The water rate for a city in North Carolina is $1.39 per 755 gallons of water used. a) What is the water bill if a resident of that city uses 30,000 gallons? b) How many gallons of water can a customer use if the water bill is not to exceed $150?
The gallons of water a customer can use if the water bill is not to exceed $150 is 81474.82 gallons
What is the water bill if a resident of that city uses 30,000 gallons?
In order to determine the water bill, we need to calculate the price of one gallon of water (rate) using the given information.
Since $1.39 per 755 gallons
rate = 1.39/ 755
The water bill if a resident of that city uses 30,000 gallons will be:
1.39/ 755 * 30000 = $55.23
The gallons of water a customer can use if the water bill is not to exceed $150 will be:
Let x be gallons of water
(1.39/ 755)x ≤ 150
x ≤ 150/(1.39/ 755)
x ≤ 81474.82 gallons

The required global maximum value is 4 and the global minimum value is 3.
What is implicit differentiation?The method of determining the derivative of an implicit function by differentiating each term separately, expressing the derivative of the dependent variable as a symbol, and solving the resulting expression for the symbol.
Here,
The critical points can be found by finding the partial derivatives of the function with respect to x and y and setting them equal to zero.
df/dx = 2x - 2y = 0
df/dy = -2x + 4y = 0
Solving the system of equations, we find that the critical points are (1, 2) and (2, 1).
Since (1, 2) is within the bounds of the rectangle D, we need to check the value of f(1, 2) to see if it is a local minimum or local maximum.
f(1, 2) = 1 - 2 + 4 = 3
(2, 1) is also within the bounds of the rectangle D, we need to check the value of f(2, 1) to see if it is a local minimum or local maximum.
f(2, 1) = 4 - 2 + 2 = 4
Since f(1, 2) < f(2, 1), the global maximum is at point (2, 1) and the global minimum is at point (1, 2).
The global maximum value is 4 and the global minimum value is 3.

Read the following problem carefully! The amount of work, W, required to move a particle of mass M a vertical distance d above its starting height is given by the formula,W=Mgdwhere g is the acceleration due to gravity. A heavy rope is 15 m long and has a constant (linear) density of rho=2 kg/m. The rope hangs over the edge of a 25 m building, as shown below: The work required to pull the rope to the top of the building cannot be computed using the above formula because the distance each part of the rope must be moved is different! Answer the following questions and put your final answer for each part in the box. I. (The Approximate Work) A. On the figure above, the rope has been divided into three segments of equal length,Δy.

B. The mass of the middle segment is the length of the segment 10 kg.
C. The y values of the bottom of each segment are y₀ = 0, y₁ = 5 m, and y₂ = 10 m.

What do you mean by acceleration?Acceleration is a measure of the change in velocity over time. In physics, acceleration is defined as the rate of change of velocity, or the second derivative of position with respect to time. Acceleration is a vector quantity that has both magnitude and direction, and its unit is meters per second squared (m/s²).
A positive acceleration indicates an increase in speed, while a negative acceleration indicates a decrease in speed or a change in direction. In everyday life, we encounter examples of acceleration in movements such as starting a car, stopping a car, or changing direction while driving.
A. The length of each segment of the rope is 15 m / 3 = 5 m.
B. The mass of the middle segment is the length of the segment multiplied by the density of the rope: M2 = 5 m × 2 kg/m = 10 kg.
C. The y values of the bottom of each segment are y0 = 0, y1 = 5 m, and y2 = 10 m.
D. The distance d2 the middle segment must be moved is 25 m - 10 m = 15 m.
Therefore, the work required to move the middle segment can be approximated using the formula W = M2 × g × d2, where g is the acceleration due to gravity. The exact value of the work required to move the entire rope would need to take into account the different distances that each segment must be moved.

(a) Specify the sample space of each experiment. (b) Find the relative frequency of each outcome in each of the above experiments in a large number of repetitions of the experiment. Explain your answer.
To fully get the answer on the sample space and relative frequency, let's go directly to the analysis of the experiments as given.
The random experiments and their outcome(a) Sample space:
Experiment 1: Toss a coin: The sample space of this experiment is {heads, tails}.Experiment 2: Toss a die: The sample space of this experiment is {1, 2, 3, 4, 5, 6}.Experiment 3: Select a ball at random from an urn containing balls numbered 0 to 9: The sample space of this experiment is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}.(b) Relative frequency of each outcome:
Relative frequency of an outcome is the number of times the outcome appears divided by the total number of trials. In a large number of repetitions of an experiment, the relative frequency of each outcome approaches the theoretical probability of that outcome.
Experiment 1: Toss a coin: Since each outcome (heads or tails) is equally likely, the theoretical probability of each outcome is 0.5. In a large number of repetitions of the experiment, the relative frequency of heads and tails would approach 0.5.Experiment 2: Toss a die: Since each outcome (1 to 6) is equally likely, the theoretical probability of each outcome is 1/6. In a large number of repetitions of the experiment, the relative frequency of each outcome (1 to 6) would approach 1/6.Experiment 3: Select a ball at random from an urn containing balls numbered 0 to 9: Since each outcome (0 to 9) is equally likely, the theoretical probability of each outcome is 1/10.

What is P(A)P, left parenthesis, A, right parenthesis, the probability that a customer has enough cash?
the value of P(A∪B) is 17/20.
What is probability?Probability is a number expressing the likelihood or chance that a specific event will occur. Proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, A neighborhood restaurant is serving dinner to 20 patrons.
Both cash and credit are accepted as modes of payment at the restaurant. Of the 20 customers, 3 have enough cash and a credit card to pay for their dinner, 16 have a credit card, and 4 have enough cash to cover the cost of their meal.
From the general formula of probability:
Probability = (desired outcomes)/(Total outcomes)
Let "A" represent the situation in which a randomly chosen consumer has enough cash,
"B" represents the situation in which a randomly chosen customer has a credit card.
thus,
P(A) = 4/20
P(A) = 1/5
P(B) = 16/20
Also given,
P(A∩B) = 3/20
Since,
P(A∪B) = P(A) + P(B) -P(A∩B)
P(A∪B) = 4/20 + 16/20 - 3/20
P(A∪B) = 17/20

The Bitcoin economy had reported year-on-year growth from 2017 to 2019 at a yearly rate of 7%. In 2020 it went into a downward trend. That year the growth turned negative at -5%. If the negative growth doubled the next year, what was the approximate percentage increase or decrease of the bitcoin economy in that year, compared to 2018?
SELECT ONLY ONE
Approximately 9% decrease
Approximately 13% decrease
Approximately 3% increase
Approximately 5% increase
If the Bitcoin economy had a yearly growth rate of 7% from 2017 to 2019, then the value in 2019 would be $1.07^3 = $1.225. If the economy had a negative growth rate of 5% in 2020, then the value in 2020 would be $1.225 x 0.95 = $1.1638. If the negative growth rate doubled in the next year, then the value in the next year would be $1.1638 x 0.9 = $1.04742.
To calculate the percentage change from 2018 to the next year, we can compare the values of the Bitcoin economy in those two years. The value in 2018 would be $1.07^2 = $1.1449. The percentage change would be ((value in next year - value in 2018) / value in 2018) x 100%. Substituting the values, we get ((1.04742 - 1.1449) / 1.1449) x 100% = -8.5%.
Therefore, the approximate percentage decrease of the Bitcoin economy in the next year, compared to 2018, is approximately 9%. The closest option is "Approximately 9% decrease".
The height of a rectangular box is 4 times its length, and its width is 7 in more than its length. The volume of the box is 102 in^3. Use the ALEKS graphing calculator to find the length of the box. Round your answer to two decimal places.
Answer: Let's call the length of the box "x". Then, the height of the box is 4x and the width is x + 7. The volume of the box is given by the equation:
x * 4x * (x + 7) = 102
Expanding and simplifying the equation, we get:
4x^3 + 28x^2 - 102 = 0
To find the length of the box, we need to solve for x in this equation. One way to do this is to use the cubic formula. However, this formula can be quite complex, so a simpler method would be to use numerical methods such as the bisection method or Newton's method.

(2) Melissa and Ron entered a competition as a team Ron's score was 4/9 of Melissa's score. Melissa scored 50 more points than Ron. How many points did Melissa score?
The number of points that Melissa scored would be = 89 points.
How to calculate the number of point scores by Melissa?The competition was carried out by these two individuals that had different scores such as follows:
The total number of scores for Melissa = 50 point + Ron's score. That is , y = 50+X. ---> eq 1
The total number of Ron's score X = 4/9 × y --> 2
substitute y into equation 2.
X = 4/9× (50+X)
X= 22 + 0.44x
0.56x= 22
X= 22/0.56
X= 39.
substitute X into equation 1;
y= 50+39
y = 89

About elimination methodThe elimination method is a method used to solve or find a set of solutions to a system of linear equations of two variables by eliminating one of the variables. If the variables are x and y, to determine the x variable we must first eliminate the y variable, or vice versa, if we want to find the y variable, we must first eliminate the x variable.
To eliminate a variable, it must have the same coefficient. So if the coefficients of the variables are not the same then first equate the coefficients by multiplying or dividing them. Then only can determine other variables that will be determined. So in the elimination method you need to eliminate the variable twice.

Let f(w) x 10x . We want to estimatef(1.07) using linear approximations. That is, using an appropriate tangent line_ First, we will build the tangent line at (€, y_ Enter as an ordered pair (a,6) The slope of the tangent line comes from f For this problem, f' (c) = And mtan The equation of the tangent line, in slope intercept form, is y = T(c) = Now, f(1.07) ~ T(1.07) Compare to actual value f(1.07)
The linear approximation of f(1.07) using the tangent line is T(1.07) is 10.77, which is slightly lower than the actual value f(1.07) = 11.77.
First, we need to find the derivative of the function f(x) = x + 10x.
The derivative is given by:
f'(x) = 1 + 10
Next, we need to find the tangent line at the point (a, 6), which means we need to find the value of "a" that makes the tangent line pass through (a, 6). To do this, we use the equation of the tangent line:
y - 6 = (1 + 10)(x - a)
y = (1 + 10)(x - a) + 6
Now we need to use the value of "a" to find the value of f(a) and then use this to find the value of the linear approximation of f(1.07).
Let's assume that the value of "a" is 1.
So, f(a) = f(1) = 1 + 10(1) = 11
And the equation of the tangent line is:
y = (1 + 10)(x - 1) + 6 = 11x - 4
Now, to find the value of the linear approximation of f(1.07), we use the equation of the tangent line:
T(1.07) = 11 * 1.07 - 4 = 10.77
Finally, we compare this value with the actual value of f(1.07), which is:
f(1.07) = 1.07 + 10 * 1.07 = 11.77

Let X be a continuous random variable taking values between 0 and 2 with probability density function p(x) = 0.5. Find E(X) and Var(X). Plot its Cumulative Distribution Function.
E(X) = 2 and Var(X) = 4/3.
And then, Here's a plot of the CDF of X:
[Plot of the CDF of X with x on the x-axis and F(x) on the y-axis, showing a line with slope 0.5 for x in [0,2]]
Continuous Random Variable ExpectationsThe expected value (mean) of a continuous random variable X with probability density function p(x) is given by:E(X) = ∫x*p(x)dx, where the integral is taken over the range of X.
In this case, since p(x) = 0.5 for all x in [0,2], we have:E(X) = ∫x*0.5dx = 0.5∫xdx = 0.5(x²/2)|0 to 2 = (2²/2 - 0²/2)*0.5 = 2.
The variance of X is given by:Var(X) = E((X - E(X))²) = E(X²) - (E(X))².
We have to calculate E(X²), which can be found as:E(X²) = ∫x²*p(x)dx = 0.5∫x²dx = 0.5(x²/3)|0 to 2 = (2²/3 - 0³/3)*0.5 = 8/3.
So, Var(X) = E(X²) - (E(X))² = 8/3 - (2)² = 8/3 - 4 = 4/3.
The cumulative distribution function (CDF) of a continuous random variable X is given by:F(x) = P(X <= x) = ∫p(t)dt for all t <= x.
In this case, since p(x) = 0.5 for all x in [0,2], we have:F(x) = 0.5x for x in [0,2].
The CDF of X is a monotonically increasing function, and it tells us the probability that X takes a value less than or equal to x.
Now, Here's a plot of the CDF of X:
[Plot of the CDF of X with x on the x-axis and F(x) on the y-axis, showing a line with slope 0.5 for x in [0,2]]

Solve the triangle:
Answer:
Step-by-step explanation:
we will find the first angle in the larger triangle;
180⁰-60⁰= 120⁰
120⁰
the second angle will be;
120⁰+30⁰=150⁰
180⁰-150⁰=30⁰
30⁰ this means that the second triangle is isosceles triangle, when we find the hypotenuse of the smaller triangle it will be equal to x since the sides are equal
88/sin60⁰=x/sin90⁰
88sin 90⁰=xsin60⁰
88/0.8660=0.8660x/0.8660
x=101.62
