Use order of Operations to simplify the following: 4² - (28÷7) + 111

"R" is the distance from the origin to the point.

R = √(-3² + 7²)

R = √(9 + 49)

R =  √(58)

R = 7.62

tangent (Θ)  =  7 / -3

Θ  =  arctan (7 / -3)

Θ  =  113.2°  counterclockwise from the x-axis

Answer:

The coefficients are

11,-4 and 0.

Step-by-step explanation:

We are given two algebraic expressions. We are subtracting the second from the first.

First one is:

(4x²y3 + 2xy2 - 2y)

Second expression is:

(-7x?y3 + 6xy2 – 2y)

The given expression:

(4x²y3 + 2xy2 - 2y) - (-7x?y3 + 6xy2 – 2y)

The coefficients are

11,-4 and 0.

Answer:

[tex]n^{2}(-3) -8[/tex]

Step-by-step explanation:

So the "product of" means the answer to a multiplication problem. That means -3 is being multiplied by a number which is squared. I used the variable "n" for number but you could use any letter you want.

This is what we have so far,

[tex]n^{2} \\[/tex] x -3 or [tex]n^{2}[/tex](-3)

The term decreased means to reduce or subtract. Which means we are left with....

[tex]n^{2}(-3) -8[/tex]

Hope that helps and have a great day!

4x + 9 = 56

The value of x.

4x + 9 = 56

The value of 9 changes when we take 9 to the Right Hand Side, we get

4x = 56 - 9

Now, The value of 4 changes when we take 4 to the Right Hand Side, we get

x = 47/4

The value of x is 47/4

The required area of tortilla is 16π square inches.

What is an area of a circle?

Area of a circle is defined as the region occupied by the circle in two-dimensional plane.

Mathematically,

                         A = π (d/2)²

where d is the diameter of circle

or,                      A = π r²  

where r is the radius of circle.

Now, given diameter of tortilla is 8inches.

⇒ d  = 8inches

Since,tortilla is a circle

So, area of tortilla A = π (d/2)²

⇒ A = π (8/2)²

⇒ A = π (4)²

⇒ A = 16π square inches

Hence, required tortilla's area is 16π square inches.

x = a number

4(x + 5) = x - 1

Now, let's distribute the 4

4x + 20 = x - 1

Subtract x and 20 from both sides.

3x = -21

Divide both sides by 3

Answer:

$720 in one week

Step-by-step explanation:

40 * 18

$720

Best of Luck!

Answer:

$720

Step-by-step explanation:

The equation set up for this problem is 40x18 because for every one hour Mr. Thompson works, he earns $18.

AR:AB = 1/5 means that AR has length equal to 1/5 of the length of AB.

To find the x coordinate of R, you take 4/5 of the x coordinate of A plus 1/5 of the x coordinate of B:

4/5 * 1 + 1/5 * 4 = 8/5

You do the same for the y coordinate:

4/5 * (-1) + 1/5 * 4 = 0

So the point R has coordinates (8/5, 0).

Answer:

(s+2)^3

Step-by-step explanation:

I think this is referring to a square as a box, so the length of a jewelry box would be s. We learn that a shipping box is 2 inches longer, so s+2 = the length of the shipping box.

Volume = Length*Width*Height, but if square, all dimensions are the same, so s+2 to the power of 3 would be your answer.

Answer:

-12.25

Step-by-step explanation:

Let's investigate what happens when negative values appear under the radical symbol (as the radicand) for cube roots and square roots.

In some situations, negative numbers under a radical symbol are OK. For example, radnegnew14is not a problem since (-2) • (-2) • (-2) = -8, making the answer -2. In cube root problems, it is possible to multiply a negative value times itself three times and get a negative answer.

Difficulties, however, develop when we look at a problem such as radnegnew214. This square root problem is asking for a number multiplied times itself that will give a product (answer) of -16. There simply is no way to multiply a number times itself and get a negative result. Consider: (4) • (4) = 16 and (-4) • (-4) = 16.

CUBE ROOTS:

radnn1

BUT

SQUARE ROOTS:

n2

Yes, (-2) x (-2) x (-2) = -8.

No problem.

Nope!   (4) x (4) ≠ -16.

Nope!   (-4) x (-4) ≠ -16.

bullet Square roots are the culprits! The difficulties arise when you encounter a negative value under a square root. It is not possible to square a value (multiply it times itself) and arrive at a negative value. So, what do we do?

statement

The square root of a negative number does not exist among the set of Real Numbers.

When problems with negatives under a square root first appeared, mathematicians thought that a solution did not exist. They saw equations such as x2 + 1 = 0, and wondered what the solution n3 really meant.

In an effort to address this problem, mathematicians "created" a new number, i, which was referred to as an "imaginary number", since it was not in the set of "Real Numbers". This new number was viewed with much skepticism. The imaginary number first appeared in print in the year 1545.

def The imaginary number "i" is the square root of negative one.

neg i

An imaginary number possesses the unique property that when squared, the result is negative.

irad1

Consider: irad2a

The process of simplifying a radical containing a negative factor is the same as normal radical simplification. The only difference is that the irad4 will be replaced with an "i ".

As research with imaginary numbers continued, it was discovered that they actually filled a gap in mathematics and served a useful purpose. Imaginary numbers are essential to the study of sciences such as electricity, quantum mechanics, vibration analysis, and cartography.

When the imaginary i was combined with the set of Real Numbers, the all encompassing set of Complex Numbers was formed.
