The longest and shortest possible lengths of the third side of the triangle are 4.9 cm and 11.1 cm.

It states that the opposite side of a triangle is divided into segments by each angle bisector that are proportional in length to the adjacent sides.

Given:

An angle bisector divides the opposite side of the triangle into segments 6 cm and 4 cm long.

Second side of the triangle is 7.4 cm.

We have to calculate the longest and shortest possible lengths of the third side of the triangle.

By Angle Bisector Theorem we can solve this problem,

In the triangle ABC, AD is the angle that bisects angle A, placing D on side BC.

Now, BD / DC = AB / AC

BC = 6 + 4 = 10 cm

Angle bisector divides BC into 2 segments,

BD = 6 cm

CD = 4 cm

If AB = 7.4 cm,

6/4 = 7.4 / AC

AC = 7.4(4) / 6

AC = 29.6 / 6

AC = 4.94 cm (shortest possible length of the third side of the triangle)

If AC = 7.4 cm

6/4 = AB/7.4

AB = 6(7.4)/4

AB = 44.4/4

AB = 11.1 cm (longest possible length of the third side of the triangle)

List 3 points that are on the line 5y= 3x - 7.

We know that the y-intercept is (0, -7)

We know that slope = 3 and slope = rise / run or 3 y for every 1 x

We can add 1 for the x and 3 for the y: (0, -7) to (1, -4).

We can do that again:add 1 for the x and 3 for the y: (1, -4) to (2, -1).

The recipe of the junk calls for 16/7 cups of sugar

From the question, the given parameters are:

Total number of cups = 8

Let the number of cups of sugar be x and the number of cups of flour be y

So, we have the following equation

x + y = 8

Also, we have:

The recipe uses 1/4 cup more sugar, so the amount of sugar equals half the amount of flour

This means that

(1 + 1/4) * x = 1/2 * y

Evaluate the sum and the products

So, we have

5/4x = 1/2y

Make y the subject

y = 5/2x

Substitute y = 5/2x in x + y = 8

x + 5/2x = 8

Evaluate the sum

3.5x = 8

Divide by 3.5

x = 16/7

Hence, the cups of sugar is 16/7

Based on the annuity payment that Marie will make and the number of years, the nt value that she will use in her formula is 360 months.

The nt value is the number of periods that Marie will need to pay her annuity payment. This value can be yearly, monthly, weekly and even daily.

As the mortgage compounds monthly in this instance, the nt value will need to be monthly as well.

To find the nt value, the formula is:

The slope of line passing through the pair of points (4,3) and (2,2) is 1/2.

Slope is simply expressed as change in y-values over the change in x-values.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point 1( 4,3 )

Point 2( 2,2 )

Slope m = ?

Plug the given coordinates into the slope formula and solve for m.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 2 - 3 )/( 2 - 4 )

Slope m = ( -1 )/(-2 )

Slope m = ( 1 )/( 2 )

Slope m = 1/2

Therefore, the slope of the line segment with the given coordinates is 1/2.

By using the elimination method,  the numbers are 11 and 30

Consider the first number as x and the second number as y

Sum of 5 times the first number and 6 times the second number is 235

The linear equation will be

5x+6y = 235

The difference between 7 times the first number and 17 is 2  times the second number

7x-17 = 2y

Rearrange the terms

7x-2y = 17

The both equations are

5x+6y = 235

7x-2y = 17

Multiply the first equation by 2 and second equation by 6

10x+12y = 470

42x-12y = 102

Here we have to use the elimination method

Add both equation and y term will cancelled

10x+42x = 470+102

52x = 572

x = 11

Substitute the value of x in any equation

5x+6y =235

5(11)+6y = 235

55+6y = 235

6y = 180

y = 30

Hence, by using the elimination method,  the numbers are 11 and 30

When an image is dilated by a factor of 3, the statement about the image of the figure that is true is Both the area and the perimeter increase.

When a shape is dilated, the effect on the shape is that its dimensions are made to be longer. For instance, a shape dilated by 2 would see all its dimensions increase by 2.

In the case of a figure that is dilated by a factor of 3, it means that the shape would increase by 3 in size.

The effect of this is that the perimeter would increase by 3. The area of the figure would also increase thanks to the increase in dimensions by 3.

the height in the first case will be 191 cm and the weight in the second case will be 106 kg.

We are given the function as:

BSA = √( w h / 3600)

where:

h = height

w = weight

BSA = body surface area

1) Now, for w = 68 kg and BSA = 1.9, we get the height as:

1.9 = √( (68) h / 3600)

3.61 = 68 h / 3600

12,996 = 68 h

h = 12996 / 68

h = 191.12 cm

h ≈ 191 cm

2) for h = 165 cm and BSA = 2.2, we get the weight as:

2.2 = √( w (165) / 3600)

4.48 = 165 w / 3600

17424 = 165 w

w = 17424/ 165

w = 105.6 kg.

w ≈ 106 kg

Therefore, we get that, the height in the first case will be 191 cm and the weight in the second case will be 106 kg.

a. Absolute value function the reference beam is g(x) = |8x/5|.

b. g(x) = +8x/5 ; x < 5 and g(x) = -8x/5 > 5.

For the given function;

Part a: The reference beam is passing from the points;

(x₁, y₁) = (5, 8)

(x₂, y₂) = (0, 0)

Then the slope of the line is -

m = (y₂ - y₁)/(x₂ - x₁)

Put the values ;

m = (0 - 8)/(0 - 5)

m = 8/5

The equation of the line is;

y - y₁ = m(x - x₁)

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

y = 8x/5

Or in absolute modulus function for the path of reference beam; y = |8x/5|.

Part b: absolute function in terms of piecewise function;

You want the total cost of a $27 meal after 8% tax is added.

The amount of added tax is found by multiplying the meal cost by the tax rate:

The total cost is the meal cost plus the tax:

  $27 +2.16 = $29.16 . . . . actual cost of the meal
