First rewrite y - 2x 2 = 8 x + 5 as

y = 2x 2 + 8 x + 5

Complete square and determine vertex.

y = 2(x 2 + 4x + 4) - 8 + 5

Since it's asking for the left-endpoint Riemann Sum, you will only be using the top left point as the height for each of your four boxes, making -1, -2.5, -1.5, and -0.5 your heights. The bases are all the same length of 2. You don't include f(8) because you're not using right-endpoints, and that would also add another 5th box that isn't included in the 0 to 8 range.

Amy owns a graphic design store. She purchases a new printer to use in her store.
The printer depreciates by a fixed rate of 14% per year. The function
V = 2,400(1 – 0.14)t can be used to model the value of the printer in dollars after
t years.

Question:

Part A: Explain what the parameter 2,400 represents in the equation of the function.
Part B: What is the factor by which the printer depreciates each year?
Part C: Amy also considered purchasing a printer that costs $4,000 and depreciates by 25% each year. Which printer will have more value in 5 years? Justify your answer by showing/explaining your work.

Answers

Given that the printer depreciates at the rate of 14% p.a. This has been modeled by the function V=2400(1-0.14)^t, this follows an exponential form given by
y=a(b)^x
where:
V=y
a=2400
b=1-0.14
x=t
thus:
Part A: Explain what the parameter 2,400 represents in the equation of the function.
The parameter 2400 represents the initial value of the printer at time t=0. This is the original value.

Part B: What is the factor by which the printer depreciates each year?
The factor of depreciation is 14% percent. This is the rate at which the printer depreciates and it accounts for the value of the printer at the end of every year.

Part C: Amy also considered purchasing a printer that costs $4,000 and depreciates by 25% each year. Which printer will have more value in 5 years?
Value after 5 years of the $2400 printer that depreciates at 14% per year will be:
V(t)=2400(1-0.14)^5=$1,129.025

Value after 5 years of the $4000 printer that depreciates at 25% per year will be:
F(t)=4000(1-0.25)^t
F(5)=4000(1-0.25)^5=$949.22

The printer that costs $2400 will be more valuable compared to the printer that cost $4000

You've probably got one of those "need to do eventually but not today" lists residing somewhere in your brain. Eat more salad. Paint the bathroom. Jog 30 minutes a day. Learn a foreign language. And while you normally hit snooze when these mental reminders go off in your brain, it may just be the one time when you might actually make an effort to get one or two of these items moved into the "let's do soon" list. The possibilities of a new year always seem to inspire those infamous resolutions and get us jump started on things we should have done a long time ago. But before you get carried away with this year's list, why don't you pencil in "write a will" at the top? Believe it or not, getting your will done this year might turn out to be the most important resolution you can make. First and foremost, think about your kids. You've made a lifelong commitment to love and nurture them, but you can only carry out your desires on this side of the grave. If you haven't made provision for their guardianship upon your death, then the courts and the law will make that decision for you. Do you want the determination of your children's care and training entrusted to a faceless legal system? If not, then for no other reason write a will so that you can be the one to decide who will best raise and love your children when you aren't around to do it yourself.

A will tells everyone what will happen to your money, possessions, and property when you die. There are many reasons to make a will. First, it will be easier for your family and friends to sort everything out. Without a will, it can be very stressful and time consuming to figure out how to allocate everything. Plus, if you don't have a will the law will decide how to allocate it and this might not be the way you want it. It can be especially important to write a will if you have children or other family that depend on you financially. This way, you can leave them the most possible to help them even when you are no longer alive. By writing a will, you can decrease the amount of inheritance tax that might need to be paid on any property and money that you will leave behind. Ultimately, by writing a will you will be able to decide who you leave your money, possessions, and property to when you die which can be very important to some individuals.

If 6 is 30% of a value,
a.what is 70% of that value? b8 is omlwhat is 10%of the value?

Answers

70% is 14. And 10% is 2

so if 6 is 30% of a value we know that the value let's say x multiplied by .3 is 6. so we can write an equation to solve for the value x
[tex].3x = 6 \\ x = \frac{6}{.3} \\ x = 6 \times \frac{10}{3} = 20[/tex]

so our value is 20 and as 10% of 20 is 2 we see 30% of 20 is 2×3=6

now we want to find 70% of 20 and 10% of 20. we already know 10% of 20 is 20 because to find 10% we take the value 20.0 and move the decimal 1 place to the left which gives us 2.0. To find 70% we can multiply 20 by .7 or since we know 10% just multiply that by 7 because 10% ×7 =70% so 2×7=14 so 14 is 70% of 20. solving the other way we get
[tex]20 \times .7 = 20 \times \frac{7}{10} = \frac{20}{10} \times 7 = 2 \times 7 \\ = 14[/tex]
so we can see we are correct!

A newly hatched channel catfish typically weighs 0.3 grams. During the first 6 weeks of life, its growth is approximately exponential, increasing by about 10% each day. Find the weight at the end of four weeks. (Hint: Be sure to change the number of weeks to days before plugging into the formula!) Formula: A=C(1+r)t

0.53g
4.33g
16.43g
1.14g

Answers

Answer: second option 4.33 g

Explanation:

1) The formula is given: A = C(1+r)ˣ ↔ (I used x instead of t just do to limitations of the math editor. Keep in mind that here x is time in days.

2) r is the rate of increasing given: 10% = 10/100 = 0.1

3) C is the initial weight and A is the final weight after x (or t) days.

4) The equation leads to:

A = 0.3 (1 + 0.1)ˣ = 0.3(1.1)ˣ

x = number of days = 7 × number of weeks = 7 × 4 = 28 days

4) Compute:

A = (0.3g)(1.1)²⁸

A = 4.33g ← answer

Final answer:

The weight of a newly hatched channel catfish after four weeks of exponential growth is approximately 1.14 grams.

Explanation:

To find the weight at the end of four weeks, we need to convert the number of weeks to days since the growth rate is given in terms of daily percentage increase. The formula to calculate exponential growth is A = C(1 + r)^t, where A is the final weight, C is the initial weight, r is the growth rate, and t is the number of periods. In this case, C = 0.3 grams, r = 0.10 (10% daily increase), and t = 4 weeks x 7 days/week = 28 days. Plugging in these values, we get A = 0.3(1 + 0.10)^28. Evaluating the expression, the weight at the end of four weeks is approximately 1.14 grams.

An electrician can wire a house in 20 hours. if she works with an apprentice, the same job can be completed in 12 hours. how long would it take the apprentice, working alone, to wire the house?

Answers

Final answer:

It would take the apprentice 30 hours to wire the house alone.

Explanation:

Let's assume that the work done by the electrician alone in 1 hour is represented by E, and the work done by the apprentice alone in 1 hour is represented by A. According to the given information, the electrician can wire the house in 20 hours, so E = 1/20. When the electrician and the apprentice work together, they can wire the house in 12 hours, so their combined work in 1 hour is represented by (E + A) = 1/12.

To find out how long it would take the apprentice to wire the house alone, we can subtract the work done by the electrician in 1 hour (E) from the combined work done by both the electrician and the apprentice in 1 hour (E + A), which gives us A = (E + A) - E. Substitute the values:

A = (1/12) - (1/20) = (20 - 12) / (12 x 20) = 8 / 240 = 1/30.

So, the apprentice can wire the house alone in 30 hours.

Below is the graph of y=b^x. Find b.

Answers

y = b^x

when x = 1
y = b^1
y = b

Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5

To confirm this

From the graph,

When x = -1, y = 2
Since y = b^x
2 = b^-1
2 = 1/b
2b = 1
b = 0.5

When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5

Therefore, it is conformed that b = 0.5

Functions can be represented as equations, and equations can be represented as functions.

The value of b is 1/2

The graph is given as:

[tex]\mathbf{y = b^x}[/tex]

From the graph, we have the following point:

(x,y) = (-1,2)

Substitute these values in the function

[tex]\mathbf{2 = b^{-1}}[/tex]

Rewrite as:

[tex]\mathbf{2 = \frac{1}{b}}[/tex]

Multiply both sides by b

[tex]\mathbf{2b = 1}[/tex]

An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 20mL. The height of the water rose to 30.2mL. If the mass of the stone was 25g what was its density?

Answers

Answer:
density = 2.4509 g/ml

Explanation:
1- getting the volume of the stone:
since the stone has an irregular shape, the volume of the stone would be equal to the increase in the volume of the stone after placing the stone in it.
Initial volume of water = 20 ml
Final volume of water = 30.2 ml
volume of stone = final volume of water - initial volume of water
volume of stone = 30.2 - 20 = 10.2 ml

2- getting the density of the stone:
we have:
volume of stone = 10.2 ml
mass of stone = 25 g
Therefore, we can get the density as follows:
density = mass / volume
density = 25 / 10.2
density = 2.4509 g/ml

Hope this helps :)

Final answer:

To find the density of the stone, subtract the initial volume of water from the final volume, then divide the mass of the stone by the volume. The density of the stone is 2.45 g/cm³.

Explanation:

In order to find the density of the stone, we first need to calculate its volume. The volume can be determined by subtracting the initial volume of water in the graduated cylinder from the final volume with the stone submerged. In this case, the volume of the stone is 30.2 mL - 20 mL = 10.2 mL.

Next, we can use the formula for density: density = mass/volume. Plugging in the given values, we have density = 25 g/10.2 mL.

Since density is mass divided by volume, we need to convert mL to g/cm³. 1 mL is equal to 1 g/cm³. Therefore, the density of the stone is 25 g/10.2 mL = 2.45 g/cm³.

Answers

For questions like these, I believe you use permutations. Basically you mutiply all the numbers in the set together. so in this case there are five, so you multiply numbers 1-5 together in order to get the total arrangements possible.

For example :
[tex]1 \times 2 \times 3 \times 4 \times 5 = 120[/tex]
There you go :)

Final answer:

The question relates to combinatorial mathematics and asks for possible arrangements of 5 cars of three different colors. Treating identical colors as one entity, we find that there are 6 ways to arrange the color groups and another 6 ways to arrange the red cars among themselves, resulting in 36 possible arrangements.

Explanation:

The subject of this question is combinatorial mathematics. We're asked how many different arrangements there are if we have 5 cars to be displayed in 5 parking spaces, with the condition that the cars are identical besides their color; 3 of them are red, 1 is blue, and 1 is yellow.

Since three cars are identical (red ones), we treat them as one. So initially, we have three 'entities' to arrange: the red group (of 3 cars), the blue car, and the yellow car. These can be arranged in 3! (which means 3 factorial, or 3 * 2 * 1) = 6 ways.

However, within the red group, those 3 red cars can be arranged amongst themselves in 3! = 6 ways.

Therefore, to get the total number of arrangements, we multiply these results together, giving us: 6 * 6 = 36 different arrangements.
