What is the median in a triangle?

A line segment that joins a vertex to the mid-point of the side that is opposite to that vertex

The interception point is a barycenter because it's formed by the medians of the triangle. We deduct that those three lines are medians because they divide each side in half.

So, from the interception of these three medians we deduct:

TX=2 XV

XV=TX/2

But, we know VT=60

Also, by the sum of segments: VT=TX+XV

60=TX+(TX/2)

(3 TX/2)=60

TX=120/3=40

Therefore, TX measures 40 inches.

The slope of a line parallel to the line whose equation 8x + 10y = 60 is -4/5

What is Equation of line ?

A straight line's general equation is y = mx + b, where m denotes the gradient or slope and y = b denotes the point at which the line crosses the y-axis. On the y-axis, this value b is referred to as the intercept.

Given the equation,

8x + 10y = 60

We know, the equation of line is in form of

y = mx + b

m = slope and b = y-intercept

Now, evaluate the given equation

8x + 10y = 60

10y = 60 - 8x

y = (60 - 8x) / 10

y = 60/10 - 8x/10

y  = 6 - 4/5x

y = -4/5x + 6

Which is in the form of equation of line

y = -4/5x + 6

Now, from this slope is - 4/5 and y-intercept is 6

Hence, the slope of a line parallel to the line whose equation 8x + 10y = 60 is -4/5

What Does the Area of a Rectangle Mean?

The area is the amount of space occupied by a flat surface with a particular shape. A "number of" square units are used in the calculation (square centimeters, square inches, square feet, etc.) An area is the number of unit squares that can fit inside a rectangle. Examples of rectangular shapes include the flat surfaces of laptop monitors, blackboards, painting canvases, etc. Use the area formula for the rectangle to calculate the area that these objects take up. Think about a rectangle that is 4 inches long and 3 inches wide, for example.

Given That

Rectangle Stables will have total dimensions of 30 yards by 10 yards
Length = 30 yards
Breath = 10 yards
Total Area of stables = Length x Breath
= 30 x 10 = 300 [tex]yard^{2}[/tex]

Area of walkway = 45 [tex]yard^{2}[/tex]

Hence area of horses will be = 300 - 45 = 255 [tex]yard^{2}[/tex]

Now 1 horse occupy = 12 [tex]yard^{2}[/tex]
so 255 [tex]yard^{2}[/tex] can have = [tex]\frac{255}{12}=21[/tex] horses
Hence the Answer is 21 Horses

No this is incorrect. when a triangle undergoes translation, reflection and rotation congruence of the triangle is still maintained however dilation makes the triangle not to be congruent.

Transformation is a term used in mathematics to refer to the movements made by objects.

Transformation is basically of two major divisions

Non rigid transformation are the transformation where the dimension or size of the object will be different from the image, example is dilation

In rigid transformation, the dimensions of the object is maintained through out the transformation examples of rigid transformation are

Since the transformation types mentioned are all rigid transformation hence all the angles will remain same

Hence we can say that a triangle's congruence is maintained when it is subjected to translation, reflection, and rotation; nevertheless, dilatation renders the triangle incongruent.

The value of x found by expressing the information as an equation is 100

An equation is a statement usually made using mathematical symbols, numbers and variables, that consists of joining two expressions with an 'equals' sign.

The volume of water in the aquifer = 146,000 ft³

The rate at which water exits the aquifer daily = 500 ft³ per day

Rate at which the aquifer is replenished = x ft³ per day

The time it takes the water to be used up = 1 year

The number of days in a year = 365 days

The value of x can be found by expressing the information as an equation as follows;

The sum of the volume of water in the aquifer and the volume of water that replenishes the aquifer in a year, less the water that exits the aquifer in a year is zero, therefore;

Water in the aquifer; 146,000 - 500 × 365 + x × 365 = 0

-36500 + 365·x = 0

365·x = 36500

x = 36500 ÷ 365 = 100

x = 100

The value of x is 100

The water is replenished at 100 cubic feet per day

Answer:

(a^2+3a+1) -(3a^2+5a+(-6)) =4a^2-2a+7

Step-by-step explanation:

So, first of all, we can look at the equation and separate them based on the power of each number, and sense we are subtracting, we need to distribute the negative sign all across the second set of numbers.

So, for a^2 we have

a^2-(x) =4a^2

If we subtract a^2 on each side, we get

-(x) =3a^2 but since we don't want a negative, we divide each side by -1 which gives us that the mystery value must equal -3.

x=3a^2

Next, we got to take the second set of like terms

(x)-5a=-2a

We got to add 5a on each side which gives us

x=3a

Finally, we take the last set of like terms

1+-(x) =7

we subtract one from each side to get

-(x) =6

We don't want x to be negative therefore we divide each side by -1 so it will end out

x=-6

Step-by-step explanation:

The quadratic function that contains the points (-1,1), (0,-2) and (2,4) is f(x) =

2x²-x-2.

To find the quadratic equation we need to put the points in the equation to satisfy it,

The only equation doing it is f(x) = 2x²-x-2 as,

f(x) = 2x²-x-2

For (-1, 1)

1 = 2×(-1)² + 1 -2

1 = 1

Hence (-1,1) satisfies f(x) = 2x²-x-2

For (0, -2)

-2 = 2×(0)² - 0 -2

-2 = -2

Hence (0, -2) satisfies f(x) = 2x²-x-2

For (2, 4)

4 = 2×(2)² -2 -2

4 = 4

Hence (2,4) satisfies f(x) = 2x²-x-2

Regression analysis is a group of statistical techniques used in statistical modelling to identify relationships between a dependent variable and one or more independent variables. The dependent variable is frequently referred to as the "outcome" or "response" variable, or a "label" in machine learning jargon (often referred to as "predictors," "covariates," "explanatory variables," or "features"). The line (or more complex linear combination) that most closely matches the data in terms of a specified mathematical criterion is found in linear regression, the most common type of regression analysis. For instance, the line (or hyperplane) that minimises the sum of squared differences between the real data and that line is determined when using the ordinary least squares approach (or hyperplane).

The amount paid each month is, $503.75

What is monthly payment?

The monthly payment is the sum paid each month to cover the loan's outstanding balance over its term. When a loan is obtained, not only the principal, or the sum that was initially lent, but also the interest accrued, must be repaid.

1) As the discount is 7%.

So he pays, 100 - 7 = 93% of the car value

Now, 93% x 6500 = 6045.

This is the value for one year.

From this we have to find the amount paid for each month.

6045/12 = $503.75

Hence, the amount paid for each month is $503.75.

2) Let, the value of Zlatan's house is $749000 after a increase in the value of house.

So, the total percentage increase price is 107% (100 + 7).

We have to fine the initial value of the house.

So,

Initial value of the house = New value of the house / total percentage increase

                                         = 749000/107%

Initial value of the house = $700000

Hence, the initial value of the house is $700000.

3) Assume that Carol's initial weekly wage be $x.

There is 10% decrease in weekly wage.

So,

10% weekly wage = 10% of x = 0.1x

Here,

New wage after 10% decrease = initial weekly wage - 10% of x.

                                                   = x - 0.1x

                                                   = 0.9x

As given the new weekly wage is $306.

We equate $306 and 0.9x.

So

0.9x = 306

     x =  340

Therefore, the initial weekly wages are $340.

Now to find weekly wage when there is 10% increase.

10% of initial weekly wage = (10/100) x 340 = 34

Hence, Wage after 10 % increase = 340 + 34 = $374

4) Let $2000 is placed into a bank account that pays 3% compound interest per year.

We have to find the amount after two years.

Here, P = $2000,  r = 3% = 0.03, n = 2

Amount = P(1 + r)^n = 2000(1 + 0.03)^2 = 2000(1.03)^2 = 2121.80

Hence, $2121.80 will be in the account after 2 years.

5) Let Mary invests $12000 in a savings account. The account pays 1.5% compound interest per year.

We have to find the value after two years.

Here, P = $12000, r = 1.5%, n = 2

So,

Amount = P(1 + r)^n = 12000(1 + 0.015)^2 = 12000(1.015)^2 = 12362.70

Hence, $12362.70 is the value of her investment after 2 years.
