What's the slope of the table

Answer:

A = 1/2b^2 + 3b

Step-by-step explanation:

If the height of the triangle is 6 units longer than the base length, we can represent the height with the variable h and the base length with the variable b.

h = b + 6

We can substitute h with b+6 in the formula for the area of the triangle:

A = 1/2bh

A = 1/2b(b+6)

So, the area of the triangle can be represented in terms of b only, as

A = 1/2b^2 + 3b

The polynomial expression would be 30G + 15S.

What is the polynomial expression?

A polynomial expression is an algebraic expression that is made up of one or more terms, where each term is the product of a constant coefficient and one or more variables raised to a non-negative integer power.

Elizabeth earns a $30 bonus for each gold membership she sells, and a $15 bonus for each silver membership she sells. Let G be the number of gold memberships she sells and S be the number of silver memberships she sells.

We can express Elizabeth's total bonus as:

$30G + $15S

This is a polynomial expression because it is a sum of two or more terms, each term being the product of a constant coefficient and a non-negative power of a variable.

It is also a linear polynomial expression because the highest power of the variable is 1.

Hence, the polynomial expression would be 30G + 15S.

A scale factor of 1/3 is not an enlargement. A scale factor of less than 1 is considered a reduction and not an enlargement.

An enlargement is a transformation that increases the size of a figure, it is characterized by a scale factor greater than 1. A dilation with a scale factor greater than 1 will increase the size of a figure and thus is considered an enlargement.

A dilation with a scale factor of 1/3 will decrease the size of a figure, as each point on the figure will be moved one-third as far from the origin as it was before the dilation. This means that the dilated figure will be smaller than the original figure and will have a scale factor of 1/3.

It's important to note that if the scale factor is less than 1, the dilation will reduce the size of the figure and if the scale factor is greater than 1, the dilation will increase the size of the figure.

WY intersects UV at Y and hence the value of UV is 8.

They are referred to be intersecting lines when two or more lines in a plane cross each other. The point of intersection, which can be found on all intersecting lines, is the common point shared by the intersecting lines.

Given that WY intersects UV at Y.

Hence, the value of UY = YV.

Substitute the value of UY and YV as follows:

UY = YV

3x- 6 = x + 2

3x - x = 2 + 6

2x = 8

x= 2

Now, the value of UV = UY + YV

Substitute the values:

UV = UY + YV

UV = 3x - 6 + x + 2

UV = 4x - 4

Substitute the value of x as follows:

UV = (4)(2) - 4

UV =8 -4

UV = 4

Hence, the value of UV is 8.

Company A charges $5.00 and 6 cents much more for x miles than Company B. The solution is obtained using arithmetic operations.

There are four basic operations which are listed as follows: Addition(‘+’): This operation deals with finding the sum. Subtraction(‘-’): This operation deals with finding the difference.   Multiplication(‘×’): This operation deals with finding the product. Division(‘÷’): This operation deals with finding the quotient.

In order to find how much more does company A charge than company B, we need to subtract the charges of company B from that of Company A.

So, on subtracting we get,

$55.50 and 15 cents - $50.50 and 9 cents = $5.00 and 6 cents per mile.

For x miles, we multiply $5.00 and 6 cents by x miles.

Also, we could convert dollars to cents by multiplying it by 100.

as $1 =100 cents.

5565 - 5059 cents = 506 cents.

For x miles, 506x cents.

Hence, Company A charges $5.00 and 6 cents much more for x miles than Company B.

Therefore , the solution of the given problem of linear equation comes out to be x = 4 and y =4.

A model of linear regression is one that applies the formula y=mx+b. B is the slope, and m is the y-intercept. Ignoring the fact that while both y and y are distinct components, the previous sentence is frequently referred as a "mathematical formula with two variables." Bivariate linear equations only have two variables. The application domains of linear equations have zero solutions in all cases. The equation for a single system of equations is Y=mx+b, where m stands for the gradient & b for the y-intercept. Y=mx+b, where m stands for slopes and b for the y-intercept, is how the equation is expressed.

Here,

Given :

=>  y = 2x -4

=> x + 2y = 12

and

=> x + 2(2x -4) = 12

=>  x + 4x - 8  =12

=>  5x = 20

=> x = 4

=> y = 2(4) - 4

=>  y = 8 -4

=> y =4

Therefore , the solution of the given problem of equation comes out to be x = 4 and y =4.

d) BF = 6

Considering that G is the incenter of triangle ABC, we have that

Using the right triangle CDG and applying Pythagoras theorem given by  the formula

hypotenuse² = opposite² + adjacent²

plugging the values as in the problem

GC² = GD² + DC²

37² = GD² + 35²

GD² = 37² - 35²

GD² = 144

take square root of both sides

GD = √144

GD = 12

Using the right triangle BEG to solve for BG

BG² = EB² + GE²

BG² = 6² + 12²

BG² = 180

take square root of both sides

BG = √180

BG = 13.42

Using the right triangle CFG to solve for FC

GC² = GF² + FC²

rearranging the equation

FC² = GC² - GF²

FC² = 37² - 12²

FC² = 1225

take square root of both sides

FC = √1225

FC = 35

Using the right triangle BFG to solve for BF

Answer:

The height of the cylinder is 10 cm.

Step-by-step explanation:

1. The volume of a cylinder is given by

-V = pi r^2 h  where r is the radius and h is the height

- 90 pi = pi r^2 h

2. We know the radius is 3

-90 pi = pi (3)^2 h

-90 pi = 9 pi h

3. Divide each side by 9 pi

- 90 pi /9 pi = 9 pi h / 9pi

- 10 =h

The height of the cylinder is 10 cm.

Based on the side-side-side rule, it is possible to construct the triangle.

Let the side a be 2.5 cm, side b be 3.0 cm and side c be 6.5 cm. Now, the sum of any two sides of triangle should be greater than the thrid side of triangle.

Side a + side b > side c

2.5 + 3 > 6.5

Performing addition on Left Hand Side of the equation

5.5 not greater than 6.5

Side b + side c > side a

3 + 6.5 > 2.5

Performing addition on Left Hand Side of the equation

9.5 > 2.5

side c + side a > side b

6.5 + 2.5 > 3

Performing addition on Left Hand Side of the equation

9 > 3

Thus, the right angled triangle can be constructed from sides 2.5 cm 3.0 cm and 6.5 cm.

An equation for the cost of the cheaper brand is y = 60x + 1,800.

An equation for the cost of the more expensive brand is y = 50x + 2,600.

The cost of running the cheaper unit for 36 months is $3,960.

The number of months for which the cost of both brands would be equal is 8 months.

In order to write an equation that model this situation, we would assign variables to the time and cost respectively, and then translate the word problem into algebraic equation as follows:

Since a brand cost $1800 to buy with a monthly operation fee of $60, an equation for the cost of this cheaper brand is given by:

y = 60x + 1,800.

When x = 36 months, the cost of running the cheaper unit is given by:

y = 60(36) + 1,800.

y = $3,960.

For the more expensive brand, we have:

y = 50x + 2,600.

Next, we would determine the number of months for which the cost of both brands would be equal;

50x + 2,600 = 60x + 1,800

60x - 50x = 2,600 - 1,800

It will cost Aurelia $631.80 to have her new computer shipped.

To calculate the shipping cost, we need to multiply the purchase price of the computer by the percentage of shipping cost, which is 8%.

To do this, we can use the following formula:

Shipping cost = Purchase price x (Shipping percentage/100)

In this case, the purchase price is $585 and the shipping percentage is 8, so we can plug in these values into the formula:

Shipping cost = $585 x (8/100)

Now we can solve the shipping cost:

Shipping cost = $46.80

So the total cost for Aurelia to have her new computer shipped would be

$585 + $46.80 = $631.80.

Thus, it will cost $631.80 for Aurelia to have her new computer shipped.
