7. The average comic book sold for $2.25 in 1994 and for $3.99 in 2016.

a) Write a linear function that approximates the average cost of comic books
over time (t) starting in 1994.

b) Predict the average cost of a comic book in 2020.

- c) In about what year will the average cost have gone over $5?

Answers

Answer 1

The linear function to find average cost will be A=$(2.25+0.079t), average cost of a comic book in 2020 = $4.3, Average cost will be $5 in year 2029.

what is a linear function?

A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0.  Although the linear functions are also represented in terms of calculus as well as linear algebra. The only difference is the function notation. Knowing an ordered pair written in function notation is necessary too. f(a) is called a function, where a is an independent variable in which the function is dependent. Linear Function Graph has a straight line whose expression or formula is given by;

                                                    y = f(x) = px + q

It has one independent and one dependent variable. The independent variable is x and the dependent one is y. P is the constant term or the y-intercept and is also the value of the dependent variable. When x = 0, q is the coefficient of the independent variable known as slope which gives the rate of change of the dependent variable.

Now

Initial value = $2.25 in 1994

cost in 2016 = $3.99

Therefore

3.99=2.25+2.25*r*22/100

r=0.079

where r=rate

then

Average cost=initial value+0.079t

Hence

A=$(2.25+0.079t)

where t=time (given year - 1994)

cost in 2020=$(2.25+0.079*26)

cost in 2020=$4.3

Now for A=$5

5=2.25+0.079t

t=35years

Hence Average cost will be $5 in year 2029.

Step-by-step explanation:

Solve for y.

25 = y2

y =
or

Answers

Answer:

y=5 or y=−5 it does not matter either one

Step-by-step explanation:

25=y2

Step 1: Subtract y^2 from both sides.

25−y2=y2−y2

−y2+25=0

Step 2: Subtract 25 from both sides.

−y2+25−25=0−25

−y2=−25

Step 3: Divide both sides by -1.

−y2

−1

y2=25

Step 4: Take square root.

y=±√25

y=5 or y=−5

Answer:

Let's solve your equation step-by-step.

25 =  [tex]y^{2}[/tex]

Step 1: Subtract y^2 from both sides.

25 − [tex]y^{2}[/tex] = [tex]y^{2}[/tex] − [tex]y^{2}[/tex]

−[tex]y^{2}[/tex]+ 25 = 0

Step 2: Subtract 25 from both sides.

−[tex]y^{2}[/tex]+ 25 − 25 = 0 − 25

−[tex]y^{2}[/tex] = − 25

Step 3: Divide both sides by -1.

[tex]y^{2}[/tex]  / −1  =  −25  / −1

[tex]y^{2}[/tex] =25

Step 4: Take square root.

y = ± √25

y = 5 or y = −5

Answer:

y = 5 or y = −5

Samantha works in a chocolate factory at a conveyor belt that is 18 inches wide and moves large amounts of chocolate to packaging. She counts 225 chocolates in a rectangular section of the conveyor belt measuring 6.5 inches long and 18 inches wide. What is the approximate number of chocolates per square inch of the conveyor belt, rounded to the nearest hundredth?

Answers

Answer:

1.92 chocolates per in²

Step-by-step explanation:

Given that:

Dimension of conveyor belt :

6.5 inches long and 18 inches wide (6.5in * 18in)

Area of conveyor belt = 6.5 * 18 = 117 in²

Number of chocolate = 225

Number of chocolates per square inch :

225 / 117

= 1.9230769 chocolates

= 1.92 chocolates per in²

    [tex]\frac{dy}{dx} = \frac{2x +2 y- ycosxy}{x(cosxy-2)}[/tex]

Step-by-step explanation:

Step(i):-

Given

        sin xy = x² + 2xy ...(i)

Apply

       [tex]\frac{d}{dx} UV = U^{l} V + U V^{l}[/tex]

     [tex]\frac{d}{dx} x^{n} = nx^{n-1}[/tex]

Differentiating equation (i) with respective to 'x', we get

      [tex]cosxy \frac{d}{dx} (xy) = 2x + 2( x\frac{dy}{dx} + y(1))[/tex]

      [tex]cosxy (x\frac{dy}{dx} +y(1)) = 2x + 2( x\frac{dy}{dx} + y(1))[/tex]

     [tex]cosxy (x\frac{dy}{dx}) + ycosxy = 2x + 2( x\frac{dy}{dx}) +2 y)[/tex]

   [tex]cosxy (x\frac{dy}{dx}) - 2( x\frac{dy}{dx}) = 2x +2 y- ycosxy[/tex]

   [tex](cosxy-2) (x\frac{dy}{dx}) = 2x +2 y- ycosxy[/tex]

Answers

Answer:

About 2,800.

Step-by-step explanation:

2,000(1.05)^x

x =7.

2,000(1.05)^7

find 1.05 to the power of 7, which is 1.4071....

then times 1.4071... by 2,000. You will get 2,814.2 - or about 2,800.

The population of butterflies after 7 years will be approximately 2814 butterflies.

What is an exponential function?

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

The formula f(x) = 2000(1.05)ˣ can be used to model the population of butterflies after x years, where x is a non-negative integer.

Here, the initial population is 2000.

To find the population of butterflies after 7 years, we can substitute x = 7 into the given function and evaluate:

f(7) = 2000(1.05)⁷

Using a calculator, we get:

f(7) ≈ 2814

Therefore, the population of butterflies after 7 years will be approximately 2814 butterflies.
