Help please — How many whole months will it take for a motorbike valued at £2550 to depreciate to less than £1200 if depreciation is at a rate of 5% per month?

Answers

Using Continuous compounding in 15.07 months, the bike's value will be less than £1200.

What is Continuous compounding?

Continuous compounding refers to the process of compounding interest at an infinitely frequent rate. It is a way to figure out how much an asset will depreciate over time or how much an investment will increase.

[tex]A=Pe^{rt}[/tex]

where:

A is the asset's final value

P is its initial value

r is the interest rate (or rate of depreciation in the case of a depreciating asset)

t is the time periods (months, years, etc.)

A= 1200

P= 2550

r= -0.05

We want to find t, so we can rearrange the formula to solve for t:

[tex]t=\frac{log\frac{A}{P}}{r}\\\\t=\frac{log\frac{1200}{2550} }{-0.05} \\ \\t=15.07months[/tex]

In 15.07 month motorbike value will depreciate to less than £1200

b. An educator claims that both methods of instruction are equally effective. Does the confidence interval contradict this claim?

Answers

Answer:

See below for answers and explanations

Step-by-step explanation:

Part A:

Check conditions for a 2-sample t-interval:

Random sample? √

Is the sample size no more than 10% of the population? √

Are both samples approximately normal? √

Construct the 95% confidence interval:

On a TI-84, click on "Stat", scroll to "Tests", and select "2-SampTInt". Put your data into 2 lists and set C-Level to be 0.95 to represent a 95% confidence level. Make sure the data isn't pooled, and press "Calculate" to obtain your results. You will see that the 95% confidence interval for the difference between the mean scores for the two types of instruction is {-6.042,8.1175}

Part B:

The confidence interval does not contradict the claim because 0 is contained within the 95% confidence interval, so it is quite possible that there is no difference between the mean scores for the two types of instruction.

A circle is created in the plane by each point that is a specific distance from another point (center). Thus, it is a curve made up of points that are separated from one another by a defined distance in the plane. Every pair of points in a circle's closed, two-dimensional plane are evenly spaced apart from the "center." A circular symmetry line is made by drawing a line through the circle.

An office uses paper drinking cups in the shape of a cone, with dimensions as shown. To the nearest tenth of a cubic inch, what is the volume of each drinking cup?

Answers

The volume of each drinking cup is 7.9 cubic inches.

What is the volume?

An office uses paper drinking cups in the shape of a cone, with dimensions as shown.

The formula provides the volume of a cone.

V =  (1/3) * π * r² * h.

We can find the solution by entering the already-known data into the formula.

d = 2.75 m.

Since radius is half of d, we can say

0.5 * 2.75 = 1.375 in.

4 inches is listed as the height.

The result of plugging all of them into the original formula is:

V = (1/3) * π(1.375)² (4) = 7.9

Our final response, rounded to the closest tenth, is:

V = 7.9 cubic inches.

The volume of each drinking cup is 7.9 cubic inches.

The complete question is An office uses paper drinking cups in the shape of a cone, with dimensions as shown. To the nearest tenth of a cubic inch, what is the volume of each drinking cup?

Let x be the number of years and y be the allowance. The initial allowance is $8, this means at x = 0, y = 8

Since it increases by 20% each year, i.e 100% + 20% = 1 + 0.2 = 1.2. This means that b = 1.2

On a certain hot summer's day, 379 people used the public swimming pool. The daily prices are $1.75 for children and $2.00 for adults. The
receipts for admission totaled $693.50. How many children and how many adults swam at the public pool that day?

Answers

Let, number of children and adults swam at the public pool that day is x and y.

So, x + y = 379   .....1)

It is given that daily prices are $1.75 for children and $2.00 for adults.

Also, the  receipts for admission totaled $693.50.

So, 1.75x + 2y = 693.50  .....2)

Putting value of y from equation 1 to equation 2 , we get :

1.75x + 2( 379 - x ) = 693.50

758 - 2x + 1.75x = 693.50

0.25x = 64.5

x = 258

So, y = 379 - 258 = 121

Therefore, number of children are 258 and adults are 121.

PLEASE HELP. IVE BEEN STUCK ON THIS PROBLEM FOR THE PAST HOUR.

Answers

Answer:

1 ≤ x < 6

Step-by-step explanation:

Okay so the answer is 1 ≤ x < 6, and the way you solve it is pretty simple :)

First: Eliminate the functions of the inequality, leaving it to just being an inequality. You have to understand that the function is decreasing on its domain, so the sign will reverse itself once you take away g(x)

This should take you from having [tex]g(x^{2} )>g(5x+6)[/tex]  to having [tex]x^2<5x+6[/tex]. From here you solve the inequality to get [tex]-1<x<6[/tex], although you aren't done.

Afterwards you take into account the domain, which restricts everything to being greater than or equal to one. This means that your inequality changes to 1 ≤ x < 6.

yw and good luck w ur rsm hw haha

lmk if this was helpful :P

The solution of inequality is 1 ≤ x < 6.

What is Function?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Remove the inequality's functions, leaving it as an inequality alone.

As, the function is decreasing on its domain, the sign will change if g(x) is removed.

We have

g (x²) > g (5x+6)

x² > 5x +6

For the above equation the interval is -1 < x < 6.

The domain, which limits everything to being larger than or equal to one, is then taken into consideration.

So, the inequality is 1 ≤ x <6.

The equation of the line is y = 4x + 1 , where the slope of the line is m = 4

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the number of blocks be y

Let the stage number be x

Let the first point be represented as P = P ( 1 , 5 )

Let the second point be represented as Q = Q ( 2 , 9 )

Now , the slope of the line between the points be

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 9 - 5 ) / ( 2 - 1 )

Slope m = 4

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 5 = 4 ( x - 1 )

On simplifying the equation , we get

y - 5 = 4x - 4

Adding 5 on both sides of the equation , we get

y = 4x + 1

Therefore , the value of A is y = 4x + 1

Hence , the equation of line is y = 4x + 1
