amelia started with $54, and spent $6 each day at camp. she has $18 left.write and solve an equation that can be used to find in how many days, d she has left at camp.which equation can be used to determine how many days d she was at camp?
Answers
Amelia was at camp for 6 days. The equation used to determine how many days(D) she was at camp is C x D = 6D and S - (C x D) = E
Given data:
S = initial amount = $54
D = the number of days
C = the cost per day = $6
E: the ending amount = $18
Amelia started with S=$54 and spent C=$6 each day at camp.
Therefore, the total amount she spent at camp is given in an algebraic expression that states the product of two variables:
C x D = 6D
Next, she ended with E=$18. So, the equation can be written in algebraic expression that states the difference between the variable:
S - (C x D) = E
Substituting the values in the equation we get:
54 - 6D = 18
54 - 18 = 6D
36 = 6D
D = 6
Therefore, Amelia was at camp for 6 days.

SOLUTION
From the question, the r is increasing at the rate of 6.4 feet per seconds.
This means that the equation of the radius is
\(r=6.4\times t\)So the function for the radius, in terms of t becomes
\(r(t)=6.4t\)The Area A is given as
\(A=\pi r^2\)So, the function for the area in terms of r becomes
\(A(r)=\pi r^2\)Now, (A . r)t becomes
\(\begin{gathered} (A.r)t=\pi r^2,\text{ where r\lparen t\rparen = 6.4t, we have } \\ (A.r)t=\pi\times(6.4t)^2 \\ =40.96\pi t^2 \end{gathered}\)Hence the answer is

Problem 2: Find a general solution for the following recurrence equation: Qn-1 +5Qn-2+3Qn-3+3". Show your work, clearly marking all steps of the solution. Hint: The characteristic polynomial factors into (x + 1)(x - 3).
Answers
The general solution of the given recurrence equation is Qn = (-1/4)(-1)n + (1/4)n(-1)n + (1/2)(3)n.
The given recurrence equation is
Qn-1 + 5Qn-2 + 3Qn-3 = 3
Let's find the characteristic equation of the given recurrence equation:
By assuming Qn = rn,
the characteristic equation can be derived as:
r3 - r2 - 5r - 3 = 0
So, the characteristic polynomial is
(r + 1)(r - 3)2
Let α = -1 and β = 3 (repeated roots)
Now, the solution of the given recurrence equation is:
Qn = Arn + Bnαn + Cnβn
As α = -1 and β = 3 are the roots of the characteristic equation, substitute these values in the above equation.
We have
A(-1)n + Bn(-1)n + Cn(3)n ... (1)
As we are going to find the general solution of Qn, the constants A, B, and C need to be determined.
Let's solve for A, B, and C by considering the first few terms of the given recurrence equation.
Suppose n = 3 in the recurrence equation Qn-1 + 5Qn-2 + 3Qn-3 = 3, we have
Q2 + 5Q1 + 3Q0 = 3 ... (2)
Now, substitute n = 2 in the general solution (1), we have
Q2 = A(-1)2 + B2(-1)2 + C23 ... (3)
Now, substitute n = 1 in the general solution (1), we have
Q1 = A(-1)1 + B1(-1)1 + C31 ... (4)
Now, substitute n = 0 in the general solution (1), we have
Q0 = A(-1)0 + B0(-1)0 + C30 ... (5)
Now, let's solve for A, B, and C using equations (2), (3), (4), and (5).
Q2 + 5Q1 + 3Q0 = 3:
2A + 5B + 3C = 3A(-1)2 + B2(-1)2 + C23:
A - B + 9C = 3A(-1)1 + B1(-1)1 + C31:
-A - B + 3C = 1A(-1)0 + B0(-1)0 + C30:
A + B + C = 1
On solving the above equations,
we get A = -1/4, B = 1/4, and C = 1/2
So, the general solution of the given recurrence equation is
Qn = (-1/4)(-1)n + (1/4)n(-1)n + (1/2)(3)n

Suppose Q and R are independent events. Find P(Q and R). P(Q)=0.37,P(R)=0.24
Answers
To find P(Q and R), we can use the formula: P(Q and R) = P(Q) × P(R) Since the events Q and R are independent, we can multiply the probabilities of each event to find the probability of both events occurring together. P(Q) = 0.37P(R) = 0.24P(Q and R) = P(Q) × P(R) = 0.37 × 0.24 = 0.0888.
Therefore, the probability of both Q and R occurring together is 0.0888. Long Answer:Independent events:In probability theory, two events are independent if the occurrence of one does not affect the probability of the occurrence of the other. Two events A and B are independent if the probability of A and B occurring together is equal to the product of the probabilities of A and B occurring separately. Mathematically,P(A and B) = P(A) × P(B) Suppose Q and R are independent events. Find P(Q and R).
We can use the formula: P(Q and R) = P(Q) × P(R) Since the events Q and R are independent, we can multiply the probabilities of each event to find the probability of both events occurring together. P(Q) = 0.37P
(R) = 0.24
P(Q and R) = P(Q) × P(R)
= 0.37 × 0.24
= 0.0888
Therefore, the probability of both Q and R occurring together is 0.0888. Hence, P(Q and R) = 0.0888. In probability theory, independent events are the events that are not dependent on each other. It means the probability of one event occurring does not affect the probability of the other event occurring.

find the taylor series for f centered at 5 if f(n)(5) = e5 14 for all n.
Answers
The Taylor series for the function f centered at 5 is given by f(x) = \(e^5\) + (x - 5)\(e^5\) + (1/2!)\((x - 5)^2\)\(e^5\) + (1/3!)\((x - 5)^3\)\(e^5\) + ...
The Taylor series expansion of a function f(x) centered at a point a is given by the formula:
f(x) = f(a) + f'(a)(x - a) + (1/2!)f''(a)\((x - a)^2\) + (1/3!)f'''(a)\((x - a)^3\) + ...
In this case, we are given that f(n)(5) = \(e^5\) * 14 for all n. This implies that all the derivatives of f at x = 5 are equal to \(e^5\) * 14.
Therefore, the Taylor series for f centered at 5 can be written as:
f(x) = f(5) + f'(5)(x - 5) + (1/2!)f''(5)\((x - 5)^2\) + (1/3!)f'''(5)\((x - 5)^2\) + ...
Substituting the given values, we have:
f(x) = \(e^5\) * 14 + (x - 5)\(e^5\) * 14 + (1/2!)\((x - 5)^2\)\(e^5\) * 14 + (1/3!)\((x - 5)^3\)\(e^5\) * 14 + ...

Answers
Answer:
A) The percent increase is by 30%.
B) for the original price = 15%.
B2.0) for the existing price (39) = approximately 11.54%.
Step-by-step explanation:
A) First, we divide 30 by 100. The result is the amount that 1% would be(0.3). If you multiply it by 30(which will become 30%) it will be 9. And from 30-39 is 9.
B) First we divide 30 by 100. The result is the amount that 1% would be(0.39). then if you multiply it by 11.54(which will become 11.54%) it will be 4.50(approximately because it actually is 4.5006 and there is no amount that ends up in 4.50). But if you are asking what percentage from the original cost(30) it would be 15% of it(because 0.3 * 15 = 4.50).

Answers
Answer:
79 people can only be in this so we have 53 kids so 53 * 4 = 212
Step-by-step explanation:
However, there is 53 kids to find how many adults you will have to do 79 - 53 which that = 26 so 26 adults were there. so 26 * 8.50 = 221.
To fine how much money they earn you will just have to add them up so
$212 + $ 221 = $433 so they didn't really earn the amount of money they really want which is $ 460.
Thus the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses is 29 tickets.

How to find the number of items from a total cost where each item cost is the same?We will divide the total cost by the cost of each item.
Example:
Cost of each item = $3
Total cost = $9
Number of items = $9 / $3 = 2
We have,
Student ticket:
Cost of each ticket = $4
Number of tickets sold = 53
Total sell from student tickets sold = 53 x $4 = $212
Adult ticket:
Cost of each ticket = $8.50
Number of adult tickets sold = M
Total sell of adult tickets sold = M x $8.50
Total number of people the auditorium can hold = 79
Minimum amount to make from ticket sales = $460
The remaining amount that needs to sale from adult tickets:
= $460 - $212
= $248
The number of adult tickets sold:
M = $248 / $8.50 = 29

Given that the radius is 40 cm
Circumference = 2π(40) = 80π cm
Find the distance traveled in 20 mins
Speed = 66 km/h
1 hour = 66 km
Rewrite hour into min
60 min = 66 km
1 min = 66 ÷ 60 = 1.1 km
Rewrite km in cm
1.1 km = 1.1 x 10,000 cm = 110,000 cm
Find the number of revolutions in 20 mins:
1 revolution = 80π cm
Number of revolution = 110,000 ÷ 80π = 437.5
