The transformation is given as:

A reflection across the x-axis

The rule of reflection across the x-axis is

The width of the banner is 8  feets

The banner is in the shape of a rectangle

The length of the banner or the rectangle is 20 feet

the length of the banner or the rectangle is 2.5 times the width

So here we need to find out the value of width of the banner or the rectangle  in feets

Let us assume the width of the banner or the rectangle  to be x feets

So, the length of the banner or the rectangle  would become 2.5 x

by solving this simple linear  equation 20 = 2.5x

                                      [tex]\frac{20}{2.5}[/tex]  = x

so the value of x appears to be 8 feets

The slope of the line AB which passes through the points (4, 5) and B(9, 7) is 2/5.

According to the given question.

We have a line AB containing the points A(4, 5) and B(9, 7).

Here, we have to find the slope of line AB.

As we know that, as we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).

Therefore, the slope of the line AB which passes through the points (4, 5) and B(9, 7)

= (7 - 5)/(9 - 4)

= 2/5

Hence, the slope of the line AB which passes through the points (4, 5) and B(9, 7) is 2/5.

=================================================

Explanation:

The graph is increasing when the curve goes uphill when moving to the right.

This occurs on the interval -2.5 < x < 0 which condenses to the interval notation (-2.5, 0); be sure not to mix this up with ordered pair notation which unfortunately looks identical.

----------

The graph is decreasing when the curve goes downhill when moving to the right.

This happens on two separate intervals of -∞ < x < -2.5 and 0 < x < ∞ which condense to the interval notation (-∞, -2.5) and (0, ∞) respectively.

Joining those two intervals up with the union symbol gets us

m² + n²/p² = 1  is not equation of triangle

Solution :

Triangle :

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted. Equilateral triangle.

Pythagorean triples are any three positive integers that completely satisfy the Pythagorean theorem. The theorem states that in any right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two legs of the right triangle.

m² + n²/p² = 1

Pythagorean triples are a set of 3 positive numbers that fit in the formula of the Pythagoras theorem which is expressed as, a2 + b2 = c2, where a, b, and c are positive integers. Here, 'c' is the 'hypotenuse' or the longest side of the triangle and 'a' and 'b' are the other two legs of the right-angled triangle. The Pythagorean triples are represented as (a,b, c). The most popular example of Pythagorean triples is (3, 4, 5). We can verify that 3, 4 and 5 satisfy the equation a2 + b2 = c2. Let us see how! 32 + 42 = 52 ⇒ 9 + 16 = 25. Observe the right-angled triangle given below which shows the Pythagorean triples, 3, 4, and 5.

We know that ,

1 feet= 0.33 Yard

Given that .

An air conditioning circulate 1 cubic foot per minutes

So it circulates 0.33 Yards per minute .

13.32 yards per minute

Given that an air conditioning system can circulate 360 cubic feet of air per minute. This is the rate of cubic feet per minute. That is,

Rate = volume/time. Which is

360 = volume/ 1

Volume = 360 cubic feet

Convert cubic feet to cubic yard

1 cubic foot = 0.037 cubic yards

Multiply this by 360

Cubic yards = 360 × 0.037

Cubic yards = 13.32

Therefore, if 360 cubic feet can circulate air per minute, this is equal 360 cubic feet of air per minute. how many cubic yards of air can it circulate per minute​ to 13.32 cubic yards of air which can circulate air per minute​

The solution of the given system of equations is (0, -4)

We will use the substitution method.

Given the system of equations:

-3x - y = 4   ............ (1)

4x + 2y = -8   ..........(2)

Add 3x to both sides of (1):

-3x - y +3x = 4 + 3x

-y = 4+3x

Multiply by (-1)

y = -(4+3x)

Substitute y = -(4+3x) into equation (2)

4x + 2y = -8

4x + 2. (-(4+3x)) = -8

4x - 8 - 6x = -8

-2x -8 = -8  (Add 8 to both sides)

-2x -8 + 8 = -8 + 8

-2x = 0

x = 0

Substitute x = 0 into:

y = -(4+3x)

y = -(4+3 . 0) = -4

The solution is (0, -4)

By using trigonometric relations, we will see that:

a = 7/2, b = (7*√3)/2

So the correct option is the second option, counting from the top.

Here we have a right triangle where we only know the value of the hypotenuse and one of the angles, and we want to find the measures of both of the legs (also known as cathetus).

Then we will use the two relations:

cos(θ) = (adjacent cathetus to the angle)/(hypotenuse)

With that relation we can find the value of b:

cos(30°) = b/7

cos(30°)*7 = b = (7*√3)/2

The other relation we will use is:

sin(θ) = (opposite angle to the given angle)/(hypotenuse)

With that we can get the value of a:

sin(30°) = a/7

sin(30°)*7 = a = 7/2

Then the correct option is:

a = 7/2, b = (7*√3)/2

Which is the second option, counting from the top.

The we can draw a rectangle with length = 2 cm and width = 4 cm.

According to the statement

We have to find that the dimensions of the another rectangle.

So, For this purpose, we know that the

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.

From the given information:

The perimeter of a pool is 150 m. The rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. Draw another scale drawing of the pool using the scale 25 m to 2 cm.

Then

From the given rectangle,

Length of the rectangle = 5 cm

Width of the rectangle = 10 cm

Ratio of length : width = 1 : 2

Perimeter of the rectangle = 2(l + b)= 150 cm

l + b = 75 -----(1)

Since, l : b = 1 : 2

b = 2l ------(2)

From equations (1) and (2),

l + 2l = 75

3l = 75

l = 25 m

Width 'b' = 2(25) = 50 m

Now we have to draw a rectangle with a scale = 25 : 2

Therefore, Scale factor = 25/l = 25/2

Scale factor = l = 2cm

Then Similarly,

50/ w= 50/2

w = 4cm

Now we can draw a rectangle with length = 2 cm and width = 4 cm.

So, The we can draw a rectangle with length = 2 cm and width = 4 cm.
