The scenario that could be modelled with an exponential function would be; D) when Tim adds $10 to his savings account each week.

Noted that a continuous compounding function is an exponential function. So, we need to find the situation where the principal amount is invested for an infinitely long time.

A.) It is known that the amount is invested and a certificate of deposit is taken the amount will be invested for a fixed period of time. so this is not a continuous compound function.

B.) The amount put into the account and taken out of the account varies for each term. Thus, this is not a continuous function.

C.) As in Jaylon's account the money is reduced by $125 every month, therefore, at a certain point, it will become zero therefore, this is not a continuous compound function.

D.) Since Tim adds $10 to his saving account every month, and there is no time specified, also the account will be always positive therefore, it is continuous compound function.

Hence, the scenario that could be modelled with an exponential function is D.

Answer:  The continuous interest rate at which the money was invested is approximately 15.4%.

Step-by-step explanation: We can use the formula for continuous compounding to find the value of r:

A = Pe^(rt)

Where A is the final value, P is the initial investment, e is the base of the natural logarithm, r is the continuous interest rate, and t is the time.

Plugging in the given values, we get:

$100,000 = $25,000e^(r*18)

Dividing both sides by $25,000 and taking the natural logarithm of both sides, we get:

ln(4) = 18r

Solving for r, we get:

r = ln(4)/18 ≈ 0.154

Multiplying by 100 to convert to a percentage and rounding to one decimal point, we get:

r ≈ 15.4%

Therefore, the continuous interest rate at which the money was invested is approximately 15.4%.

Step-by-step explanation:

Claude would have to rotate the wheel 54 times to complete a 100m unicycle race. And the unicycle moves 1.884 meters when the wheel turns once.

How to solve the question?

A) To determine how far the unicycle moves when the wheel turns once, we need to find the circumference of the wheel.

The formula for the circumference of a circle is:

C = πd

where C is the circumference, π (pi) is a mathematical constant equal to approximately 3.14, and d is the diameter of the circle.

So, in this case, the circumference of the unicycle wheel is:

C = πd = 3.14 x 60cm = 188.4cm

To convert centimeters to meters, we need to divide by 100:

188.4cm ÷ 100 = 1.884m

Therefore, the unicycle moves 1.884 meters when the wheel turns once.

B) To determine how many times the wheel must rotate to travel 100m, we need to divide the distance by the distance covered in one revolution of the wheel, which is the circumference.

Using the circumference we calculated above, we can divide the total distance by the distance covered in one revolution:

100m ÷ 1.884m/revolution ≈ 53 revolutions

Therefore, Claude must rotate the wheel approximately 53 times to travel 100m. Since he cannot rotate the wheel partially, we must round up the number of revolutions to the nearest whole number, which is 54.

In conclusion, Claude would have to rotate the wheel 54 times to complete a 100m unicycle race.

a) What is the initial height of the object?

The initial height of the object is the height at t = 0. Substituting t = 0 in the equation for s(t), we get:

s(0) = -8.05(0)^2 + 35(0) = 0

Therefore, the initial height of the object is 0 feet, which means it is on the surface of the planet.

b) What is the maximum height reached by the object?

The maximum height reached by the object occurs at the vertex of the parabolic function s(t). The vertex of a parabola of the form ax^2 + bx + c is given by the formula:

t = -b/2a

In this case, a = -8.05 and b = 35. Substituting these values, we get:

t = -35/(2*(-8.05)) = 2.17 seconds (rounded to two decimal places)

To find the maximum height, we substitute t = 2.17 seconds in the equation for s(t):

s(2.17) = -8.05(2.17)^2 + 35(2.17) = 34.09 feet (rounded to two decimal places)

Therefore, the maximum height reached by the object is 34.09 feet.

c) When does the object hit the ground?

The object hits the ground when its height s(t) is equal to 0. We can solve the equation -8.05t^2 + 35t = 0 to find the times when s(t) = 0:

-8.05t^2 + 35t = 0

t(-8.05t + 35) = 0

t = 0 or t = 4.34 seconds (rounded to two decimal places)

The first solution, t = 0, corresponds to the initial position of the object, so we can discard it. Therefore, the object hits the ground after approximately 4.34 seconds.

Answer:

circumference of the circle is 25.13 cm

area of the circle is 50.27 square cm

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr.

Using this formula, we can find the circumference of the circle with radius 4cm:

C = 2πr

C = 2π(4)

C = 8π

C = 25.13

So the circumference of the circle is 25.13 cm (rounded)

The formula for the area of a circle is A = πr^2.

Using this formula, we can find the area of the circle with radius 4cm:

A = πr^2

A = π(4^2)

A = 16π

A = 50.27

So the area of the circle is 50.27 square cm (rounded)

Step-by-step explanation:

First, we need to determine the amount of time each sales representative can spend on selling each week.

A 40-hour work week is equivalent to 2,400 minutes (40 hours x 60 minutes/hour).

If 50% of each rep's time is consumed by non-selling tasks and travel time, then they have 1,200 minutes (2,400 minutes x 50%) available for selling each week.

Each sales call takes 32 minutes, so a rep can make 75 sales calls per week (1,200 minutes available for selling ÷ 32 minutes per sales call).

It takes 10 visits per year to acquire and service each account, which means a sales rep needs to visit each of the 688 potential adopters 10 times per year, or 6,880 visits in total per year.

Each sales rep can make 75 visits per week, which means they can make 3,900 visits per year (75 visits per week x 52 weeks in a year).

Therefore, Shannon will need to hire 1.76 sales reps (6,880 total visits needed ÷ 3,900 visits per year per sales rep).

Rounding up to the nearest 1/10 of a rep, Shannon should hire 1.8 sales reps.

The margin of error is 0.35

According to Amelia's results, 42% of students prefer coffee in the morning.

If the margin of error is ±0.072, between 689 and 978 students at the school prefer coffee.

How do we calculate for the percentage and margin of error?

To calculate percentages;

total coffee takers/ total number of students surveyed x 100.

TCT= 63  TSS = 150 which then becomes 63/150x 100 = 42

To calculate the margin of error;

TCT/TSS - ME  and TCT/TSS + ME, which becomes

63/150 + 0.072 = 0. 49

63/150 - 0.072 = 0.35

Next, we calculate the highest and lowest number by saying;

0.49 x total number of students in the school  1,981 =

0. 35 x total number of students in the school  1,981 =

Step-by-step explanation:

The solution to the differential equation is A. y = sin⁻¹(√2 - cosx)

To find the solution of the differential equation dy/dx = sinx/cosy, passing through the point (π/4, π/4) we proceed as follows.

dy/dx = sinx/cosy

So, cosydy = sinxdx

Integrating both sides, we have that

∫cosydy = ∫sinxdx

siny = -cosx + c

At the point (π/4, π/4), we have that

siny = -cosx + c

sin(π/4) = -cos(π/4) + c

1/√2 = -1/√2 + c

c = 1/√2 + 1/√2

c = 2/√2

c = 2/√2 × √2/√2

c = 2√2/2

c = √2

So, substituting the value of c into the equation, we have that

siny = -cosx + c

siny = -cosx + √2

Taking inverse sine of both sides, we have that

sin⁻¹siny = sin⁻¹(-cosx + √2)

y = sin⁻¹(√2 - cosx )

The solution is A. y = sin⁻¹(√2 - cosx)

The answer is (C) This is not a functional relationship.

A functional relationship is a relationship between two variables in which each input (independent variable) maps to exactly one output (dependent variable).

In other words, for every value of x, there is only one corresponding value of y that satisfies the equation.

Here we have

The equation x² + y² = 10  

The equation x²+ y² = 10 represents a circle with a center at the origin and a radius of √10.

Since a circle passes through multiple points with the same x-coordinate or y-coordinate, it cannot be represented as a function.

Hence, the relationship shown in the equation is not a functional relationship.

Answer:

48 + 12 is equivalent to 60.

To calculate the percent change in population, we first need to find the difference between the two population numbers, then divide that difference by the original population, and finally, multiply by 100 to get the percentage change.

The difference in population is:

50,000 - 48,000 = 2,000

To find the percent change, we divide the difference by the original population:

2,000 / 50,000 = 0.04

Finally, we multiply by 100 to get the percentage change:

0.04 x 100 = 4%

Therefore, the percent change in the town's population from 2000 to 2010 is a decrease of 4%.

Step-by-step explanation:

To find the percent change, we need to calculate the difference between the initial population and final population, and then divide it by the initial population.

Change in population = Final population - Initial population

= 48,000 - 50,000

= -2,000

Since the change is negative, it means that there was a decrease in the population.

Percent change = (Change in population / Initial population) x 100%

= (-2,000 / 50,000) x 100%

= -0.04 x 100%

= -4%

Therefore, the percent change in the town's population is -4%.
