Complete the following to use the difference of two squares to find the product of 22 and 18.( + )( - ) =( )2 - ( )2 =396

Answers

The complete equation of two squares to find the product of 22 and 18 is (22 + 18)(22 - 18) = 396

When we can interpret an expression as the difference of two perfect squares, i.e. a2-b2, we can factor it as (a+b)(a-b).

To use the difference of two squares to find the product of 22 and 18:

First, find the average of the two numbers:

(22 + 18) ÷ 2 = 20

Then, find the difference between the two numbers:

22 - 18 = 4

Now we can write:

(20 + 4)(20 - 4) = 24 × 16 = 384

But we need to add the extra 12 to get 396:

(20 + 4)(20 - 4) + 12 = 396

So the completed equation is:

(22 + 18)(22 - 18) = 396

The minimum value of a - b is around 2.2 with a = 8.4 rounded to one decimal place and b = 6.19 rounded to two decimal places.

We must first subtract b (lower bound) from a (upper bound) to determine the least value of a - b, which is equal to 8.4 - 6.19 = 2.21. 2.21 is the difference between a and b. However, the question requests that we round off this number to the nearest tenth.

Identify all the lines on the graph with unit rates that are less than 2 and greater than the unit rate of the relationship in the table. X y

7 8

14 16

21 24

Answers

The only line on the graph with a unit rate less than 2 is the horizontal line passing through y=8.

To identify the unit rates on the graph, we need to find the slope of the line connecting each pair of points. We can use the formula:

slope = (change in y) / (change in x)

For example, the slope between the first two points (7,8) and (14,16) is:

slope = (16-8) / (14-7) = 8/7

Similarly, we can find the slopes for the other pairs of points:

- between (7,8) and (21,24): slope = (24-8) / (21-7) = 16/14 = 8/7
- between (14,16) and (21,24): slope = (24-16) / (21-14) = 8/7

Notice that all three slopes are equal, which means the graph represents a line with a constant unit rate of 8/7.

To find lines with unit rates less than 2, we need to look for steeper lines on the graph. Any line with a slope greater than 2/8 (or 1/4) will have a unit rate greater than 2.

One way to see this is to note that a slope of 2/8 means that for every 2 units of increase in y, there is 8 units of increase in x. This is equivalent to saying that the unit rate is 2/8 = 1/4. If the slope is greater than 2/8, then the unit rate is greater than 1/4, and therefore greater than 2.

Looking at the graph, we can see that the steepest line has a slope of 2/3, which means it has a unit rate of 2/3. Therefore, any line with a slope greater than 2/3 will have a unit rate greater than 2, and any line with a slope less than 2/3 will have a unit rate less than 2.

To summarize:

- The graph represents a line with a constant unit rate of 8/7.
- Any line with a slope greater than 2/3 has a unit rate greater than 2.
- Any line with a slope less than 2/3 has a unit rate less than 2.

Evaluate the integral ∫8(1-tan²(x)/sec² dx Note Use an upper-case "C" for the constant of integration

Answers

The integral ∫8(1-tan²(x)/sec² dx Note Use an upper-case "C" for the constant of integration is ∫8(1-tan²(x)/sec²(x)) dx = 8 tan(x) + C where C is the constant of integration.

To evaluate the integral ∫8(1-tan²(x)/sec²(x)) dx, we need to use trigonometric identities to simplify the integrand.

First, we use the identity tan²(x) + 1 = sec²(x) to rewrite the integrand as follows:

8(1 - tan²(x)/sec²(x)) = 8(sec²(x)/sec²(x) - tan²(x)/sec²(x))

Simplifying this expression by canceling out the common factor of sec²(x), we get:

8(sec²(x) - tan²(x))/sec²(x)

Next, we use the identity sec²(x) = 1 + tan²(x) to simplify the expression further:

8(sec²(x) - tan²(x))/sec²(x) = 8((1 + tan²(x)) - tan²(x))/sec²(x)

Simplifying the expression inside the parentheses, we obtain:

8/ sec²(x)

Therefore, the integral simplifies to:

∫8(1-tan²(x)/sec²(x)) dx = ∫8/ sec²(x) dx

We can now use the substitution u = cos(x) and du/dx = -sin(x) dx to transform the integral into a simpler form:

∫8/ sec²(x) dx = ∫8/cos²(x) dx = 8∫cos(x)² dx

Using the power-reducing formula cos²(x) = (1 + cos(2x))/2, we get:

8∫cos(x)² dx = 8/2 ∫(1 + cos(2x))/2 dx = 4(x + 1/2 sin(2x)) + C

Substituting back u = cos(x), we obtain:

∫8(1-tan²(x)/sec²(x)) dx = 8 tan(x) + C

where C is the constant of integration.

When dealing with absolute value expressions, we must consider both the positive and negative values of the argument.

In this case, we are asked to simplify[tex]|x÷3| if x<0[/tex], which means that x is a negative number.

To simplify this expression, we must first evaluate x÷3, which gives us a negative number divided by a positive number, resulting in a negative quotient.

However, since we are only interested in the absolute value of this quotient, we must ignore the negative sign and write the expression as:

[tex]|x÷3| = -(x÷3)[/tex]

Consider the function F(x,y)= e - x2 16-y2 76 and the point P(2.2) a. Find the unit vectors that give the direction of steepest ascent and steepest descent at P. b. Find a vector that points in a direction of no change in the function at P.

Answers

At the point P(2,2), the unit vector for the direction of steepest ascent is  (-i + j)/√2, and the unit vector for the direction of steepest descent is (i - j)/√2. A vector that points in the direction of no change in the function at P is (2e^(-1/3)/49) i + (2e^(-1/3)/49) j + (2/7) k.

To find the unit vectors that give the direction of steepest ascent and steepest descent at P, we need to find the gradient of F at P and normalize it to obtain a unit vector.

First, we find the partial derivatives of F with respect to x and y

Fx = -2x e^(-x^2/(16-y^2))/((16-y^2)^2)

Fy = 2y e^(-x^2/(16-y^2))/((16-y^2)^2)

Plugging in the coordinates of P, we get

Fx(2,2) = -2e^(-1/3)/49

Fy(2,2) = 2e^(-1/3)/49

Therefore, the gradient of F at P is

∇F(2,2) = (-2e^(-1/3)/49) i + (2e^(-1/3)/49) j

To obtain the unit vector in the direction of steepest ascent, we normalize the gradient

u = (∇F(2,2))/||∇F(2,2)|| = (-i + j)/√2

To obtain the unit vector in the direction of steepest descent, we take the negative of u

v = -u = (i - j)/√2

To find a vector that points in a direction of no change in the function at P, we need to find a vector orthogonal to the gradient of F at P. One way to do this is to take the cross product of the gradient with the vector k in the z-direction

w = ∇F(2,2) x k = (2e^(-1/3)/49) i + (2e^(-1/3)/49) j + (2/7) k

Therefore, the vector that points in a direction of no change in the function at P is

(2e^(-1/3)/49) i + (2e^(-1/3)/49) j + (2/7) k

Answers

C(12) represents the total cost (in dollars) of renting the industrial cleaning unit for 12 hours.

How to find the representation of function?

The problem gives us a function C(t) = 60 + 24t, where t represents the number of hours that an industrial cleaning unit is rented for. The function tells us that the total cost (in dollars) of renting the unit is equal to $60 plus $24 per hour.

Now, we are asked to find what C(12) represents. To do so, we substitute t = 12 into the function, which gives us:

C(12) = 60 + 24(12)

We can simplify this expression by multiplying 24 by 12, which gives us:

C(12) = 60 + 288

Adding 60 and 288 together, we get:

C(12) = 348

So, C(12) represents the total cost (in dollars) of renting the industrial cleaning unit for 12 hours. Therefore, the correct answer to the question is: The cost of renting the unit for 12 hours.

Annette drives her car 115 miles and has an average of a certain speed. If the average speed had been 8mph more, she could have traveled 138 miles in the same length of time. What was her average speed?

Answers

Annette's average speed was 40 mph if Annette drives her car 115 miles and has an average of a certain speed.

What is Average speed ?

Average speed is the total distance traveled divided by the total time taken to travel that distance. It is a measure of the overall speed of an object or person over a certain period of time.

Let's call Annette's original average speed "x". We can use the formula:

distance = speed x time

to set up two equations based on the given information.

For the first part of the trip:

115 = x * t1 (where t1 is the time it took Annette to travel 115 miles at speed x)

For the second part of the trip:

138 = (x + 8) * t2 (where t2 is the time it would have taken Annette to travel 138 miles at a speed of x + 8)

Since Annette traveled the same amount of time for both parts of the trip, we can set t1 equal to t2:

t1 = t2

We can solve for t1 in the first equation:

t1 = 115 : x

And we can solve for t2 in the second equation:

t2 = 138 : (x + 8)

Since t1 = t2, we can set the two expressions for t equal to each other:

115 : x = 138 : (x + 8)

Now we can solve for x:

115(x + 8) = 138x

115x + 920 = 138x

920 = 23x

x = 40

Therefore, Annette's average speed was 40 mph.

Answers

Lower Bound: 20 - 29.67 ≈ -9.67

How to solve

The conversion of MAD to the standard deviation for normal distributions can be obtained using the given relationship:

Standard Deviation (σ) = MAD / 0.6745

For both distributions, the MAD holds a value of $20, thus arriving at σ ≈ 29.67.

There are two normal distributions now defined by their parameters as follows:

Mean (µ1) = $100 and Standard Deviation (σ1) = 29.67

Mean (µ2) = $120 and Standard Deviation (σ2) = 29.67.

Since both distributions share an equivalent standard deviation, we can perform a comparison of means to determine the overlap between them.

Typically there is observed moderate overlapping within one standard deviation from the difference in means.

The calculation of the difference in means indicates µ2 - µ1 = 120 - 100 = 20. Taking one standard deviation (which equates to 29.67) into consideration with respect to the difference of the means leads us to this range:

Lower Bound: 20 - 29.67 ≈ -9.67

Upper Bound: 20 + 29.67 ≈ 49.67.

It's noteworthy that negative values would not make sense within this context leading us to assume that the approximate overlap range is situated between $0 and $50 resulting in these normal distributions manifesting a sensible amount of overlap therein.

a man in a plane is looking down at a building below. if the man is 40,000 feet away from the building and the altitude of the man is 33,000 feel what is the angle of depression from the man to the building below

Answers

The angle of depression from the man to the building below is approximately 39.81°.

To find the angle of depression from the man to the building below, we'll use the tangent function and the given information.

Given:
- The man is 40,000 feet away from the building horizontally.
- The man's altitude is 33,000 feet.

Step 1: Identify the opposite and adjacent sides in relation to the angle of depression.
- The opposite side is the altitude (33,000 feet).
- The adjacent side is the horizontal distance (40,000 feet).

Step 2: Use the tangent function to find the angle of depression.
tan(angle) = opposite/adjacent
tan(angle) = 33,000/40,000

Step 3: Find the inverse tangent of the ratio to get the angle.
angle = arctan(33,000/40,000)

Step 4: Calculate the angle.
angle ≈ 39.81°

The angle of depression from the man to the building below is approximately 39.81°.

if the silver sheet costs $9.75 per cm^2, the copper sheet costs $3.25 per cm^2, and the stone costs $1.75 per cm^2, what is the materials cost for the brooch

Answers

AnswerAnswer:

Step-by-step explanation:

To determine the materials cost for the brooch, we need to know the area of each material used in the brooch. Let's say that the brooch is made up of a 5 cm x 5 cm square of silver, a 2 cm x 2 cm square of copper, and a 3 cm x 1 cm rectangle of stone.

The area of the silver sheet is 5 cm x 5 cm = 25 cm^2, so the cost of the silver is 25 cm^2 x $9.75/cm^2 = $243.75.

The area of the copper sheet is 2 cm x 2 cm = 4 cm^2, so the cost of the copper is 4 cm^2 x $3.25/cm^2 = $13.

The area of the stone is 3 cm x 1 cm = 3 cm^2, so the cost of the stone is 3 cm^2 x $1.75/cm^2 = $5.25.

Therefore, the total materials cost for the brooch is $243.75 + $13 + $5.25 = $262.

Jose reads his book at an average rate of


2. 5


2. 5 pages every four minutes. If Jose continues to read at exactly the same rate what method could be used to determine how long it would take him to read


20


20 pages?

Answers

It would take Jose approximately 3232 minutes (or about 53.87 hours) to read 2020 pages at the same rate of 2.5 pages every four minutes.

To determine how long it would take Jose to read 2020  runners at the same rate of2.5  runners every four  twinkles, we can use a proportion.   Let x be the number of  twinkles it would take Jose to read 2020  runners. also, we can set up the following proportion:

2.5 pages / 4 minutes = 2020 pages / x minutes

To solve for x, we can cross-multiply and simplify:

2.5 pages * x minutes = 4 minutes * 2020 pages

2.5x = 8080

x = 8080 / 2.5

x = 3232

Therefore, it would take Jose approximately 3232 minutes  to read 2020 pages at the same rate of 2.5 pages every four minutes.

You decide to make and sell bracelets. The cost of your materials is $84.00. You charge $3.50 for each bracelet. Write a function that represents the profit p for selling b bracelets.

Answers

The function that represents the profit p for selling b bracelets is p = 3.5b - 84

Write a function that represents the profit p for selling b bracelets.

From the question, we have the following parameters that can be used in our computation:

The cost of your materials is $84.00. You charge $3.50 for each bracelet.

This means that

Cost of b brackets = 3.5b

So, we have

Profit = Cost of b brackets - Cost price

substitute the known values in the above equation, so, we have the following representation

p = 3.5b - 84

Hence, the function that represents the profit p for selling b bracelets is p = 3.5b - 84

There are 157 newly built homes in a subdivision 68 gallons of paint and 13 paint brushes were used for each house about how many gallons of paint we use for the new homes

Answers

About 10,676 gallons of paint were used to paint the 157 newly built homes in the subdivision, assuming each house required exactly 68 gallons of paint and 13 paint brushes.

How to solve this statement problem?

The statement problem states that there are 157 newly built homes in a subdivision, and that 68 gallons of paint and 13 paint brushes were used for each house. This means that each house required 68 gallons of paint and 13 paint brushes.

To find the total amount of paint used for all 157 houses, we need to multiply the amount of paint used per house (68 gallons) by the number of houses (157):

Total amount of paint = 68 gallons/house x 157 houses

Total amount of paint = 10,676 gallons

Therefore, approximately 10,676 gallons of paint were used for the 157 newly built homes in the subdivision.

It's worth noting that this calculation assumes that each house required exactly 68 gallons of paint and 13 paint brushes. In reality, there may be some variation in the amount of paint and brushes used for each house, so the actual total may be slightly different.

However, this calculation provides a reasonable estimate of the total amount of paint used

A can is to be made to hold a litre of oil. Find the radius of the can that will minimize the cost of the metal to make the can. (1L = 1000 cm)

Answers

The problem involves finding the radius of a cylindrical can that will minimize the cost of the metal to make the can, given that the can must hold one liter of oil.

Specifically, we need to find the radius of the can that will minimize the surface area, and hence the cost, of the metal required to make the can.

To solve the problem, we need to first write an expression for the surface area of the can in terms of its radius, and then differentiate this expression with respect to the radius to find the critical point. We then need to check that the critical point corresponds to a minimum value of the surface area, which will give us the optimal radius for the can. Optimization problems like this one are used in many fields, including engineering, economics, and physics, to find the best course of action given certain constraints and objectives.

Answers

The average number of vehicles registered in each borough of NYC is 4.2 x 10^5.

To find the average number of vehicles registered in each borough of NYC, we need to divide the total number of registered vehicles by the number of boroughs. Therefore, the average number of vehicles registered in each borough can be calculated as:

Average number of vehicles = Total number of vehicles registered / Number of boroughs

= 2.1 x 10^6 / 5

= 4.2 x 10^5

Therefore, the average number of vehicles registered in each borough of NYC is 4.2 x 10^5.
