Look at problem 3. What is the greatest number of whole liters of water you could pour into a one-gallon container without it overflowing? Explain your answer.

Answer:

Step-by-step explanation:

To find the value of y at the point where x=1, we can substitute x=1 into the equation:

x^2+xy+y^3=1

1+y+y^3=1

y+y^3=0

y(y^2+1)=0

y=0 or y=-1 or y=1

To find the value of y' at the point where x=1, we need to take the derivative of the equation with respect to x:

2x + y + xy' + 3y^2y' = 0

y' = -(2x+y)/(3y^2+x)

When x = 1, y' = -(2(1)+y)/(3y^2+1)

To find the value of y'' at the point where x=1, we need to take the derivative of the equation with respect to x again:

2 + y' + xy'' + 3(2y)(y') = 0

y'' = -(2+y')/(3(2y)+(x))

When x = 1, y'' = -(2+y')/(3(2y)+(1))

To find the value of y''' at the point where x=1, we need to take the derivative of the equation with respect to x one more time:

y'' + xy''' + 3(2y')(y') + 3y(3y)(y') = 0

y''' = -(y'' + 3(2y')(y') + 3y(3y)(y'))/(x)

When x = 1, y''' = -(y'' + 3(2y')(y') + 3y(3y)(y'))/(1)

It is important to note that to find the exact value of y, y', y'', y''' we need to find the value of y in the equation x^2+xy+y^3=1 and substitute it into the derivative equations, but without the equation solved we can't find the exact values.

The time required for the population to triple is nearly 8 years if the population of a community is known to increase at a rate proportional to the number of people present at time t and an initial population p0 has doubled in 5 years.

Given that the population is increasing at a rate proportional to the number of people present at time t.

the population growth is modeled by the following differential equation:

[tex]\frac{dP(t)}{dt} = kP(t)[/tex]

P(t) = Po[tex]e^{kt}[/tex]           ..(1)

Initially given that population doubled in five years

i.e. P(5) = 2Po

Putting it in equation(1)

2Po = Po[tex]e^{5k}[/tex]

taking logs is both sides

ln 2 = 5k

k = ln2/5 = 0.1386

therefore, P(t) = Po[tex]e^{0.1386t}[/tex]

Now, the time required for the population to triple or P(t) 3Po

3Po = Po[tex]e^{0.1386t}[/tex]

ln3 = 0.1386t

or t = 7.9265 = 7.9

Therefore, the time required for the population to triple is nearly 8 years.

Solving a formula for a variable means rewriting the formula so that the variable is isolated on one side of the equation. This is useful in algebraic equations when trying to solve for a certain variable in order to find the value of that variable.

This means that all of the other terms in the equation will be on the opposite side of the equation, and the variable will be alone with no other terms. r example, if you have the equation 2x + 5 = 15, you would want to solve for x. To do this, you would need to move the 5 to the other side of the equation, and then divide both sides by 2. This would leave you with x = 5, which is the solution for the equation.

Answer:

Let's call the number of soldiers that should leave the group as x.

We know that the group of 30 soldiers has enough food for 40 days. And we want to find the number of soldiers that should leave the group so that the food is enough for 100 days for remaining soldiers.

We can use the proportion of soldiers to days of food to find the number of soldiers needed for 100 days of food.

30/40 = (30-x) / 100

We can cross-multiply and then solve for x:

1200 = 30x - x^2

x^2 + 30x -1200 = 0

x = 20 or x = -40

20 is the valid solution, so 20 soldiers should leave the group.

So, 20 soldiers should leave the group so that the food is enough for 100 days for remaining soldiers.

The probability that 2 or fewer students in a class of 30 will be overweight, P(X < 2) is 0.33.

Probability is defined as the ratio of the possible outcomes to the total outcomes of an event. We have, 20% of children are considered overweight.

Total students in a class = 30

We have to determine the probability that 2 or fewer students in a class will be overweight. Using the exponential probability distribution,

P( X= x ) = me⁻ᵐˣ

where, m --> parameter

e --> special math constant and e = 2.73

Now, the probability for X is less than x

P( X < x ) = 1 - e⁻ᵐˣ

here, m = 0.20 , x = 2

The required probability, P(X < 2)

= 1 - e⁻⁽⁰·²⁰⁾²

= 1 - e⁻⁰·⁴⁰

= 1 - 0.670

= 0.33

So, required probability is 0.33.

A: The range of the function f(x) is (-3,∞).

B: The horizontal asymptote for y=2^(x+1)−3 is y=-3, the vertical and horizontal asymptote for y=10/x is x=0 and y=0 respectively.

C: The end behaviour of y=2^(x+1)−3 is [x→∞,x→-∞] = [f(x)→∞,f(x)→-3] and the end behaviour of y=10/x is [x→∞,x→-∞] = [f(x)→0,f(x)→0].

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The set of values of the dependent variable for which a function is defined is known as the range of the function.

The range of an exponential function of the form c·n^(ax+b) + k is f(x) > k.

So, the range of function {2^(x+1)}-3 is f(x)>-3.

The range of function 10/x is (-∞,+∞).

So, the range for system of function becomes (-3,+∞).

The line x=L is a vertical asymptote of the function y=2^(x+1)−3, if the limit of the function (one-sided) at this point is infinite.

In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.

So, find the points where the denominator equals 0 and check them.

As it can be seen, there are no such points, so this function doesn't have vertical asymptotes.

Line y=L is a horizontal asymptote of the function y=f(x), if either limx→∞f(x)=L or limx→−∞f(x)=L, and L is finite.

Calculate the limits -

limx→∞(2x+1−3)=∞

limx→−∞(2x+1−3)=−3

Thus, the horizontal asymptote is y=−3.

The line x=L is a vertical asymptote of the function y=10x, if the limit of the function (one-sided) at this point is infinite.

In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.

So, find the points where the denominator equals 0 and check them.

x=0, check:

limx→0+(10x)=∞

Since the limit is infinite, then x=0 is a vertical asymptote.

Line y=L is a horizontal asymptote of the function y=f(x), if either limx→∞f(x)=L or limx→−∞f(x)=L, and L is finite.

Calculate the limits:

limx→∞(10x)=0

limx→−∞(10x)=0

Thus, the horizontal asymptote is y=0.

The end behaviour of a function f(x) describes the behaviour of the function as x approaches +∞ and x approaches -∞.

The end behaviour of y=2^(x+1)−3 is as x approaches +∞, f(x) approaches +∞ and x approaches -∞, f(x) approaches -3.

The end behaviour of y=10/x is as x approaches +∞, f(x) approaches 0 and x approaches -∞, f(x) approaches 0.

Therefore, the range, asymptotes and end behaviour is found.

The graph of a logarithmic function is first distinguished by the fact that it passes through (1,0).

In the 17th century, Scottish mathematician John Napier (1550-1617) developed logarithms as a tool for computing. From the Greek terms for ratio (logos) and number, he constructed the phrase (arithmos).

A logarithmic function is an exponential function's inverse. Recall that switching the x and y positions yields the inverse of a function. This corresponds to the graph's y=x line. The exponential curve reflects the logarithmic curve, as shown in the graph to the right.

The pH can be calculated using the equation pH = –log(H+), where H+ is the hydronium ion concentration.

If the pH level is 2.5, we can calculate the hydronium ion concentration by rearranging the equation:

H+ = 10^(-pH)

H+ = 10^(-2.5)

H+ = 3.162 x 10^-3 (Option A)

Therefore, the hydronium ion concentration of the vinegar is 3.162 x 10^-3.

Answer:

The pH can be calculated using the equation pH = –log(H+), where H+ is the hydronium ion concentration. To find the hydronium ion concentration of a particular vinegar if the pH level is 2.5, we can rearrange this equation to solve for H+:

H+ = 10^-pH

So, if the pH level is 2.5, we can plug in this value into the equation to find the hydronium ion concentration:

H+ = 10^-2.5

H+ = 3.162 x 10^-3

So the hydronium ion concentration of the vinegar is 3.162 x 10^-3.

Option 3.162 x 10^-3 is correct.

Exponential growth function is defined as a function that shows an increase within a population that occurs at the same rate over time. When populations experience doubling or tripling in numbers, can assume the data increases exponentially. We have, a population grows exponentially.

The growth rate of population = 1.55%

Let us assume initial population be "P₀". We have to determine the time ( in years ) will it take the population to double, i.e., excepted value = 2P₀.

As we know, exponential population growth function is, P = P₀ eʳᵗ

where, P ---> total expected population

P₀ --> initial population

r --> population growth rate

t --> time period (in years)

P = 2P₀ , r = 1.55% = 0.0155 , substituting all known values in above formula,

2P₀ = P₀e⁰.⁰¹⁵⁵ᵗ

=> 2 = e⁰.⁰¹⁵⁵ᵗ

Taking natrual logarithm both sides

=> ln 2 = ln (e⁰.⁰¹⁵⁵ᵗ )

=> ln 2 = 0.0155 ×t ln e
