Which is a rational function?

Answer:

Carl buys 132.475 liters of water.

Step-by-step explanation:

Since Carl buys seven 5-gallon jugs of water multiply 7 by 5 to know how many gallons of water Carl bought in total.

7(5) = 35 Gallons

Now that you have the total amount of gallons of water Carl bought you have to convert 35 gallons to liters given that 1 gallon = 3.785 liters by multiplying 35 by 3.785.

35(3.785) = 132.475

So Carl bought 132.475 liters of water.

Though that is the answer based on what is given a gallon is actually equal to 3.78541 liters so the exact answer would be 132.489 liters of water.

dp/dt = 0.02P-N

Step-by-step explanation:

[tex]\frac{p(t+t)}{nt}[/tex]

The differential equation that describes the relationship between P and t is:

dP/dt = rP - N

where P is the balance in dollars, t is time in years, r is the annual interest rate, and N is the rate of withdrawals in dollars per year.

A differential equation is an equation that relates an unknown function to its derivatives (or differentials) with respect to one or more independent variables. In other words, it is an equation that involves derivatives of an unknown function.

The rate of change of the balance P in the bank account is equal to the difference between the rate of interest earned on the account and the rate at which money is withdrawn from the account.

The rate of interest earned on the account is given by the continuous compounding formula:

dP/dt = rP

where r is the annual interest rate, P is the balance in dollars, and dP/dt is the rate of change of P with respect to time.

On the other hand, the rate at which money is withdrawn from the account is given by the expression:

dN/dt = N/T

where N is the rate of withdrawals in dollars per year, and T is the time interval in years between withdrawals.

If we assume that Ana withdraws money from the account continuously at a rate of N dollars per year, we can write:

N = dN/dt

Substituting this into the first equation, we get:

dP/dt = rP - dN/dt

Substituting the expression for dN/dt, we get:

dP/dt = rP - N/T

Simplifying, we get:

dP/dt = rP - N

which is the differential equation that describes the relationship between P and t.

The differential equation

dP/dt = rP - N

Answer:

x = 21.06 units

Step-by-step explanation:

Given that,

Base, b = 20

Height, h = x

Angle = 36

We need to find the value of x. Trigonometric formulas are used to solve such problems such that,

[tex]\tan(36)=\dfrac{x}{29}\\\\x=29\times \tan(36)\\\\x=21.06[/tex]

So, the value of x is equal to 21.06 units.

Answer:

x = -1, y = 0=9

Step-by-step explanation:

Multiply the second equation by 7 and subtract the two.

14 x + 5 y = 31

- (14 x - 21 y = -203)

This gives 26 y = 234. Divide both sides by 26. y = 9

Then substitute y into any equation. I'll use

 2 x - 3 y = -29

2 x -3(9) = -29

 2 x - 27 = -29

         2 x = -2

           x = -1

Well, ( − 4) 2 − 28 = 8 has two solutions because (-4) -w = 8 = ? once determined - 4 would equal 20 + the left over which is 8. This can be solved multiple ways and even backwards.

For the the equation (-4)² - 28 = 8 the solutions are x = 2 and x = -10.

Two or more expressions with an Equal sign is called as Equation.

The equation (-4)² - 28 = 8 has two solutions because when we square -4, we get 16.

When we subtract 28 from 16, we get -12.

But if we add 28 to -12, we get 16 again.

So we have two values of x that satisfy the equation: x = -4 and x = 4.

b. We can solve the equation by adding 28 to both sides:

(-4)² - 28 + 28 = 8 + 28

Simplifying, we get:

(-4)²= 36

Taking the square root of both sides, we get:

-4 = ±6

So the two solutions are:

x = -4 + 6 = 2

x = -4 - 6 = -10

Therefore, the solutions to the equation (-4)² - 28 = 8 are x = 2 and x = -10.

Suppose that

H subscript o : mu less or equal than 0.01

H subscript alpha : mu greater than 0.01

The value 0.01 is the maximum safe level of some naturally occurring lethal pollutant in drinking water for human consumption. You need to decide if you will use water coming from a specific source for one of the beverages your company produces, based on sample measures of this pollutant taken in random different locations and times at the source of water. In this case you would want to _____.

A. maximize the power of the test

B. maximize beta

C. minimize mu

D. maximize the significance, alpha

E. maximize 1 minus alpha

Answer:

In this case you would want to _____.

D. maximize the significance, alpha

Step-by-step explanation:

The alpha (α) denotes the significance level or the probability of rejecting the initial or null hypothesis when it is true.

A higher alpha (α) reduces the probability of committing a Type II error or not rejecting the null hypothesis. On the other hand, a higher alpha (α) makes it more probable to  reject a null hypothesis when it is true (Type I error).

Answer:

$118.25

Step-by-step explanation:

Always convert the percentage to a decimal by moving the decimal two points to the right/dividing by 100. So 7.5 % = 0.075

110 x 0.075 = 8.25 (the amount of tax added)

110 + 8.25 = 118.25

You can also multiply 110 by 1.075, where the "1" is the $110 and the ".075" is the tax, and save the step of adding. 110 x 1.075 = 118.25

6k = 6000m

Time = distance / rate.

20/6 = 3.33333333 = 3hr + ( 0.33 x 60 = 19.8) - 3.20hr
