Gwendolyn draws a hotdog on graph paper using the scale shown below. The hotdog has a length of 999 units in the drawingWhat is the length, , c, m, of the actual hotdog?

Answers

Answer 1

The length of the actual hotdog is 15 cm

How to determine the length of the actual hotdog?

The graph that completes the question is added as an attachment

The length of the hotdog in the figure is given as

Length = 9 units

The scale is given as

Scale: 6 units = 10 cm

So, we have

6 * 9 units = 10 * 9 cm

Divide both sides by 6

So, we have

9 units = 15 cm

Substitute 9 units = 15 cm in Length = 9 units

Length = 15 cm

Hence, the length of the actual hotdog is 15 cm

Suppose you invest a dollars to earn an annual interest rate of r percent (as a decimal). After t years, the value of the investment with interest compounded yearly is A(t)=a(1+r) t . The value with interest compounded continuously is A(t)=a . e rt
b. Suppose you can earn interest at some rate between 0 \% and 5 \% . Use your. knowledge of the exponential function to explain why continuous compounding does not give you much of an investment advantage.

Answers

$1.051271 is the exponential function to explain why continuous compounding does not give you much of an investment advantage.

With an example, what is compound interest?

When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits. Consider that you have $1,000 in a savings account earning 5% interest annually. If you made $50 in the first year, your new balance would be $1,050.

Simple Interest: A = P(1+rt)

P: the principal, the amount invested

A: the new balance

t: the time

r: the rate, (in decimal form)

Ex 1 -  If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.

P = $1000, t = 2 years, r = 0.08.

A = 1000(1+0.08(2)) = 1000(1.16) = 1160

B) Suppose you invest $1 at 5% compounded yearly.

Suppose you invest $1 at 5% compounded continuously.

The 1st case gives you $1*(1.05)1 = $1.05

The 2nd case gives you $1*e0.05 = $1.05127

For each annual rate of change, find the corresponding growth or decay factor. -55 %

Answers

The decay factor for the annual rate of change of - 55 % is 0.45.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = - 55 % = - 55 / 100 = - 0.55

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (- 0.55)

B = 1 - 0.55

B = 0.45

Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.45.

What are rotation and reflection?

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape.

Rotation rule:

Rotation of a point through 180°, about the origin when a point A (x, y) is rotated about the origin O through 180° in the anticlockwise or clockwise direction, it takes a new position A' (-x, -y).

Reflection rule:

A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis.

By looking at the graph, we can see that the points (0,4) and (3, 3), then the slope will be:

A package of a 8 count AA batteries cost 6.40. A package of 20 count AA batteries cost 15.80. Which statement about the unit prices is true?

Answers

Answer: A statement that is true is the package of 8 count AA batteries cost a cent more than the package of 20 count AA batteries.

Calculation: We are trying to find the unit rate: To identify it, we can start off initially by acknowledging that an 8 count package costs $6.40. Dividing this by 8 will give us our unit rate for the cost of one AA battery.

$6.40 / 8 batteries = $0.80 per battery

In a package of 8 count batteries, each battery costs $0.80.

We can apply the same process for the unit rate of a package of 20 count batteries. This would look like:

$15.80 / 20 batteries = $0.79 per battery

In a package of 20 batteries, each battery is $0.79.

Explanation: Seeing both of the unit rates, we know that $0.79 is less than $0.80. Because of this, it costs a cent more to get a single battery from an 8 count set of batteries than it would to get a singular battery from a 20 count set of batteries.

Final answer: It costs one more cent per battery for an 8 count battery than a 20 count battery. The statement about the unit prices that is true is the 20-count batteries have a lower price than the 8-count batteries.

(log x)² = log x²

Answers

The given logarithmic representation i.e., (log x)² = log x² is true only for x = 1 and 100 and for rest it is not valid.

Given that, (log x)² = log x², let's proceed to simplify this in order to reach at the conclusion part.

(log x)² = log x²

(log x)² = 2log x

(log x)² - 2log x = 0

log x(log x - 2) = 0

⇒log x = 0 or log x - 2 = 0

Now, put log x = 0

⇒ x = 1

Now, put log x - 2 = 0

log x = 2

log x = 10²

x = 100

Hence, we got two values for x one is 1 and other is 100. Now, putting one by one in (log x)² = log x² in order to reach at the conclusion.

Put x = 1 in (log x)² = log x², we get

(log 1)² = log 1²

0 = 0²

0 = 0

⇒ true for x = 1

Now, put x = 100 in (log x)² = log x² , we get

(log 100)² = log 100²

2² = 2log 100

4 = 2 x 2

4 = 4

⇒ true for x = 100

So, (log x)² = log x² is true only when x = 1 and 100 for rest it is false.

Identify the percentage of growth or decay for the exponential function: y = 18(0.75) x

Answers

The percentage of decay for the exponential function: y = 18(0.75) x is 25%.

How to illustrate the information?

This equation represents exponential decay. Whenever the base is less than 1, the function represents decay. When the base is greater than 1, the function represents growth. In this case, the base is 0.75 which is less than 1, representing decay.

The formula for exponential decay is y=a(1-r)x.

r is the decay rate, expressed as a decimal.

In this case, r = 1 - 0.75 = 0.25 which represents 25%.

Exponential equations are those in which the variables appear as exponents.

Exponential equations, for example, take the form a∧x = b∧y.Should use property of equality of the exponential functions to solve exponential calculations with the same base.If b is not a positive number, then b∧x = b∧y if but only if x = y. Throughout other words, is if bases are exactly the same, the exponents must also be the same as well.If the bases are not the same, accomplish the exponential equations using logarithms.

Now, for the stated equation 2 e³x=16;

Divide both side by 2

=> e³x = 8

=> x = 8/ e³

As, we are aware of the exponential function 'e' that is the value of e = 2.72...

Substitute the value of the exponent 'e' in the obtained expression.

=> x = 8/ (2.72)³

Answers

The price of the cheaper vehicle is $39,000

Calculating Cost

From the question, we are to determine the price of the cheaper vehicle

Let the cost of one of the cars b $x

and the cost of the other car be $y

From the given information,

The total price for two cars at a dealership is $108,000

That is

x + y = 108000   ----------- (1)

and

one car’s price is $9000​ less than twice the other

x = 2y - 9000       ----------- (2)

Put equation (2) into equation (1)

x + y = 108000

2y - 9000 + y = 108000

2y + y - 9000 = 108000

2y + y = 108000 + 9000

3y = 117000

y = 117000/3

y = 39000

∴ The price of one of the vehicles is $39,000

Substitute this value into equation (2)

x = 2y - 9000

x = 2(39000) - 9000

x = 78000 - 9000

x = 69000
