To calculate the number of containers that Heavey Compressors should be using, we need to determine the number of parts that need to be produced per day and divide it by the number of parts that can fit in each container.
100 parts per 8-hour day / 7 parts per container
= 14.2857 containers (round up to 15)
=15 containers
Therefore, Heavey Compressors be using 15 containers.
Maximum inventory levels = reorder point + reorder quantity – [minimum consumption × minimum lead time].
= 100+15-[12.5x8]
= 115-100
= 15
Therefore, the maximum system inventory for this part is 15.
The maximum stock position is the largest number of goods a company can store to give its guests with service at the smallest possible cost. It's vital to keep force control in line with demand.

Do any ingredients make up an equal amount of the smoothie? Construct a math argument to explain why or why not
Without knowing the specific ingredients and proportions used in a smoothie, it is impossible to definitively say whether any ingredients make up an equal amount. However, it is likely that the proportions of ingredients in a smoothie vary based on the desired taste, texture, and nutritional content.
For example, a smoothie may have more fruit than liquid to create a thicker consistency, or more liquid than fruit to create a thinner consistency. Additionally, the amount of sweeteners, such as sugar or honey, may vary based on personal preference and the natural sweetness of the fruit used.
In conclusion, without more specific information about the ingredients and proportions used in a particular smoothie, it is not possible to determine whether any ingredients make up an equal amount. The proportions of ingredients in a smoothie are likely to vary based on various factors and personal preference.

Find all other zeros of P(x)=x^3-6x^2+18x-40 , given that 1+3i is a zero.
Answer:
1 - 3i, 4
Step-by-step explanation:
The polynomial has real coefficients, so if it has a complex root, it must have at least two complex roots which are complex conjugates.
Since 1 + 3i is a root, then 1 - 3i is also a root.
Two of the factors of the polynomial are:
x - (1 + 3i) and x - (1 - 3i)
Simplify the factors above:
x - 1 - 3i and x - 1 + 3i
Find their product:
(x - 1 - 3i)(x - 1 + 3i) =
Rewrite them showing we have the product of a sum and a difference.
= [(x - 1) - 3i][(x - 1) + 3i]
Multiply the factors above noticing they are a sum and a difference which follows the pattern (a + b)(a - b) = a² - b².
= (x - 1)² - (3i)²
= x² - 2x + 1 - 9(-1)
= x² - 2x + 10
Now we divide the original polynomial by the product we just found using long division.
x - 4
------------------------------
x² - 2x + 10 | x³ - 6x² + 18x - 40
- x³ - 2x² + 10x
------------------------
-4x² + 8x - 40
- -4x² + 8x - 40
--------------------------
0 + 0 + 0
Now we know that x³ - 6x² + 18x - 40 factors into (x² - 2x + 10)(x - 4).
(x² - 2x + 10)(x - 4) = 0
From x² - 2x + 10, we have roots x = 1 + 3i and x = 1 - 3i.
x - 4 = 0
x = 4
From x - 4, we have root x = 4.

The rate of change of the temperature during the hour and a half after the beginning of a thunderstorm is given by T(h) = 9.43 h^3 − 15.41h^2 + 17.34h − 9.83T(h) = 9.43h^3- 15.41h^2 + 17.34h − 9.83where output is measured in per hour and h is the number of hours since the storm began.(a) Evaluate ∫1.5 T(h)dh. ∫0 Tb(h)dh0 1.5(Round your answer to three decimal places.)(b) Interpret the answer to part (a)
∫1.5 T(h) dh = 9.573, rounded to three decimal places. (a) To evaluate ∫1.5 T(h) dh, we need to integrate T(h) with respect to h from 0 to 1.5: ∫1.5 T(h) dh = ∫0.1.5 (9.43h^3 - 15.41h^2 + 17.34h - 9.83) dh
Using the power rule of integration, we can integrate each term of the polynomial: ∫0.1.5 (9.43h^3 - 15.41h^2 + 17.34h - 9.83) dh
= (9.43/4)h^4 - (15.41/3)h^3 + (17.34/2)h^2 - 9.83h |0.1.5
= [(9.43/4)(1.5)^4 - (15.41/3)(1.5)^3 + (17.34/2)(1.5)^2 - 9.83(1.5)] - [(9.43/4)(0)^4 - (15.41/3)(0)^3 + (17.34/2)(0)^2 - 9.83(0)] = 9.573
Therefore, ∫1.5 T(h) dh = 9.573, rounded to three decimal places.
(b) The answer to part (a) represents the total change in temperature during the hour and a half after the beginning of the thunderstorm. This means that the temperature increased by an average of 9.573 degrees per hour during this time period.
This integral gives us a measure of the total effect of the thunderstorm on the temperature, which is useful for predicting the weather and understanding the behavior of natural phenomena.

A parachutist whose mass is 100 kg drops from a helicopter hovering 3000 m above the ground and falls under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with proportionality constant b3 = 20 N-sec/m when the chute is closed and b4 = 100 N-sec/m when the chute is open. If the chute does not open until 30 sec after the parachutist leaves the helicopter, after how many seconds will he hit the ground? If the chute does not open until 1 min after he leaves the helicopter, after how many seconds will he hit the ground?
If the chute does not open until 1 min after he leaves the helicopter, then the equation to calculate the seconds it will he hit the ground is (1/2)mv² + ∫ F(v) dv = 0
The force due to air resistance is assumed to be proportional to the velocity of the parachutist, and we will use this information to determine the time it takes for the parachutist to reach the ground with and without a chute.
The force of air resistance is proportional to the velocity of the parachutist. This means that the larger the velocity, the larger the force of air resistance.
As the velocity increases, the force of air resistance also increases, which reduces the kinetic energy. When the chute opens, the force of air resistance increases even more, which further reduces the kinetic energy and slows down the parachutist.
To determine the time it takes for the parachutist to hit the ground, we can use the following equation:
PE + KE + work done by air resistance = PE + KE
where PE is the gravitational potential energy, KE is the kinetic energy, and work done by air resistance is the work done by the force of air resistance.
When the chute is closed, we can write:
mgh = (1/2)mv² + ∫ F(v) dv
where m is the mass of the parachutist, g is the acceleration due to gravity, h is the height of the helicopter above the ground, and the integral is taken over the velocity range from 0 to v.
Similarly, when the chute is open, we can write:
mgh = (1/2)mv² + ∫ F(v) dv
where b = b4 and the integral is taken over the velocity range from 0 to v.
To solve for the time it takes for the parachutist to hit the ground, we need to determine the velocity at which he hits the ground. This is the velocity where KE = 0, and we can find it by equating the expressions for KE and work done by air resistance when the parachutist hits the ground:
(1/2)mv² + ∫ F(v) dv = 0
We can solve these equations numerically to find the time it takes for the parachutist to hit the ground with and without the chute.

This function is continuous everywhere, as the limit of sinx/x as x approaches 0 is 1, and f(0) = 1. It cannot be extended to a larger domain, as it is already continuous everywhere.
For example, when x = 0.1, f(x) = 0.998334166, and when x = 0.001, f(x) = 0.998999667.This function is continuous everywhere, as the limit of sinx/x as x approaches 0 is 1, and f(0) = 1. This means that there are no breaks or discontinuities in the function, and it is continuous everywhere. To demonstrate this, we can look at specific values of x. For example, when x = 0.1, f(x) = 0.998334166, and when x = 0.001, f(x) = 0.998999667. This shows that the function is smoothly transitioning from one value to the next, and is therefore continuous everywhere. The function cannot be extended to a larger domain, as it is already continuous everywhere. This means that the function is defined everywhere on its domain, and there is no need to extend it.

we can conclude that the value of n for which [tex]t_n[/tex] = 0.3325 is between 3 and 4 and the value of n for which [tex]S_n[/tex]= -6 is 6.
How to find value of n and sum of sequence?A) To find the value of n for which [tex]t_n[/tex] = 0.3325, we can use trial and error method.
Starting with n=1, we have:
[tex]t_1 = (1^2 - 1)/(3 * 1^2) = 0[/tex]
For n=2, we have:
[tex]t_2 = (2^2 - 1)/(3 * 2^2) = (3)/(12) = 0.25[/tex]
For n=3, we have:
[tex]t_3 = (3^2 - 1)/(3 * 3^2) = (8)/(27) = 0.296296...[/tex]

Thus, we can conclude that the value of n for which [tex]t_n[/tex] = 0.3325 is between 3 and 4, and it can be found more accurately by using numerical methods such as bisection or Newton's method.
B) To find the sum of the arithmetic series 16 + 13 + 10 + ..., we can use the formula for the sum of an arithmetic series:

Let's assume that the nth term is represented by [tex]a_n = 16 - 3 * (n - 1),[/tex] so that a_1 = 16 and a_n = 16 - 3 * (n - 1).
Then, we have:
S_n = n/2 * (16 + 16 - 3 * (n - 1)) = n/2 * (16 + 16 - 3n + 3) = n/2 * (16 + 16 - 3n + 3) = n/2 * (32 - 3n + 3) = 16n - (3/2)n^2 + (3/2)n
We want to find the value of n for which S_n = -6, so we can substitute the value of S_n into the equation and solve for n:
[tex]S_n = n/2 * (16 + 16 - 3 * (n - 1)) = n/2 * (16 + 16 - 3n + 3) = n/2 * (16 + 16 - 3n + 3) = n/2 * (32 - 3n + 3) = 16n - (3/2)n^2 + (3/2)n[/tex]
[tex]-6 = 16n - (3/2)n^2 + (3/2)n[/tex]
Expanding the equation and solving for n, we find that n = 6.
Thus, the value of n for which [tex]S_n[/tex]= -6 is 6.

Given that a family wants to rent a car to go on vacation. Company A charges $55.50 and 16 cents per mile. Company B charges $50.50 and 9 cents per mile.
The expression for the charges by company A is,
C = 16x + 55.50
The expression for the charges by company B,
C = 9x + 55.50
The amount of company A more than company B is calculated as:-
Amount = ( 16 + 55.50) - ( 9 + 55.50 )
Amount = 71.50 - 64.50
Amount = $7
Hence, company A will charge $7 more.

An office manager believes that the percentage of employees arriving late is even greater than the previously claimed 7%. She conducts a hypothesis test on a random 200 employee arrivals and finds 23 punching in late. Is this strong evidence against the 0.07 claim?
answer choices
Yes, p-value is 0.0062
Yes, p-value is 2.5
No, p-value is only 0.0062
No, p-value is over 0.10
There is insufficient information to reach a conclusion.
We do not have strong evidence against the 0.07 claim so, the correct answer is: No, the p-value is over 0.10.
Let's calculate the p-value and compare it to the level of significance (alpha) to determine if there is strong evidence against the 0.07 claim.
Let p be the true proportion of employees arriving late. The null hypothesis is that p = 0.07 and the alternative hypothesis is that p > 0.07.
The sample proportion of employees arriving late is x/n = 23/200 = 0.115. Under the null hypothesis, the sampling distribution of the sample proportion follows a normal distribution with a mean of 0.07 and standard deviation [tex]\sqrt{((0.07 * 0.93) / 200)}[/tex] = 0.0319.
The z-score corresponding to the sample proportion is (0.115 - 0.07) / 0.0319 = 1.41. The p-value is the probability of observing a z-score greater than or equal to 1.41 under the null hypothesis, which can be calculated as P(Z >= 1.41) = 0.078.
Since the p-value is greater than the level of significance alpha (which is typically 0.05 or 0.01), we fail to reject the null hypothesis that the true proportion of employees arriving late is 0.07.
Therefore, we do not have strong evidence against the 0.07 claim so, the correct answer is: No, the p-value is over 0.10.

Find the radius of a sphere with a volume of 26, 244π cubic inches.
27 inches is the radius of a sphere with a volume of 26, 244π cubic inches.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that volume of a sphere is 26, 244π cubic inches.
We need to find the radius of sphere.
V=4/3πr³
26, 244π=4/3πr³
26, 244=1.333r³
Divide both sides by 1.333
26,244/1.333=r³
19688=r³
Cube root on both sides
∛19688 = r
27=r
Hence, 27 inches is the radius of a sphere with a volume of 26, 244π cubic inches.
