Sixty three is the product of nine and a number which is seven
What is multiplication?Multiplying in math is the same as adding equal groups.
The number of items in the group grows as we multiply. Parts of a multiplication problem include the product, the two components, and the answer.
In the multiplication problem involving 63 as the product of 9 and another number
let the number be x
9 * x = 63
9x = 63
isolating x by dividing both sides by 9
9x / 9 = 63 / 9
x = 7

Write a quadratic given a vertex (11,2) and a point (9,3)
The equation of a quadratic equation with a vertex and a point is
y = 1/4 (x - 11)² + 2
What is an equation?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
a = 1/4
Now,
The equation of a quadratic equation is y = 1/4 (x - 11)² + 2.

An object is dropped from 28 feet below the tip of the pinnacle atop a 928-ft tall building. The height h the object after t seconds is given by the equation h=-16t^(2)+900. Find how many seconds pass before the object reaches the ground.
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 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.

Consider the function f(x). Select all of the following that include a vertical stretch of f(x).
The vertical stretch of f(x) will be -2f(x), 5.5f(x) - 1, 7f(x)
As is well known, the vertical stretch of f(x) occurs when the value of the parameter is changed in the following general form:
When a constant c with a value larger than one is scaled across the board of a function, it results in a vertical stretch. It is written as the vertical stretch from the original function f(x) to the new, stretched function g(x)=cf(x) where c>1 g ( x ) = c f ( x ) where c > 1.

The graph of y = In(x) was transformed by shifting 8 units left and 12 units up. Write an equation
The equation of the translated function for this problem is given as follows:
y = ln(x + 8) + 12.
What are the translation rules?The four translation rules are defined as follows:
Left a units: g(x) = f(x + a).Right a units: g(x) = f(x - a).Up a units: g(x) = f(x) + a.Down a units: g(x) = f(x) - a.The parent function in this problem is given as follows:
y = ln(x).
The translations in this problem, and their effects, are given as follows:
8 units left: x -> x + 8.12 units up: y -> y + 12.Hence the translated function is defined as follows:

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%.

La base de un cuadrado sin marco mide el doble de su altura si el marco tiene 2 pulgadas de ancho y su área es de 208 pulgada cuadradas encuentre las dimensiones del cuadrado sin marco
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

What is a cylinder?One of the most fundamental curvilinear geometric shapes, a cylinder has traditionally been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry. In some modern branches of geometry, a cylinder may also be defined as an infinite curvilinear surface.
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.
