The intervals can be written as (-∞, 4) and (4, ∞) for increasing, and [4, 4] for decreasing.
The function h(x) = (x - 4)² - 3x + 7 is a parabolic function that opens upwards.
The function has a critical point at x = 4, where it changes direction from decreasing to increasing.
To determine the intervals on which the function is increasing or decreasing, we need to look at the sign of the first derivative of the function, which will tell us if the function is increasing or decreasing at any given x value.
In this case, the derivative of
=> h(x) = 2(x - 4) - 3.
Setting this equal to zero and solving for x, we find that x = 4 is the only critical point.
The second derivative of h(x) is 2, which is positive.
This tells us that the first derivative is increasing, which means the original function is increasing.
Therefore, the intervals on which the function is increasing are all x values greater than 4 or all x values less than 4. The intervals on which the function is decreasing are all x values between 4 and 4.

The complete answers regarding flow of people and occupancy are solved as follows:
(a) The flow of people from downtown to campus is the rate at which the shuttle buses can transport passengers from the downtown bus stop to the campus bus stop.
(b) The flow of people from campus to downtown is equal to the rate at which passengers are coming to the campus bus stop.
(c) The average bus occupancy from campus to downtown is equal to the number of passengers on each bus divided by the number of seats on each bus.
Dispatching the buses from downtown to campus at equal headways would reduce the average waiting time of passengers going from campus to downtown. This is because the slower bus would have more time to pick up and drop off passengers, and the faster bus would not be slowed down by having to wait for the slower bus. The overall result would be a reduction in the average waiting time for all passengers.

an aircraft seam requires 23 rivets. the seam will have to be reworked if any of these rivets is defective. suppose rivets are defective independently of one another, each with the same probability. (round your answers to four decimal places.) (a) if 20% of all seams need reworking, what is the probability that a rivet is defective? (b) how small should the probability of a defective rivet be to ensure that only 11% of all seams need reworking?
The probability that a rivet is defective if 20% of all seams need reworking is 1- (0.8)^(1/23), and the probability of a defective rivet be to ensure that only 11% of all seams need reworking is 1- (0.89)^(1/23).
This is based on the probability of independence events using the axiomatic probability approach.
Let the probability of a defective rivet be p, so the probability of the rivet not being defective is given by = 1-p.
So, the probability that all the rivets are defective is given by p^23 since, all the rivets are independently defective , and for independence of events A and B , probability of occurrence of A and B together is given by P(A).P(B).
So, the probability that none of the rivet is defective = (1-p)^23.
Now, the probability that at least one rivet is defective, is given by 1-P(none of the rivet is defective) = 1- P(none of the rivets are defective)
= 1-[(1-p)^23].
Now, its given that the seam needs to be reworked if there is at least one defective rivet.
So, in (a), P(seam to be reworked)= 1-[(1-p)^23] = 0.2
(1-p)^23=0.8
1-p=(0.8)^(1/23)
p= 1- (0.8)^(1/23).
For part (b), P(seam to be reworked)= 1-[(1-p)^23] = 0.11
(1-p)^23=0.89
1-p=(0.89)^(1/23)
p= 1- (0.89)^(1/23).

5. Mr. Muscles loads up a bar with 910 newtons (~205 lbs) of weight and pushes the
bar up over his head eight times. Each time he lifts the weight .5 meters. How much
work did he do If he does the whole thing in 15 seconds, how much power did it
take? SHOW YOUR WORK.
It took 245.33 watts of power to perform the work.
What is the work?
Work is defined as a force causing the movement or displacement of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force.
The work done by Mr. Muscles can be calculated as follows:
Work = Force x Distance x Cos(θ)
where Force is 910 N, Distance is 4 m (since he lifts the weight 0.5 m 8 times), and θ is the angle between the force applied and the displacement of the weight, which is assumed to be 0° in this case since the weight is being lifted straight up.
Work = 910 N * 4 m * cos(0°) = 3640 N * m
The power required to perform this work in 15 seconds can be calculated as follows:
Power = Work / Time
Power = 3640 N * m / 15 s = 245.33 W
hence, it took 245.33 watts of power to perform the work.

let f be the function defined by f(x) = (x2 1)e-x for -4 less than or equal to x less than or equalto four.a) for what values of x does f reach its absolute maximum?
Consequently, the interval's leftmost extreme is f(-4) = 17e^{-4}, where the absolute maximum is located.
The function f is f(x) = [tex](x^2 + 1)e^{-x}[/tex]
First, solve the equation f'(x) = 0 to identify the critical locations. It will be calculated using the formula [tex]\frac{d}{dx}(xy) = x\frac{d}{dx}(y) + y\frac{d}{dx}(x)[/tex].
f'(x) = [tex](x^2 +1)\frac{d}{dx}e^{-x}+e^{-x} \frac{d}{dx}(x^2+1)[/tex]
f'(x) = [tex]-(x^2 + 1)e^{-x}+2xe^{-x}[/tex]
Simplifying
Taking e^{-x} common
f'(x) = [tex][2x-(x^2+1)]e^{-x}[/tex]
Solving the bracket
f'(x) = [tex]e^{-x}(-x^2+2x-1)[/tex]
Now equating f'(x) = 0, then
[tex]e^{-x}(-x^2+2x-1)[/tex] = 0
The only essential point is at x = 1 since e^{-x} is zero only at x = ∞.
f(1) = 2e^{-1}.
Then determine the value that defines the interval's extremes:
f(-4) = 17e^{-4}
The maximal candidate is f(-4) since it is the largest of all the candidates.

It is not possible to guarantee the exact number of points within a certain distance of each other in a square with 42 points placed inside.
Since the side length of the square is 2, the area of the square is 2 x 2 = 4. If 42 points are placed inside the square, the maximum distance between any two points will be equal to the diagonal of the square, which is equal to the square root of 2 times the side length of the square. The diagonal of the square is 2 * √(2), or approximately 2.82.
The number of points within a certain distance of each other depends on the size of the distance, as well as the density of the points in the square. However, it is not possible to guarantee that all 42 points will be within a certain distance of each other.

The value of the definite integral of f(x) over the interval [−1, 5] is estimated to be between 36 and 42.
What do you mean by function?A function is a mathematical concept that assigns a unique output value for each input value. It is a rule that takes in an input or set of inputs and maps it to a specific output. Functions are represented by symbols, usually denoted by a letter, such as "f".
In mathematical notation, a function is usually expressed as "f(x)" where "x" is the input and "f(x)" is the corresponding output. For example, a function could be defined as f(x) = x^2, which means that for any value of x, the function will calculate and return the square of that value.
Functions play a central role in mathematics and are used to model real-world phenomena and to study the relationships between variables. They are also used in computer programming to perform specific tasks, such as converting temperatures from Celsius to Fahrenheit or calculating the square root of a number.
Since 6≤f(x)≤7 for −1≤x≤5, we have a lower bound of 6 and an upper bound of 7 for the function over this interval. This means that, for any possible value of f(x) in the interval, we can use 6 as a lower estimate and 7 as an upper estimate for the definite integral. Hence, we have:
Lower estimate: ∫5−1 6 dx = 6(5 - (-1)) = 6(6) = 36
Upper estimate: ∫5−1 7 dx = 7(5 - (-1)) = 7(6) = 42

I need step by step answer of this question. Thank you
Step-by-step explanation:
For two triangles to be congruent, they either need to have three respectively equal sides (SSS), two respectively equal signs with the same angle between them (SAS), two same angles with a respectively equal side between them (ASA), or for a right-angled triangel, a respectively equal hypotenuse and side (RHS).
Here we have the triangles ΔABC and ΔCDE. We know DC is equal to BC because they are marked as such, same for AC and EC. We also know <ACB = <DCE because they are vertically opposite angles. Since we have two triangles with equal sides and the same angle between these sides (SAS), we can say these triangles are congruent.
a box has 4 green balls and 5 red balls. a number, i, is picked at random from {2,3,4,5}. then i balls are chosen at random from the box without replacement.
a) The probability that the 3 balls chosen were all green is 1/21.
b) The probability that all the balls are chosen is red is 1/252.
What is probability?
Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
(a) Given 3 balls were chosen at random without replacement, the probability that they were all green is given by:
P(green) = (number of favorable outcomes) / (number of total outcomes)
The number of favorable outcomes is the number of ways to choose 3 green balls out of 4, which is C(4,3) = 4.
The number of total outcomes is the number of ways to choose 3 balls out of 9, which is C(9,3) = 84.
So, the probability that 3 balls chosen were all green is:
P(green) = C(4,3) / C(9,3) = 4 / 84 = 1/21
(b) The probability that all the balls chosen are red is given by:
P(red) = (number of favorable outcomes) / (number of total outcomes)
The number of favorable outcomes is the number of ways to choose 5 red balls out of 5, which is C(5,5) = 1.
The number of total outcomes is the number of ways to choose 5 balls out of 9, which is C(9,5) = 126.
So, the probability that all the balls chosen are red is:
P(red) = C(5,5) / C(9,5) = 1 / 126 = 1/252
Hence,
a) The probability that the 3 balls chosen were all green is 1/21.
b) The probability that all the balls are chosen is red is 1/252.

What is the Meaning of Arc?
An arc in mathematics is a segment of a curve or a segment of a circle.
What is an arc?
A circle's arc is referred to as a portion or section of its circumference. A semicircular arc is one whose length is exactly half that of a circle.
The arc is represented by the letters ‘⌒’ or ‘⌢’ in Euclidean geometry.
There are two methods for measuring an arc which are:
1. Length of the arc
The length of the arc is calculated in units of distance, such as centimeters. The arc is preceded by the lowercase letter l (for "length") to identify it.
2. Angle of the arc
The angle of the arc is the angle that the arc at the centre of the circle subtends.
Hence, an arc in mathematics is a segment of a curve or a segment of a circle.

two sides of a triangle measure 9 units and 11 units. in units, what is the positive difference between the measures of the smallest and the largest possible integral lengths of the third side of the triangle?
The measures of the smallest and the largest possible integral lengths of the third side of the triangle is 21 and 1 respectively
What is Triangle?
A triangle is a three-edged polygon with three vertices. It is a fundamental shape in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.
A side of a triangle must be always less than or equal to the sum of other two sides and greater than the difference of other two sides.
Say the required side is x.
So x<9+11 and x>9-11
So 20<x<2
So the smallest integer is 21 and the largest integer is 1

what is the difference between constructing a regular hexagon and constructing an equilateral triangle? (1 point)
Answer: Your answer is A or
For the hexagon construction, every arc along the circle is connected, but for the equilateral triangle construction, every other arc along the circle is connected.
Step-by-step explanation: It makes sense because in the lesson you need to make 6 arcs for both hexagons and equilateral triangles. However hexagons have 2 times as much sides as triangles so to make a triangle you would have to make a line with every other arc. That means skip an arc each line you make. For A hexagon obviously because it has 6 sides you just draw the lines to connect all 6 arcs

you have 25 balls. 15 of them is black balls 10 of them is white. what is the probability to pick a white ball then a black ball
You have 25 balls, 15 of them is black balls 10 of them is white then the probability to pick a white ball then a black ball is 2/5.
We have total balls = 25
The number of white balls = 10
The number of black balls = 15
Simply put, probability measures how probable something is to occur. We can evaluate the probabilities of different scenarios, or even how likely they were, whenever we are uncertain of how an incident will turn out. Statistics is the study of events subject to probability.
The probability to pick a white ball then a black ball = The number of white balls/Total Balls
The probability to pick a white ball then a black ball = 10/25
The probability to pick a white ball then a black ball = 2/5
