The charge for the third company for the 8 feet of copper pipe as required to be determined is; $8.50.

As evident from the task content;

For the first company; Pipe for $1.50 per foot and a rebate offering $2.00 off the total.

Therefore, total charge is; 8(1.50) - 2 = $10.

For the second company; Pipe for $1.75 per foot and a coupon offering $0.25 off each foot.

Therefore, total charge is 8(1.75) - 8(0.25) = $12.

Hence, since the better deal is; $10.

Ultimately, the charge of the third company whose offer is; $1.50 less than the charge of the better deal is; 10 - 1.50 = $8.50.

If you are considering taking out a loan against the value of your home equity, there are several options to consider. One of the most common types of home loans for this purpose is a home equity loan or a home equity line of credit (HELOC).

The difference between the value of your home and the amount you owe on your mortgage is known as Home equity.

A home equity loan is a lump sum loan that allows you to borrow against the equity in your home. You receive the funds in one lump sum and then make fixed monthly payments over a set period of time, typically 5-15 years.

The interest rate on a home equity loan is generally fixed, which means that your monthly payments will remain the same throughout the life of the loan.

With a HELOC, you have access to a revolving line of credit, much like a credit card, and you only pay interest on the amount you borrow. The interest rate on a HELOC is typically variable, which means that your monthly payments may fluctuate over time.

Both home equity loans and HELOCs may make sense for helping your sister through a rough patch, as they can provide you with access to cash quickly and may offer lower interest rates than other types of loans. However, it's important to remember that both of these loans are secured by your home, which means that if you are unable to make your payments, you risk losing your home.

Answer:150 times

Step-by-step explanation:

The average professional basketball player's salary is 6x10^6 dollars yearly, while the average American worker's salary is 4x10^4 dollars yearly.

To find how many times greater the average professional basketball player's salary is, we can divide the basketball player's salary by the worker's salary:

6x10^6 / 4x10^4 = (6/4)x10^(6-4) = 1.5x10^2 = 150

Therefore, the average professional basketball player's salary is 150 times greater than the average American worker's salary.

Step-by-step explanation:

To rewrite the equation x² + 18x + 7 = 4 in the form (x - p)² = q, we need to complete the square by adding and subtracting a constant term.

First, we subtract 4 from both sides of the equation:

x² + 18x + 7 - 4 = 0

Simplifying, we get:

x² + 18x + 3 = 0

To complete the square, we need to add and subtract the square of half the coefficient of x, which is (18/2)^2 = 81:

x² + 18x + 81 - 81 + 3 = 0

Simplifying, we get:

(x + 9)² - 78 = 0

Now, we can rewrite the equation in the desired form by adding 78 to both sides:

(x + 9)² = 78

Therefore, the values to be entered in the boxes are:

1: (x + 9)

Answer:

Step-by-step explanation: The equation should be

A = 35 - 4t

B = 50 - 7t

And, the Height = 15 inches

Calculation of the equation and height;

Since

Height of snowman A = 35 inches

Height of snowman B = 50 inches

Height decrease of snowman A = 4 inches per hour

Height decrease of snowman B = 7 inches per hour

Here, t = number of hours

So, the equation should be

A = 35 - 4t      

B = 50 - 7t      

Now for the same height

35 - 4t = 50 - 7t

-4t + 7t = 50 - 35

3t = 15

t = 15

So,

A = 35 - 4(5) = 35 - 20 = 15 inches

B = 50 - 7(5) = 50 - 35 = 15 inches

As a result, x = pi/6 is the only answer in the range [0,2pi).

When quantifying the angles of trigonometry or periodic functions, radians are frequently taken into account. Radians are always expressed in units of pi, with pi equivalent to either 3.14 or 22/7.

We can start by simplifying the left-hand side of the equation using the identity:

csc x = 1/sin x

4 sec x csc x = 4(1/cos x)(1/sin x) = 4/(cos x sin x)

Substituting this back into the original equation, we get:

4/(cos x sin x) = 8 csc x

Multiplying both sides by cos x sin x, we get:

4 = 8 sin x

Dividing both sides by 8, we get:

sin x = 1/2

This means that x is either pi/6 or 5pi/6, since these are the two angles in the interval [0,2pi) where sin x = 1/2.

However, we need to check if these solutions satisfy the original equation.

For x = pi/6:

4 sec x csc x = 4 sec(pi/6) csc(pi/6) = 4(2) (2/√3) = 16/√3

8 csc x = 8 csc(pi/6) = 8(2/√3) = 16/√3

So, x = pi/6 is a solution.

For x = 5pi/6:

4 sec x csc x = 4 sec(5pi/6) csc(5pi/6) = 4(-2) (-2/√3) = 16/√3

8 csc x = 8 csc(5pi/6) = 8(-2/√3) = -16/√3

So, x = 5pi/6 is not a solution.

Therefore, the only solution in the interval [0,2pi) is x = pi/6.

To determine whether the function f(x) = (x^2-2x-3)/(x^2+3x+2) has any holes, we can factor the numerator and denominator and simplify the expression. The numerator can be factored as:

x^2 - 2x - 3 = (x - 3)(x + 1)

And the denominator can be factored as:

x^2 + 3x + 2 = (x + 1)(x + 2)

Therefore, we can simplify the function as:

f(x) = [(x - 3)(x + 1)]/[(x + 1)(x + 2)]

The factor of (x + 1) appears in both the numerator and denominator, so we can simplify further by canceling it out:

f(x) = (x - 3)/(x + 2)

Since (x + 1) was canceled out, we have a hole in the graph of the original function at x = -1. To find the coordinates of the hole, we can evaluate the simplified function at x = -1:

f(-1) = (-1 - 3)/(-1 + 2) = -4

Therefore, the hole in the graph of the original function is located at the point (-1, -4).

Step-by-step explanation:

To find the maximum height of the object, we need to determine the vertex of the parabolic function f(t) = 16t^2 + 16t + 7.

The vertex of a parabola in the form f(t) = at^2 + bt + c is given by (-b/2a, f(-b/2a)). In this case, a = 16, b = 16, and c = 7, so the vertex is:

(-b/2a, f(-b/2a)) = (-16/(216), f(-16/(216))) = (-1/2, f(-1/2))

To find f(-1/2), we can substitute t = -1/2 into the function:

f(-1/2) = 16(-1/2)^2 + 16(-1/2) + 7 = 8 - 8 + 7 = 7

Therefore, the vertex is at (-1/2, 7). This means that the maximum height of the object is 7 feet above the ground.

Alternatively, we could also use the fact that the maximum height occurs at the vertex of the parabola, which is the point where the derivative of the function is zero. The derivative of f(t) is:

f'(t) = 32t + 16

Setting this equal to zero and solving for t, we get:

32t + 16 = 0

t = -1/2

So the maximum height occurs at t = -1/2, which corresponds to the vertex of the parabola, and the maximum height is 7 feet.

Angles a and b are each measured at 97°, while angles c and d are each measured at 68°. Angles and lines were used to arrive at the solution.

Straight lines have careless depth and careless width. Other types of lines include those that are perpendicular, transverse, and intersecting other lines. A form is considered to have an angle if two of its rays originate from the same location.

We are given two parallel lines so,

Angle a = 97°   (Corresponding angles)

We know that angles on a straight line form a linear pair.

So,

⇒112° + d = 180°

⇒d = 68°

Angle c = 68°     (Alternate interior angles)

Using angle sum property,

⇒ a + b + 68° = 180°

Answer:

The triangle is acute.

Step-by-step explanation:

To determine whether the side lengths of 3, 7, and 9 can form a triangle, we need to apply the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let's check if this condition is satisfied for the given side lengths:

3 + 7 = 10 > 9, so the sum of the two smaller sides is greater than the largest side.

7 + 9 = 16 > 3, so the sum of the two smaller sides is greater than the largest side.

3 + 9 = 12 > 7, so the sum of the two smaller sides is greater than the largest side.

Since all three inequalities are true, we can conclude that the given side lengths of 3, 7, and 9 can form a triangle.

To determine whether the triangle is acute, right, or obtuse, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Let's first determine which side is the longest. Since 9 is the largest side length, it must be the hypotenuse if the triangle is right-angled.

However, using the Pythagorean theorem, we can see that:

3^2 + 7^2 = 58 < 9^2, so the triangle is not right-angled.

Therefore, the triangle must be either acute or obtuse. To determine which one, we can use the law of cosines, which states that in any triangle:

c^2 = a^2 + b^2 - 2ab*cos(C)

where a, b, and c are the side lengths, and C is the angle opposite to side c.

Let's apply this formula to the triangle with side lengths 3, 7, and 9:

9^2 = 3^2 + 7^2 - 2(3)(7)*cos(C)

81 = 58 - 42*cos(C)

cos(C) = (58 - 81)/(-42) = 0.5476

C = cos^(-1)(0.5476) = 56.69 degrees

Therefore, the largest angle in the triangle is approximately 56.69 degrees. Since this angle is less than 90 degrees, we can conclude that the triangle is acute.

Answer:

obtuse angled triangle

Step-by-step explanation:

for the sides to form a triangle

the sum of any 2 sides must be greater than the third side.

3 + 7 = 10 > 9

3 + 9 = 12 > 7

7 + 9 = 16 > 3

then the 3 sides 3 , 7 , 9 will form a triangle

given 3 sides a , b , c with c the longest side

• if a² + b² = c² ⇒ right triangle

• if a² + b² > c² ⇒ acute angled triangle

• if a² + b² < c² ⇒ obtuse angled triangle

here a = 3 , b = 7 , c = 9

a² + b² = 3² + 7² = 9 + 49 = 58

c² = 9² = 81

since a² + b² < c²

then triangle is obtuse

Step-by-step explanation: The two quickest ways to solve these types of problems are by guess and check, and systems of equations. I will show you how to solve this problem with systems of equations since it is a systematic method.

We can replace the ages of Ethan and David with variables. Ethan's age is x and David's is y. Ethan is 3 years older than David and this can be represented by: y+3=x since 3 will have to be added to David's age, y to get Ethan's age, x. A second equation we can make is x+y=17 since the sum of their two ages is 17. Now we solve the system by first isolating a variable and then plugging that into the second equation.

y+3=x         x is already isolated for us

x+y=17

(y+3)+y=17 We substitute x in the second equation for y+3

Using the equatiοn, we can find the sοlutiοn fοr cοs(b) in terms οf sin(b):

cοs(2b) = (1 - sin(2b)) (b)

Inputting this intο the fοrmula fοr tan(b), we οbtain:

When two values are not equal, we typically use the "not equal symbol ()". However, several inequalities are utilised to compare the numbers, whether it is less than or higher than.

The feasible area is now visible. Let's determine the vertices' coordinates.

Where the blue and green lines intersect is our first vertex.

3x + 2 = x + 4 and y = 3x + 2

3x - x = 4 - 2

y = 3× (1) + 2 = 3 + 2 = 5 when 2x = 2x = 1

(X, Y) = Vertex 1 (1,5)

The intersection of the red and green lines is at vertex #2:

y = -x -2; y = x + 4; y = x + 4 = -x - 2; and y = x + x = -2 - 4

2x = -6, x = -6/2, and y = (-3) + 4 = -3 + 4 = 1 are the results.

(X, Y) = Vertex 2 (-3,1)

The intersection of the red and blue lines is at vertex 3:

y = -x - 2, y = 3x + 2 -x - 2, and y = 2 + 2 -4 x = 4 x = -4 / 4 = -1;

So, y = 3×(-1) + 2 = -3 + 2 = -1

(X, Y) = Vertex 3 (-1, -1)

Let's now modify the graph by including the supplied equation.

The intercept where Y=0 is 0 is given by f(x,y) = -3x + 5y = 0 5y = 3x + 0 y = 3/5 × X + 0

the gradient m = 3/5

A line can be drawn from (0,0) to (-10, -6)

Let's now examine how it would appear in the area where it is practical.

We can see that the function intercepts the blue line or the line of the second section, which is where the largest value is located.

y = 3x + 2 3x + 2 (3/5 - 3) x = 2 -12/5 × x = 2 x = -5/6.

Hence, y = 3x + 2 3/5 × (-5/6) = -1/2.

The maximum is therefore found at (x,y) = (-5/6, -1/2).

The point where the function crosses the red line now marks the minimum.

y = 3/5 × x; y = -x -2

3/5 x = -x - 2\s (3/5 + 1) × x = -2\s8/5 x = - 2\sx = -2× (5/8) = -5/4.

y = 3/5 × (-5/4) = -3/4

Therefore, the estimated mean is roughly 0.154, but without more data, we are unable to calculate the SEM or group size.

The total of all values divided by all of the values constitutes the result of a set, also called as the arithmetic mean. It is considered to be the most popular central trend indicator, and the word "mean" is commonly used to describe it. multiply the total amount of numbers in the library by the overall amount of values inside the gathering to get this result. Either original data or data that's been combined into frequency charts can be used for calculations. The average of a figure is known to as the average.

Here,

Given a normal distribution, the MAD and standard deviation (SD) are roughly inversely proportional to one another as follows:

=> MAD = 1.4826 × SD

As a result, we can calculate the standard deviation as follows:

=> SD = MAD / 1.4826

Since the MAD in this instance is provided as 3.2, we can calculate the standard deviation as follows:

=> SD ≈ 3.2 / 1.4826 ≈ 2.16

The standard error of the mean (SEM), which can be determined as follows, then provides the variability of the mean.

=> SEM ≈ SD / sqrt(n)

=> CV Equals SD/mean

To find the mean, we can change this equation as follows:

a) Mean Equals SD / CV

With the estimated numbers for SD and CV substituted, we obtain:

=> mean ≈ 2.16 / 14 ≈ 0.154

Therefore, the estimated mean is roughly 0.154, but without more data, we are unable to calculate the SEM or group size.
