What is the average rate of change of the function on the interval from x = 3 to x = 5?
f(x)=10(2)x
Answer: 1560
Step-by-step explanation: The average rate of change of a function over an interval is the total change in the value of the function divided by the length of the interval. In this case, the function is f(x) = 10(2)^x and the interval is [3, 5].
To find the average rate of change of the function over the interval, we can first evaluate the function at the two endpoints of the interval, which are x = 3 and x = 5. At x = 3, the function has a value of f(3) = 10(2)^3 = 80. At x = 5, the function has a value of f(5) = 10(2)^5 = 3200.
The total change in the value of the function over the interval is then the difference between the values at the two endpoints, which is f(5) - f(3) = 3200 - 80 = 3120.
The length of the interval is 5 - 3 = 2, since it goes from x = 3 to x = 5. Therefore, the average rate of change of the function over the interval is the total change in the value of the function divided by the length of the interval, which is (3120) / 2 = 1560.
Therefore, the average rate of change of the function f(x) = 10(2)^x on the interval [3, 5] is 1560.
Find the Banzhaf power distribution of the weighted voting system
[30: 17,15,13,1]
Give each player's power as a fraction or decimal value
p₁ ____
p₂ ____
p₃ ____

These are the possible combination of winning players:
{P1, P2}( weight :32) {P1, P2, P4} (weight: 31)
{P1, P2, P3} (weight: 45) {P1, P2, P3, P4} (weight: 46)
{P1, P3, P4} (weight: 31) {P1, P3} (weight: 30)
What is the distribution?
The mathematical expression known as a distribution function expresses the likelihood that a system would adopt a certain value or range of values. The traditional examples include games of chance.
The voting system tells us that the quota is 30, that Player 1 has 17 votes (or equivalently, has a weight of 17), Player 2 has 15 votes, Player 3 has 13 votes, and Player 4 has 1 votes.
A coalition is any group of one or more players. What we're looking for is winning coalitions - coalitions whose combined votes (weights) add to up to the quota or more. So the coalition {P3, P4} is not a winning coalition because the combined weight is 13 + 1 = 14, which is below the quota.
So we look at each possible combination of players and identify the winning ones:
{P1, P2}( weight :32) {P1, P2, P4} (weight: 31)
{P1, P2, P3} (weight: 45) {P1, P2, P3, P4} (weight: 46)
{P1, P3, P4} (weight: 31) {P1, P3} (weight: 30)
Hence, these are the possible combination of winning players.

Rania redesigned the bottom of one of the Landing pools. the equation that describes the bottom of the redesigned pool is y = 2/5x -60 in this equation y represents the depth of the water and x is the distance a guest lands away from the far wall all measurements are in inches. How deep is the water in the pool where a guest lands in the water 36 inches from the wall?
A. Y=74.4 in
B. Y=38.4 in
C. Y=45.6 in
D. Y=60 in
Answer:
C. y = 45.6 in
Step-by-step explanation:
Given equation:
[tex]y=\dfrac{2}{5}x-60[/tex]
where:
y is the depth of the water (in inches).x is the distance a guest lands away from the far wall (in inches).If a guest lands 36 inches from the wall, then x = 36.
Substitute x = 36 into the equation:
[tex]\implies y=\dfrac{2}{5}(36)-60[/tex]
[tex]\implies y=\dfrac{2 \cdot 36}{5}-60[/tex]
[tex]\implies y=\dfrac{72}{5}-60[/tex]
[tex]\implies y=14.4-60[/tex]
[tex]\implies y=-45.6[/tex]
Therefore, the depth of the water is 45.6 inches (since -45.6 inches means it is that distance below the surface).
Gayla Ojeda is trying to decide which of two different kinds of candy to sell in her retail candy store. One type is a name-brand candy that will practically sell itself. The other candy is cheaper to purchase but does not carry an identifiable brand name. Ms. Ojeda believes that she will have to incur significant advertising costs to sell this candy. Several cost items for the two types of candy are as follows: Brandless Candy Name-Brand Candy Cost per box $ 4.00 Cost per box $ 6.00 Sales commissions per box 1.00 Sales commissions per box 1.00 Rent of display space 900.00 Rent of display space 900.00 Advertising 3,000.00 Advertising 2,000.00
Required Identify each cost as being relevant or irrelevant to Ms. Ojeda’s decision and indicate whether it is fixed or variable relative to the number of boxes sold.
The costs as being relevant to Mrs. Ojeda's decision are Rent of display space 900.000 advertisement 3000 and irrelevant costs are commission,
How to determine relevant costsWe should know that the cost that differs from other costs in terms of alternative decision is called relevant cost, the irrelevant cost does not change as the result of a management decision.
Sales commission by brand 1.00 ........ Irrelevant to number of boxes
Rent of display space =900.000 ............ Relevant to number of boxes
Advertising cost = 3,000.00........................ Relevant to number of boxes
Cost per unit = 6.00 .................................. irrelevant to number of boxes

Function f is an exponential function
By what factor does the output value increase as each input value increases by 1?
Answer:
4
Step-by-step explanation:
You are given a table of function values in which x increases by 2, and you want to know the factor by which f(x) increases when x increases by 1.
FactorLet k represent the factor by which f(x) increases when x increases by 1. This means ...
f(2) = k·f(1)
f(3) = k·f(2) = k·(k·f(1)) = k²·f(1)
64 = k²·4
k² = 64/4 = 16
k = √16 = 4
The output value increases by a factor of 4 as the input value increases by 1.
__
Additional comment
The table values would also be obtained if the factor of increase were -4. That is, f(x) = -(-4)^x would give the same table. In that case, f(x) would not be a continuous function.

Factory XYZ has already produced 280 units today. The factory produces 92 units per hour. Today's goal is to produce at least
1,108 units. If x represents the number of production hours, which of the following inequalities symbolizes this situation?
The inequlity according to the given statement will be equal to 280 + 92(x) ≥ 1,108.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the given information in the question,
Rate of production per hour by the factory = 92 per hour
The factory has to produce at least 1,108 units.
Number of units produced today = 280
Assume x is the number of production hours,
Then, the equation will be,

n(t)=8300(1)

(c) After how many hours will the number of bacteria double? (Round your answer to one decimal place.)

Using an exponential function, the rate of growth is 20.482%, the number of bacteria after two hours is 12048.21 and the doubling time of the bacteria is 3.7 hours
Exponential FunctionExponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function.
A) The rate of growth can be calculated as
Data;
P = 8300A = 10000r = ?x = 1 hourWriting this in an exponential function;
A = P(1 + r)ˣ
10000 = 8300(1 + r)¹
r = 0.2048
r = 20.482%
B)
Substituting the values into the function above
x = 2
A = 8300(1 + 0.2048)²
A = 12048.21
C)
For the bacterial to double, the time will be
2 = (1 + 0.2048)ˣ

1 nickel = 5 cents
2 dimes = 20 cents
1 penny = 1 cent
The required coins that Ajit has are 1 quarter, 1 nickel, 2 dimes, and 1 penny.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Let,
Quarter = x
Nickle = y
Dimes = z
penny = a
So, accoding to the quesiton
0.25x + 0.5y + 0.10z + 0.01a = $0.51
Ajit has 5 coins in total
So that the sum of x + y + z + a = 5
Apply hit and trial,
1 quarter = 25 cents
1 nickel = 5 cents
2 dimes = 20 cents
1 penny = 1 cent
Total coins value = $0.51
