Sketch the area represented by g(x). g(x)t4 dt Then find g'(x) in two of the following ways (a) by using Part 1 of the Fundamental Theorem g(x) (b) by evaluating the integral using Part 2 and then differentiating g'(x)
The area represented by g(x) is the definite integral of g(x) with respect to t from t=0 to t=x:
g(x) = ∫(t^4) dt from 0 to x
To find g'(x) using Part 1 of the Fundamental Theorem of Calculus, we know that:
g'(x) = d/dx (∫(t^4) dt from 0 to x) = (t^4) evaluated at x = x^4
To find g'(x) using Part 2 of the Fundamental Theorem of Calculus, we can evaluate the integral:
g(x) = ∫(t^4) dt = (1/5)t^5 evaluated from 0 to x = (1/5)x^5
then take the derivative of g(x) with respect to x:
g'(x) = d/dx ((1/5) x^5) = (1/5) * 5x^4 = x^4
Both ways give the same result of g'(x) = x^4

Many students choose to take courses in statistics and computer science as elective. Suppose that in a certain university 41% take computer science, 48% take statistics, and 63% take at least one of these two courses. What is the probability a randomly selected student takes both a computer science and a statistics courses as elective? Round your answer to two decimal places.
The probability that a randomly selected student takes both computer science and statistics courses as electives is 0.26
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
We can use the formula for the probability of the intersection of two events:
P(A and B) = P(A) + P(B) - P(A or B)
where A and B are the events of taking computer science and statistics courses as electives, respectively.
Given:
P(A) = 0.41 (probability of taking computer science)
P(B) = 0.48 (probability of taking statistics)
P(A or B) = 0.63 (probability of taking at least one of these two courses)
So,
P(A and B) = 0.41 + 0.48 - 0.63 = 0.26
Therefore, the probability is 0.26, rounded to two decimal places.

Find the centroid of the region in the first quadrant bounded by the x-axis, the parabola y2=8x , and the line x+y=6.
Coordinates of the centroid are (_,_).
The centroid of the region is (3,1).
The centroid of a region is a point that is the average of all the vertices of the region. In other words, it is the point that is the center of mass of the region. To find the centroid of a region, we need to find the x and y coordinates of the vertices of the region and then take the average of these coordinates.
To find the centroid of the region in the first quadrant bounded by the x-axis, the parabola y^2 = 8x, and the line x + y = 6, we need to find the x and y coordinates of the vertices of the region.
The parabola y^2 = 8x and the line x + y = 6 are the equations of the boundaries of the region. We can find the vertices of the region by solving for the points where these two equations intersect.
The parabola y^2 = 8x can be rewritten as y = ±√8x. So the x-coordinate of the vertex of the parabola is (3,3).
The line x + y = 6 can be rewritten as y = -x + 6. So the x-coordinate of the vertex of the line is (0,6) and (6,0).
So the three vertices of the region are (0,0), (3,3), and (6,0).
To find the x-coordinate of the centroid, we take the average of the x-coordinates of the vertices: (0 + 3 + 6)/3 = 3To find the y-coordinate of the centroid, we take the average of the y-coordinates of the vertices: (0 + 3 + 0)/3 = 1So the centroid of the region is (3,1).

The table shows monthly costs for two different internet service providers. What will be the difference in cost of the two plans after 18 months
Answer: 240
Step-by-step explanation:
The difference in cost between the two plans after 18 months is $240.
This is because the cost of Company A is consistently $35 more per month than that of Company B, which therefore would add up to $630 after 18 months.
The linear equation representing the cost of Company A is Y = 35X + 40, while the linear equation representing the cost of Company B is Y = 50X.
After 18 months, X would equal 18, and substituting this value into the two equations, we get the following for Company A:
Y = 35X + 40 Y = 35 * 18 + 40 Y = 630Meanwhile, for Company B, we get:
Y = 50X Y = 50 * 18 Y = 900The difference between these two values for different internet service providers is:
= $900 - $630 = $240This question should be provided with this following data:

Every variable's degrees are listed in descending order in the general form of any equation. The formula for a linear equation is x + b = 0.
given
Now solve any problem for one variable. In the first equation, I'll find the value of x:
200mph = p - w
On both sides, add w:
p = 200mph Plus w
Now that we have the x from the first equation, we can use it to solve for w in the second equation:
200 mph + w + w Equals 300 mph
Add related phrases together for 300 mph: 200 mph plus two
200 mph on both sides are subtracted:
100mph = 2w
50 mph divided by two is w.
Therefore, the wind's speed is 50 mph.
To find the plane's speed, enter the value we just discovered back into either equation. I'll enter it into the first equation.
200 mph = (p - 50 mph)
50 mph extra on both sides
250mph = p

x = (-b (b2 - 4ac))/2a to get the roots of the problem.
Quadratic equations: what are they?Just using equations x = ax2 + bx + c = 0 and a 0, a quadratic function is a 2nd polynomial problem in one variable. It is a third polynomial problem, hence the foundational theorem of algebra guarantees that there is least one solution. There may also be real or sophisticated solutions. The quadratic formula makes solving any quadratic equation easier for us. In order to solve this equation, we must first change its form to appear as ax2+bx+c=0, in which a, b, and d are the coefficients. Therefore, we add these coefficients to the method: (-b(b2-4ac))/ (2a).
Here,
The problem ax2 + bx + c = 0 can be solved using
the method x = (-b (b2 - 4ac))/2a to get the roots of the problem.
D = b² - 4ac provides the discriminant value. If D > 0, the equation has two genuine, separate roots.

To find the approximate difference in the percentage of people that liked pepperoni on their pizza and the percentage of people that only liked cheese pizza, we need to find the percentage of people that liked pepperoni and the percentage of people that only liked cheese, and then subtract the smaller percentage from the larger percentage.
From the graph, we can see that 30 people liked pepperoni, 20 people liked mushrooms, 15 people liked sausage, and 10 people liked cheese and olives.
The total number of people Jimmy asked is 30+20+15+10 = 75
The percentage of people that liked pepperoni is 30/75*100 = 40%
The percentage of people that only liked cheese is 10/75*100 = 13.33%
The difference between 40 and 13.33 is 26.67%.
So, the approximate difference in the percentage of people that liked pepperoni on their pizza and the percentage of people that only liked cheese pizza is 26.67%.

What is the function notation?
Function notation is a way of writing mathematical functions using a specific syntax. A function is a rule that assigns a unique output to each input. In function notation, the function is represented by a letter, usually f, g, or h, followed by a variable in parentheses.
To find (f g)(x), we first need to find g(x) by substituting the value of x into the equation for g(x) = x^2 - 7:
g(x) = x^2 - 7
Next, we substitute the result of g(x) into the equation for f(x) = 2x + 1:
(f g)(x) = f(g(x)) = f(x^2 - 7) = 2(x^2 - 7) + 1
So the final result is (f g)(x) = 2x^2 - 14 + 1 = 2x^2 - 13

What does the term function refer to?The study of numbers, their variations, mathematics and the regional tissue, structures, and both their actual and imagined locations, is known as mathematics. A function is a mathematical representation of the relationship between a set of inputs, each of which has an associated output. A function is a group of inputs that, when combined, result in a single, recognized output for each input. Each equation function is given a city, town, or scope, which is frequently referred to as a realm. Functions are typically denoted by the letter f. (x).
Here,
given:
g(x)=x²-2
h(x) = 2x + 3
To find : (5g -2h)(x)
So,
5g(x) = 5x²-10
and
2h(x) = 4x + 6
=> (5g -2h)(x) = 5x²-10 - 4x -6
=> (5g -2h)(x) = 5x² -4x -16
Therefore , the solution of the given problem of function comes out to be (5g -2h)(x) = 5x² -4x -16 .

Xochitl went into a movie theater and bought 6 bags of popcorn and 4 drinks, costing a total of $65. Alonso went into the same movie theater and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50. Determine the price of each bag of popcorn and the price of each drink.
The price of each bag of popcorn and the price of each drink is $7.5 and $4 respectively.
How to calculate the equation?Let the drinks be represented as d.
Let the popcorn be represented as p.
From the information, Xochitl went into a movie theater and bought 6 bags of popcorn and 4 drinks, costing a total of $65. Thus will be:
6p + 4d = 65
Alonso went into the same movie theater and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50. This will be:
9p + 8d = 107.50
Equating the equation
6p + 4d = 65 ..... i
9p + 8d = 107.50 ..... ii
Multiply equation i by 8
Multiply equation ii by 4
48p + 32d = 520
36p + 32d = 430
12p = 90
Divide
p = 90/12
= 7.5
6p + 4d = 65 .
6(7.5) + 4d = 65
4d = 65 - 45
4d = 20
d = 20/4
drink = 5
