Answer: $795.70.
Step-by-step explanation: To calculate the amount of interest that Ayana will earn in 3 years, we need to first determine the annual interest rate. If the interest rate is 3% compounded annually, then the annual interest rate is 0.03.
Next, we need to calculate the total amount of interest that Ayana will earn over the 3 year period. To do this, we can use the formula for compound interest: A = P(1 + r/n)^nt, where A is the total amount of interest earned, P is the principal (initial amount of money in the account), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time in years.
In this case, P = $730, r = 0.03, n = 1 (since the interest is compounded annually), and t = 3. Plugging these values into the formula, we get:
A = $730(1 + 0.03/1)^1*3 = $730(1.03)^3 = $730 * 1.09 = $795.70
Therefore, Ayana will earn $795.70 in total interest over the 3 year period. To the nearest cent, this is $795.70.

v. In what year will the population of the town be 14,700?
Year:
Answer:
i. P = -800t + 29900
ii. as an inequality: 0≤t≤37.375; interval notation: [0,37.375]
iii. as an inequality: 0≥P≥29900; interval notation: [0,29900]
iv. the population decreases at a rate of 1600 people every 3 years
v. 2010
Step-by-step explanation:
i. a) use the points *(4,26700) and **(12,20300) to find the slope (m)
*: the year 1995(4 years after 1991) and the population that year
**: the year 2003(12 years after 1991) and the population that year
m = (20300-26700)/(12-4) = -6400/8 = -800
b) use one of the points and m in (a) to find b
26700 = -800(4) + b
26700 = -3200 + b
29900 = b
ii. starting value for domain will be 0 since 1991 is year 0. Find the ending domain value by using P=0 and solving the equation for t:
0 = -800t + 29900
800t = 29900
t = 37.375
iii. population starts at a high of 29900 people and can't go lower than 0 people.
iv. the slope is given in (population change) / (number of years)
v. make P=14700 and solve the equation for t
14700 = -800t + 29900
800t = 15200
t = 19 (19 years after 1991)

The sum of two numbers is always greater than the larger of the two numbers?
False
Step-by-step explanation:The sum is the total of an addition problem.
Addition of Positive Numbers
Most commonly, people add together positive numbers. Positive numbers are numbers greater than 0. The sum of 2 positive numbers is always greater than the addends. For example:
2 + 3 = 5The sum of these positive numbers, 5, is greater than the larger number, 3. However, the addition of positive numbers is not the only way to add.
Addition of Negative Numbers
Negative numbers are numbers less than 0. If you add negative numbers, then the sum will be less than the addends. So, the statement above is not true. For example:
-2 + 3 = 1In this case, the sum, 1, is less than the larger number, 3. This disproves the statement given.

You’re planning to visit with 7 clients today and you estimate that at most each client will require 3/4 hours of your time. At most, how long does your estimate say it will take you to visit with all of these clients?
Mathematically, it will take you 315 minutes (5 hours, 15 minutes) at most to visit with all 7 clients.
How is the time determined?We can employ mathematical operations, including addition, subtraction, division, and multiplication to determine the total time required to visit the seven clients.
Since we know that a client requires 3/4 hours or 45 minutes of your visiting time, we can multiply 45 minutes by 7.
The product of the multiplication operation gives 315 minutes, which we can convert into hours and minutes by a division operation.
The number of clients visiting today = 7
The time it a client requires of your visit time = 3/4 hours
3/4 hours = 45 minutes (0.75 x 60)
For the 7 clients, it will take you 315 minutes (45 x 7)
315 minutes equal 5 hours and 15 minutes.
Thus, using basic mathematical operations, we can conclude that, at most, you require 5 hours and 15 minutes to attend to all seven clients today.

Function A is represented by the equation y=2 x+5
Function B is a linear function that goes through the points shown in the table.
Which statement correctly compares the rates of change of the two functions?
Answer:
The rate of change is the same for both A and B (2)
Step-by-step explanation:
In the equation, the rate of change is shown as the coefficient of the variable x. That is the number before the x which is 2.
In the table you find the rate of change as the change in y over the change in x. In the table the y's are increasing by 4 (3- -1), 2 (5-3) and 4 (9-5). The x's are increasing by 2 (3-1), 1 (4-3) and 2 (6-4).
If I take the change in y over the change in x, I will get 4/2 = 2, 2/1 = 2 or 4/2 = 2
From the table the rate of change is also 2.

:On hand she has a 20% acid solution and a 50% acid solution. How many ml of each solution should sheStep-by-step explanation:this is the answer
A chemist needs 40mL of 20% acidic solution and 60mL of 50% acidic solution.
What is percentage?The percentage is the ratio of number expressed as a fraction of 100.
Assume chemist needs x mL of 20% of acidic solution and y mL of 50% acidic solution.
A total of 100mL solution is to be created.
x+y=100
x=100-y
The concentration of 20% acidic solution will be 0.2x, concentration of 50% acidic solution will be 0.5x and the sum of their concentrations should be 0.38(100).
0.2x+0.5y=0.38(100)
0.2x+0.5y=38
Substitute x=100-y into the obtained equation.
0.2(100-y)+0.5y=38
20-0.2y+0.5y=38
20+0.3y=38
0.3y=18
y=18/0.3
y=60
Substitute y=60 into x=100-y.
x=100-60
=40
So, the chemist needs 40mL of 20% acidic solution and 60mL of 50% acidic solution.
