6. The profit in dollars from the sale of x bicycles is given by

P(x) = -0.5x2 +200x - 14000 where 0 sxs 300

a) Find the change in profit when production is changed from 122 to 150 bicycles.

Answers

Answer:

$1792

Step-by-step explanation:

Step one:

given that the profit function is

[tex]P(x) = -0.5x^2 +200x - 14000[/tex]

let us find the profit when sale x=122

[tex]P(x) = -0.5(122)^2 +200(122) - 14000\\\\P(x)=-7442+24400-14000\\\\P(x)=2958[/tex]

Step two:

let us find the profit when sale x=150

[tex]P(x) = -0.5(150)^2 +200(150) - 14000\\\\P(x)=-11250+30000-14000\\\\P(x)=4750[/tex]

Hence the change is 4750-2958= $1792

What is the exact angle between the clock hands at 6:45:00 PM? Plz show work

Answers

Answer:

90°

Step-by-step explanation:

angle on a straight line=180 and half of 180=90°

Answer:

67.5°

Step-by-step explanation:

You know the long hand would be at number 9 and you also know that from the number 6 to 9 it would be 90°. Between each number, there are also 5 smaller marks on the clock. Thus, for 90°, there would be 5×3=15 smaller marks. (I used 3 because between 6 and 9 there are 3 big numbers)

Now here's the trickier part: There are 60 minutes within 5 small marks. We can find out at which mark does the shorter hand move to at 45 minutes.

[tex]\frac{45}{60}[/tex]×5 = 3.75

Out of the 15 smaller marks of 90°, the 45th minute stands at 3.75. The angle of 3.75 would then be between the 15th mark and the 3.75th mark. The gap would be 15-3.75 = 11.25 marks.

[tex]\frac{11.25}{15}[/tex] ×90° = 67.5°

You can refer to the picture for better visualisation of the clock. Hope this helps.

Remember that the quadratic formula is

A cardboard tube used for storing posters has the shape of a cylinder. It is 100 centimeters long and has a diameter of 8 canimeters. What is the volume of the tube

Answers

Answer:

[tex]Volume = 5028.6cm^3[/tex]

Step-by-step explanation:

Given

[tex]Height = 10cm[/tex]

[tex]Diameter = 8cm[/tex]

Required

Determine the volume

The volume of a cylinder is calculated as thus:

[tex]Volume = \pi r^2h[/tex]

Where [tex]r = radius[/tex]

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]r = \frac{1}{2} * 8cm[/tex]

[tex]r = 4cm[/tex]

[tex]h = 100cm[/tex]

Take

[tex]\pi = \frac{22}{7}[/tex], so we have

[tex]Volume = \pi r^2h[/tex]

[tex]Volume = \frac{22}{7} * 4^2 * 100[/tex]

[tex]Volume = \frac{22}{7} * 16 * 100[/tex]

[tex]Volume = \frac{22 * 16 * 100}{7}[/tex]

[tex]Volume = \frac{35200}{7}[/tex]

[tex]Volume = 5028.6cm^3[/tex]

7. Veronica is choosing between two health clubs.
After how many months will the total cost for
each health club be the same?

Answers

Answer:

The total cost for  each health club will be the same after 4 months.

Step-by-step explanation:

Let A = membership fee for studio AB = membership fee for studio Bx= membership month

[tex]A = 22 + 24.5x[/tex][tex]B = 47.00 + 18.25x[/tex]

We want to when the total cost at each health studio is the same.

In other words, when A = B.

Therefore, the expression becomes

[tex]A = B[/tex]

[tex]22\:+\:24.5x=47.00\:+\:18.25x[/tex]

Step 1: Simplify both sides of the equation.

[tex]24.5x+22=18.25x+47[/tex]

Step 2: Subtract 18.25x from both sides.

[tex]24.5x+22-18.25x=18.25x+47-18.25x[/tex]

[tex]6.25x+22=47[/tex]

Step 3: Subtract 22 from both sides.

[tex]6.25x+22-22=47-22[/tex]

[tex]6.25x=25[/tex]

Step 4: Divide both sides by 6.25

[tex]\frac{6.25x}{6.25}=\frac{25}{6.25}[/tex]

[tex]x=4[/tex]

Therefore, the total cost for  each health club will be the same after 4 months.

A sheet of metal 12 inches by 10 inches is to be used to make a open box. Squares of equal sides x are cut out of each corner then the sides are folded to make the box. Find the value of x that makes the volume maximum.


*Round to 2 decimal places and write out "inches"

Answers

Answer:

1.81 inches

Step-by-step explanation:

We are told that the sheet of metal to be used measures 12 inches by 10 inches.

Squares of equal sides x are cut out of each corner. Thus, it means total of 2x is cut of the 12 inches side and 10 inches side.

Thus;

Length; L = 12 - 2x

Width; W = 10 - 2x

Height; H = x

Volume of the box is;

V = LWH

V = (12 - 2x)(10 - 2x)x

Factorizing out, we have;

V = 4x[(6 - x)(5 - x)]

Equating V to zero, we can find the domain of the function;

At V = 0,

4x = 0; 6 - x = 0 ; 5 - x = 0

x = 0, x = 6, x = 5

The dimensions have to be positive. Thus;

0 ≤ x ≤ 5

Expanding the volume equation;

V = 4x[30 - 5x - 6x + x²]

V = 4x[30 - 11x + x²]

V = 4x³ - 44x² + 120x

dV/dx = 12x² - 88x + 120

Equating to zero to find the value of x that makes volume maximum;

12x² - 88x + 120 = 0

Using quadratic formula gives;

x = 1.81 or 5.52

From our domain, we have 0 ≤ x ≤ 5.

1.81 falls within the domain and therefore we will pick it as the height that makes the volume maximum.

Answer:1.81

What is the correct way to break 12 into parts and multiply each part by 6?

Answers

Answer:

By the use of algebra.

Step-by-step explanation:

You wish to break the quantity '12' into parts (number of parts not specified) and multiply each part by 6.

If you didn't want to break 12 into parts, the straight method would be to simply multiply 12 by 6.    12 × 6 = 72

Breaking 12 into 12 parts, you have

X₁, X₂, X₃, X₄, X₅, X₆, X₇, X₈, X₉, X₁₀, X₁₁, X₁₂

In this case, X₁ represents the first unit of the number 12.  X₂ represents the second unit of the number 12.   X₁₂ represents the last unit of the number 12.

Hence, X₁ + X₂ + X₃ + X₄ + X₅ + X₆ + X₇ + X₈ + X₉ + X₁₀ + X₁₁ + X₁₂ = 12

Each X value is the number 1; just that it's in 12 places and each case has a separate identity.

Each X value can then be multiplied by 6 and the sum of all would be 72.

The mean of birth weights for individual babies in the population is 3,500 grams. What is the mean birth weight for the sampling distribution for samples of 100 babies?

Answers

Answer:

The mean birth weight for the sampling distribution is

3,500 grams.

Step-by-step explanation:

The sample mean is the average of the sample values collected divided by the number of the samples, while the population mean is the average or mean of all the values in the population.  If the sample is random and the sample size is large enough, then the sample mean would be a good estimator of the population mean.  This implies that with a randomly distributed and unbiased sample size, the sample mean and population mean will be equal, according to the central limit theorem. Therefore, the mean of the sample means will always approximate the population mean.

3 people share a sum of money in a ration of 3:5:7 If one recieves 10 more than the other, what is the amount shared

Answers

Answer:

We have the ration:

3:5:7

This means that, if they receive $15, then:

Person A will get $3

Person B will get $5

Person C will get $10

Let's then define the amount of money shared as:

Amount = K*$15

where we want to find the number K.

In this scenario, each they will get:

Person A : $3*K

Person B: $5*K

Person C: $7*K

Now, we know that one of them gets "10 more than the other"

(The problem here is that we do not know exactly who receives more than who, i will suppose that person B receives $10 more than person A)

then we can have:

$5*K = $10 + $3*K

solving this for K, we have:

$5*K - $3*K = $10

$2*K = $10

K = $10/$2 = 5

Then the amount shared, in this situation, is:

Amount = K*$15 = 5*$15 = $75.

Harry wants a fence around his garden.
Height: 16.7m
Length: 16.3m
What is the perimeter of the whole garden?

Answers

Answer:

66m

Step-by-step explanation:

perimeter is the distance all round a figure

perimeter(p)= 2( length(l) + width(w))  or  perimeter= 2 length + 2 width

p= 2(l + w)                                                 or      p =  2l  + 2w

p= 2(16.3 +16.7)                                        or      p=  2(16.3) + 2(16.7)

p=2(33)                                                      or     p=   32.6  +  33.4

p=66m                                                        or     p=  66m

294.4 ft3
523.3 ft3
4186.7 ft3
104.7 ft3

Answers

Answer:

523.3ft³

Step-by-step explanation:

Given

Diameter, D = 10ft

Required

Determine the volume of helium it can hold.

To solve this, we simply calculate the volume of a sphere, which is:

V = 4/3πr³

Where

r = ½D

r = ½ * 10ft

r = 5ft

Substitute 5 for r in the stated formula and take π as 3.14

V = 4/3 * 3.14 * 5³

V = 4/3 * 3.14 * 125

V = ⅓(4 * 3.14 * 125)

V = ⅓ * 1570

V = 523.3 ft³

Hence, the sphere can contain 523.3ft³ of helium

Note: if a = b, then a + c = b + c
Therefore, -44x - 86 + 86 = -3 + 86

Next, divide both sides by -44, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c
