A solid right pyramid has a square base with an edge length of x cm and a height of y cm. Which expression represents the volume of the pyramid? xy cm^3 x^2y cm^3 xy^2 cm^3 x^2y cm^3
For our pyramid, this gives us the volume of the pyramid (1/3)x²y.
Let the length of base be x and height be y
Volume of pyramid = [tex]\frac{1}{3}[/tex]× l× b× h
The volume of a right rectangular prism is found by finding the area of the base and multiplying by the height. This is because there are "layers" of the base from the bottom to the top, making the height the number of "layers."
However, in a pyramid, the shape comes to a point. This makes the volume of a pyramid 1/3 of that of the corresponding prism.
For our pyramid, the area of the base would be x(x) = x².
There are y layers of this base, so this would be x²y.
Since it is a pyramid, this gives us the volume of the pyramid (1/3)x²y.

Solve the given differential equation by separation of variables. csc(y) dx + sec2(x) dy = 0
The given differential equation with variable separation will be cosy = -1/2 sin2x + C.
What is a differential equation?A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions.
Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.
Due to the prevalence of these relationships, differential equations are widely used in many fields, including engineering, physics, economics, and biology.
So, we have the differential equation:
csc(y) dx + sec2(x) dy = 0
We, are aware that:
csc(y) = 1/ siny
sec(x) = 1/ cosx
We can also write it:
dx/siny = dy/cos2x
Cross multiplication with variable separation:
siny dy = cos2x dx
Differentiate:
cosy = -1/2 sin2x + C
As a result, the given differential equation with variable separation will be
cosy = -1/2 sin2x + C.

Answer:
f(x) = (1/5)x - (2/5)
Step-by-step explanation:
The linear function can be written in the form of f(x) = mx + b, where m is the slope and b is the y-intercept.
To find the rule for the linear function when x=-10, y=-1, when x=0, y=1 and when x=10, y=3, we can use the two points method.
We can start by finding the slope (m) of the function using the following formula:
m = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are two points on the line.
Using the point (-10, -1) and (10, 3) we get:
m = (3 - (-1)) / (10 - (-10)) = 4/20 = 1/5
Now that we know the slope, we can use the point-slope form of the equation of a line to find the equation of the line:
y - y1 = m(x - x1)
Plug in one of the points and the slope that we found:
y - (-1) = (1/5)(x - (-10))
y = (1/5)x - (2/5)
So the equation of the linear function is f(x) = (1/5)x - (2/5)
This is the rule of the linear function when x=-10, y=-1, when x=0, y=1 and when x=10, y=3.

Answer
212
because I added the 98,4,100,10
Answer:
This question is based on the concept of mean. Therefore, the scores for the four games were 97, 98, 98, 107.
Given:
Sue played four games of golf. For these games her modal score was 98 and her mean score was 100. Her range of scores was 10.
According to the question,
If the modal score is 98 then, there must be two games where she scored 98.
The mean is the total of all of her scores divided by the number of games,
We get,
98+98+x+y=400
x+y= 204
As it is given that, the range is 10 and x is the lowest and y is the highest we can say that:
As we know that, her range of scores was 10,
97+10= 107
Therefore, the scores for the four games were 97, 98, 98, 107.

Answer:
C. No; you would need to know that each pair of diagonals is perpendicular.
Step-by-step explanation:
It is not sufficient to establish that MNOP and TQRS are congruent parallelograms given that MO=TR and NP=QS. Parallelograms that are congruent have the same size and form. A common method for demonstrating that two parallelograms are congruent is to use one of the following criteria:
SSS (Side-Side-Side) : If all three pairs of corresponding sides are congruent.
SAS (Side-Angle-Side): If two pairs of corresponding sides and the included angle are congruent
ASA (Angle-Side-Angle): If two pairs of corresponding angles and the included side are congruent
HL (Hypotenuse-Leg): If the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle
CPCTC (Corresponding parts of Congruent Triangles are Congruent)
Given that we only know that MO=TR and NP=QS, we do not have enough information to prove that the parallelograms are congruent. It is missing information about the angles and the diagonals of the parallelograms.
In addition to that, we need to know that the diagonals of the parallelograms bisect each other. If this is the case, then we can use HL to prove that the parallelograms are congruent.
3 pairs of jeans and 6 shirts costs 104.25 dollars. The cost of 4 pairs of jeans and 5 shirts is 112.15 dollars. Find the cost of each pair of jeans and each shirt?
Answer:
j=16.85
s=8.95
Step-by-step explanation:
j=jeans s=shirt
3j+6s=104.25
4j+5s=112.15
working:
3j+6s=104.25 dollars
4j+5s=112.15 dollars
(get j to be the same)
12j+24s=417 dollars
12j+15s=336.45 dollars
(subtract them)
9s=80.55 dollars
s=8.95 dollars
(substitute in)
(3 x j)+(6x8.95)=104.25 dollars
3 x j= 104.25-(6x8.95)
j=50.55/3 (50.55 divided by 3)
j=16.85 dollars
substitute in to double check
(3 x 16.85) + (6 x 8.95) = 104.25 dollars
check with the other equation and it works also, so that must be the values of j and s (jeans and shirt)
(4 x 16.85) + (5 x 8.95)=112.15 dollars
j=16.85
s=8.95
let $s$ be the set of all real numbers $\alpha$ such that the function\[\frac{x^2 5x \alpha}{x^2 7x - 44}\]can be expressed as a quotient of two linear functions. what is the sum of the elements of $s$?
The sum of all the elements of set S is -(220/7).
To express the function (x^2+5x +y)/(x^2+7x - 44) as a quotient of two linear functions, the denominator must be a factor of the numerator. In other words, (x^2+7x - 44) must divide (x^2+5x +y) without leaving any remainder. To find the sum of the elements of S, we can set the numerator equal to the denominator multiplied by a constant and solve for y.
x^2+5x +y = c(x^2+7x - 44)
The constant c is a scalar value.
x^2+5x +y = cx^2 +7cx - 44c
we can now equate the coefficients of x^2 and x.
1 = c
and, 5 = 7c
now we can solve for c:
c = 5/7
Now we can substitute the value of c back into the equation:
x^2+5x +y = (5/7)(x^2+7x - 44)
=> x^2+5x +y = (5/7)x^2 + (35/7)x - (220/7)
we can now equate the constant terms:
y = -(220/7)

What does the slope intercept form mean?
The formula for a straight line, written as y = mx + b, where m denotes the line's slope and b its y-intercept. We can see that the y-intercept of the line in our equation, y = 7 x + 4, is 4.
In the slope-intercept form, the equation for the line is expressed as follows: y = mx + b, where m denotes the slope and b the y-intercept. We can observe that the line's slope is 3 from our equation, y = 3 x + 5.
All lines passing thru the origin should have a slope of y = mx + c
In this case, since the slope is 1/7 , the line will be y = 1/7x
Thus, it could observe which is the only point that satisfies this equation of the line out of all the points.

If we changed the 2 to a 5 in the domain restriction , what would happen to the graph?
If we changed the 2 to a 5 in the domain restriction, the graph would become a line that extends infinitely in both directions.
What is domain restriction?Domain restriction in mathematics is the process of restricting the possible values of a variable to a certain range or subset of values. This can be done by limiting the domain of a function or equation. In general, domain restriction involves identifying a range of values for which the function or equation is valid and then discarding any values that do not fall within that range. For example, if a function was defined for all real numbers, but the domain was restricted to only positive values, then the function would no longer be valid for negative numbers.
If we changed the 2 to a 5 in the domain restriction, the graph would become a line that extends infinitely in both directions. This is because the equation y = 2x + 5 is equivalent to y = 5x, which is a line with a slope of 5 and a y-intercept of 5.
