Three ballet dancers are positioned on stage. Max is 2 feet straight behind Kenji and 4 feet directly left of Lindsey. When the music begins, Max twirls to Lindsey's position, then leaps to Kenji's position, and finally walks back to his original position. How far did Max travel? If necessary, round to the nearest tenth.
The total distance Max traveled is 8.2 feet which is found by adding three distances together gives us the total distance Max traveled.
What is distance?Distance can be measured using other units such as time, speed, or even angles.
To calculate this, we need to find the distance between Max's original position and Lindsey's position, the distance between Lindsey's position and Kenji's position, and the distance between Kenji's position and Max's original position.
The distance between Max's original position and Lindsey's position=
4.0 feet.
This is because Max was 4 feet to the left of Lindsey.
The distance between Lindsey's position and Kenji's position= 2.8 feet. This is because Kenji was 2 feet behind Lindsey and Max was 4 feet left of Lindsey.
The distance between Kenji's position and Max's original position= 1.4 feet.
This is because Kenji was 2 feet behind Max.
Adding these three distances together gives us the total distance Max traveled: 4.0 feet + 2.8 feet + 1.4 feet = 8.2 feet.

At the end of a party 25 people shook hands with each other. How many handshakes were there in total? (Please provide explanation)
Answer:
Hi
Please mark brainliest ❣️
Thanks
Step-by-step explanation:
Since 25 people shook hands
Therefore 25!
Which is 120
Answer:
To calculate the total number of handshakes, we can use the formula for the sum of the first n natural numbers.
The number of handshakes is equal to the sum of the first 24 natural numbers (excluding the individual's handshake with themselves) since each person shakes hands with every other person once.
The formula for the sum of the first n natural numbers is given by:
Sum = (n * (n + 1)) / 2
Applying this formula, we have:
Sum = (24 * (24 + 1)) / 2
= (24 * 25) / 2
= 600
Therefore, there were a total of 600 handshakes at the end of the party.

Answer:
(a) width = (x - 1)
length = (7x - 6)
(b) Area = 350 cm²
Perimeter = 114 cm
Step-by-step explanation:
Part (a)Given equation: \(7x^2-13x+6\)
⇒ a = 7, b = -13, c = 6
Find 2 two numbers that multiply to ac and sum to b: -6 and -7
Rewrite b as the sum of these 2 numbers:
\(\implies 7x^2-7x-6x+6\)
Factorize the first two terms and the last two terms separately:
\(\implies 7x(x-1)-6(x-1)\)
Factor out the common term (x - 1):
\(\implies (7x-6)(x-1)\)
Therefore:
width = (x - 1)length = (7x - 6)Part (b)Substitute the given value of x = 8 into the equations to find the area and perimeter:
\(\begin{aligned}x=8cm \implies \textsf{Area} & = 7(8)^2-13(8)+6\\& = 448-104+6\\& = 350 \sf \:\: cm^2\end{aligned}\)
\(\begin{aligned}\textsf{Perimeter} & = 2(\sf width+length)\\& =2[(x-1)+(7x-6)]\\ & = 2[(8-1)+(7(8)-6)]\\ & = 2[7+(56-6)] \\& = 2(7+50)\\& = 2(57)\\ & = 114 \sf \:\: cm\end{aligned}\)
Answer:
See below ~
Step-by-step explanation:
\(\textsf {Question 15(A) :}\)
\(\textsf {Given :}\)
\(\implies \mathsf {7x^{2} - 13x + 6}\)
\(\textsf {Splitting the middle term :}\)

\(\textsf {Dimensions are :}\)
\(\textsf {Length = (7x - 6)}\)\(\textsf {Width = (x - 1)}\)\(\textsf {Question 15(B) :}\)
\(\textsf {Formula for perimeter :}\)
\(\implies \mathsf {2 \times (length + width)}\)
\(\implies \mathsf {2 \times (7x - 6 + x - 1)}\)
\(\implies \mathsf {2 \times (8x-7)}\)
\(\textsf {Substitute x = 8 :}\)
\(\implies \mathsf {2 \times [8(8)-7]}\)
\(\implies \mathsf {2 \times (64-7)}\)
\(\implies \mathsf {2 \times 57}\)
\(\implies \mathsf {Perimeter = 114 cm}\)
\(\textsf {Now substitute x = 8 in the area formula :}\)
\(\implies \mathsf {7(8)^{2} - 13(8) + 6}\)

show that f(x)=5x-6 and f^-1(x) = x+6/5 are inverse funcrions using composition of functions
\(f(f^{-1}(x))=f \left(\frac{x+6}{5} \right)=5 \left(\frac{x+6}{5} \right)-6=x+6-6=x\\\\f^{-1}(f(x))=f^{-1}(5x-6)=\frac{5x-6+6}{5}=\frac{5x}{5}=x\)
Since \(f(f^{-1}(x))=f^{-1}(f(x))=x\), the functions are inverses of each other.
The composition of functions is x, f(x) and f⁻¹(x) are inverse functions.
What is inverse function?Inverse function is represented by f⁻¹ with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
The given functions are f(x)=5x-6 and f⁻¹(x)=(x+6)/5.
The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)).
Now, h(x)=f(f⁻¹(x))
h(x)=5((x+6)/5 -6)
h(x)=x+6-6
h(x)=x
Since, the composition of functions is x, f(x) and f⁻¹(x) are inverse functions.

Answer:
B. "R is 85% of the original cost."
Step-by-step explanation:
The given equation is P - 0.15P = R, where P is the original cost of the shirt and R is the discounted price that Brandon paid.
Simplifying the equation, we get:
0.85P = R
Dividing both sides by P, we get:
0.85 = R/P
Therefore, the discounted price R is 85% of the original cost P.
So, the answer is (B) "R is 85% of the original cost."

1. Lim f(x) as x approaches -infinity. To determine the value of lim f(x) as x approaches negative infinity, we need to look at the left end of the graph of f(x). lim f(x) as x approaches -infinity is equal to positive infinity or negative infinity, respectively. If the graph of f(x) oscillates between positive and negative infinity or does not approach any value, then the limit does not exist (DNE).
2. Lim f(x) as x approaches +infinity. To determine the value of lim f(x) as x approaches positive infinity, we need to look at the right end of the graph of f(x). If the graph of f(x) approaches a specific value, then lim f(x) as x approaches +infinity exists and is equal to that value. If the graph of f(x) approaches positive infinity or negative infinity, then lim f(x) as x approaches +infinity is equal to positive infinity or negative infinity, respectively. If the graph of f(x) oscillates between positive and negative infinity or does not approach any value, then the limit does not exist (DNE).
3. Lim f(x) as x approaches a specific value. For this case, we need to look at the behavior of the graph of f(x) as x approaches the specific value. If the graph of f(x) approaches a specific value, then lim f(x) as x approaches that value exists and is equal to that value. If the graph of f(x) approaches positive infinity or negative infinity, then lim f(x) as x approaches that value is equal to positive infinity or negative infinity, respectively. If the graph of f(x) oscillates between positive and negative infinity or does not approach any value, then the limit does not exist (DNE).

which equation has a graph with a slope of -7 and an x-intercept of -5?
Answer:
y= -7(x + 5)
Step-by-step explanation:
The equation of the graph with slope -7 and x- intercept -5 is
y = -7x -35.
What is slope intercept form?The slope intercept of a line is given by the equation y = m x+ c
y is y coordinate, x is x coordinate, m is the slope of the line
c is y- intercept of the line
c can also be found if a point on the line is given say (a, b) and slope is given .We put this point in the given slope intercept form and find c .
Let the slope and y -intercept form equation of the given lines be
y= mx+ b
where m is slope and b is y-intercept
given that slope =-7
∴ m = -7
Then equation becomes y = -7x +b
Given that x- intercept is -5, which means that the given graph intersects the x- axis at point (-5,0)
Substitute y =0 and x= -5 in equation y = -7x +b
⇒ 0 = -7(-5) +b
⇒0 = 35 +b
⇒-35 = b
∴ The y - intercept is -35
Thus, the equation of the given graph becomes y = -7x -35

For f(x) =2x, find a formula for the Riemann sum obtained by dividing the interval [2.5] subintervals and using the right hand endpoint for each ck. Simplify the sum and take the limit as n--> infinity to calculate the area under the curve over [2,5]
please show all of your work as be as descriptive as you can I appreciate your help thank you!
The area under the curve over [2,5] is 24.
Given function is f(x) = 2xIntervals [2, 5] is given and it is to be divided into subintervals.
Let us consider n subintervals. Therefore, width of each subinterval would be:
$$
\Delta x=\frac{b-a}{n}=\frac{5-2}{n}=\frac{3}{n}
$$Here, we are using right-hand end point. Therefore, the right-hand end points would be:$${ c }_{ k }=a+k\Delta x=2+k\cdot\frac{3}{n}=2+\frac{3k}{n}$$$$
\begin{aligned}
\therefore R &= \sum _{ k=1 }^{ n }{ f\left( { c }_{ k } \right) \Delta x } \\&=\sum _{ k=1 }^{ n }{ f\left( 2+\frac{3k}{n} \right) \cdot \frac{3}{n} }\\&=\sum _{ k=1 }^{ n }{ 2\cdot\left( 2+\frac{3k}{n} \right) \cdot \frac{3}{n} }\\&=\sum _{ k=1 }^{ n }{ \frac{12}{n}\cdot\left( 2+\frac{3k}{n} \right) }\\&=\sum _{ k=1 }^{ n }{ \frac{24}{n}+\frac{36k}{n^{ 2 }} }\\&=\frac{24}{n}\sum _{ k=1 }^{ n }{ 1 } +\frac{36}{n^{ 2 }}\sum _{ k=1 }^{ n }{ k } \\&= \frac{24n}{n}+\frac{36}{n^{ 2 }}\cdot\frac{n\left( n+1 \right)}{2}\\&= 24 + \frac{18\left( n+1 \right)}{n}
\end{aligned}
$$Take limit as n → ∞, so that $$
\begin{aligned}
A&=\lim _{ n\rightarrow \infty }{ R } \\&= \lim _{ n\rightarrow \infty }{ 24 + \frac{18\left( n+1 \right)}{n} } \\&= \boxed{24}

Given function f(x) = 2x. The interval is [2,5]. The number of subintervals, n is 3.
Therefore, the area under the curve over [2,5] is 21.
From the given data, we can see that the width of the interval is:
Δx = (5 - 2) / n
= 3/n
The endpoints of the subintervals are:
[2, 2 + Δx], [2 + Δx, 2 + 2Δx], [2 + 2Δx, 5]
Thus, the right endpoints of the subintervals are: 2 + Δx, 2 + 2Δx, 5
The formula for the Riemann sum is:
S = f(c1)Δx + f(c2)Δx + ... + f(cn)Δx
Here, we have to find a formula for the Riemann sum obtained by dividing the interval [2.5] subintervals and using the right hand endpoint for each ck. The width of each subinterval is:
Δx = (5 - 2) / n
= 3/n
Therefore,
Δx = 3/3
= 1
So, the subintervals are: [2, 3], [3, 4], [4, 5]
The right endpoints are:3, 4, 5. The formula for the Riemann sum is:
S = f(c1)Δx + f(c2)Δx + ... + f(cn)Δx
Here, Δx is 1, f(x) is 2x
∴ f(c1) = 2(3)
= 6,
f(c2) = 2(4)
= 8, and
f(c3) = 2(5)
= 10
∴ S = f(c1)Δx + f(c2)Δx + f(c3)Δx
= 6(1) + 8(1) + 10(1)
= 6 + 8 + 10
= 24
Therefore, the Riemann sum is 24.
To calculate the area under the curve over [2, 5], we take the limit of the Riemann sum as n → ∞.
∴ Area = ∫2^5f(x)dx
= ∫2^52xdx
= [x^2]2^5
= 25 - 4
= 21
Therefore, the area under the curve over [2,5] is 21.
