4.) b) 1/11^4
Explanation:
3. The axis of the symmetry is the straight line that divides the parabola into half.
Note down: the image below which shows a parabola (red line) and axis of symmetry (blue line).
4. Formula's: [tex]a^{-1} = \dfrac{1}{a}[/tex] , same with [tex]a^{-4 } = \dfrac{1}{a^4}[/tex]
So here: [tex]11^{-4}[/tex] is equivalent to [tex]\dfrac{1}{11^4}[/tex] which later equals to [tex]\dfrac{1}{14641}[/tex]

If the number of types of massages is represented by 4x + 3 and the number of
types of manicures is represented by -6x + 5 and the number of types of pedicures
is represented by 8x - 7, what is the expression for the total number of services they
have to choose from?
Answers
The expression for the total number of services the have to choose from is 6x - 1
Simplifying an expressionFrom the question, we are to determine the expression for the total number of services
From the given information,
Number of types of massages = 4x + 3
Number of types of manicures = -6x + 5
Number of types of pedicures = 8x - 7
Then,
Total number of services = 4x + 3 + (-6x + 5) + 8x - 7
Total number of services = 4x + 3 - 6x + 5 + 8x - 7
Total number of services = 4x - 6x + 8x - 7 + 3 + 5
Total number of services = 6x - 1
Hence, the expression for the total number of services the have to choose from is 6x - 1

The owner of a coffee shop chain creates a graph representing sales in thousands of dollars. She describes the characteristics as follows:
• There have been two turning points in sales this year.
• Sales are expected to increase in the long run.
• The least amount of sales during the year is about $250,000.
Which graph correctly shows the coffee shop’s sales?
Answers
Answer:
Step-by-step explanation:
So given the three bits of information you can conclude a couple of things. The end behavior towards the right should be increasing and since there is only two turning points this means it was previously going down but had a turning point and starting going up, and before that it was going up and then started going down, those will be the two turning points. So on the left side it should be decreasing and the right side it should be increasing. The last peace of information tells you that at the second turning point, should be equal to 250k when it turned back up OR the y-intercept is 250k. Given all this information the answer should be the first graph in the first picture

You start your working career when you are 24 years old. Each month, you deposit $144 into a pension plan. You continue making deposits into the plan you are 68 years old. What is the balance, in dollars, when the plan earns 6%, compounded monthlyRound your answer to the nearest cent
Answers
The balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is $372,134.19.
What is future value?The future value refers to the compounded future value of an asset, for example, a pension plan, based on a growth rate of interest for a future period.
The future value can be determined with the FV formula, table, or using an online finance calculator as follows:
Data and Calculations:N (# of periods) = 528 months (68 - 24 x 12 months)
I/Y (Interest per year) = 6%
PV (Present Value) = $0
PMT (Periodic Payment) = $144
Results:
FV = $372,134.19
Sum of all periodic payments = $76,032 ($144 x 528)
Total Interest = $296,102.19
Thus, the balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is $372,134.19.

In investing $6,150 of a couple's money, a financial planner put some of it into a savings account paying 6% annual simple interest. The rest was invested in a riskier mini-mall development plan paying 9% annual simple interest. The combined interest earned for the first year was $477. How much money was invested at each rate?
Answers
Answer:
3200
Step-by-step explanation:
0.13x + 0.04*(6100-x) = 532 dollars.
0.13x + 0.04*6100 - 0.04x = 532
(0.13 - 0.04)x = 532 - 0.04*6100
x = 532 - 0.04 - 6100/0.13-0.04 = 3200
The couple invested:
$2550 in savings account at 6% simple interest annually, and$3600 in development plan at 9% simple interest annually,to earn $477 as the total interest for the first year.
What is interest over an investment?The interest over an investment is the additional amount that a person receives on investing his/her money in the cause.
How to solve the question?In the question, we are informed that in investing $6,150 of a couple's money, a financial planner put some of it into a savings account paying 6% annual simple interest. The rest was invested in a riskier mini-mall development plan paying 9% annual simple interest. The combined interest earned for the first year was $477.
We are asked to find the amount invested in each rate.
We assume the amount invested in savings account to be $x.
Therefore, the amount invested in development plan is $(6150 - x).
Simple interest on a sum of money (P), at a rate (r) over a time period (t), is given as S.I. = (Prt)/100.
We calculate the interest earned in both investments:-
Investment in savings account:
Amount invested (P) = $x.
Rate of interest (r) = 6%.
Time for investment (t) = 1 year.
Therefore, interest received = (Prt)/100 = $(x*6*1)/100 = $ (6x)/100
Investment in development plan:
Amount invested (P) = $(6150 - x).
Rate of interest (r) = 9%.
Time for investment (t) = 1 year.
Therefore, interest received = (Prt)/100 = $((6150 - x)*9*1)/100 = $ {9(6150 - x)}/100.
We know that the total interest received is $477.
Thus on adding Interests from both the investments, we can write an equation:
(6x)/100 + {9(6150 - x)}/100 = 477
or, 6x + 55350 - 9x = 47700,
or, 55350 - 47700 = 3x,
or, 3x = 7650,
or x = 7650/3 = 2550.
Thus, the investments in:
Savings account = $x = $2550.Development plan = $(6150 - x) = $(6150 - 2550) = $3600.Learn more about simple interests at

Answers
The production quantity of 40,000 units, it is estimated that 38,000 units will be sold and 2,000 units will be salvaged. For the production quantity of 80,000 units, it is estimated that 64,000 units will be sold and 16,000 units will be salvaged.
Based on the information provided, let's analyze the production quantities of 40,000 units and 80,000 units, considering the assumptions for product sales and salvage.
40,000 unit plan:
Sold: 95% of 40,000 units = 0.95 * 40,000 = 38,000 units
Salvaged: 5% of 40,000 units = 0.05 * 40,000 = 2,000 units
80,000 unit plan:
Sold: 80% of 80,000 units = 0.80 * 80,000 = 64,000 units
Salvaged: 20% of 80,000 units = 0.20 * 80,000 = 16,000 units
Therefore, for the production quantity of 40,000 units, it is estimated that 38,000 units will be sold and 2,000 units will be salvaged.

Given the situation, which inequality models the number of additional weeks marie needs to continue saving to afford the home repairs? select the correct answer.
Answers
In the inequality models, the number of additional weeks is 1558+60x≥2158.
Given that the initial savings is $1558, the amount needed is $2158 and additional savings is $60 weekly.
Let the number of weeks be x.
So, she will save 60x in x weeks.
Total savings after x weeks is
Initial saving +60x .......(1)
According to the question, she needs $1258 for repair.
So, that means the minimum requirement is 2158.
≥2158 ........(2)
Combine equations (1) and (2) and get
Initial savings +60x≥2158
As given that the initial savings is 1558.
Substitute this in above inequality and get
1558+60x≥2158
To find the number of weeks find value of x.
Subtract 1558 from either sides of the inequality.
1558+60x-1558≥2158-1558
60x≥600
Divide both sides with 60 as
60x÷60≥600÷60
x≥10
Hence, the inequality that models the number of additional weeks marie needs to continue saving to afford the home repairs is 1558+60x≥2158 and she needs to save $60 for at least 10 weeks.
