Peter had a sum of money. He gave his wife $1400 and spent $400 on a TV set. Then he gave 2/5 of the remaining money to his 3 children. Each child received 1/12 of the money, how much did each child receive?
Peter had no money left to give to his children and each child received $0.
Let's start by finding the amount of money Peter had initially:
Initial money = Money is given to wife + Money spent on TV + Remaining money
Initial money = $1400 + $400 + Remaining money
Initial money = $1800 + Remaining money
Next, we need to find the amount of money Peter had left after giving $1400 to his wife and spending $400 on a TV set:
Remaining money = Initial money - Money is given to wife - Money spent on TV
Remaining money = ($1800 + Remaining money) - $1400 - $400
Remaining money = $1800 + Remaining money - $1800
Remaining money = $0
This means that Peter spent all his money on his wife and the TV set, so he had no money left to give to his children.
Therefore, each child received $0.

1. A weather balloon that contains 540 m' of helium springs a leak and empties in 60 seconds. Suppose that the volume of helium in the balloon as a function of time is given by V(t)=540 (1-t÷60)^3 (a) the average rate of change of volume during the 60 seconds it takes to empty. (b) the volume of the balloon after 40 seconds. (c) the instantaneous rate of change of the volume at 40 seconds.
Answer:
(a) Average rate of change of volume during the 60 seconds it takes to empty: -9 m^3/s
(b) Volume of the balloon after 40 seconds: 270 m^3
(c) Instantaneous rate of change of volume at 40 seconds: -67.5 m^3/s
Step-by-step explanation:
(a) The average rate of change of volume during the 60 seconds it takes to empty can be calculated by finding the change in volume over the change in time:
Average rate of change = (V(60) - V(0)) / (60 - 0)
where V(60) is the volume of the balloon at 60 seconds and V(0) is the volume at 0 seconds. Substituting these values into the equation V(t) = 540(1 - t/60)^3, we get:
V(60) = 0
V(0) = 540
So, the average rate of change of volume is:
Average rate of change = (0 - 540) / (60 - 0) = -9 m^3/s
(b) The volume of the balloon after 40 seconds can be found by substituting t = 40 into the equation V(t) = 540(1 - t/60)^3:
V(40) = 540(1 - 40/60)^3 = 270 m^3
Therefore, the volume of the balloon after 40 seconds is 270 m^3.
(c) The instantaneous rate of change of volume at 40 seconds can be found by taking the derivative of the volume function with respect to time:
dV/dt = -540(3/60)(1 - t/60)^2
Substituting t = 40 into this equation, we get:
dV/dt | t=40 = -540(3/60)(1 - 40/60)^2 = -67.5 m^3/s
Therefore, the instantaneous rate of change of volume at 40 seconds is -67.5 m^3/s.

The SOLVE Process_ The Lamp Post Shadow. The Task: At a certain time of day, the length of the shadow of a 5-foot-tall lamp post was 8 feet. Part A. What is the angle of elevation from the top of the shadow of the lamppost to the top of the lamppost? Provide evidence, including a drawing, to support your answer. Part B What will be the length, to the nearest foot, from the top of the lamppost to the top of its shadow at a time of day when the angle of elevation is half of the current angle of elevation? Provide evidence, including a drawing, to support your answer.
The correct answer is : Part A: The angle of elevation from the top of the shadow to the top of the lamppost is 0 degrees.
Part B: The length from the top of the lamppost to the top of its shadow cannot be determined without knowing the value of [tex]\frac{\theta}{2}[/tex], the current angle of elevation.
Part A: To determine the angle of elevation from the top of the shadow to the top of the lamppost, we can use trigonometry. Let's denote the angle of elevation as θ.
In a right triangle, the tangent of an angle is equal to the ratio of the length of the opposite side to the length of the adjacent side. In this case, the opposite side is the height of the lamppost (5 feet), and the adjacent side is the length of the shadow (8 feet).
Using the tangent function:
[tex]\(\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} = \frac{5}{8}\)[/tex]
To find θ, we can take the inverse tangent (arctan) of both sides:
[tex]\(\theta = \arctan\left(\frac{5}{8}\right)\)[/tex]
The value of θ can be calculated using a scientific calculator or by referencing trigonometric tables.

Part B: To find the length from the top of the lamppost to the top of its shadow when the angle of elevation is half of the current angle (θ/2), we can use trigonometry again.

Using the tangent function again:
[tex]\(\tan\left(\frac{\theta}{2}\right) = \frac{\text{opposite}}{\text{adjacent}} = \frac{5}{x}\)[/tex]
Rearranging the equation to solve for x:
[tex]\(x = \frac{5}{\tan\left(\frac{\theta}{2}\right)}\)[/tex]
Substituting the value of θ from Part A:
[tex]\(x = \frac{5}{\tan\left(\frac{\arctan\left(\frac{5}{8}\right)}{2}\right)}\)[/tex]

Domain: x ∈ (- ∞, + ∞)Range: y ∈ [0, + ∞)Demand for a tie-dyed shirt is given by the formula
p = 5 + 100 / √q
where p is the price in dollars you can charge to sell q shirts per month. If you currently sell shirts for $10 each and you raise the price by $1 each month, how fast will the demand drop?
The demand will drop by 741 T-shirts per dollar increase in price.
How fast will the demand drop?We will use derivative of p formula with respect to q to find how fast the demand will drop [tex]dp/dq = -50/\sqrt{q^3}[/tex]
At the initial price of $10, the corresponding demand is:
p = 5 + 100/√q = 10
Solving for q, we get:
q = 10000/9
Now, we will find rate of change of demand as the price increases by differentiating the demand formula with respect to p:
[tex]\frac{dq}{dp} = -1/\frac{dp}{dq}[/tex]
At p = 10, we have:
dq/dp = -1/(-50/√(10000/9)^3)
dq/dp = -1/(-0.00135)
dq/dp = 740.740740741
dq/dp = 741.

4096/16 = 256
Now you multiply the powers on top with the power outside the parenthesis. So (r^-2t^3)^-3
so you now have r^6 t^-9
your equation looks like 256 r^6 t^-9/r^0
But you can't have negative numbers for your powers so we are going to add/subtract with the bottom of the fraction. There are no t's to add/subtract so the t's move to the bottom and become positive. the r has a 0 power so it goes away.

Why do firms earn positive profits in the short run?When the market price is between P4 and P6, firms in a competitive industry are able to earn positive profits in the short run because the price is above their average variable cost (AVC) but below their average total cost (ATC).
This means that firms are covering their variable costs and also making a contribution towards their fixed costs. As a result, they are earning positive profits. But, in the long run the firms will enter the industry and increase supply causing market price to decrease towards P4 where firms earn zero economic profits in the long run.

Natalie is admiring a statue in Campbell Park from 8 meters away. If the distance between the top of the statue to Natalie's head is 10 meters, how much taller is the statue than Natalie?
Natalie is 2 meters taller than the statue.
To solve this problem
Calculating the distance in height between Natalie's head and the statue's peak is necessary.
According to the information provided, Natalie is located 8 meters from the statue, and Natalie's head is 10 meters from the top of the monument.
With the aid of the comparable triangles idea, we can establish the ratio shown below:
(height of statue) / (distance to statue) = (height difference) / (distance to Natalie's head)
Let's denote the height of the statue as "H" and the height difference as "D." The proportion can be written as:
H / 8 = D / 10
To find the height difference (D), we can rearrange the equation:
D = (H / 8) * 10
Given that the distance between the top of the statue and Natalie's head is 10 meters, we can substitute this value into the equation:
10 = (H / 8) * 10
Dividing both sides by 10:
1 = H / 8
Multiplying both sides by 8:
H = 8
Therefore, the height of the statue is 8 meters.
We deduct Natalie's height (10 meters) from the statue's (8 meters) height to find the height gap between the two:
Height difference = Statue's height - Natalie's height
= 8 - 10
= -2
The negative value indicates that Natalie's height is 2 meters taller than the statue.
Therefore, Natalie is 2 meters taller than the statue.

The table below shows the amount of money Natalie still owes her parents at the end of every two weeks for the first eight weeks.
Number of Weeks Natalie Has Paid, Amount Natalie Still Owes,
0 $180.
2 $162.
4 $144.
6 $126.
8 $108.
How much does Natalie pay her parents each week per week, Write a function that shows the relationship between the amount Natalie still owes, and the number of weeks she has paid,
Answer:
The answer is as follows
Step-by-step explanation:
Natalie borrowed $180 from her parents. Over the course of 8 weeks, she paid back equal amounts every 2 weeks. We can find the amount she pays each week by finding the difference in the amount she owes between two consecutive weeks and dividing by 2.
For example, between week 0 and week 2, she paid back $180 - $162 = $18. Dividing by 2, we get $9 per week. Similarly, between week 2 and week 4, she paid back $162 - $144 = $18, so she pays $9 per week. We can do this for all the consecutive weeks to find the average amount she pays per week:
- Between week 0 and week 2: $9 per week
- Between week 2 and week 4: $9 per week
- Between week 4 and week 6: $9 per week
- Between week 6 and week 8: $9 per week
So Natalie pays her parents $9 per week.
To write a function that shows the relationship between the amount Natalie still owes and the number of weeks she has paid, we can use the formula:
Amount owed = $180 - $9 * (number of weeks paid)
or
Amount owed = $180 - $9x
where x is the number of weeks paid.
