Which variation is represented by this situation:
A building that is 6 stories tall has a shadow that is 22 meters long.
How many stories tall is a building with a shadow that is 40 meters
long? Is it inverse variation or direct variation?
When a building is 40 meters long in shadow cast by another building of the same height, there are 10 levels there.
what is direct variation ?equation that can be used to explain the mathematical relationship between two variables, where one variable is equal to a constant multiplied by the other. A direct variation's (proportional relationship's) graph is a straight line that pierces the origin. On a graph of direct variation, the graph will always pass through (1, k), where k is the proportionality constant. Direct variation refers to a change in one quantity that directly affects the other. The complete opposite of this is inverse variation.
The equation that describes this variation is:
h =kx
1st Data 2nd Data
s=22 m s = 40 m
h=6 stories h = find 2nd
k=find 1st k = 0.27 story/m
Find k: Find h :
h=kx h = kx
6 stories=k(22 m) h = ( 0.27 story/m ) ( 40 m)
k=6 stories/22 m h = 10 stories
k=0.27 story/m
so its direct variation .

The midpoint of line CD is M(-3,-7). If the coordinates of C are (-2, -10), what are the coordinates of D?
Answer:
D = (-4, -4)
Step-by-step explanation:
Given;
midpoint of line CD = M(-3, -7)
coordinate of C = (-2, -10)
The coordinate of D is calculated as follows;
C(-2, -10)---------------------M(-3, -7)--------------------D
[tex]M = \frac{D_1 + C_1}{2} \ , \ \frac{D_2 + C_2}{2} \\\\(-3, \ -7) = \frac{D_1 + (-2)}{2} , \ \frac{D_2 + (-10)}{2} \\\\(-3, \ -7) = \frac{D_1 \ - \ 2}{2} , \ \frac{D_2 -10}{2} \\\\-3 = \frac{D_1 \ - \ 2}{2} \ \ ----(1)\\\\-7 = \frac{D_2 -10}{2} \ -----(2)\\\\From \ (1): 2(-3) = D_1\ - \ 2\\\\-6 = D_1 - 2\\\\-6 + 2 = D_1\\\\-4 = D_1\\\\From \ (2) : \ 2(-7) = D_2 - 10\\\\-14 = D_2 - 10\\\\ -14 + 10 = D_2\\\\-4 = D_2\\\\The \ coordinate \ of \ D = (D_1\ , \ D_2)\\\\D = (-4 \ , \ -4)[/tex]
Therefore, the coordinate of D = (-4, -4)

If $3x 7\equiv 2\pmod{16}$, then $2x 11$ is congruent $\pmod{16}$ to what integer between $0$ and $15$, inclusive
2x 11 is congruent to 13 mod 16, if 3x 7 is congruent to 2 mod 16.
If 3x 7 is congruent to 2 mod 16, then 2x 11 is congruent mod 16 to what integer between 0 and 15, is inclusive.
To find the solution of 2x 11 congruent mod 16, given 3x 7 congruent to 2 mod 16, we can first use the given equation to find the value of x and then substitute it into the second equation.
First, we can solve for x in the given equation:
3x 7 is congruent to 2 mod 16
3x is congruent to 2 mod 16
x is congruent to 6 mod 16
Now that we know that x is congruent to 6 mod 16, we can substitute it into the second equation:
2x 11 is congruent to 2(6) 11 which is congruent to 13 mod 16
So the solution is that 2x 11 is congruent to 13 mod 16.

How do you find the parent function of a line?
The parent function of a line (usually of the form y = ax + b) is y = x.
The most basic form of a function is a parent function. Its essential shape is not changed in any manner. In mathematics, some graphs are frequently seen. Because of this, the graphs of quadratic functions, square roots, absolute values, cubics, and cube roots are among the original, widespread functions that are referred to as parent graphs.
For instance, you should still be able to identify the parabola that has undergone various transformations when you view a u-shaped graph that has been inverted and stretched vertically.
Linear FunctionLinear functions have x as the term with the highest degree and a general form of y = a + bx. All linear functions have a straight line as a graph. The parent function of linear functions is y = x, and it passes through the origin. The domain and range of all linear functions are all real numbers.
These functions represent relationships between two objects that are linearly proportional to each other.
Therefore, the parent function of a line (usually of the form y = ax + b) is y = x.

A gardener has 400 feet of fencing t0 fence in a bordered rectangular garden: One side of the garden Is river and so it does not need any fencing: river garden What dimensions would guarantee that the garden has the greatest possible area? shorter side: ft (feet) longer side: (feet) greatest possible area: (square-feet) Submit Question
The shorter side should be 200 ft and the longer side should be 200 ft. This would give the garden the greatest possible area of 40,000 square-feet.
1. The area of a rectangle can be calculated by multiplying the length and width together.
A = L * W
2. We know that the total amount of fencing is 400 ft.
3. We also know that one side of the garden is a river and so it doesn't require fencing.
4. Therefore, the remaining fencing must be divided equally between the two other sides of the garden (200 ft per side).
5. We now know that the length and width of the garden are both 200 ft.
6. Plugging these values into the area equation, we get:
A = 200 ft * 200 ft = 40,000 sqft
7. Therefore, the greatest possible area of the garden is 40,000 square-feet..

the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (3, 4 )
m = [tex]\frac{4-2}{3-0}[/tex] = [tex]\frac{2}{3}[/tex]

A recipe calls for 2 2/3 cups of flour to make two regular batches of cookies. Shiloh needs to make multiple batches of cookies. Represent this situation with an equation. What is the constant of proportionality? How can you identify it in an equation? How can you use an equation to determine if a relationship is proportional?
This situation can be represented with an equation as y = mx + b. The constant of proportionality (m) is a number that represents how much flour is needed for each additional batch of cookies. If the equation is in the form y = mx + b, then the relationship is proportional.
Shiloh needs to make multiple batches of cookies from a recipe that calls for 2 2/3 cups of flour to make two regular batches. To represent this situation in an equation, the equation is y = mx + b, where y is the amount of flour needed for the number of batches (x) Shiloh is making, m is the constant of proportionality, and b is the initial amount of flour needed (2 2/3 cups).
The constant of proportionality (m) in the situation above is the measure of how much flour is needed for each additional batch of cookies. For example, if the constant of proportionality is 0.75, that means Shiloh would need to add 0.75 cups of flour for each additional batch of cookies.
Therefore, if Shiloh is making three batches of cookies, the equation would be y = 0.75x + 2 2/3, and the total amount of flour needed would be 4 1/8 cups (2 2/3 + 0.75 + 0.75).
By using an equation to represent this situation, it is easy to determine if a relationship is proportional.
If the equation is in the form y = mx + b, then the relationship is proportional.

A general exponential equation is given as,
y = aˣ
Graph 1, the graph shows the exponential decay because the value of the function is getting decreasing for the domain 0 to ∞. For this domain, the value of the function starts from point A which is at 25000 and ends at point B where y = 0, so the range is {25000, 0}.

Jacinta compares the volume of two boxes. Both boxes have a width of 2.5 inches, and a height of 10 inches. The
larger box has a length of 8 inches. The smaller box has a length that is 75% of the length of the larger box.
(a)
Volume of large box =
<
(b) Volume of small box =
(c) What is the difference in the volumes of the two boxes?
(d)
Which units should be used for each of these answers?
Step-by-step explanation:
w(idth) = 2.5 inches for both boxes
h(eight) = 10 inches for both boxes
l(ength)l(arge) = 8 inches
l(ength)s(mall) = 75% of ll (=> of 8 inches)
=> ls = 8 × 75/100 = 2 × 75/25 = 2 × 3 = 6 inches
vl (volume large) = 8 × 2.5 × 10 = 200 inches³
vs (volume small) = 6 × 2.5 × 10 = 150 inches³
the difference of these two volumes is 50 inches³
the units to be used is cubic inches (inches³). we are talking about volumes. not lengths (inches), not areas (inches²).
the reason - for a volume we need to multiply 3 lengths (measured in simple inches). so, inch multiplied by inch is inch². this multiplied by inch again is then inch³.
