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
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?
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

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

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

100 POINTS!!! Find the exact length of side a.
Has to be one of the four options
Answer: a = 2√3
First method (Pythagoras theorem):
a² + b² = c²
a² + 2² = 4²
a² = 16 - 4
a = √12
a = 2√3
Second method (sine rule):
opposite/hypotenuse = sin(x)
a/4 = sin(60)
a = 4sin(60)
a = 2√3
Third method (tan rule):
opposite/adjacent = tan(x)
a/2 = tan(60)
a = 2tan(60)
a = 2√3
Answer:
2√3
Step-by-step explanation:
From inspection of the given triangle:
Side a is opposite angle A ⇒ a = BCSide b is opposite angle B ⇒ b = ACSide c is opposite angle C ⇒ c = ABAs we cannot be sure that ΔABC is a right triangle since it is not marked as such, use the cosine rule to find the exact length of side a.
Cosine Rule
[tex]a^2=b^2+c^2-2bc \cos A[/tex]
where a, b and c are the sides and A is the angle opposite side a
Given:
A = 60°b = 2c = 4Substitute the given values into the formula and solve for a:
[tex]\implies a^2=2^2+4^2-2(2)(4) \cos 60^{\circ}[/tex]
[tex]\implies a^2=4+16-16\left(\dfrac{1}{2}\right)[/tex]
[tex]\implies a^2=20-8[/tex]
[tex]\implies a^2=12[/tex]
[tex]\implies a=\sqrt{12}[/tex]
[tex]\implies a=\sqrt{4 \cdot 3}[/tex]
[tex]\implies a=\sqrt{4}{\sqrt{3}[/tex]
[tex]\implies a=2\sqrt{3}[/tex]
Therefore, the exact length of side a is 2√3.
To find out if ΔABC is a right triangle, use Pythagoras Theorem to solve for side a:
[tex]\implies a^2+b^2=c^2[/tex]
[tex]\implies a^2+2^2=4^2[/tex]
[tex]\implies a^2+4=16[/tex]
[tex]\implies a^2=12[/tex]
[tex]\implies a=\sqrt{12}[/tex]
[tex]\implies a=2\sqrt{3}[/tex]
As the measure of side a is the same as the solution found when using the cosine rule, we can conclude that ΔABC is a right triangle.

4cos(-5B) sin3B is equivalent to
The trigonometric identity 4cos(-5B) sin3B is equivalent to 2[sin(8B) - sin(2B)]
How to find the trigonometric identity 4cos(-5B) sin3B is equivalent to?Since we have 4cos(-5B) sin3B
Using the trigonometric identity
sin(x + y) - sin(x - y) = 2cosxsiny
So, cosxsiny = [sin(x + y) - sin(x - y)]/2
Since we have 4cos(-5B) sin3B, comparing cos(-5B) sin3B with cosxsiny, we have
x = -5B and y = 3B
So, we have cos(-5B)sin3B = [sin(-5B + 3B) - sin(-5B - 3B)]/2
= [sin(-2B) - sin(-8B)]/2
= [-sin(2B) - {-sin(8B)}]/2 [since sin(-2B) = -sin(2B)]
= [-sin(2B) + sin(8B)]/2
= [sin(8B) - sin(2B)]/2
So, 4cos(-5B)sin3B = 4 × [sin(8B) - sin(2B)]/2
= 2[sin(8B) - sin(2B)]
So, the trigonometric identity 4cos(-5B) sin3B is equivalent to 2[sin(8B) - sin(2B)]

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?
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
