To find out how many bicycles John can assemble in 1 hour, you can use the formula:

rate = work/time

where rate is the number of bicycles John can assemble in 1 hour, work is the total number of bicycles he assembled, and time is the total time it took him to assemble the bicycles.

In this case, the work is 10 bicycles and the time is 8 hours. So, we can substitute these values into the formula:

rate = 10 bicycles / 8 hours

rate = 1.25 bicycles/hour

So John can assemble 1.25 bicycles in 1 hour, assuming he works at a consistent pace.

The inequality equations is

a) The point ( -9 , 4 ) lies on the inequality relation

b) The point ( 6 , -2 ) lies on the inequality relation

c) The point ( 0 , -4 ) does not lie on the relation

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

a)

Now , let the first point be represented as P ( -9 , 4 )

The shaded region is below 4 in the y axis and less than -4 in the x axis

So , the point ( -9 , 4 ) does lies on the inequality equation graph

b)

Now , let the first point be represented as Q ( 6 , -2 )

The shaded region is below -8 in the y axis and less than 8 and more than 4  in the x axis

So , the point ( 6 , -2 ) does lies on the inequality equation graph

c)

Now , let the first point be represented as R ( 0 , -4 )

The shaded region is above -8 in the y axis and more than -4 in the x axis and less than -1

So , the point ( 0 , -4 ) does not lie on the inequality equation graph

The length of the rectangle is 20 and the width is 13.

The perimeter of a rectangle = 2(length + width)

Width = w

Length = 2w - 6

90 =  2(w + 2w - 6)

In order to determine the value of w, take the following steps:

Divide both sides of the equation by 2

90/2 = w + 2w - 6

45 = w + 2w - 6

Combine and add similar terms:

45- 6 = w + 2w

39 = 3w

Divide both sides of the equation by 3

w = 39/3

w = 13

In order to determine the length, substitute for w in the equation that represents the length.

Length = 2(13) - 6

= 26 - 6

Point T becomes (18, 2), which equals T', when we transform STUV using the technique above.

Four distinct approaches to modify the position and/or shape of a point, line, or geometric figure are collectively referred to as transformations. The Pre-Image of the object is its initial shape, while the Image, after transformation, is the final shape and location of the thing.

The movement of two-dimensional figures about a plane or coordinate system is described by mathematical transformations. A preimage, also known as an inverse image, is a two-dimensional shape that exists without any change. After transformation, the figure is shown in the image.

If we pay attention to the transformation, it is obvious that every point in the rectangle JKLM is changed to a point that is 13 units to the right and 3 units to the bottom.

The T in STUV is currently at (5, 5).

If the frame has 2 inches of width and its area is 208 inches of square. The dimensions of square without frame is 6.75 and 13.50.

Let the width of rectangle without frame is b.

Let the height of rectangle without frame is h.

Since the base of a square without frame is the double of its height. So

b = 2h...............(1)

The frame has 2 inches of width, so;

The width of rectangle with frame = b + 4

The height of rectangle with frame = h + 4

The area of the rectangle with frame = 208  inches of square

The formula of area of rectangle

A = Height × Width

(h + 4) × (b + 4) = 208

Putting the value of b from the equation 1

(h + 4) × (2h + 4) = 208

Simplify

h(2h + 4) + 4(2h + 4) = 208

2h^2 + 4h + 8h + 16 = 208

2h^2 + 12h + 16 = 208

Subtract 208 on both side, we get

2h^2 + 12h - 192 = 0

Taking common 2 from the equation, we get

h^2 + 6h - 86 = 0

After factoring the equation we get

h = (−3+√95, −3−√95)

h = 6.75, -12.75

The height can't be negative so we use the positive value of h.

Now putting the value of h in the equation 1.

Answer:  it takes 7.5 seconds for the object to reach the ground.

Step-by-step explanation:

The equation for the height of the object is h=-16t^2+900. To find the time when the object reaches the ground, we need to find the value of t when h=0.

Therefore, we can set h=-16t^2+900 = 0 and solve for t:

-16t^2+900 = 0

-16t^2 = -900

t^2 = 56.25

t = sqrt(56.25)

t = 7.5

So, it takes 7.5 seconds for the object to reach the ground.

The equation of a quadratic equation with a vertex and a point is

y = 1/4 (x - 11)² + 2

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 6 is an equation.

We have,

Vertex = (11, 2)

Point = (9, 3)

The equation of a quadratic equation with a vertex and a point is

y = a (x - h)² + k

Where (h, k) is the vertex and (x, y) is the point.

Now,

(11, 2) = (h, k)

(9, 3) = (x, y)

Substitute.

y = a (x - h)² + k

3 = a (9 - 11)² + 2

3 = a x 4 + 2

3 = 4a + 2

3 - 2 = 4a

I disagree with Brie.

Only the bean plant has a proportional relationship. The sunflower does not have a proportional relationship.

In a proportional relationship, the ratio of the dependent variable (height) to the independent variable (number of days) is constant. In this case, the ratio of height to number of days is not constant for both plants.

For the bean plant, the ratio of height to number of days is 0.25, which is constant. This means that the bean plant grows by 0.25 inches per day.

For the sunflower, the ratio of height to number of days changes as the number of days increases, it starts with 10 and increases by 0.02 each day. This means that the growth rate of the sunflower is not constant, it starts with 10 and increases by 0.02 inches per day.

The equation for the graph after the shift would be y = x + 1. The answer is y = x + 1.

What happens when a function is shifted vertically?

Because this transformation involves adding a positive or negative constant to the function, a vertical shift, which moves the graph up or down, is the simplest shift. In other words, regardless of the input, the output result of the function receives the same constant.

The y-value adjusts when a function shifts vertically. While the y-value modifies the shift's magnitude, the x-value remains constant.

We add the value to the y-term if it changes upward. We shall deduct that amount from the y-term if it shifts downward.

The simplest transformation is a vertical shift, which entails moving the graph up or down. This is because this transformation only requires changing the function's sign from positive to negative.

The only variable that alters in vertical shifts of the fundamental linear equation y = mx + b is the b value, or the y-intercept.

The graph shown above is the graph of the parent function y=x after a vertical shift up 1 unit.

The inequality is y ≥ 1/2x.

We must first identify the linear equation that describes the line in the graph in order to determine the inequality it reflects.

So, using the two points (0, 0) and (2, 1), we first get the slope of the line:

m = y2 - y1 /x2 - x1 = 1-0 / 2-0 = 1/2

Now, we can determine the linear expression using one point, the slope, and the slope-point formula.

y - y1 = m( x - x1)

y - 0 = 1/2(x - 0 )

y = 1/2 x

Then, to evaluate the linear equation, we only need to select a test point from the shaded region, which will be (0,1):

y = 1/2 x

1 = 1 / 2 (0)

1 = 0

Because 1 is greater than 0 and the line is solid, we can infer that the inequality sign is in the proper position.

Therefore, the inequality is y ≥ 1/2x.
