Find the area of the region bounded by the
curves:
y = 10 - x^2
y = x^2 + 8

Answers

Answer 1

The area of the region bounded by the curves is 4/3 square units.

To find the area of the region bounded by the curves y = 10 - [tex]x^2[/tex] and y = [tex]x^2[/tex] + 8, we need to find the points of intersection between the two curves.
Setting the two equations equal to each other, we have:
10 - [tex]x^2[/tex] = [tex]x^2[/tex] + 8
Simplifying, we get:
[tex]2x^2[/tex] = 2
[tex]x^2[/tex] = 1
x = ±1
Substituting x = 1 into either equation gives us:
y = 10 - [tex]1^2[/tex] = 9
And substituting x = -1 gives us:
y = 10 - [tex](-1)^2[/tex] = 10
So the two curves intersect at the points (1, 9) and (-1, 10).
To find the area of the region bounded by the curves, we need to integrate the difference between the two equations with respect to x, from x = -1 to x = 1:
∫[10 - [tex]x^2[/tex]] - [[tex]x^2[/tex] + 8] dx, from x = -1 to x = 1
= ∫(2 - 2[tex]x^2[/tex]) dx, from x = -1 to x = 1
= [2x - (2/3)[tex]x^3[/tex]] from x = -1 to x = 1
= 4/3
So

The area of the region bounded by the curves y = 10 - [tex]x^2[/tex] and y = [tex]x^2[/tex] + 8 is 4/3 square units.

Josh lit a 14-inch candle. She noticed that it was getting an inch shorter every 30 minutes. Let x be the number of hours and y be the total height of the candle

Answers

The height of the candle after x hours is given by the equation y = 2x + 14.

Let's first convert the time interval to hours. There are 60 minutes in an hour, so 30 minutes is equivalent to 0.5 hours.

After x hours, the candle will have burned down by 2x inches (since it burns 1 inch every 0.5 hours).

If y is the total height of the candle, then we can write the equation:

y - 2x = 14

We can solve for y:

y = 2x + 14

Answers

The net worth of the Worthington family is $28,900, which is greater than the requirement of $100,000 for the loan. Therefore, they meet the net worth requirement for the loan.

To calculate the net worth of the Worthington family, we need to add up all their assets and subtract their liabilities (debts). Let's start by listing them:

Assets:

- Savings account: $18,800

- Vehicles: $64,600

- Antique necklace: $6,200

- College fund: $24,700

Total assets: $114,300

Liabilities:

- Mr. Worthington's student loans: $85,400

Total liabilities: $85,400

To calculate the net worth, we subtract the liabilities from the assets:

Net worth = Total assets - Total liabilities

Net worth = $114,300 - $85,400

Net worth = $28,900

The net worth of the Worthington family is $28,900, which is greater than the requirement of $100,000 for the loan. Therefore, they meet the net worth requirement for the loan.

What is interest?

The measure of cash returned or earned over a set period of time on a principal sum of money is referred to as interest. It is frequently stated as a share of the principal sum and it may be either simple or complicated. Compounding interest is computed on the principal amount as well as any accrued but unpaid interest, whereas simple interest is assessed just on the principal amount. Loans, investments, and bank deposits frequently include interest.

=c , where k and c are constants, what is the value of k?

Answers

Answer:

Given the equation of the circle in the xy-coordinate plane as x^2 + y^2 + 6x - 4 = 0, we need to rewrite it in the form (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center of the circle and r is the radius.

Completing the square for x^2 + 6x, we get (x+3)^2 - 9. Thus, the equation becomes (x+3)^2 + y^2 - 9 = 4. Rearranging, we get (x+3)^2 + y^2 = 13.

Comparing with the required form, we get (x-h)^2 + (y-k)^2 = r^2, where h = -3, k = 0 and r^2 = 13. Thus, the value of k is 0.

Answers

Jonah's mom's would have to spend $45.878 to fill up her tank after the 40% increase in gas prices if her car takes 14 1/2 gallons of gas to fill up.

To find the cost that Jonah's mom would have to spend after the 40% increase in gas prices to fill up her 14 1/2 gallon tank, we need to follow these steps:

1. Find the increased price per gallon by multiplying last summer's price ($2.26) by 1.40 (since there's a 40% increase): $2.26 x 1.40 = $3.164 per gallon.
2. Convert 14 1/2 gallons to a decimal: 14.5 gallons.
3. Multiply the increased price per gallon ($3.164) by the number of gallons needed to fill up the tank (14.5 gallons): $3.164 x 14.5 = $45.878.

Answers

36 bags of soil are required to spread a 6 feet layer over a garden bed that is 4 feet by 3 feet.

How many bags of soil are required to spread a 4 feet layer over the garden bed?

Given information:

The garden bed has a length of 4 feet.

The garden bed has a width of 3 feet.

The layer of soil to be spread over the garden bed is 6 feet.

One bag of soil contains 2 cubic feet of soil.

To find the number of bags of soil required to spread a 6 feet layer over the garden bed, we need to calculate the volume of soil needed and then divide it by the volume of each bag of soil.

The volume of soil needed can be calculated by multiplying the length, width, and height (depth) of the soil:

Volume = length x width x depth

Volume = 4 feet x 3 feet x 6 feet

Volume = 72 cubic feet

This means we need a total of 72 cubic feet of soil to spread a 6 feet layer over the garden bed.

Next, we need to determine the number of bags of soil required. Since each bag contains 2 cubic feet of soil, we can divide the total volume of soil needed by the volume of each bag to get the number of bags required:

Number of bags = Volume of soil needed / Volume of each bag

Number of bags = 72 cubic feet / 2 cubic feet per bag

Number of bags = 36 bags

Therefore, 36 bags of soil are required to spread a 6 feet layer over a garden bed that is 4 feet by 3 feet.

What is the unit rate of change of ddd with respect to ttt? (That is, a change of 111 unit in ttt will correspond to a change of how many units in ddd?)

The unit rate is

.

Graph the relationship.
















Answers

The unit rate of change of ddd with respect to ttt is 4/3.

To graph the proportional relationship between ddd and ttt, we first need to find the unit rate of change. Since an increase of 333 units in ttt corresponds to an increase of 444 units in ddd, we can calculate the unit rate as follows:

Unit Rate = (Change in ddd) / (Change in ttt) = 444 / 333 = 4/3

So, a change of 1 unit in ttt corresponds to a change of 4/3 units in ddd.

Now, let's graph the relationship. The equation representing this proportional relationship is:

ddd = (4/3)ttt

This is a linear relationship with a slope of 4/3 and passes through the origin (0,0). To plot the graph, start at the origin and use the slope to plot additional points, such as:
- For ttt = 3, ddd = 4 (since 4/3 * 3 = 4)
- For ttt = 6, ddd = 8 (since 4/3 * 6 = 8)

Plot these points and draw a straight line through them, representing the proportional relationship between ddd and ttt. The unit rate of change of ddd with respect to ttt is 4/3.

A quantitative data set has mean 25 and standard deviation 2. At least what percentage of the observations lie between 19 and 31 ​?

Answers

At least 95% of the observations lie between 19 and 31.

To see why, we can use Chebyshev's theorem, which states that for any data set, regardless of the shape of the distribution, at least 1 - (1/k²) of the observations lie within k standard deviations of the mean. In this case,

we want to know the percentage of observations that lie within two standard deviations of the mean, since 19 and 31 are both two standard deviations away from the mean of 25.

So, we can use k = 2 in Chebyshev's theorem, which gives us:

1 - (1/2²) = 1 - (1/4) = 0.75

Therefore, at least 75% of the observations lie within two standard deviations of the mean. However, since we know the data set is normally distributed (since we know the mean and standard deviation), we can use the empirical rule,

which states that for normally distributed data, approximately 68% of the observations lie within one standard deviation of the mean, and approximately 95% of the observations lie within two standard deviations of the mean.

Therefore, we can conclude that at least 95% of the observations lie between 19 and 31.

This tells him that his salary is significantly below the average salary of quality management professionals surveyed by the ASQ, and that he is in the bottom percentile of salaries in this group.

The z-score is a statistical measure that indicates the number of standard deviations that a data point is from the mean of a distribution. A negative z-score indicates that the data point is below the mean.

In this case, the quality control specialist's z-score of -2.50 indicates that his salary is 2.50 standard deviations below the mean salary of the quality management professionals surveyed by the ASQ.

Without knowing the specific mean and standard deviation provided by the survey, it is difficult to determine the exact value of the specialist's salary. However, we can use the z-score to estimate the percentile rank of his salary compared to the rest of the survey respondents.

Using a standard normal distribution table, we can see that a z-score of -2.50 corresponds to a percentile rank of approximately 0.0062 or 0.62%.

Marcia drew a plan for a rectangular piece of material that she will use for a blanket. Three of the vertices are (-1.3, -3.5), (-1.3, 1.4), and (3.9,1.4) . What are the coordinates of the fourth​ vertex?

Answers

The coordinates of the fourth vertex is (3.9, 6.3,0).To find the coordinates of the fourth vertex, we can use the fact that opposite sides of a rectangle are parallel and equal in length.

We can find the length and slope of one side of the rectangle and then use that information to find the coordinates of the fourth vertex.

Let's start by finding the length and slope of the side connecting (-1.3, -3.5) and (-1.3, 1.4). The length of this side is the difference between the y-coordinates, which is:

1.4 - (-3.5) = 4.9

Since this side is vertical, its slope is undefined.

Next, let's find the length and slope of the side connecting (-1.3, 1.4) and (3.9, 1.4). The length of this side is the difference between the x-coordinates, which is:

3.9 - (-1.3) = 5.2

Since this side is horizontal, its slope is 0.

Since opposite sides of a rectangle are equal in length, the length of the side connecting (-1.3, 1.4) and (3.9, 1.4) must also be 4.9. We can use this length to find the y-coordinate of the fourth vertex, which is:

1.4 + 4.9 = 6.3

Now we know that the fourth vertex has coordinates (x, 6.3). To find the x-coordinate, we can use the length of the vertical side connecting (-1.3, -3.5) and (-1.3, 1.4), which is also 5.2. The x-coordinate of the fourth vertex is:

-1.3 + 5.2 = 3.9

Part A: The given definition states that an angle is two collinear rays with a common endpoint. Part B : A point is an example of an undefined term.In relation to angles, a point is crucial as it serves as the common endpoint of the two rays that form the angle.

Part A :  The given definition states that an angle is two collinear rays with a common endpoint. However, this definition is incorrect as it contradicts the correct definition of an angle. In the correct definition, an angle is formed by two non-collinear rays with a common endpoint.


An example that contradicts the given definition is when you have two rays, AB and BC, with B being the common endpoint. If they were collinear, they would lie along the same straight line, and thus, no angle would be formed between them. To make the definition accurate, you would need to change it to: "An angle is formed by two non-collinear rays with a common endpoint."


Part B: An undefined term in geometry is a term that cannot be defined using other known geometric terms, but its meaning is generally understood. One example of an undefined term is a point. A point is a basic element in geometry, and it has no size, shape, or dimensions. It is merely a location in space. For instance, when discussing angle ABC, point B is the common endpoint of rays AB and BC.

what percent of stainless steel in the tank is used to make the two ends

Answers

Answer:

The percentage of stainless steel used to make the two ends of the tank cannot be determined without additional information. Please provide more details about the tank and its construction.

Step-by-step explanation:

To calculate the percentage of stainless steel used to make the two ends of the tank, we need to know the total amount of stainless steel used to make the entire tank, as well as the amount used to make the ends. Without this information, it is impossible to determine the percentage of stainless steel used for the ends.

For example, if the tank is made entirely of stainless steel, then the percentage of stainless steel used to make the ends would be 100%. However, if the tank is made of multiple materials, then the percentage of stainless steel used for the ends would depend on the amount of stainless steel used for the entire tank and the amount used for the ends.

Therefore, to calculate the percentage of stainless steel used for the ends of the tank, we need additional information about the tank's construction and materials.

Is there evidence that the true mean number of hours of screen time for US adults is greater than 3. 5?

Answers

For the given case, there is evidence that the true mean number of hours of screen time for US adults is greater than 3.5.


Here, the researcher is 95% confidence interval from 3.6 hours to 8.1 hours captures  y = the true mean amount of daily screen time for US adults.
If 3.5 hours falls below this interval, it is likely that the true mean number of hours of screen time for US adults is greater than 3.5 hours.


A confidence interval is a measure of values that is used to evaluate a statistical parameter which tends to involve the true form of the parameter a predetermined proportion of the time if the procedure of searching the group of values is repeated numerous times.

Circle Q has a diameter AB. If the distinct point C is also on the circle then triangle ABC must be

Answers

If point C is on the circle with diameter AB, then triangle ABC must be a right triangle. This is because the diameter of a circle is the longest chord and it passes through the center of the circle.

If we draw a line from point C to the center of the circle (which is the midpoint of AB), we get a perpendicular bisector of AB, meaning that it cuts AB into two equal parts and forms right angles with it. This also means that AC and BC are equal in length (since they both form radii of the circle), and the angle at point C must be a right angle (since it forms a straight line with the center of the circle). Thus, triangle ABC satisfies the criteria for a right triangle.

In summary, if point C lies on the circle with diameter AB, then triangle ABC must be a right triangle with AC and BC as its legs and AB as its hypotenuse. This is a fundamental property of circles and right triangles, and it is important to understand in order to solve various geometry problems involving circles and triangles.

Write a derivative formula for the function.
f(x) = 2x√7x+8 + 96

Answers

The derivative formula of the given function f(x) is:

f'(x) = 2√(7x+8) + 7x/(√(7x+8))

This formula gives the value of the derivative of the function f(x) for any value of x.

How we find derivative?

The derivative of f(x) using the product rule and chain rule:

f'(x) = 2√(7x+8) + 2x(1/2)(7x+8)^(-1/2)(7)

f'(x) = 2√(7x+8) + 7x/(√(7x+8))

Simplify the derivative

The derivative of the function f(x) is given by f'(x) = 2√(7x+8) + 7x/(√(7x+8))

In this formula, the first term represents the derivative of the function 2x√(7x+8) using the chain rule, and the second term represents the derivative of the function 96, which is a constant and has a derivative of zero.
