When triangle ABC is dilated to triangle A'BC then the line A'B' has the equation 2z+ 3y = 10.

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline. No matter how far we extend a parallel line, it will never meet another parallel line.

Given that the triangle ABC is dilated to get the triangle A'BC.

If the triangle is dilated then, AB is parallel to A'B'.

So, the slopes of the two line are equal.

The equation of the AB is 2x + 3y = 5.

Converting into the standard equation of line:

y = - 2/3 x + 5/3

The slope of the line is -2/3.

From the given options, the line that has slope -2/3 when converted to standard form is:

2z+ 3y = 10

Hence, when triangle ABC is dilated to triangle A'BC then the line A'B' has the equation 2z+ 3y = 10.

The updated median is 56.37 and the updated IQR is 17.66.

The median is the value in the middle of a data set, meaning that 50% of data points have a value smaller or equal to the median and 50% of data points have a value higher or equal to the median. For a small data set, you first count the number of data points (n) and arrange the data points in increasing order.

Given that, one employee recorded the measurements for the lengths of 55 different wood boards.

Median =58.37 and IQR=19.66

Someone discovers the measuring tape used started at 2 inches instead of 0.

The interquartile range is given by the difference between the 75th percentile(value that is greater than 75% of the measures) and the 25th percentile.

This means that each piece of wood is actually 2 inches shorter than the value recorded by the employee.

This means that the length of each wood is less than 5. However, the difference between the 75th percentile and the 25th percentile will stay the same, since both were subtracted by 2.

So, IQR=19.66-2 =17.66

Therefore, the updated median is 56.37 and the updated IQR is 17.66.

Answer:

  7.  12.2 ft

  8.  7.07 m

  9.  6.06 in

Step-by-step explanation:

You want the hypotenuse of at right triangle with legs 7 and 10 ft, the diagonal of a square with perimeter 20 m, and the altitude of an equilateral triangle with side length 7 inches.

These problems all make use of the Pythagorean theorem, which tells yo the relation between sides a, b and hypotenuse c of a right triangle is ...

  a² +b² = c²

The length of the leash (c) is ...

  c² = (7 ft)² +(10 ft)² = 149 ft²

  c = √149 ft ≈ 12.2 ft

The leash is about 12.2 feet long.

Each side of the square is 1/4 of the perimeter, so is 5 m. The diagonal is the hypotenuse of a right triangle with legs that length. Its measure is ...

  c = √(5² +5²) = 5√2 ≈ 7.07 . . . . meters

The length of the diagonal is about 7.07 meters.

The altitude of an equilateral triangle is a perpendicular bisector of one side. Its length is ...

  b = √(c² -a²)

  b = √(7² -3.5²) = √36.75 ≈ 6.06 . . . . inches

The altitude of the triangle is about 6.06 inches.

A cuboid has 6 faces and the formula for its total surface area is:

2lw + 2lh + 2wh, where l is the length, w is the breadth, and h is the height.

Given the total surface area of 1168 cm² and the length and breadth being 16 cm and 14 cm, respectively:

2(16)(14) + 2(16)h + 2(14)h = 1168

Expanding the expression:

448 + 32h + 28h = 1168

Combining like terms:

60h = 720

Dividing both sides by 60:

h = 12 cm

So the height of the cuboid is 12 cm.

The area of the figure in this problem is given as follows:

A. 30 in².

The area of a triangle is given by half the multiplication of the base length by the height of the triangle.

Applying the Pythagorean Theorem, we can obtain the missing side length, as follows:

4² + x² = 6²

x² = 36 - 16

x² = 20

x = square root of 20

x = 4.47.

For a right triangle, one side is considered the height of the other, hence the sides are:

Hence the area of the triangle is then obtained as follows:

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

a) 75°F

b) 45°C

c) -20°C

Conversion formulas:

C = (F - 32) / 1.8

F = 1.8C + 32

Now,

75°F

C = (F - 32) / 1.8

C = (75 - 32) / 1.8

C = 23.8°C

45°C

F = 1.8C + 32

F = 1.8 x 45 + 32

F = 113°F

-20°C

F = 1.8C + 32

F = 1.8 x (-20) + 32

Answer:

I also believe it is -4.9 but I may be mistaken

Step-by-step explanation:

7. m<2 = 138° based on the definition of vertical angles.

8. m<3 is supplementary to angle 8

9. The measure of angle 2 = 50°

10. The value of x = 20

A supplementary angle is a pair of angles whose sum is equal to 180 degrees. In other words, two angles are supplementary if they add up to a straight angle.

For example, if one angle measures 70 degrees, its supplement would be 180 - 70 = 110 degrees.

7. m<2 = 138° (reason: vertical angles are equal).

8. m<3 is supplementary to angle 8 because angle 3 and 5 are supplementary, and angle 5 is congruent to angle 8.

9. 5x + 55 = 2x + 100 (corresponding angles are equal)

Find x:

5x - 2x = -55 + 100

3x = 45

x = 15

m<2 = 180 - (5x + 55) (linear pair is equal to 180 degrees)

Plug in the value of x

m<2 = 180 - (5(15) + 55)

m<2 = 180 - 130

m<2 = 50°

10. 45 + 5x + 35 = 180 (supplementary angles)

5x + 80 = 180

5x = 180 - 80

Answer: Let's call the length of the rectangular court "L" and the width "W". Then, the perimeter of the court is 2 * (L + W) = 148 feet, so 2 * L + 2 * W = 148 feet.

And, according to the coach's estimate, the athlete ran a total of 4 * L + 7 * W = 353 feet.

We can use these two equations to find the dimensions of the court. Solving the first equation for W:

W = (148 - 2 * L) / 2.

Substituting this expression for W into the second equation:

4 * L + 7 * (148 - 2 * L) / 2 = 353

Expanding and simplifying the right side of the equation:

4 * L + 74 - 7 * L = 353

-3 * L = -279

L = 93 feet.

Finally, using the expression for W from the first equation:

W = (148 - 2 * L) / 2 = (148 - 2 * 93) / 2 = 32 feet.

So the dimensions of the sports court are 93 feet by 32 feet.

The differentiation of the f(x) = g(x)/h(x), using the quotient rule, indicates that the value of f'(2) = 20/81

The Quotient Rule for finding the derivative of a ratio of two functions, [tex]f(x) = \frac{g(x)}{h(x)}[/tex] that are differentiable is presented as follows;

[tex]f'(x) = \frac{h(x) \cdot g'(x) - g(x) \cdot h'(x)}{h(x)^2}[/tex]

The equation of the lines are found as follows;

The points on the line g(x) are; (1, 2), and (3, 6)

Therefore, we get;

Slope of the line = (6 - 2)/(3 - 1) = 2

Equation of the line is; y - 2 = 2·(x - 1) = 2·x - 2

y - 2 = 2·x - 2

y = 2·x - 2 + 2 = 2·x

The equation of the line is presented as follows;

g(x) = 2·x

Points on the graph of the function h(x) when x = 2 are; (2.5, 5), and (0, 2.5)

Slope of the graph of h(x) when x = 2 is; (2.5 - 5)/(0 - 2.5) = 1

The equation of the line is therefore; y - 5 = 1·(x - 2.5) = x - 2.5

y - 5 = x - 2.5

y = x - 2.5 + 5 = x + 2.5

h(x) = x + 2.5

f(x) = g(x)/h(x)

The value of f'(x) using the quotient rule, is therefore;

f'(x) = (h(x)·g'(x) - g(x)·h'(x))/(h(x))²

g'(x) = 2

h'(x) = 1

Therefore;

f'(x) = ((x + 2.5)×2 - 2·x  × 1)/(x + 2.5)² = (2·x + 5 - 2·x)/((x + 2.5)²)

(2·x + 5 - 2·x)/((x + 2.5)²) = 5/(x + 2.5)²

f'(2) = 5/(2 + 2.5)² = 20/81
