If f(x)=(1)/(3)x-5,g(x)=-4x^(2)-5x+9, and h(x)=(1)/(x-8)+3, find g(-2). Type your exact answer, simplified if necessary, in the empty text box.
To find g(-2), we'll substitute -2 for x in the equation g(x) = -4x² - 5x + 9. So,g(-2) = -4(-2)² - 5(-2) + 9g(-2). The value of g(-2) is -6.
To find g(-2), substitute -2 for x in the equation
g(x) = -4x² - 5x + 9 to get
g(-2) = -6 + 9g(-2)
We are given three functions as follows:
f(x) = (1/3)x - 5, g(x)
= -4x² - 5x + 9, and
h(x) = 1/(x - 8) + 3.
We are asked to find g(-2), which is the value of g(x) when x = -2.
Substituting -2 for x in the equation g(x) = -4x² - 5x + 9, we get
g(-2) = -4(-2)² - 5(-2) + 9.
This simplifies to g(-2) = -16 + 10 + 9 = -6.
Hence, g(-2) = -6.
The value of g(-2) is -6.

Given line segment AB with endpoints A(-1,7) and B(11, -1)
Find the length of AB.
Step-by-step explanation:
some to check if it correct
The length of the line segment AB is 8.48 unit.
What does length mean?The term used for identifying the size of an object or the distance from one point to another is known as length.
The length of the line segment having endpoints A (x1, y1) and B (x2, y2) can be determined using the formula,
\(AB=\sqrt{(x_{2} ^{2} -x_{1} ^{2} )+(y_{2} ^{2} - y_{1} ^{2} )}\)
Given that x1 = -1, x2= 11, y1= 7, and y2= -1.
Substituting the given values in the above equation
\(AB=\sqrt{(11^{2}-(-1)^2 )+((-1)^2-7^2)}\)
\(AB=\sqrt{72} = 8.48\)
Hence, 8.48 unit is the length of line segment AB.

Step-by-step explanation:
The events A and B are mutually exclusive. Suppose P(A)=0.24 and P(B)=0.27. a. What is the probability of either A or B occuring? b. What is the probability that neither A nor B will happen?
The probability of either event A or event B occurring is 0.51. The probability that neither event A nor event B will happen is 0.49.
a. Since events A and B are mutually exclusive, they cannot occur at the same time. The probability of either A or B occurring can be calculated by summing their individual probabilities:
P(A or B) = P(A) + P(B) = 0.24 + 0.27 = 0.51
Therefore, the probability of either event A or event B occurring is 0.51.
b. The probability that neither A nor B will happen can be found by subtracting the probability of A or B occurring from 1 (since the sum of all probabilities must equal 1):
P(neither A nor B) = 1 - P(A or B)
Since events A and B are mutually exclusive, the probability of A or B occurring is the same as the probability of either A or B occurring:
P(A or B) = 0.51
Therefore,
P(neither A nor B) = 1 - 0.51 = 0.49
So, the probability that neither event A nor event B will happen is 0.49.

(Round your answer to two decimal places 6.82 x min Suppose 4-year-olds in a certain country average 3 hours a day unsupervised and that most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is 1.8 hours and the amount of time spent alone is normally distributed. We randomly survey one 4-year-old living in a rural area. We are interested in the amount of time the child spends alone per day.
The probability that the child spends less than 1 hour per day unsupervised is approximately 0.1335.
To find the probability that the child spends less than 1 hour per day unsupervised, we can use the normal distribution and the given mean and standard deviation.
Given:
Mean (μ) = 3 hours
Standard Deviation (σ) = 1.8 hours
We want to find the probability that the child spends less than 1 hour per day unsupervised, which is equivalent to finding the area under the normal distribution curve to the left of 1 hour.
Using the Z-score formula:
Z = (x - μ) / σ
Substituting the values:
Z = (1 - 3) / 1.8
Z = -1.11
Now, we can use a Z-table or a calculator to find the probability associated with the Z-score of -1.11. The probability can be found as the area to the left of the Z-score.
Looking up the Z-score of -1.11 in the Z-table, we find the corresponding probability to be 0.1335.
So, the probability that the child spends less than 1 hour per day unsupervised is approximately 0.1335.
The probability statement is: p(x < 1) = 0.1335.

Mrs. Ades places tiles numbered 1 through 10 in a bag and assigns numbers 1-6 to Elias and tiles 7-10 to Maha. Each day, she draws a tile, and the person whose tile is drawn has to do chores. Is Mrs. Ades being fair? Explain.
Answer:
Mrs. Ades is not being fair. The probability of Elias and Maha getting chosen should be equal, but Elias has a 6/10 chance of being chosen, while Maha only has a 4/10 chance of being chosen. This is because Elias has 6 tiles assigned to him, while Maha only has 4 tiles assigned to her.
Explanation:
To make it fair, Mrs. Ades should assign each person an equal number of tiles, or draw from a bag with the tiles numbered 1 through 5 twice, assigning one to Elias and one to Maha each time, and then draw from a bag with tiles numbered 6 through 10 twice, assigning one to Elias and one to Maha each time.

A method for determining the volume of a solid of revolution of a solid-state material while integrating along an axis "parallel" to the axis of revolution is known as disc integration, also known as the disc method in integral calculus.
This technique stacks an endless number of discs with varied radii and minuscule thickness to produce the final three-dimensional form. To create hollow solids of revolutions, the same ideas may also be applied when using rings in place of discs (this is known as the "washer technique").
As opposed to this, shell integration integrates along an axis that is parallel to the axis of revolution. The solution can be seen in the attached images below.

well, from 1990 to 1998 is 8 years, and we know the amount went from $4800 to $6300, let's check for the rate of growth.
\(\qquad \textit{Amount for Exponential Growth} \\\\ A=P(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$6300\\ P=\textit{initial amount}\dotfill &\$4800\\ r=rate\to r\%\to \frac{r}{100}\\ t=\textit{years}\dotfill &8\\ \end{cases} \\\\\\ 6300=4800(1 + \frac{r}{100})^{8} \implies \cfrac{6300}{4800}=(1 + \frac{r}{100})^8\implies \cfrac{21}{16}=(1 + \frac{r}{100})^8\)
\(\sqrt[8]{\cfrac{21}{16}}=1 + \cfrac{r}{100}\implies \sqrt[8]{\cfrac{21}{16}}=\cfrac{100+r}{100} \\\\\\ 100\sqrt[8]{\cfrac{21}{16}}=100+r\implies 100\sqrt[8]{\cfrac{21}{16}}-100=r\implies \stackrel{\%}{3.46}\approx r\)

A line has a slope of 1/ 6 and passes through the point (–6,6). Write its equation in slope-intercept form.
Answer:
Step-by-step explanation:
The equation of the line with a slope of 1/6 passes through the point (-6, 5) is y=(1/6)x+6.
What is the equation of a line?
A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
Given that a line with a slope of 1/6 passes through the point (-6, 5). Therefore, we can write,
y = mx + c
Substitute the values,
5 = (1/6)(-6) + C
5 = -1 + C
5 + 1 = C
C = 6
Hence, the equation of the line with a slope of 1/6 passes through the point (-6, 5) is y=(1/6)x+6.
Answer:
y = (1/6)x + 7
Step-by-step explanation:
The slope-intercept form of the equation of a line is y = mx + b, where m is the slope and b is the y-intercept.
We know that the line has a slope of 1/6 and passes through the point (-6, 6). To find the y-intercept, we can substitute the values of the point into the equation and solve for b:
y = mx + b
6 = (1/6)(-6) + b
6 = -1 + b
b = 7
Now that we know the slope and y-intercept, we can write the equation of the line in slope-intercept form:
y = (1/6)x + 7
Therefore, the equation of the line in slope-intercept form is y = (1/6)x + 7.

Given a table of popcorn volumes and prices, you want to know a reasonable price for 60 ounces of popcorn.
TablePlotting the given sizes and costs on a graph, we see that the relationship is linear. Using the two points (size, cost) = (10, 6) and (20, 8), we find the relation to be ...
m = (y2 -y1)/(x2 -x1) = (8 -6)/(20 -10) = 2/10 = 0.2 . . . . slope
b = y1 -m(x1) = 6 -0.2(10) = 4 . . . . . . y-intercept
Then the equation of the line is ...
y = mx +b
y = 0.2x +4
ExtrapolationUsing x=60, we find the corresponding price is ...
y = 0.2(60) +4 = 12 +4 = 16
A consistent price is $16 for a 60-ounce container of popcorn.

Additional comment
The price equation suggests a fixed cost ($4) and a volume-related cost ($0.20 per ounce).
Two hikers start a trip from a camp walking 15 miles due east. They turn north and walk 17 miles to a large pond. How far is the pond from base camp to the nearest tenth of a miles.
Answer:
22.7 miles
Step-by-step explanation:
The hikers start walking 15 miles due east and then they turn north and walk 17 miles to a large pond.
The shape of their journey can be represented as a right angled triangle, shown below.
To find the distance between the pond and the base camp, we need to find the hypotenuse of the triangle.
We can do this by using Pythagoras theorem:
\(hyp^2 = a^2 + b^2\)
where a and b are the other two sides of the triangle. Therefore:
\(hyp^2 = 15^2 + 17^2\\\\hyp^2 = 514\\\\hyp = \sqrt{5`4} \\\\hyp = 22.7 miles\)
The pond is 22.7 miles far from the base camp.
