What is combination formula?The combination formula is used to determine how many options there are for choosing things from a collection so that the order in which they are chosen is irrelevant. Combination, to put it simply, is the choosing of items or things from a bigger group when the order doesn't important.
Since order and position doesn't matter in this problem, use the combination formula.
The combination formula is: n! / (n-r)! r!
where n is the total number of items (15 in this case) and r is the number of items being selected at once (5 in this case)
Plugging our numbers into the formula:

The point (2, 90) represents the value that after 2 weeks, Paul's math average is a 90. The
point (4, 50) represents the value that after 4 weeks, Paul's grade has dropped to a 50
because he doesn't do homework and doesn't know how to log into Quizlet. What equation
represents the line of Paul's grade downfall? (5 Points)
y = -0.10x + 130
y=20x-100
y = 20x- 130
y=0.10x+90
y=-20x+90
y=-20x+130
Answers
Answer:
The equation that represents the line of Paul's grade downfall is:
y = (-20)x + 130
This equation states that for every decrease of 1 in the value of x (representing the number of weeks), the value of y (representing Paul's math average) decreases by 20.
Step-by-step explanation:
To find the equation that represents the line of Paul's grade downfall, we can use the two given points to plot the line on a coordinate plane. The point (2, 90) represents the value that after 2 weeks, Paul's math average is 90, and the point (4, 50) represents the value that after 4 weeks, Paul's grade has dropped to 50. We can plot these two points on the coordinate plane as follows:
(2, 90)
(4, 50)
To find the equation of the line that passes through these two points, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope of the line and b is the y-intercept.
To find the slope of the line, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates of the two points, we get:
m = (50 - 90) / (4 - 2)
= -40 / 2
= -20
To find the y-intercept of the line, we can substitute the coordinates of one of the points and the slope into the slope-intercept form of the equation:
y = mx + b
Substituting the coordinates of the point (2, 90) and the slope of -20, we get:
90 = (-20)(2) + b
= -40 + b
= b - 40
Solving for b, we get:
b = 90 + 40
= 130

What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know a line segment parallel to a side of a triangle divides the other two sides in the same ratio.
Given, In a ΔMRC and ΔWYC MR = 14, CR=28, WY = 6, and MW = 17.88.
Now, MR = 14 and MW = 17.88.
Therefore, (MW/MR) = 17.88/14 = 1.28.
So, If WY = 6, then WE = (1.28)(6) = 7.66.
Now, In the ΔWYC, WY = 6 and WE = 7.66.
Therefore from the Pythagoras's theorem,
WE² - WY² = YC².
YC² = (7.66)² - 6².
YC² = 22.68.
YC = 4.76.

A candle is 18 in. tall after burning for 3 hours. After 5 hours, it is 16.5 in. tall. Write a linear equation to model
the relationship between height h of the candle and time t. Predict how tall the candle will be after burning 8
hours.
a. h(t) = -0.75t + 20.25; 14.25 inches
b. h(t) = 0.75t + 15.75; 9.75 inches
c. h(t) = -0.75t + 15.75; 9.75 inches
d. h(t) = 0.75t + 20.25; 14.25 inches
Answers
Answer: To write a linear equation to model the relationship between the height h of the candle and time t, we need to find the slope and y-intercept of the line that represents this relationship.
The slope of the line is given by the rise over the run, or the change in the y-value (the height of the candle) over the change in the x-value (the time). We can calculate the slope by taking the difference in the height of the candle after 5 hours and 3 hours, and dividing it by the difference in the time:
slope = (16.5 - 18) / (5 - 3) = (-1.5) / (2) = -0.75
The y-intercept of the line is the point at which the line crosses the y-axis. This is the height of the candle when the time is 0. We can use the height of the candle after 3 hours as the y-intercept, since this is the height when the time is 3:
y-intercept = 18
We can use these values to write a linear equation in the form y = mx + b, where m is the slope and b is the y-intercept.
Plugging in the values we found, we get:
h(t) = -0.75t + 18
This is the linear equation that models the relationship between the height h of the candle and time t.
To predict how tall the candle will be after burning for 8 hours, we can plug in t = 8 into the equation:
h(8) = -0.75(8) + 18 = -6 + 18 = 12 inches
This means that the candle will be 12 inches tall after burning for 8 hours.
Therefore, the correct answer is (d) h(t) = 0.75t + 20.25; 14.25 inches.
To write a linear equation to model the relationship between the height of the candle and time, we can use the information given. We know that after 3 hours, the candle is 18 inches tall, and after 5 hours, it is 16.5 inches tall.
We can set up a system of linear equations to represent this information. Let's call the height of the candle h and the time t. Then we can set up the following system:
h = 18 - 3t
h = 16.5 - 5t
To solve this system, we can set the two equations equal to each other and solve for t:
18 - 3t = 16.5 - 5t
1.5 = 2t
t = 0.75
This tells us that the height of the candle decreases by 0.75 inches per hour.
Now we can use this information to predict how tall the candle will be after 8 hours. We can plug in 8 for t in the equation h = 18 - 3t to find the height of the candle:
h = 18 - 3(8)
h = 18 - 24
h = -6 inches
So the candle will be about 6 inches shorter after burning for 8 hours. This means it will be about 10.5 inches tall.
The correct option is c, h(t) = -0.75t + 15.75; 9.75 inches.
This is because we found that the height of the candle decreases by 0.75 inches per hour, which is represented by the coefficient of t in the equation. The y-intercept, 15.75, represents the initial height of the candle, which we found to be 16.5 inches.

Answers
The required value of "a" would be 3.
What are the perpendicular lines?Perpendicular lines are two lines that cross one other and create a 90-degree angle.
As per the question, we have
Line m has the equation y = −13x − 2
Here slope of line m = -13
The slope of the given line m will be -13,
Line k passes through the points (0,4) and (9, a).
The slope of line k = (a - 4)/(9-0)
The slope of line k = (a - 4)/9
Given line m and line k are both perpendicular to each other,
We know that two lines are perpendicular if the product of their slopes is -1.
So, -13 × (a - 4)/9 = -1
⇒ -13a + 52 = 13
⇒ 13a = 52 - 13
⇒ 13a = 39
⇒ a = 39/13
⇒ a = 3
Therefore, the required value of "a" would be 3.

5x5=25
••therefore your answer is 25
it’s basic algebra. it’s not calculus:)
Tanisha has 54 m of fencing to build a three-sided fence around a rectangular plot of land that sits on a riverbank. (The fourth side of the enclosure would be the river.)
'The area of the land is 280 square meters. List each set of possible dimensions (length and width) of the field.
Answers
13.5m × 20.74m or 20.74m × 13.5m can be the possible dimensions.
What are dimensions?Height, length, and width are the three dimensions that all of the places we dwell and things we utilize on a daily basis have.
Height, depth, and other dimensions are examples of dimensions.
The dimensions of a line, a square, and a cube are each one, two, and three, respectively.
However, we consider the Universe to have one temporal dimension and three spatial dimensions (north-south, east-west, and up-down).
So, we have the area (A):
A = (54 – 2x)x
A = 54x - 2x²
Differentiate to obtain: dA/dX = 54 - 4x
We shall differentiate and equate to zero for a maximum Area, so dA/dx = 0.
54 – 4x = 0
x = 54/4
x = 13.5 m
It covers 280 m². Consequently, the other potential dimension:
w = 280/13.5
w = 20.74 m
Therefore, 13.5m × 20.74m or 20.74m × 13.5m can be the possible dimensions.
