well since that line is basically equal to 180 all you have to do is plug in those numbers for x. Since 33 + 10 = 43 Alll you gotta do is add that up. So we have 104 + 33 + 43 = 180. I’m not the best at explaining things but I hope this helped :)

How much must be deposited today into the following account in order to have get 35,000 in 5 Years
An account with monthly compounding and an APR of 4%
should be deposited today.
(Do not round until the final answer. Then round to the nearest cent as needed)
Answer:
$ 28,665.11 must be deposited today into the account.
Step-by-step explanation:
Given that there is an account with monthly compounding and an APR of 4%, to determine how much must be deposited today into the following account in order to have $ 35,000 in 5 years, the following calculation must be performed:
X x (1 + 4/12) ^ 5x12 = 35,000
X x (1 + 0.333) ^ 60 = 35,000
X x (1,333) ^ 60 = 35,000
X x 1.220999 = 35,000
X = 35,000 / 1.22099
X = 28,665.11
Thus, $ 28,665.11 must be deposited today into the account.
g During winter, red foxes hunt small rodents by jumping into thick snow cover, without any visual clue. Researchers examined the compass direction of hundreds of such jumps. They found that 73% of jumps in the northeast direction were successful, compared with 60% of jumps in the southwest direction and only 18% of jumps in all other directions. True or False: Jumping direction and jump outcome are independent.
Answer: False
Step-by-step explanation:
Events can be classed as being dependent or independent depending on whether the outcome of a certain event affects the outcome of another. In the scenario above, the success rate of jumps in the Northeast direction is higher than in the southwest direction and even much than in other directions. With these uneven rate of success, the probability that a fox will have a successful jump will depend on the direction in which the fox is jumping. With an high expected success probability in the Northeast and southwest than in other directions
On a coordinate plane, solid circles appear at the following points: (negative 3, 2), (negative 3, 3), (1, 4), (1, negative 4), (2, negative 4), (2, negative 2).
How many points need to be removed from this graph so that it will be a function?
1 point
2 points
3 points
4 points
Answer:
3 points
Step-by-step explanation:
A function is a relation that maps elements of a set for the inputs (the domain, usually denoted with the variable x) into elements of another set, the set of the outputs (the range, usually denoted with the variable y).
So the relation can be represented with points (x, y), which means that point x is being mapped into point y.
Such that the needed condition is that each element of the domain is mapped into only one element in the domain.
So for example, if for a relationship we have the points (a, b) and (a, c)
The point a is being mapped into two different outputs.
Now let's go to our problem, we have the points:
(-3, 2), (-3, 3), (1, 4), (1, -4), (2, -4), (2, -2)
If we have repeated inputs, we need to remove points until we have one of each.
We can see that the inputs -3, 1, and 2 are repeated one time.
Then we need to remove one of each, for example if we remove the second, fourth and sixth points, the set becomes:
(-3, 2), (1, 4), and (2, -4)
This is a function.
Then we need to remove 3 points.

On a survey, 3 out of every 8 band members prefer listening to jazz music. Based on the survey, how many out of 240 band members would prefer listening to jazz music
Answer:
90
Step-by-step explanation:
Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
Vertical/ x = 25.
Step-by-step explanation:
Vertical angles are self-explanatory; vertical angles are angles that are vertical from each other.
Vertical angles are also congruent (equal), meaning that both angles equal 75°.
4x - 25 = 75.
To solve this expression, we must first add 25 to 75. This is because there is a subtraction sign in front of 25, so we must do the opposite.
25 + 75 = 100
Lastly, divide 100 from 4.
4x = 100
100 / 4 = 25
x = 25
10. What value of x and y will make the polygon a
parallelogram?
Answer:
Step-by-step explanation:
20 = 5y
4=y
x+3y = 2(x+y-1)
x+3y = 2x +2y -2
x+3(4) = 2x + 2(4) -2
x +12 = 2x +8 -2
12-8+2 = 2x -x
6 =x
The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal, and opposite angles equal.
Given is a polygon,
We know opposite sides of a parallelogram are equal,
Therefore,
5y = 20
y = 20/5
y = 4
And,
Putting y = 4, in x+3y = 2(x+y-1)
x+12 = 2(x+3)
x+12 = 2x+6
x = 12-6
x = 6
Hence, The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.

which of the following best describes the slope of line LP?
A) 5/2
B) 2
C) 2/5
D) 1/3
===========================================================
Explanation:
Point L is located at (-8, 1) while P is at the point (7,7)
Let's apply the slope formula for these two points
m = (y2-y1)/(x2-x1)
m = (7-1)/(7-(-8))
m = (7-1)/(7+8)
m = 6/15
m = (3*2)/(3*5)
m = 2/5 is the slope of line LP
A slope of 2/5 means that each time you go up vertically 2 units (rise), you move to the right 5 units (run). In short, it's "up 2, over to the right 5". A positive slope means we move upward as we move from left to right.

Question Completion:
California (population about 40 million) has about twice as many people as New York State (population about 20 million). Without calculation, pick the correct option and explain your choice.
If the underlying population SDs are equal, a simple random sample of 1000 people in California is
(i) about half as accurate
(ii) about 1/V2 times as accurate
(iii) about as accurate
(iv) about V2 times as accurate
(v) about twice as accurate
as a simple random sample of 1000 people in New York State.
Answer:
If the underlying population SDs are equal, a simple random sample of 1000 people in California is
(i) about half as accurate
as a simple random sample of 1000 people in New York State.
Step-by-step explanation:
Since the population of California is about 40 million, which is twice as many people as in New York State (approximately 20 million), in taking a sample size, that of California supposed to be as twice as New York's.
Therefore, if the random sample of 1,000 people is taken from California, just as a random sample of 1,000 people is also taken from New York State, we can conclude that the accuracy of population standard deviation of California will be about half as accurate as the standard deviation of New York's population.
This is because accuracy is enhanced by a larger sample size. This means that if the sample size of California is 2,000, the SD would have been equally as accurate as New York's.
