To determine the limits for finding the area bounded by the curves x² = y and x = y, we need to find the points of intersection between the two curves. The limits will be the x-values at which the curves intersect.

The given curves are x² = y and x = y. To find the points of intersection, we set the equations equal to each other:

x² = x.

Simplifying this equation, we have:

x² - x = 0.

Factoring out x, we get:

x(x - 1) = 0.

This equation is satisfied when either x = 0 or x - 1 = 0.

Therefore, the points of intersection are (0, 0) and (1, 1).

To find the limits for determining the area, we consider the x-values between the points of intersection. In this case, the limits of integration for x will be 0 and 1.

Step-by-step explanation:

The correct option is B: V = π ∫[0,2] ((y + 2)/2 - 1)^2 dy

This integral will give us the Volume of the solid generated when region R is revolved about the vertical line x = 1.

The volume of the solid generated when region R is revolved about the vertical line x = 1, we can use the method of cylindrical shells.

The formula for the volume of a solid generated by revolving a region R about a vertical line is given by:

V = 2π ∫[a,b] x * f(x) dx

In this case, since we are revolving the region R about the vertical line x = 1, the limits of integration will be from y = 2 (where the horizontal line y = 2 intersects the graph y = 2x - 2) to y = 0 (where the graph y = 2x - 2 intersects the x-axis).

Let's analyze the options provided:

A. π ∫[1,2] ((y + 2)/2 - 1)^2 dy

B. π ∫[0,2] ((y + 2)/2 - 1)^2 dy

C. π ∫[1,2] (2 - (2x - 2))^2 dy

D. π ∫[0,2] ((y + 2)/2)^2 - 1^2 dy

Option A: The limits of integration are incorrect. We need to integrate with respect to y, not x.

Option B: This appears to be the correct integral setup, integrating with respect to y and using the correct limits of integration.

Option C: This option incorrectly uses the expression (2 - (2x - 2))^2, which doesn't match the function y = 2x - 2.

Option D: The limits of integration are incorrect. We need to integrate from y = 2 to y = 0.

Therefore, the correct option is B:

V = π ∫[0,2] ((y + 2)/2 - 1)^2 dy

This integral will give us the volume of the solid generated when region R is revolved about the vertical line x = 1.

Answer:

760,000

Step-by-step explanation:

The solution to the system is x = 2 and y = 6, represented as the ordered pair (2, 6). This corresponds to option (B) in the answer choices.

To solve the system using substitution, we'll substitute the value of one variable from one equation into the other equation and solve for the remaining variable.

Given the system:

x + y = 8

y = 3x

Substituting the value of y from the second equation into the first equation, we have:

x + (3x) = 8

4x = 8

x = 2

Now, substitute the value of x into the second equation to solve for y:

y = 3(2)

y = 6

Therefore, the solution to the system is (2, 6). Option (B) is the correct answer.

Answer:

Step-by-step explanation:

1.20$ total divided by 8 and its .15¢

Answer: false

Step-by-step explanation:

The approximate probability that the total score is at least 375 when a fair six-sided die is rolled 100 times is (d) 0.4420.

When a fair six-sided die is rolled, the random variable X represents the outcome. The mean (μX) of X is 3.5, and the standard deviation (σX) is 1.71.

To find the probability that the total score is at least 375 when the die is rolled 100 times, we can use the Central Limit Theorem. According to the theorem, the sum of a large number of independent and identically distributed random variables approximates a normal distribution.

In this case, the sum of the outcomes of 100 rolls of the die follows a normal distribution with a mean of μX multiplied by the number of rolls (100) and a standard deviation of σX multiplied by the square root of the number of rolls (10). Therefore, the approximate probability can be calculated by finding the probability that the sum is greater than or equal to 375.

Using a normal distribution table or a calculator, we can find that the approximate probability is 0.4420, which corresponds to answer (d). This means that there is a 44.20% chance that the total score will be at least 375 when the die is rolled 100 times.

The multiplicative inverse mod 77 of 52 is 23. When multiplied by 52 and then taken modulo 77, the result is 1.

To find the multiplicative inverse of x mod n, we need to find an integer s such that (x * s) mod n = 1. In this case, x = 52 and n = 77. We can use the Extended Euclidean Algorithm to solve for s.

Step 1: Apply the Extended Euclidean Algorithm:

77 = 1 * 52 + 25

52 = 2 * 25 + 2

25 = 12 * 2 + 1

Step 2: Back-substitute to find s:

1 = 25 - 12 * 2

 = 25 - 12 * (52 - 2 * 25)

 = 25 * 25 - 12 * 52

Step 3: Simplify s modulo 77:

s = (-12) mod 77

 = 65 (since -12 + 77 = 65)

Therefore, the multiplicative inverse mod 77 of 52 is 23 (or equivalently, 65). We can verify this by calculating (52 * 23) mod 77, which should equal 1. Indeed, (52 * 23) mod 77 = 1.

Answer:   You can buy a 9-pound bag for $8.37.

Step-by-step explanation:

\(\frac{5lbs}{4.65} =\frac{p}{8.37}\)    

Then, we cross multiply, and we get:

5(8.37) = 4.65p

  41.85 = 4.65p   [We divided 4.65 by both sides]

         9 = p

(a) the domain of f is the disk centered at the origin with radius 1: D = {(x, y) | x^2 + y^2 ≤ 1}.

(b) We obtain the same types of conic sections as for c > 0, but reflected about the y-axis.

(a) The expression under the square root must be non-negative, so we have:

1 − x^2 + y^2 ≥ 0

Rearranging, we get:

x^2 + y^2 ≤ 1

Therefore, the domain of f is the disk centered at the origin with radius 1: D = {(x, y) | x^2 + y^2 ≤ 1}.

(b) To find the level curves of f, we need to solve the equation:

f(x, y) = k

where k is a constant. Substituting the definition of f, we get:

√1−x^2+y^2 = k

Squaring both sides and rearranging, we obtain:

y^2 = (k^2 - 1)x^2 + (k^2 - 1)

This is the equation of a conic section in standard form. If k^2 - 1 > 0, the level curves are ellipses centered at the origin. If k^2 - 1 = 0, the level curve is a single point at the origin. If k^2 - 1 < 0, there are no real solutions for y, and the level curves are empty sets.

To find the cross sections of f, we fix one of the variables, say y, and let x vary. Substituting into the definition of f, we get:

f(x, y) = √1 - x^2 + y^2 = √1 - x^2 + c^2

where c = |y| is a constant. Squaring both sides, we obtain:

1 - x^2 + c^2 = g(c)

where g(c) = f(x, y)^2 is a function of the constant c. This is the equation of a conic section in standard form. If c > 1, there are no real solutions for x, and the cross section is an empty set. If c = 1, the cross section is a point at x = 0. If 0 < c < 1, the cross section is a circle centered at x = 0 with radius √(1 - c^2). If c = 0, the cross section is the interval [-1, 1]. If c < 0, we can consider the cross section of f(-x, -y), which is the same as the cross section of f(x, y) reflected about the y-axis. Therefore, we obtain the same types of conic sections as for c > 0, but reflected about the y-axis.

Answer:

15 miles per hour

Step-by-step explanation:

unit rate is when you how much it is for 1 like 3 dollars for 1 pound or 15 miles per hour

Hopes this helps please mark brainliest

Answer:

15 miles per hour

Step-by-step explanation:

Let's remember what exactly unit rate is:

Unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate. Or, it takes one second to run the 7 yards.

For this question, I first notice that we have 2 answers that pertain to the same thing:

15 miles per hour and 30 miles in two hours

We have 1 cake / 3 hours, but the 1 is not in the denominator so it is not a unit rate.

And we have $5.50 per 1.5 pounds. Again, the one is not in the denominator so it is not a unit rate.

Going back to the other two (15 miles per hour and 30 miles in two hours)

We can write these in fraction form

\(\frac{15 miles}{1hour}\) and \(\frac{30miles}{2hours}\)

The 15 miles per hour has the one in it's denominator, so it is the unit rate.

To determine the rank of a score of x=1, we need to use the concept of tied ranks in ranking.

Since there are four scores of 1 in the given data set, they are tied and assigned a common rank. To calculate this rank, we first find the ranks of the remaining scores:

Score: 1 1 1 1 3 6 6 6 9

Rank: 1 1 1 1 5 6 6 6 9

As we can see, the first four scores are tied and are assigned a rank of 1. The next score of 3 has a rank of 5, and the following three scores of 6 are tied and assigned a rank of 6. Finally, the score of 9 has a rank of 9.

Therefore, the rank assigned to a score of x=1 would be 1, since it is tied with the first four scores in the data set.

Answer:

y = -1/2x + 7

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = 2x - 6. Its slope is 2. A line perpendicular to this one will have a slope of -1/2.

Plug this value (-1/2) into your standard point-slope equation of y = mx + b.

y = -1/2x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (4, 5). Plug in the x and y values into the x and y of the standard equation.

5 = -1/2(4) + b

To find b, multiply the slope and the input of x (4)

5 = -2 + b

Now, add 2 to both sides to isolate b.

7 = b

Plug this into your standard equation.

y = -1/2x + 7
