D. 4s²

Step-by-step explanation:

There are 4 equal spaces that the square court yard room is divided to.

Area of a square = s², where s is the side Length.

Therefore,:

Area of 1 space = s²

Total area of the square courtyard room = area of the 4 spaces = 4(s²) = 4s²

D. 4s² is the expression for the total area of the courtyard.

Answer:

4s² is the expression for the total area of the courtyard.

Hi! I'd be happy to help you. However, there is not enough information here for us to help, as there is no way to tell which graph is correct without the equations of f(x) and g(x). They'd look something like:

"f(x) = x-2," or "g(x) = 7x+3."

Are you able to provide the equations of of f(x) and g(x)? I would be more than happy to help.

----------------------------------------------------------------------------------------------------------------

UPDATE: I did not realize that you could solve this problem without the original equations. Please refer to the other user's response for an amazing and detailed explanation of this problem! :)

Answer:

The first graph.

Step-by-step explanation:

We want to find the graph that shows:

[tex]h(x)=f(x)g(x)[/tex]

Notice that g(x) is a line and f(x) is a quadratic.

So, their product must be a cubic.

Also, g(x) and f(x) is the same across all four graphs. The only difference is h(x).

Notice that our quadratic f(x) is curving upwards. Therefore, the leading coefficient of f(x) is positive.

Notice that the line g(x) is sloping downwards. Therefore, the leading coefficient of g(x) is negative.

So, this means that the leading coefficient of our cubic h(x) must be negative since a positive times a negative yields a negative.

Remember that the parent cubic function has a positive leading coefficient and it rises from left to right.

So, if our leading coefficient is negative, the cubic will fall from left to right.

Therefore, we can eliminate the 2nd and 3rd graphs since in those two, h(x) has a positive leading coefficient.

Now, we can just pick a test point and determine whether our graph is the first or the fourth.

Let's let x = -2. So, we have the equation:

[tex]h(x)=f(x)g(x)[/tex]

Substitute all Xs for -2s:

[tex]h(-2)=f(-2)g(-2)[/tex]

Looking at the graphs, we can see that f(-2) is 8. g(-2) is 0.5. Substituting this back, we get:

[tex]h(-2)=8(.5)=4[/tex]

So, h(-2) should be 4.

For the first graph, h(-2) is indeed 4.

For the second graph, h(-2) is 6.

So, the correct graph that represents f(x)g(x) is the first graph.

And we're done!

Given:

[tex]\dfrac{\sin (x)}{1-\cos ^2 (x)}\tan \left(\dfrac{x}{2}\right)[/tex].

To find:

The expression, which is equivalent to the given expression.

Solution:

We have,

[tex]\dfrac{\sin (x)}{1-\cos ^2 (x)}\tan \left(\dfrac{x}{2}\right)[/tex]

[tex]=\dfrac{\sin (x)}{1^2-\cos ^2 (x)}\times \dfrac{1-\cos (x)}{\sin (x)}[/tex]         [tex][\because \tan \left(\dfrac{x}{2}\right)=\dfrac{1-\cos (x)}{\sin (x)}][/tex]

[tex]=\dfrac{\sin (x)}{(1-\cos (x))(1+\cos (x))}\times \dfrac{1-\cos (x)}{\sin (x)}[/tex]         [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

Cancel out the common factors.

[tex]=\dfrac{1}{1+\cos (x)}[/tex]

Therefore, the correct option is C.

    Given question is incomplete; find the complete question in the attachment.

    Simplified form of the given trigonometric expression will be represented by Option C.

Given expression is,

[tex][\frac{\text{sin(x)}}{1-\text{cos}^2(x)}]\tan(\frac{x}{2} )=\frac{\text{sin(x)}}{1-\text{cos}^2(x)}\times \frac{1-\text{cos}x}{\text{sinx}}[/tex] [Since. [tex]\text{tan}\frac{x}{2} =\frac{1-\text{cosx}}{sinx}[/tex]]

                          [tex]=\frac{1-\text{cos}x}{(1-\text{cosx})(1+\text{cosx})}[/tex]

                          [tex]=\frac{1}{1+\text{cosx}}[/tex]

   Therefore, Option C will be the correct option.

Answer:

  3 significant digits

Step-by-step explanation:

If there is a decimal point with non-zero digits to its left, all digits to the right of the left-most non-zero digit are significant. Here, that is all of them. This number has 3 significant digits.

__

Comment on other cases

If there is no decimal point, the digits between any leading and trailing zeros are significant. For example, 02000 has 1 significant digit.

If there are no non-zero digits left of the decimal point. All digits except leading zeros are significant. 0.0031000 has 5 significant digits.

Answer:

The indifference point is 20 gallons.

Step-by-step explanation:

Giving the following information:

Quik-Clean Car Wash:

$15 for a car wash plus $2.50 per gallon for unleaded gasoline.

Mighty Clean Car Wash:

$10 for a carwash plus $2.75 per for unleaded gasoline.

First, we need to structure the total cost formula:

Quik-Clean= 15 + 2.5x

Mighty Clean= 10 + 2.75x

x= gallon of gasoline

Now, we equal both formulas and isolate x:

15 + 2.5x = 10 + 2.75x

5 = 0.25x

20 = x

The indifference point is 20 gallons.

Prove:

Quik-Clean= 15 + 2.5*20= $65

Mighty Clean= 10 + 2.75*20= $65

C. x - y = 0

Step-by-step explanation:

Step 1: find the slope (m) and y-intercept (b) of the graphed line.

Using the two points on the line (0, 0) and (2, 2),

Slope = [tex] \frac{rise}{run} = \frac{2 - 0}{2 - 0} = \frac{2}{2} = 1 [/tex]

The y-intercept (b) is the point at which the line intercepts the y-axis. Therefore, the y-intercept (b) = 0

Step 2: Generate an equation for the line in slope-intercept form using b = 0 and m = 1.

Substitute m = 1 and b = 0 into y = mx + b

y = 1(x) + 0

y = x

Step 3: rewrite the equation from slope-intercept form to standard form.

To express I'm standard form, take all terms with coefficient to the left, and leave the constant on the right side of the equation.

y = x

Subtract y from both sides

y - y = x - y

0 = x - y

x - y = 0
