The expression for the power delivered to a resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

According to the given information, the power delivered to a resistance R when an alternating current of frequency f and peak current I_0 passes through it is represented by the equation P = I^2_0 R sin^2 2 pi ft.

To express this equation in terms of csc^2 2 pi ft, we can use the trigonometric identity csc^2 x = 1/sin^2 x. Substituting this identity into the equation, we get P = I^2_0 R (1/sin^2 2 pi ft).

Since csc^2 x is the reciprocal of sin^2 x, we can rewrite the equation as P = I^2_0 R (csc^2 2 pi ft). This expression represents the power delivered to the resistance in terms of csc^2 2 pi ft.

Therefore, the correct expression for the power delivered to the resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

Answer: a + 3b = 8

Step-by-step explanation:

a + b = 4 is true, since (2,2) works:  2 + 2 = 4

Try (2,2) in the options to find which one is true for (2,2):

A)  2 + 3*2 = 4?  No.

B)  4 + 4 = 2?  No.

C)  8 + 8 = 8?  No.

D)  2 + 6 = 8?  YES.

Therefore, a + 3b = 8 can be another valid equation.

Answer:

D. a + 3b = 8

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

These are three examples of 2x2 matrices (other than A = I and A = -I) that satisfy A² = I.

To find matrices that are their own inverses, we need to find matrices A such that A² = I, where I is the identity matrix.

Here are three examples of 2x2 matrices that satisfy A² = I:

A = [[1, 0], [0, -1]]

A² = [[1, 0], [0, -1]] * [[1, 0], [0, -1]] = [[11 + 00, 10 + 0(-1)], [01 + (-1)0, 00 + (-1)(-1)]]

= [[1, 0], [0, 1]]

Therefore, A is its own inverse.

A = [[0, 1], [1, 0]]

A² = [[0, 1], [1, 0]] * [[0, 1], [1, 0]] = [[00 + 11, 01 + 10], [10 + 01, 11 + 00]]

= [[1, 0], [0, 1]]

Therefore, A is its own inverse.

A = [[1, 1], [-1, 1]]

A² = [[1, 1], [-1, 1]] * [[1, 1], [-1, 1]] = [[11 + 1(-1), 11 + 11], [-11 + 1(-1), -11 + 11]]

= [[0, 2], [-2, 0]]

Therefore, A is its own inverse.

These are three examples of 2x2 matrices (other than A = I and A = -I) that satisfy A² = I.

The ordered pair lie on the inverse of the function is (62,−3).

Option A is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = -(x - 1)³ - 2

The inverse of f(x).

y = -(x - 1)³ - 2

interchange x and y and solve for y.

x = -(y - 1)3 - 2

(y - 1)³ = -2 - x

(y - 1)³ = -(2 + x)

Cuberoot on both sides.

y - 1 = ∛-(2 + x)

y = ∛-(2 + x) + 1

Now,

Substitute in the inverse of g(x).

(62, -3) = (x, y)

(−4, 123) = (x, y)

(3, 1) = (x, y)

(3,−6) = (x, y)

So,

y = ∛-(2 + x) + 1

y = ∛-(2 + 62) + 1

∛-1 = -1

y = -1∛64 + 1

y = -1 x 4 + 1

y = -4 + 1

y = -3

So,

(62, -3) ______(1)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 - 4) + 1

∛-1 = -1

y = ∛(-2 + 4) + 1

y = ∛2 + 1

y =  1.26 + 1

y = 2.26

So,

(-4, 2.26) _______(2)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 + 3) + 1

∛-1 = -1

y = -1∛5 + 1

y = -1 x 1.71 + 1

y = -1.71 + 1

y = -0.71

So,

(3, -0.71) _______(3)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 + 3) + 1

∛-1 = -1

y = -1∛5 + 1

y = -1 x 1.71 + 1

y = -1.71 + 1

y = -0.71

So,

Answer:

the circumference of the circle is about 23.55.

Step-by-step explanation:

hope this helps :D

Answer:

K-A would make a circle because it goes across

Answer:

See Below

Step-by-step explanation:

Slope is rise over run.

Rise is the difference in the y values

Run is the difference in the x values.

Rise/Run = 5 (slope)

You have both x values 4 from one point and 5 from the other point so the difference is 1.  The Run is equal to 1

So you now have Rise / 1 = 5

The first y value you have is 5 and based on (rise/1 = 5), you know the difference in the y values must equal 5.  That means the other y value has to be either 10 or 0.

0 will not work because that would make the slope negative since the line would slope downward from left to right.

Answer:

The question cut off but I'm assuming this is basically just a find the area of the shaded region type of question. First thing you need to do is calculate the areas of the right triangle and the rectangle. Subtract the area of the triangle from the area of the rectangle.

Area of rectangle: 8 x 7 = 56ft^2

Area of the triangle: (6 x 2)/2 = 6ft^2

Subtract 6ft^2 from 56ft^2 and you get:

56 - 6 = 50ft^2

Area of shaded region is 50ft^2

The Boolean expression that is not equivalent to the given expression "num * -1 ≥ 10" is option D: "NOT num * -1 < 10."

What is Boolean expression?

A Boolean expression is an expression or equation that evaluates to true or false. It includes the use of logical operators such as AND, OR, and NOT, as well as comparison operators such as equal to (=), greater than (>), less than (<), and more.

The Boolean expression that is not equivalent to the expression "num * -1 ≥ 10" is option D: "NOT num * -1 < 10."

Let's break down each option and evaluate its equivalence to the given expression:

A. (num < 0) AND (num * -1 = 10)

This expression checks if "num" is negative and if the absolute value of "num" is equal to 10. It does not directly represent the condition "num * -1 ≥ 10," so it is not equivalent.

B. (num < -10) OR (num = -10)

This expression checks if "num" is less than -10 or if "num" is exactly equal to -10. It also does not directly represent the condition "num * -1 ≥ 10," so it is not equivalent.

C. (num * -1 > 10) OR (num = -10)

This expression checks if the negative value of "num" is greater than 10 or if "num" is exactly equal to -10. Although it involves the negative value of "num," it represents the condition "num * -1 > 10" when "num" is positive. Therefore, it is equivalent to the given expression.

D. NOT num * -1 < 10

This expression checks if the negative value of "num" is not less than 10. While it involves the negative value of "num," it does not directly represent the condition "num * -1 ≥ 10." Additionally, the use of "NOT" operator flips the condition, which makes it different from the original expression. Hence, it is not equivalent.

Therefore, the Boolean expression that is not equivalent to the given expression "num * -1 ≥ 10" is option D: "NOT num * -1 < 10."

Therefore, the horizontal shift of 3 units to the right is achieved by subtracting 3 from the x-values in the equation.

To find the horizontal shift for the equation y = 3x + 4, we need to determine the change in the x-values or the shift in the x-direction.

In this case, the original equation is y = 3x + 4. To shift the graph 3 units to the right, we need to subtract 3 from the x-values.

The shifted equation will be y = 3(x - 3) + 4.

Answer:

x= -2

Step-by-step explanation:

First, write your equation with 8.5 substituted for y: 8.5= -3x +2.5

Next, subtract 2.5 from both sides to simplify the equation: 6= -3x

After that, divide both sides by -3 to get x by itself: -2 = x

So, when y=8.5, x=-2.

10 + 5y = 50,   y = 8 (years)

Step-by-step explanation:

5y  -  states. that Abraham still plans to visit.

10 + 5y = 50

5y = 50 - 10

5y = 40

y = 8

Answer: 10+5y=50; y=8 years

Step-by-step explanation:

Since Abraham has already visited 10 states, and he wants to visit 5 states per year, we get the equation 10+5y=50. The 10 is the number is states he has already visited. 5y represents the rate at which he visits the remaining states. 50 is the total amount of states.

To find the number of years, you get y alone.

10+5y=50

5y=40

y=8 years

The volume under the surface z = 1 + x² y²  and above the region enclosed by x = y²  and x = 4 is (19π - 12)/6. This can be calculated by setting up and evaluating a triple integral using cylindrical coordinates.

The question asks for the region above x = y² and below x = 4, which can be visualized as a parabolic cylinder. The surface z = 1 + x²y² can be plotted on top of this region to give a solid shape. To find the volume of this shape, we need to integrate the function over the region. We can set up the integral using cylindrical coordinates as follows:

V = ∫∫∫ z r dz dr dθ

where the limits of integration are:

0 ≤ r ≤ 2
0 ≤ θ ≤ π/2
y^2 ≤ x ≤ 4

Plugging in the equation for z and simplifying, we get:

V = ∫∫∫ (1 + r² cos² θsin² θ) r dz dr dθ

Evaluating the integral gives:

V = (19π - 12)/6


The volume under the surface z = 1 + x² y²  and above the region enclosed by x = y²  and x = 4 can be found by integrating the function over the given region using cylindrical coordinates. The limits of integration are 0 ≤ r ≤ 2, 0 ≤ θ ≤ π/2, and y² ≤ x ≤ 4. Plugging in the equation for z and evaluating the integral gives (19π - 12)/6 as the final answer.

The height of the tree stump is 2.48 feet.

To find the height of the tree stump, we can use the formula for the volume of a right cylinder: \(V = \pi r^2h\), where V represents the volume, r represents the radius, and h represents the height.

Given that the circumference of the tree stump is measured as 197 inches, we can use the formula for the circumference of a circle: C = 2πr, where C represents the circumference.

From the given circumference, we can solve for the radius, r, by dividing the circumference by 2π: r = C / (2π).

Plugging in the given circumference of 197 inches, we have: r = 197 / (2π) ≈ 31.416 inches.

Now, we can substitute the known values of the volume and radius into the volume formula: 92650 = π(31.416)^2h.

To solve for the height, h, we divide both sides of the equation by π(31.416)^2: h = 92650 / (π(31.416)^2) ≈ 29.74 inches.

Since we want to convert the height from inches to feet, we divide the height by 12: h = 29.74 / 12 ≈ 2.48 feet.

Therefore, the height of the tree stump is approximately 2.48 feet.
