The percent of change when 51 is increased to 98, then there have increment of 92%. So the option d is correct.

The difference between a new and old amount, given as a percentage, is known as a percent change.

Calculating percent change involves determining the difference between the old and new quantities, dividing that difference by the old quantity, and multiplying that result by 100.

The number 51 is raised to 98; calculate the percentage change.

To start, subtract the new quantity from the previous one to determine the difference. 98 - 51 = 47, therefore the difference is 47.

The difference, 47, is then divided by the old amount, 51, yielding a result of 47/51=0.92.

Lastly, multiply the decimal by 100 × 0.92 to get the percentage change, which is increment of 92%.

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.

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

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.

b = 2×6.75

b = 13.50

Gary would need 15.2 oz glue and 7.6 oz of glitter to make 4 bottles.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

We have the information that,

Amount of glue needed for 1 bottle = 3.8 oz

Amount of glitter needed for 1 bottle = 1.9 oz

We have to find the amount of glue and glitter for 4 bottles.

Finding the product for 4 bottles.

Amount of glue needed for 4 bottles = 3.8 × 4 oz = 15.2 oz

Amount of glitter needed for 4 bottles = 1.9 × 4 oz = 7.6 oz

Hence Gary will need 15.2 oz glue and 7.6 oz of glitter to make 4 bottles.

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

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.

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.

Given that the surface area of a cylinder is 24π m². The distance around the base of the cylinder is 3π meters and the diameter of the base of the cylinder is 4 meters.

The height of the cylinder will be calculated as:-

Surface area = 2πrh

24π = 2πrh

r x h = 12

The diameter is 4 meters so the radius is 2 cm.

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.
