The probability of choosing sausage and onion by Rosa's mom from the given 8 different toppings as per given condition is equal to

(1/ ⁸C₂).

As given in the question,

Total number of different toppings = 8

Number of different toppings choose by Rosa's mom randomly = 2

Possibility of choosing sausage and onion (any one) = 1

Total number of outcomes = ⁸C₂

Number of favorable outcomes = 1

Probability of choosing sausage and onion ( exactly ) one topping

= ( Number of favorable outcomes ) / ( Total number of outcomes )

= ( 1/⁸C₂ )

Therefore, the probability when Rosa's mom chooses sausage and onion out of 8 toppings is equal to ( 1/⁸C₂ ).

The above question is incomplete, the complete question is:

The derivative of f(x) is f'(x) = cosh(x) + x sinh(x) + 5 cosh(x).

The function f(x) = x cosh(x) + 5 sinh(x) is given. To find its derivative f'(x), we use the rules of differentiation.

First, we differentiate the term "x cosh(x)" using the product rule. The derivative of x with respect to x is 1, and the derivative of cosh(x) with respect to x is sinh(x). So, the derivative of x cosh(x) is cosh(x) + x sinh(x).

Next, we differentiate the term "5 sinh(x)" using the chain rule. The derivative of sinh(x) with respect to x is cosh(x). Multiplying it by the constant 5 gives us 5 cosh(x).

Finally, we add the derivatives of the two terms: f'(x) = cosh(x) + x sinh(x) + 5 cosh(x).

Therefore, the derivative of f(x) is f'(x) = cosh(x) + x sinh(x) + 5 cosh(x).

Since, Alice ate 5 cookies and 2 carrots for a total of 590 calories; bob ate 3 cookies and 4 carrots for a total of 410 calories. Therefore, In a cookie there are 110 calories.

A calorie is a unit of energy that food and drink provide. we can usually find out how many calories are listed in foods, and wearables like the best fitness trackers let you monitor how many calories you're burning in different activities. Certain foods, such as processed foods, tend to be high in calories. Other foods, such as fresh fruits and vegetables, tend to be low in calories. there is not. Calories are needed to give you enough energy to move, keep warm, grow, work, think, and play. Our circulation and digestion also need to work well with the energy we get from calories.

Let x = calories in cookies.

     y = calories in carrots.

Now, according to the question:

     5x + 2y = 590                   --------------------------------------- (1)

     3x + 4y = 410                    -------------------------------------- (2)

Multiplying equation(1) by 3 and equation(2) by 5:

         15x + 6y = 1770                       ---------------------------(3)

         15x + 20y = 2050                   ---------------------------(4)

Solving we get:

    y = 280/14

or, y = 20 units.

Putting the value of y = 20 in equation (2)

    3x + 4y = 410

⇒  3x + 4 × 20 = 410

⇒ 3x = 410 - 80

⇒ x = 330/3

⇒ x = 110 Units

Therefore, the calories of cookies is 110 units .

To evaluate the given integral using Green's theorem, we need to express it in the flux form.  The result of the integral is -r/6.

Green's theorem states that for a region R bounded by a simple closed curve C, the flux of the vector field F = (P, Q) across C is equal to the double integral of the curl of F over R.

In this case, we have the vector field F = (r^2xy, 1/2y^3), where r is the position vector (x, y).

The flux form of Green's theorem is:

\(∫∫R (curl F) · dA = ∫∫R (∂Q/∂x - ∂P/∂y) dA\)

Let's calculate the curl of F:

∂Q/∂x = 0

∂P/∂y = 2rxy

So, the curl of F is given by\((∂Q/∂x - ∂P/∂y) = 0 - 2rxy = -2rxy.\)

Now, let's evaluate the integral using the flux form of Green's theorem:

∫∫R (-2rxy) dA

Since the region R is a triangle with vertices (0,0), (1,0), and (0,1), we can express it as:

\(R = {(x, y) | 0 ≤ x ≤ 1, 0 ≤ y ≤ 1 - x}\)

Now, we can rewrite the integral:

\(∫₀^(1-x) (-2rxy) dy = -2rxy²/2 ∣₀^(1-x) = -rxy² ∣₀^(1-x) = -r(x-x²)\)

Let's evaluate the inner integral first:

\(∫₀^(1-x) (-2rxy) dy = -2rxy²/2 ∣₀^(1-x) = -rxy² ∣₀^(1-x) = -r(x-x²)\)

Now, evaluate the outer integral:

\(∫₀¹ -r(x-x²) dx = -r(x²/2 - x³/3) ∣₀¹ = -r(1/2 - 1/3) = -r(3/6 - 2/6) = -r(1/6) = -r/6\)

Therefore, the result of the integral is -r/6.

Answer:

24.997

Step-by-step explanation:

Let's start with the easy parts of the perimeter...the flat parts...7 + 7 = 14. We'll add that to the arch shortly.

We need to find the circumference of the whole circle, then divide by 4 to get 1/4 of a circle. (There might be a faster way, but this gets the job done.)

circumference = (2)(pi)(r)

= 2(3.142)(7) = 43.988

Now divide that by 4 for the distance of the arch.

43.988/4 = 10.997

Add that to the flat parts

10.997 + 14 = 24.997

Please let me know if you have any questions.

To find the y-coordinate of point P on the unit circle, given that its x-coordinate is 5/13, we can utilize the Pythagorean identity for points on the unit circle.

The Pythagorean identity states that for any point (x, y) on the unit circle, the following equation holds true:

x^2 + y^2 = 1

Since we are given the x-coordinate as 5/13, we can substitute this value into the equation and solve for y:

(5/13)^2 + y^2 = 1

25/169 + y^2 = 1

To isolate y^2, we subtract 25/169 from both sides:

y^2 = 1 - 25/169

y^2 = 169/169 - 25/169

y^2 = 144/169

Taking the square root of both sides, we find:

y = ±sqrt(144/169)

Since we are dealing with points on the unit circle, the y-coordinate represents the sine value. Therefore, the y-coordinate of point P is:

y = ±12/13

So, the y-coordinate of point P can be either 12/13 or -12/13.

By subtracting the sum of the two known angles from 180, we can find the measure of the unknown angle. In this example, the size of angle ABC is 105 degrees.

105 degrees

To find the size of angle ABC, use the formula 180 - (A + B) = C.

A = 30 degrees

B = 45 degrees

Therefore, C = 180 - (30 + 45) = 105 degrees

Therefore, the size of angle ABC is 105 degrees to the nearest degree.

To find the size of angle ABC, use the formula 180 - (A + B) = C. In this case, A = 30 degrees and B = 45 degrees. Therefore, C = 180 - (30 + 45) = 105 degrees. The size of angle ABC is then 105 degrees, rounded to the nearest degree. This can be useful when trying to calculate the measure of an angle in a triangle.

Subtract 2 from both sides:

\(8m+2-2=12+8m-2\)

\(8m=8m+10\)

Subtract 8m from both sides:

\(8m-8m=8m+10-8m\)

\(0=10\)

Since both sides are not equal, there is no solution, because the value of m will not affect this end result of \(0=10\) which is false.

Those two trains met 4 hours after 1 pm or at 5 pm. They met at 350 miles from train A's starting point.

The relation between distance, speed, and time is given by:

distance = speed x time

In the given problem:

Train A leaf at 12.00 pm, with

speed = 70 mph

Since train B left at 1 pm, by the time train B left, train 1 has travelled a distance of:

distance train A = 70 mph x 1 hour = 70 miles.

Hence, when train A and train B left at 1 pm, they are 550 - 70 = 480 miles apart.

Let

sA = distance travelled by train A since 1 pm

sB = distance travelled by train B since 1 pm

Hence,

sA = 70 t

sB = 50 t

When they met:

sA + sB = 480

70t + 50t = 480

120t = 480

t = 480/120 = 4 hours

Therefore, the met at 5 pm. At that time, train A has travelled 5 hours and its position is:

distance = 70 x 5 = 350 miles from its starting point.

The exact value of the area under the graph of f(x) over the interval [a,b] is False.

If f(x) is a constant function, meaning it has the same value for all x, then the graph of f(x) over the interval [a, b] will be a horizontal line.

The area under a constant function over any interval is simply the product of the constant value and the width of the interval.

However, the formula for the area of a rectangle is not applicable in this case because the graph of a constant function does not form a rectangle.

The area under a constant function is a rectangle only when the function is a constant height (y-value) over the entire interval, which is not the case for arbitrary constant functions.

To compute the exact value of the area under the graph of f(x) over the interval [a, b] when f(x) is a constant, you simply need to multiply the constant value by the width of the interval, which is (b - a).

She should use 16 quarts of sand for obtaining total of 52 quarts of mixture. The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

All real numbers are believed to be explicable by the four fundamental operations, sometimes known as "arithmetic operations." Mathematics places operations such as quotient, product, sum, and difference after operations such as division, multiplication, addition, and subtraction.

We are given that with every 1\(\frac{1}{2}\) quarts of potting soil,, two-thirds quart of sand is to be mixed.

So, from this we get

Total mixture = 1\(\frac{1}{2}\) + \(\frac{2}{3}\)

Total mixture = \(\frac{13}{6}\) quarts

Now, on dividing sand and total mixture by 13, we get

\(\frac{2}{39}\) quarts of sand produces in total \(\frac{1}{6}\) quarts of mixture.

Now, on multiplying sand and total mixture by 6, we get

\(\frac{12}{39}\) quarts of sand produces in total 1 quarts of mixture.

So,

⇒ For 52 quarts of mixture = \(\frac{624}{39}\) quarts of sand

⇒ For 52 quarts of mixture = 16 quarts of sand

Hence, she should use 16 quarts of sand for obtaining total of 52 quarts of mixture.
