Answers

Answer 1

Able Cable offers the fastest mean downloading speed among the three providers with a speed of 4.0 Mbps.

How to determine the fastest internet provider?

We can calculate the mean (average) download speed for each provider and compare them to determine which company offers the fastest mean downloading speed.

Based on the given data, the mean download speed for each provider is:

City Net: (3.6 + 3.7 + 3.7 + 3.6 + 3.9) / 5 = 3.7 megabits per second (Mbps)

Able Cable: (3.9 + 3.9 + 4.1 + 4.0 + 4.1) / 5 = 4.0 Mbps

Tel-N-Net: (3.9 + 3.7 + 4.0 + 3.6 + 3.8) / 5 = 3.8 Mbps

Therefore, Able Cable offers the fastest mean downloading speed among the three providers with a speed of 4.0 Mbps.

Answers

When the base of a triangle is doubled, the height must be halved to maintain the same area. This is because the area of a triangle is proportional to the product of its base and height. Area of the new triangle is b₁h₂.

Given that a triangle has base b and height h, and the base is doubled. We need to find how the height must change so that the area remains the same.

The area of the original triangle is (1/2) b₁h₁.

Let's assume that the original base is b₁ and the original height is h₁.

Now, the base is doubled, so the new base is 2b₁.

Using the formula for the area of a triangle, we can find the area of the new triangle as

Area of the new triangle = (1/2) × base × height

= (1/2) × 2b₁ × h₂

= b₁h₂

where h₂ is the new height of the triangle.

Since we want the area of the new triangle to be equal to the area of the original triangle, we can equate the two expressions for the area

b₁h₁ = b₁h₂

Simplifying, we get

h₂ = h₁/2

Therefore, the height must be halved when the base is doubled to keep the area of the triangle constant.

The critical number of the function f(x) = 5x2 + 7x – 10 is The function f(x) = -2x3 + 39x2 – 240x + 2 has two critical numbers A < B with A = and B =

Answers

The critical numbers of f(x) = -2x^3 + 39x^2 - 240x + 2 are A = 5 and B = 8.

To find the critical numbers of a function, we need to find the values of x where the derivative of the function is zero or undefined.

For the function f(x) = 5x^2 + 7x - 10, the derivative is:

f'(x) = 10x + 7

To find the critical numbers, we need to set f'(x) = 0 and solve for x:

10x + 7 = 0

10x = -7

x = -7/10

So the critical number of f(x) = 5x^2 + 7x - 10 is x = -7/10.

For the function f(x) = -2x^3 + 39x^2 - 240x + 2, the derivative is:

f'(x) = -6x^2 + 78x - 240

To find the critical numbers, we need to set f'(x) = 0 and solve for x:

-6x^2 + 78x - 240 = 0

We can simplify this equation by dividing both sides by -6:

x^2 - 13x + 40 = 0

Now we can factor the quadratic:

(x - 5)(x - 8) = 0

So the solutions are x = 5 and x = 8.

To determine which critical point is A and which is B, we need to check the sign of the second derivative of f(x) at each critical point.

The second derivative of f(x) is:

f''(x) = -12x + 78

Plugging in x = 5, we get:

f''(5) = -12(5) + 78 = 18

Since f''(5) is positive, we know that f(x) has a local minimum at x = 5. Therefore, x = 5 is the critical point A.

Plugging in x = 8, we get:

f''(8) = -12(8) + 78 = -6

Since f''(8) is negative, we know that f(x) has a local maximum at x = 8. Therefore, x = 8 is the critical point B.

Therefore, the critical numbers of f(x) = -2x^3 + 39x^2 - 240x + 2 are A = 5 and B = 8.

Los 2/3 mas la edad de Juan es igual a los 3/5 menos la edad de Julia. ¿Que fraccion representa la edad de juan respecto a la edad de Julia?

Answers

The fraction representing Juan's age relative to Julia's age is -1/10. This means that Juan's age is one-tenth less than Julia's age.

Let's start by translating the given statement into an equation:

[tex]2/3J = 3/5 - 2/3Jl[/tex]

where J is Juan's age and Jl is Julia's age.

Now we can simplify this equation by first multiplying both sides by 15 (the least common multiple of 3 and 5) to get rid of the denominators:

[tex]10J = 9 - 10Jl[/tex]

Next, we can isolate J on one side of the equation by adding 10Jl to both sides:

[tex]10J + 10Jl = 9[/tex]

Finally, we can factor out a 10 from the left-hand side:

[tex]10(J + Jl) = 9[/tex]

Dividing both sides by 10, we get:

[tex]J + Jl = 9/10[/tex]

Now we can express Juan's age as a fraction of Julia's age by dividing both sides of this equation by Jl:

[tex]Jl/Jl + J/Jl = 9/10Jl[/tex]

Simplifying this, we get:

1 + J/Jl = 9/10

Subtracting 1 from both sides, we get:

[tex]J/Jl = 9/10 - 1[/tex]

[tex]J/Jl = -1/10[/tex]

Answers

The total expenditure for raising the poultry farm is GHC 5458.60.

To calculate the total expenditure for raising the poultry farm, you need to sum up all the expenses:

1. Cost of 3 large coops at GHC650 each:

  Total cost of coops = 3 coops * GHC650/coop

                                   = GHC1950

2. Cost of 1500 day-old chicks at GHC75 for 100 chicks:

  Total cost of chicks = (1500 chicks / 100 chicks) * GHC75

                                   = GHC1125

3. Cost of 1000 bags of feed at GHC1.75 per bag:

  Total cost of feed = 1000 bags * GHC1.75/bag

                                 = GHC1750

4. Transport cost for conveying the 1000 bags of feed at 50gp (GHC 0.50) per bag:

  Total transport cost = 1000 bags * GHC0.50/bag

                                    = GHC500

5. Cost of drugs and vaccines at GHC120:

6. Other expenses amounted to GHC13.60.

Now, add up all these expenses to find the total expenditure:

= Cost of coops + Cost of chicks + Cost of feed + Transport cost + Cost of drugs and vaccines + Other expenses

= GHC1950 + GHC1125 + GHC1750 + GHC500 + GHC120 + GHC13.60

= GHC5458.60

Answers

The function f(x) = -4x² + 12x - 4 attains an absolute maximum of 3 at x = 1/2 and an absolute minimum of -8 at x = 2 on the interval [1/2, 2].

To help you verify and find the absolute maximum and minimum values of the function f(x) = -4x² + 12x - 4 on the interval [1/2, 2].

Step 1: Find the critical points by taking the derivative of f(x) and setting it to 0.
f'(x) = -8x + 12

Step 2: Solve f'(x) = 0 to find critical points.
-8x + 12 = 0
x = 3/2

Step 3: Evaluate the function f(x) at the critical point and the interval's endpoints.
f(1/2) = -4(1/2)^2 + 12(1/2) - 4(1/2) = 3
f(3/2) = -4(3/2)^2 + 12(3/2) - 4(3/2) = 1
f(2) = -4(2)^2 + 12(2) - 4(2) = -8

Step 4: Compare the function values and determine the absolute maximum and minimum values.
The absolute maximum value is 3 at x = 1/2.
The absolute minimum value is -8 at x = 2.

amount of time it takes to drive the route.



what's a reasonable domain and range?

Answers

In this scenario, the domain would be the set of all possible values for the amount of time it takes Sammy Speedster to drive from Houston to San Antonio. Since he is driving on a daily basis, the domain could be considered a continuous range from zero to some maximum value, perhaps 10 hours.

It's possible that Sammy could complete the trip in less than 3 hours if he were driving at a very high speed, but this would not be a common occurrence. Therefore, a reasonable domain could be considered to be between 3 and 10 hours.

The range, on the other hand, would be the set of all possible distances that Sammy could drive in the allotted time. Since we know that the distance is a constant 200 miles, the range would simply be 200 miles. It's possible that Sammy could drive more than 200 miles in a day if he were assigned additional routes, but this would not be relevant to this scenario.

In summary, a reasonable domain for Sammy's logbook would be between 3 and 10 hours, and the range would be a constant 200 miles.

A piecewise defined function is a function that is defined by different formulas on different intervals or "pieces" of its domain. This means that the formula used to calculate the output (the function value) of the function depends on the value of the input (the independent variable).

For this particular question, let C be the cost of fencing a backyard and let x be the length of the fence in feet. Then, we can write the piecewise defined function as:

C(x) =  30x, if 0 < x ≤ 300 OR

C(x) = 30(300) + 25(x - 300), if x > 300

In other words, if the length of the fence is less than or equal to 300 feet, the cost is simply 30 times the length of the fence. If the length of the fence is greater than 300 feet, the cost is the cost of the first 300 feet (30 times 300), plus 25 times the additional length of the fence beyond 300 feet.

Position vector = 3 ti + tj + 1/4t^2k
Time = 2
Find the velocity vector, speed, and acceleration vector of the object.

Answers

the velocity vector of the object is v(2) = 3i + j + k, the speed is sqrt(11), and the acceleration vector is a(t) = (1/2)k.

We're given the position vector and time and asked to find the velocity vector, speed, and acceleration vector of the object. Let's solve this step-by-step.

1. Differentiate the position vector with respect to time (t) to find the velocity vector:
Position vector: r(t) = 3ti + tj + (1/4)t^2k

Velocity vector: v(t) = dr(t)/dt = d(3ti)/dt + d(tj)/dt + d((1/4)t^2k)/dt

v(t) = 3di/dt + dj/dt + (1/2)tk

v(t) = 3i + j + (1/2)tk

2. Plug in the given time (t = 2) into the velocity vector to find the velocity at that time:
v(2) = 3i + j + (1/2)(2)k

v(2) = 3i + j + k

3. Find the speed by calculating the magnitude of the velocity vector:
Speed = |v(2)| = sqrt((3^2) + (1^2) + (1^2))

Speed = sqrt(9 + 1 + 1)

Speed = sqrt(11)

4. Differentiate the velocity vector with respect to time (t) to find the acceleration vector:
Acceleration vector: a(t) = dv(t)/dt = d(3i)/dt + d(j)/dt + d((1/2)tk)/dt

a(t) = 0i + 0j + (1/2)k

So, the velocity vector of the object is v(2) = 3i + j + k, the speed is sqrt(11), and the acceleration vector is a(t) = (1/2)k.

Lin's smart phone was fully charged when she started school at 8:00 a. M. At 9:20 a. M. , it was 90%


charged, and at noon, it was 72% charged.


1. When do you think her battery will die?


2. Is battery life a function of time? If yes, is it a linear function? Explain your reasoning.

Answers

1. It's impossible to determine exactly when Lin's battery will die without more information on her phone's battery capacity and usage patterns. However, we can estimate that it will likely die sometime after noon if the rate of battery drain remains constant.

2. Yes, battery life is a function of time. The longer a battery is in use, the more its charge will deplete. However, it is not necessarily a linear function as the rate of battery drain can vary depending on factors such as usage patterns, app activity, and temperature. In this specific case, it appears that the rate of battery drain may be slowing down as the percentage decrease from 90% to noon is less than the decrease from fully charged to 90%.

In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. For distinguishing such a linear function from the other concept, the term affine function is often used. A linear function from the real numbers to the real numbers is a function whose graph (in Cartesian coordinates) is a non-vertical line in the plane. The characteristic property of linear functions is that when the input variable is changed, the change in the output is proportional to the change in the input.

Linear functions are related to linear equations.

Answers

The critical value for a right-tailed test of a population mean at α=0.10 level of significance with 20 degrees of freedom is 1.325.

The critical value for a left-tailed test of a population mean at the α=0.10 level of significance based on a sample size of n=15 is -1.345.

The critical value(s) for a two-tailed test of a population mean at the α=0.01 level of significance based on a sample size of n=11 is -2.718 and 2.718.

To find the critical values, we need to use a t-distribution table or a statistical software that provides the critical t-values for a specific level of significance and degrees of freedom.

For part (a), since it's a right-tailed test, the critical value will be positive, and we need to look for the t-value that corresponds to an area of 0.10 to the right of the mean in the t-distribution table. With 20 degrees of freedom, the critical value is 1.325.

For part (b), since it's a left-tailed test, the critical value will be negative, and we need to look for the t-value that corresponds to an area of 0.10 to the left of the mean in the t-distribution table. With 15 degrees of freedom, the critical value is -1.345.

For part (c), since it's a two-tailed test, we need to split the significance level equally between the two tails. We need to find the t-values that correspond to an area of 0.005 to the left of the mean and 0.005 to the right of the mean in the t-distribution table. With 11 degrees of freedom, the critical values are -2.718 and 2.718.

The carpet for the office you completed cost $576. If you're using the same carpet in the new client's bedroom, how much will it cost? Round up to the nearest whole dollar. (Hint: You may want to find the area of each room and the cost of the carpet per square foot. )

Answers

The cost of a similar carpet in the client's bedroom is $225 when the area of the bedroom is 120  square feet.

Given Data:

Cost of Carpet = $576

length of office room =  16

Width of office room = 19.2

length of Bedroom = 12

Width of Bedroom = 10

We need to determine the area of the office and the bedroom. we can determine it by using the Area of a rectangle formula which is given as,

Area of a rectangle = length × width

Area of Office  = length  of office room × width of office room

= 16 × 19.2

= 307.2 square feet

Area of Bedroom = length of Bedroom × width of Bedroom

= 12 × 10

= 120  square feet

Therefore, the area of the office is 307.2 square feet, and the area of the Bedroom is 120  square feet.

From the above data, the area of the office is 307.2 square feet and the carpet will cost $576 for the office. we need to find the cost of the carpet for the 120 square feet bedroom, let's assume the cost as x, and cross multiply we get,

x = 120 × 576 / 307.2

x = 69120 / 307.2

x = $225

Therefore, the cost of the bedroom carpet is $225.
