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: 7 years old

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

2y+3=17     Rearrange variables

2y=14

y=7             David's age, y, is 7.

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.

Answer:

Suppose the original function is denoted by f(x). To represent the new function that is vertically stretched by a factor of 4 and then translated 3 units to the right, we can use the following equation:

g(x) = 4 f(x - 3)

In this equation, f(x - 3) represents the original function f(x) translated 3 units to the right, and the multiplication by 4 stretches the function vertically by a factor of 4. Therefore, g(x) represents the new function that is vertically stretched by a factor of 4 and then translated 3 units to the right.

Step-by-step explanation:

Using inequalities, Y(x=0) = -2 and X(y=0) = -2 in region 1.

To pick area 1, draw a line at the intersection of (-2,0) and (0, -2), then choose the right side. such as.

Region 2) To pick the region to the left or upwards in region 2, we must draw a line from (0,2) to (-2,4).

Y(x=0) = 2\sX(y=-2) = -4

Region 3) To pick the region to the right, we must draw a line connecting (-4,0) and (0,4), as I'll demonstrate.

Inequalities in mathematics describe the relationship between two non-equal numbers. Equal does not necessarily mean unequal. 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

The minimum is thus found at (x,y) = (-5/4, -3/4)

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

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°

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

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:

Given,

 The amount of rice the restaurant had when they opened = 13 lbs

The amount of rice that was cooked and served = 3 1/12lbs

We are asked to find the amount of rice left.

This can be found by subtracting the amount of rice served from the total amount of rice.

Note that the amount of rice served is in fractions.

So we use fraction subtraction to solve this.

Then,

amount of rice left = 13 - 3 1/12

3 1/12 is a mixed fraction.

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).

What is Fraction ?

A fraction is a number that represents a part of a whole or a ratio between two quantities. It is expressed as a ratio of two integers, with the numerator (top number) representing the part or quantity being considered and the denominator (bottom number) representing the total or whole.

To convert a fraction of a full rotation to degrees, we can use the fact that a full rotation is equivalent to 360 degrees.

In this case, 5/18 represents a fraction of the full rotation, where the numerator (5) represents the number of counter-clockwise rotations and the denominator (18) represents the total number of rotations in a full circle.

To find the number of degrees, we can multiply the fraction by 360 degrees:
