[tex]\frac{dx}{dt}[/tex] = k.x.[1000 - x] ;  

where k is the proportionality  constant

Step-by-step explanation:

Let

The number of people who are infected with the flu = x(t)

Total number of students = 1000

So,

Total number of student who do not expose with the flue = 1000 - x(t)

As given,

We have to find the differential equation such that

The rate at which the disease spreads is proportional to the number of interactions between the number of students who have the flu and the number of students show have not been exposed to it.

⇒[tex]\frac{dx}{dt}[/tex] ∝ x(t) . [ 1000 - x(t) ]

⇒[tex]\frac{dx}{dt}[/tex] = k.x.[1000 - x] ; where k is the proportionality  constant

Step-by-step explanation:

17×6×h=1020

102h=1020

h=1020/102=10

h=10 cm

At a speed of 48 miles per hour, it would take 13 hours.

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route.

Given:

The amount of time needed to complete a certain road trip, t, varies inversely with the speed of a vehicle, s. At a speed of 52 miles per hour, the trip will be complete in 12 hours.

Distance is constant.

And we know the formula:

Distance = speed x time

              = 52 x 12

              = 624 miles

Now to find the time:

Now for speed = 48 miles per hour

time,

t = distance / speed

 = 624/48

 = 13 hours

Therefore, 13 hours would it take at a speed of 48 miles per hour.

Answer:

65   3    46

Step-by-step explanation:

Answer:

a² + 1 = 65

18/2a = 3

6(d + 8) - 10d = 46

Step-by-step explanation:

a² + 1 when a = 8

first, plug in 8 for a.

begin simplifying by finding 8², which is just 8 · 8.

finish simplifying by adding 64 + 1.

therefore, when a = 8, a² + 1 = 65.

18/2a when a = 3

first, plug in 3 for a.

begin simplifying by multiplying 2 · 3.

finish simplifying by dividing 18 ÷ 6.

therefore, when a = 3, 18/2a = 3.

6(d + 8) - 10d when d = 1/2

(i'm going to convert 1/2 to 0.5 because i prefer working with decimals rather than fractions)

so... 6(d + 8) - 10d when d = 0.5

first, plug in 0.5 for d.

begin simplifying by distributing 6 to 0.5 and 8, which is just 6 · 0.5 and 6 · 8.

after distributing, your expression is 3 + 48 - 10(0.5).

continue simplifying by multiplying -10 · 0.5.

add 3 + 48.

finally, finish simplifying by subtracting 5 from 51.

therefore when d = 1/2 or 0.5, 6(d + 8) - 10d = 46.

Answer:

0.8104

Step-by-step explanation:

Answer:

0.8104

Step-by-step explanation:

Take the 0 out of the end of the 0.010 because there is no reason for it to be there.

Then you just multiply 81.04 by 1 because the rest of 0.01 is just zeros and the you get 81.04.

Then you count the decimal places in 0.01 which you get two so you move the decimal in 81.04 two times to the left.

Your answer should be .8104

====================================================

Explanation:

The first column is the list of x values we plug into the function. The second column describes what happens to those x inputs. Namely, we subtract off 2. In the first row, it shows 0-2 after replacing x with 0. This leads to the result of -2 since 0-2 = -2.

In the second row, we have the input x = 2 turn x-2 into 2-2 = 0. So that's why 0 goes in the blank for the second row.

In the third row, we have x-2 = 3-2 = 1. So we'll have 3-2 go in the first blank of row 3, and the value 1 go in the second blank of this same row.

Answer:

not: f(x) domain: x ≤ -2

f^-1(x) range: y ≤ -2

Step-by-step explanation:

The possible domain restriction for f(x) and its corresponding impact on f'(x) is f(x) domain: x < 1, f'(x) domain: x < 1.

There are many tools we can use to find the information of the relation which was used to form the graph.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.

If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

We are given that;

The graph of function

Now,

Looking at the graph, we can see that the function and its inverse are reflections of each other across the line y = x. This means that the domain of the inverse function corresponds to the range of the original function, and vice versa.

From the graph, we can see that the original function f(x) has a vertical asymptote at x = 1. This means that the function is undefined at x = 1.

Therefore, a possible domain restriction for f(x) is x < 1, which would exclude x = 1 from the domain. The corresponding impact on f'(x) would be that f'(x) would also be undefined at x = 1.

So, the answer that pairs a possible domain restriction for f(x) and its corresponding impact on f'(x) is:

f(x) domain: x < 1

f'(x) domain: x < 1

This is because the domain of f(x) is restricted to exclude x = 1, and the corresponding impact on f'(x) is that it is also undefined at x = 1.

Therefore, by the graphed function the answer will be f(x) domain: x < 1, f'(x) domain: x < 1.

Answer:

Step-by-step explanation:

Hello!

I think I can help.

Lets use the first problem and walk through it and I think it could help you with the others.

3/7 = ?/49

So basically with these problems you are working backwards. You are working right to left and dividing to figure out what you will need to multiply the other part of the fraction by.

So here we have 49 and 7 that line up with each other. (Always look for the fractions that line up horizontally)

Going right to left and dividing :

49 / 7

= 7

So we know that it was 7 x 7 to get that 49

So now we used the number we just found by dividing (7) and multiply it left to right by the other number to find the missing number (?).

If we do this we do :

3 x 7

= 21

And that is the missing number !

We plug that in right where the blank is (?) and we get :

3/7 = 21/49

I am not sure if you have to simplify this but you cant anyways. If you have questions about simplifying ask in the comments.

To check this we can actually multiply the side that had two numbers to begin with (the left side numbers) and multiply it by the number we found by dividing (7).

So we do this with 3/7 :

3 x 7 = 21

7 x 7 = 49

if we plug this back in we get :

21/49 = 29/49 and we know this is correct.

I hope this helps you solve the other problems. If you have any questions or are still confused with others please message me or comment and I will do what I can to help.  :)

Answer:

its letter A multiply and add

Answer:

D. 1/11.

Step-by-step explanation:

There are 12 pencils in the case.

Prob( first one is sharpened) = 4/12 = 1/3

Prob(second is sharpened) = 3/11

Prob(both sharpened) = 1/3 * 3/11

= 3/33

= 1/11.

The probability is 1/11 that both pencils will be sharpened which is the correct option(D).

The probability is defined as the possibility of an event being equal to the ratio of the number of outcomes and the total number of outcomes.

Given that,

Bonnie has 4 sharpened and 8 unsharpened pencils

So, there is a total of 12 pencils in the pencil case.

Let, the probability first one is sharpened is P(E₁)

The probability second one is sharpened is P(E₂)

P(E₁) = 4/12 = 1/3

P(E₂) = 3/11

Required probability both sharpened P(E) = P(E₁)×P(E₂)

Required probability both sharpened P(E) = 1/3 × 3/11

Required probability both sharpened P(E) = 3/33

Required probability both sharpened P(E) = 1/11.

Hence, the probability is 1/11 that both pencils will be sharpened.
