Aubrey filled her pool 0.9 of the way with water. Water evaporated from the pool at a rate of 7.5ft ^ 3 per day.

Answers

Answer: hello your question lacks vital data hence I will provide you with a general equation within the scope of your question

answer :

General equation = ( Stiver and Mackay or EPA ) evaporation equations

E = [tex]\frac{PAW}{T +459.67}[/tex]  or  E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]

Step-by-step explanation:

Given data

volume of water in pool = 0.9 i.e. 90% full

rate of evaporation = 7.5ft^3  per day = 56.1039 gallons / day

Assumption :

Volume of pool = 16,000 gallons

In order to resolve the missing part of the problem  apply the equation below

E = [tex]\frac{PAW}{T +459.67}[/tex]   or   E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]

where : E = Evaporation rate , P = water's vapor pressure ,  A = pool surface Area , W = wind speed ,  T = Temperature in Fahrenheit

Which greatest digit should replace n so that the number 342n84 is divisible by 3?

Answers

Answer:

9

Step-by-step explanation:

If you want the number to be divisible by three make sure the sum of all the numbers are divisible by three. Add all the numbers you have to see what they make.

3+4+2+8+4=21

So we just need to find the greatest number we can add to that to have it remain divisible by three. A number divisible by three is 30, and we can add 9 to 21 to make 30. Of course, there are other numbers we could add, but nine is the largest one-digit number that would work. Other smaller numbers include 3 and 6.

3+4+2+8+4+9=30

Now we check to see if our number is divisible by three

342984÷3 = 114328

114328 is a whole number so we know it's divisible.

Find the equation of the line passing

Answers

Step-by-step explanation:

1.) Plug in one of the points.

y = 8x + b

6 = 8(4) + b

2.) Solve for b (or [?])

[tex]6 = 32 + b \\ - 32 \: \: \: \: \: \: \: \: \: - 32[/tex]

32 cancels out on the right side.

Subtract 32 from 6, which is -26

3.) -26 = b

4.) Check with other point:

-2 = 8(3) + b

-2 = 24 + b

Cancel out 24 on the right side: 24-24 = 0

-2 - 24 = -26

-26 = b

Which function is graphed below?

Answers

The function whose graph is plotted below is given by: Option B:f(x) = cos(x)

How to find the function which was used to make graph?

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.

The missing graph is attached below.

It is either sine or cosine (as known from the options).

The sin function is 0 at x = 0, so we're sure the function isn't sin or negative sin as 0 would make it fall on 0.

The function is definitely [tex]\cos(x)[/tex] since at x = 0 it is 1 and at x = [tex]\pi[/tex] it is -1 (while if it would be -cos(x), it would be -1 at x =0 and 1 at x = [tex]\pi[/tex] )

Thus, the function whose graph is plotted below is given by: Option B:f(x) = cos(x)

[tex]\cos(\theta)=\frac{4}{5}[/tex]

Step-by-step explanation:

Step 1:

Let us find the missing side. We know this is a right triangle, so we can use the pythagorean thereom to find the last side. Let us set 12 as variable a, 20 as variable c, and the unknown side as variable b.

[tex]a^2+b^2=c^2\\12^2_b^2=20^2\\b^2=400-144\\b^2=256\\b=\pm16[/tex]

We do know that a length can never be negative, so the side b would be 16.

Step 2:

According to SOHCAHTOA, cosine is utilizes the adjacent and hypotenuse of the given angle theta. Let us write the equation:

[tex]\cos(\theta)=\frac{adjacent}{hypotenuse} \\\\\cos(\theta)=\frac{16}{20} \\\\\cos(\theta)=\frac{4}{5}[/tex]

The attendances y for two movies can be modeled by the following equations, where x is the number of days since the movies opened.



y=-x^2+35x+100 Movie A

y=-5x+275 Movie B



When is the attendance for each movie the same?
After ___ days and after ___ days.

Answers

Answer:

After

days and after

days.

By solving a quadratic equation, we will see that the attendance will be the same after 5 days and after 35 days.

When is the attendance for each movie the same?

This will happen for the values of x such that:

y = -x^2 +35x + 100 = y = -5x+275

There says that the attendance for movie A is the same as the one for movie B. So we just need to solve that.

We can write the equation as:

-x^2 +35x + 100 = -5x+275

If we simplify this, we get:

-x^2 + 35x + 100 + 5x - 275 = 0

-x^2 + 40x - 175 = 0

This is a quadratic equation, the two solutions are given by Bhaskara's formula, we will get:

[tex]x = \frac{-40 \pm \sqrt{(40ft)^2 - 4*(-1)*-175)} }{2*-1} \\\\x = \frac{-40 \pm 30}{-2}[/tex]

So the two solutions are:

x = (-40 + 30)/-2 = 5

x = (-40 - 30)/-2 = 35

So, the attendance will be the same after 5 days and after 35 days.
