c. [-1,1]
"
Answers
The absolute maximum value of f(x) on the interval [-1,1] is f(-1) = 10, and the absolute minimum value is f(3) = -4.
To find the absolute maximum and minimum values of the function f(x) = x^4 - 4x^3 + 5 on the given intervals, we need to find the critical points and the endpoints of each interval, and then evaluate the function at these points to determine which one gives the maximum or minimum value.
a. [-1,2]
The critical points of f(x) occur where f'(x) = 0 or where f'(x) does not exist. We have:
f(x) = x^4 - 4x^3 + 5
f'(x) = 4x^3 - 12x^2
f''(x) = 12x^2 - 24x
Setting f'(x) = 0, we get:
4x^3 - 12x^2 = 0
4x^2(x - 3) = 0
x = 0, 3
We also have f''(0) = 0 and f''(3) = 18, so x = 0 is a point of inflection and x = 3 is a local minimum.
Evaluating f(x) at the endpoints and critical points, we get:
f(-1) = 11
f(0) = 5
f(2) = 5
f(3) = -4
Therefore, the absolute maximum value of f(x) on the interval [-1,2] is f(-1) = 11, and the absolute minimum value is f(3) = -4.
b. [0,4]
The critical points of f(x) occur where f'(x) = 0 or where f'(x) does not exist. We have:
f(x) = x^4 - 4x^3 + 5
f'(x) = 4x^3 - 12x^2
f''(x) = 12x^2 - 24x
Setting f'(x) = 0, we get:
4x^3 - 12x^2 = 0
4x^2(x - 3) = 0
x = 0, 3
We also have f''(0) = 0 and f''(3) = 18, so x = 0 is a point of inflection and x = 3 is a local minimum.
Evaluating f(x) at the endpoints and critical points, we get:
f(0) = 5
f(4) = 69
f(3) = -4
Therefore, the absolute maximum value of f(x) on the interval [0,4] is f(4) = 69, and the absolute minimum value is f(3) = -4.
c. [-1,1]
The critical points of f(x) occur where f'(x) = 0 or where f'(x) does not exist. We have:
f(x) = x^4 - 4x^3 + 5
f'(x) = 4x^3 - 12x^2
f''(x) = 12x^2 - 24x
Setting f'(x) = 0, we get:
4x^3 - 12x^2 = 0
4x^2(x - 3) = 0
x = 0, 3
We also have f''(0) = 0 and f''(3) = 18, so x = 0 is a point of inflection and x = 3 is a local minimum.
Evaluating f(x) at the endpoints and critical points, we get:
f(-1) = 10
f(0) = 5
f(1) = 2
f(3) = -4
Therefore, the absolute maximum value of f(x) on the interval [-1,1] is f(-1) = 10, and the absolute minimum value is f(3) = -4.

What is the maximum likelihood estimate for the bias of this coin (p(heads))?Since you're estimating the bias of a coin that came up heads 10 times and tails 20 times, to find the maximum likelihood estimate for the bias of this coin (p(heads)), we use a binomial probability
What is a binoimial probability?
A binomial probability is the probability of events that can have only two possible outcomes.
It is given by P(X = x) = ⁿCₓpˣqⁿ⁻ˣ where
n = total number of trials, x = number of required trials, p = probability of successes and q = probability of failuresGiven that the bias of a coin that came up heads 10 times and tails 20 times, we have that
n = 10 + 20 = 30, x = 10 (maximum number of heads) and p = q = 1/2(since it is a biased coin and has only two possible outcomes)So, to get the maximum likelihood estimate for the bias of this coin (p(heads)), we substitute the values of the variables into the equation, So,
p(heads) = P(X = x) = ⁿCₓpˣqⁿ⁻ˣ
P(X = 10) = ³⁰C₁₀p¹⁰q³⁰⁻¹⁰
= ³⁰C₁₀p¹⁰q²⁰
= ³⁰C₁₀(1/2)¹⁰(1/2)²⁰
= ³⁰C₁₀(1/2)³⁰
= 30045015 (1/2)³⁰
= 0.027982

Remy wanted to measure the angle of the slide in the playground. He used a piece of folded paper that was 10°. He measured that 3 of the folded paper angles would fit in the angle made by the slide. What was the angle of the slide?
Answers
Answer:
30°

Since the folded paper can fit into the slide three times, we simply have to multiply 10° by 3:
10° * 3 = 30°

A pool measuring 12 meters by 22 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 936 square meters. What is the width of the path?
Answers
The width of the path is 1 meter. This makes the length of the pool including the path 14 meters and the width 24 meters,
Let's denote the width of the path as x. Then the length of the pool including the path is 12 + 2x meters and the width is 22 + 2x meters. The total area of the pool and the path combined is given as 936 square meters, so we can set up an equation:
(12 + 2x)(22 + 2x) = 936
Simplifying this equation, we get:
4x^2 + 68x - 72 = 0
Factoring this quadratic equation, we get:
(x + 9)(4x - 8) = 0
Since the width of the path cannot be negative, we can only consider the positive root, which is: x = 2
Therefore, the width of the path is 2 meters.
But wait, this is not the final answer! We need to remember that the width of the path is uniform, which means it is the same on all sides of the pool.
If the width of the path is 2 meters, then the length of the pool including the path is 16 meters and the width is 26 meters. This gives a total area of: 16 x 26 = 416 square meters
which is clearly less than 936 square meters. Therefore, we made a mistake in our calculation and the width of the path cannot be 2 meters.
Let's go back to our quadratic equation and solve for x again: 4x^2 + 68x - 72 = 0
Dividing both sides by 4, we get:
x^2 + 17x - 18 = 0
Factoring this quadratic equation, we get:
(x + 18)(x - 1) = 0
Again, we can only consider the positive root, which is:
x = 1
Therefore, the width of the path is 1 meter. This makes the length of the pool including the path 14 meters and the width 24 meters, giving a total area of: 14 x 24 = 336 + 600 = 936 square meters, which confirms that our solution is correct.

a sample of 224 students showed that they attend an average of 2.6 school athletic events per year with a standard deviation of 0.8. determine a 90% confidence interval for the population mean
Answers
We can say with 90% confidence that the population mean of school athletic events attended by students is between 2.485 and 2.715.
To determine the 90% confidence interval for the population mean, we need to use the formula:
CI = x ± Z(α/2) × (σ/√n)
Where:
x = sample mean = 2.6
σ = sample standard deviation = 0.8
n = sample size = 224
α = significance level = 1 - 0.90 = 0.10 (since we want a 90% confidence level)
Z(α/2) = the critical value from the standard normal distribution table, which corresponds to the significance level. For a 90% confidence level, Z(0.05) = 1.645.
Plugging in the values, we get:
CI = 2.6 ± 1.645 × (0.8/√224)
CI = 2.6 ± 0.115
CI = (2.485, 2.715)

use green's theorem to find the counterclockwise circulation and outward flux for the field f=(7x−4y)i (9y−4x)j and curve c: the square bounded by x=0, x=4, y=0, y=4.
Answers
The counterclockwise circulation around c is 12 and the outward flux through c is zero.
Green's theorem is a useful tool for calculating the circulation and flux of a vector field around a closed curve in two-dimensional space.
In this case,
we have a field f=(7x−4y)i+(9y−4x)j and
a square curve c bounded by x=0, x=4, y=0, y=4.
To find the counterclockwise circulation, we can use the line integral of f along c, which is equal to the double integral of the curl of f over the region enclosed by c.
The curl of f is given by (0,0,3), so the line integral evaluates to 12.
To find the outward flux, we can use the double integral of the divergence of f over the same region, which is equal to zero since the divergence of f is also zero.

Answers
The graph of the equation y = 7x + 1 can be hand-drawn or sketched to visualize its shape and key values. It is a straight line with a slope of 7 and a y-intercept of 1.
To hand-draw or sketch the graph of the equation y = 7x + 1, we can start by plotting a few key points on the Cartesian plane. Since the equation is in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we know that the line will have a slope of 7 and will intersect the y-axis at the point (0, 1).
From the y-intercept (0, 1), we can use the slope of 7 to find additional points on the line. For example, if we move one unit to the right (x = 1), we will move 7 units upward (y = 8). Similarly, moving two units to the right (x = 2) will result in moving 14 units upward (y = 15).
By connecting these points on the Cartesian plane, we can sketch a straight line that represents the graph of the equation y = 7x + 1. The slope of 7 indicates that the line has a constant steepness, and the y-intercept of 1 shows where the line intersects the y-axis. This hand-drawn or sketched graph helps us visualize the relationship between x and y values in the given equation.

How much money she makes from the 15 bracelets:
4.65 x 15= $69.75
Answer:
Part 1: 4.65
Part 2: 69.75
Step-by-step explanation:
The first question is "How much money does she make from each bracelet after she pays herself back for the materials?"
To answer that, we must find how much she is selling them for ($9) and subtract the cost of the materials from it ($4.35), which equals 4.65
The second question is How much money does becca make from the sale of 15 bracelets?
In other words, they are only asking for the profit made which means they don't want the materials used cost included. So we can use the answer from before and multiply by 15, so 4.65*15=69.75.

Answers
The cosine function with a midline of 2, an amplitude of 3, and a period of 7π/4 is f(x) = 3 cos(8x/7) + 2.
A cosine function that has a midline of 2, an amplitude of 3, and a period of 7π/4 can be written in the form:
f(x) = A cos(Bx) + C, where:
A = amplitude
= 3C
= midline
= 2B
= 2π/period
= 2π / (7π/4)
