Part A = 6 inch (To the nearest whole of an inch)

Part B = 5.6 Inch (To the nearest tenth of an inch)

As given in the question,

Area of square poster = 31 sq. inches

Let 'l' be the length of the square poster

Now according to formula

Area of square poster = Length * Length

Substitute the values in the formula we get,

31 = l × l

⇒ l² = 31

⇒ l = √31

⇒ l = 5.568

Length = 5.568

Hence, the length of one side of the poster, when the area of a square poster is 31 square inches is

Part A = 6 inch (To the nearest whole of an inch)

Part B = 5.6 Inch (To the nearest tenth of an inch)

We are spending $ 0.0263 less every Mello Yello can, therefore it is  the better buy.

What is profit and loss?
Subtract the smaller value from the greater value in order to calculate the profit or loss. The selling price is always higher than the cost price when there is a profit. Selling price minus cost price is profit. In a loss scenario, the cost price is higher than the selling price. Loss = Price Cost

Given,
20 cans of Mello Yello for $4.75
Therefore cost of 1 can of Mello Yello = $4.75 / 20 = $ 0.2375

Also given,
36 cans of Sprite for $9.50
Therefore, cost of 1 can of Sprite  = $9.50 / 36 = $ 0.2638
Therefore, per can we are paying $ 0.0263 less for Mello Yello.

We need to know about scientific notation to solve this problem. The number of seconds the playlist will play is 3.99 x 10^5.

Expressing a number in scientific notation means writing the number as a multiple of ten with ten raised to some power. We use scientific notation for numbers that are very small or very big. When writing numbers in scientific notation we always have one number other than zero before the decimal point. In this question we know that there are 1900 songs and each song has average time of 3.5 minutes, we need to convert the minutes into seconds and multiply the number of seconds of each song to 1900.

1 min=60 seconds

3.5 mins=3.5 x 60=210 seconds

210 x1900=399000 seconds

399000=3.99 x 10^5

Therefore the number of seconds that the playlist will play is 3.99x 10^5

The operation of forming Cartesian products is not commutative because part of the definition of a Cartesian product is the order of the elements generated by the two sets.

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

Explanation:

Let's go over an example. We'll have these two sets

A = {1,2}

B = {3,4}

The cartesian product is this set of ordered pairs

A x B= {(1,3), (1,4), (2,3), (2,4)}

Each (x,y) pair has x as a value from the first set mentioned (A), and y a value from the second set mentioned (B). It might help to make a 2 by 2 table.

If we swap the order of set A and B then we have

B x A = {(3,1), (4,1), (3,2), (4,2)}

We can see that A x B does not equal B x A in this case. Therefore, the cartesian product operation is not commutative. The order matters.

Side note: Two sets are equal when they are subsets of each other.

Answer:

2x (2x³ + 1)

Step-by-step explanation:

To get the answer factor 2x^1 / 2x of ( 4x^4 + 2x )

When you factor an expression, you are looking for a number which can perfectly divide into another number.

Remember that the numerical timetable states that (2 x 2 = 4).

And we already know that (2 divided by 4 = 2), as well as, that any rational number divided by itself is equal to 1

Therefore the value 2x is divisible by itself and is also divisible by 4x^4 exactly two times

Note: the reason why (4x^4 ÷ 2x ) becomes (2x³), is that you have to subtract the exponents of each term from each other after you finish dividing.  So ( X^4 - X^1 = X^3) -

The lake is 12,250 feets deep.

The elevation is changing in the downward direction and at a rate of -11ft/s.

So it means that the downward velocity of the probe is 11ft/s.

The value of downward acceleration is 9.8?m/s² which is equal to acceleration due to gravity.

The total time taken to reach down is 50seconds.

We can use the equation of motion because the acceleration is constant,

Using,

S = ut + 1/2at²

Where,

S is the depth of the pool,

U is initial velocity,

U is zero because the probe is dropped.

S = 1/2at²

The answer to the given question is option A that is only the first equation is an identity.

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions.

There are numerous distinctive trigonometric identities that relate a triangle's side length and angle. Only the right-angle triangle is consistent with the trigonometric identities.

Sin θ = 1/Csc θ or Csc θ = 1/Sin θ

Cos θ = 1/Sec θ or Sec θ = 1/Cos θ

Tan θ = 1/Cot θ or Cot θ = 1/Tan θ

1) LHS : 8 sec θ sin θ = 8 X 1/ cos θ X sin θ = 8 tan θ

RHS : 8 X sin^2 θ/ cos^2θ X cosθ / sin θ = 8 tan θ

Thus LHS = RHS and it is given above so 1st equation is an identity.

2) LHS:  11 X cot^2 θ/ cosec θ X sec^2 θ = 11 cos^2θ /sin θ

and RHS : 11 cosec^2 θ

since LHS ≠ RHS because the second equation us not an identity.

A rectangle has two pairs of opposite sides that are of equal length, one pair is the length, while the other is the width.

The area of a rectangle = the product of its length and its width = (length)(width).

The area of the shaded region = area of the larger rectangle - area of the smaller rectangle

Dimensions of the larger rectangle:

Length of the larger rectangle = 10 + 2 = 12 units

Width of the larger rectangle = 9 + 2 = 11 units

Area of the larger rectangle = (12)(11) = 132 units²

Now, from the graph, the parts above the horizontal line represents profit, while the part below the horizontal line represents loss.

(a) Maximum profits are earned when there are 4 clerks working.

From the graph, we can see that this statement is CORRECT. The maximum profit is at 400 thousand dollars and takes place at 4 on the horizontal axis, this 4 represents 4 clerks working

(b) The store earns profits when no clerks are working.

No clerks are working when we consider 0 on the horizontal plane. From the picture above, tracing 0, it shows us something below the horizontal line which represents loss. So, this statement is INCORRECT. When no clerks work, there is a loss not profit

(c) Maximum profits are earned when there are 7 clerks working.

Tracing 7 from the graph, it doesn't fall on the top part of the curve which indicates maximum profit. Hence, this statement is INCORRECT.

d) The store earns about $400,000 in profits on its best days.

From the image above, we can see that this is correct.

(e) The store loses money when 8 or more clerks are working.

When we traced 8 from the horizontal line, it fell to the part of the graph which indicated loss.
