a. Find the additional cost incurred in dollars when production is increased from 2 units to 15 units.
b. If ​C(2​)=267​, determine ​C(15​) using your answer in ​(a).

Answer: B: N is odd

Step-by-step explanation:

If 3N + 5 is a multiple of 10, then it can be written as:

3N + 5 = 10k, where k is an integer.

Subtracting 5 from both sides, we get:

3N = 10k - 5

Dividing both sides by 3, we get:

N = (10k - 5) / 3

For N to be an integer, 10k - 5 must be divisible by 3.

We know that any multiple of 10 that is divisible by 3 must have a units digit of 0, and the sum of its digits must be divisible by 3.

The units digit of 3N + 5 is 5, which is not 0, so N is not even. Therefore, option A is not correct.

The sum of the digits of 3N + 5 is 3 + 5 = 8, which is not divisible by 3. Therefore, N is not a factor of 30. Therefore, option C is not correct.

Similarly, since 3N + 5 is not divisible by 5, N cannot be a factor of 50. Therefore, option D is not correct.

Therefore, the only possible option is B: N is odd.

To see why, consider the following: if N is odd, then 3N is odd, and 3N + 5 is even. If 3N + 5 is even, then it must be divisible by 2, which means it is also divisible by 10 (since it is given that 3N + 5 is a multiple of 10). Therefore, N must be odd.

The volume of the solid of revolution is approximately 2.470 cubic unit.

To find the volume of the solid of revolution, we need to use the formula:

V = π∫[a,b] [tex]y^2[/tex] dx

where y is the distance between the function that is being rotated and the axis of revolution, which in this case is the y-axis.

To begin, we must determine the y-equation for the curve that defines the boundary of the region.

y = (1/2)x cosh x

Solving for x in terms of y, we get:

x = [tex]cosh^{-1}[/tex](2y/y)

We only need to find the volume for the region where y is not negative and then multiply the result by 2 because the curve is symmetric with respect to the y-axis.

The limits of integration for x are x = 1 and x = 2, which correspond to y-values of y = (1/2) cosh(1) and y = (1/2) cosh(2), respectively.

So, we can write the integral for the volume as:

V = 2π∫[[tex]0,(1/2)cosh(2)] [(cosh^{-1}(2y/y))^2] dy[/tex]

We can simplify this by using the identity [tex]cosh^{-1}(x) = ln(x + \sqrt{x^2 - 1}),[/tex] which gives:

V = 2π∫[[tex]0,(1/2)cosh(2)] [(ln(2y/y +\sqrt{((2y/y)^2 - 1)))^2}] dy[/tex]

This integral can be evaluated using integration by parts or numerical methods. Using numerical methods, we get:

V ≈ 2.470 cubic units (rounded to three decimal places)

Therefore, the volume of the solid of revolution is approximately 2.470 cubic unit.

Answer: 114

Step-by-step explanation:

If x-3 is a factor of 5x³ - 3x² + 2x - k, then x = 3 is a root of the polynomial. This means that when x = 3, the polynomial is equal to zero.

Substituting x = 3 into the polynomial, we get:

5(3)³ - 3(3)² + 2(3) - k = 0

Simplifying this expression, we get:

135 - 27 + 6 - k = 0

Solving for k, we get:

k = 135 - 27 + 6 = 114

Therefore, the value of k is 114.

Answer:

give brainliest if correct

Step-by-step explanation:

Let's call the distance from the ball to the base of the goal "x". We can use the tangent function to set up an equation:

tan(27°) = opposite/adjacent

In this case, the opposite side is the height of the goal (9 feet) and the adjacent side is the distance we want to find (x). So we can rewrite the equation as:

tan(27°) = 9/x

To solve for x, we can cross-multiply and then divide by tan(27°):

tan(27°) * x = 9

x = 9 / tan(27°)

Using a calculator, we get:

x ≈ 17.20 feet

So the distance from the ball to the base of the goal is approximately 17.20 feet.

The set of parametric equations for the path of the baseball are:

x = (146.67 cos )t

y = 3 + (146.67 sin )t - 16t

where x is the horizontal distance traveled by the ball and y is the vertical height of the ball.

It should be noted that to determine if the ball clears the fence, we need to find the value of t when y = 10, which is the height of the fence. So we solve the equation:

3 + (146.67 sin 220)t - 16t = 10

Simplifying the equation, we get:

(146.67 sin 220 - 16)t = 7

t = 7 / (146.67 sin 220 - 16) ≈ 0.071 seconds

Now we can plug this value of t into the equation for x to find the horizontal distance traveled by the ball:

x = (146.67 cos 220) × 0.071 ≈ -24.4 feet

Since the ball has a negative x-coordinate, it lands behind the fence and is not a homerun.

c) The graph shows the path of the baseball in blue. The important points are labeled on the graph. The point (0,3) represents the initial position of the ball, and the point where the blue curve intersects the red line (y=10) represents the point where the ball hits the top of the  fence.

Answer:

En este problema se trata de una función exponencial, donde la cantidad de microbios en el recipiente se duplica cada minuto.

Si x representa el número de minutos transcurridos y y la cantidad de microbios en el recipiente, entonces se puede expresar la función exponencial como:

y = a * (2)^x

Donde "a" es la cantidad inicial de microbios en el recipiente, en este caso a = 1.

Después de 30 minutos, la cantidad de microbios en el recipiente es:

2^30 = 1,073,741,824

Esto significa que si se coloca un solo microbio en el recipiente, se tardará 30 minutos en llenarlo.

Si se colocan 2 microbios en el recipiente, entonces la cantidad inicial de la función exponencial es a = 2, y se busca el valor de x tal que:

2 * (2)^x = 1,073,741,824

Dividiendo ambos lados por 2, se tiene:

(2)^x = 536,870,912

Tomando logaritmos base 2 en ambos lados, se tiene:

x = log2(536,870,912) = 29

The system of inequalities has the following solution set as a result: -1, 0, 1, 2, 3.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the not equal sign (=) to indicate that two values are not equal. whenever several inequalities are use to compare the numbers, whether it is less than or greater than sign. This topic will cover the different inequality ,methods properties and symbols for solving linear inequalities in one variable and two variables that are used in algebra.

A finite set of equations for which common solutions are referred to in mathematics as a set of simultaneous equations, are  known as a system of equations or an equation system.

First of all  for first inequalities ,

we must first subtract 2 from both sides of the inequality 2-6 y <14.

-6 y < 12

now , we are dividing -6 both sides,

than the inequality symbol must be reversed:

than we get

y > -2

Hence, y > -2 is the solution set for the first inequality.

For second inequalities Now  we  first subtract 21 from both sides of the inequality

than we get,

-5 y > -20

The next step is to divide -5 by both sides.  

than, the inequality symbol must be reversed:

than we get

y < 4

The second inequality's solution set is therefore y 4.

We can contain all the integers between -2 and 4 (inclusive) to discover the integers in the solution set for both inequalities:

-2, -1, 0, 1, 2, 3, 4

In this set , the integers that fulfill both inequalities are

-1, 0, 1, 2, 3

The expected value is ((18/37) x (2 x wager [we will receive the wager back and the winnings])) + ((19/37) x 0)

What is American roulette?

Guessing on which number on the wheel ball will come to rest is the objective of American Roulette. Every number contains the same chances as any other number of coming up on each spin (that is winning number on any spin has no effect on the outcome of next spin). The best chance of payout is provided by an outside bet. The possible outcomes of the game of roulette is covered by 'outside bets'. With the higher winning chances, the payout is not going to be incredibly generous(it's only 1:1 for bets like odd or even that covers almost like half the wheel).

Expected value is calculated by adding all the different possible outcomes multiplied by their probabilities.  

So, in this case (0.5 x $2) + (0.5 x $1).  

For specific example it would be determined by the number of options on a roulette wheel (generally 37).  

So winning on this bet in 18 outcomes (the even numbers) and losing on 19 outcomes (the odd numbers + 0).  

Putting it all together, the expected value is ((18/37) x (2 x wager [we will receive the wager back and the winnings])) + ((19/37) x 0).
