Step-by-step

Division is one of the four fundamental arithmetic operations. Andrew is faster than Noah.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Andre can now complete 135 multiplication facts in 90 seconds.

A.) If Andre is answering questions at a constant rate, then the number of facts that Andre can answer per second can be written as,

Number of facts per seconds = 135 facts / 90 seconds

                                                 = 1.5 facts per seconds

B.) Noah also works at a constant rate, and he can complete 75 facts in 1 minute. Therefore, the number of facts that Noah can answer per second can be written as,

Number of facts per seconds = 75 facts / 60 seconds

                                                 = 1.25 facts per seconds

Now, since the number of facts that Andrew can read in a second is 1.5 facts, while the number of facts that Noah can read in a second is 1.25 facts.

Hence, Andrew is faster than Noah.

Answer:

The answer is 14 :)

Step-by-step explanation:

We have,

Find the measure of ∠ x ?

∠PQR + ∠RQS = ∠PQS

⇒ 76° + x = 90°

⇒ x = 90° - 76°

⇒ x = 14°

Answer: Hi!

So first, I'm going to convert "350 below ground level" to -350, as this is what "below ground level" represents.

Now, we should find the total distance traveled. Take the absolute value of -350 (350) and add it to 10, the metres above ground level. This is 360.

We already know the rate of travel; 6m/min. All we have to do now is divide the total distance (360) by the rate of travel (6)!

360 ÷ 6 = 60

So, it took 60 minutes, or one hour, for the elevator to travel down the shaft!

Explanation:

Answer:

sinθ = -5/√61

secθ = √61/6

tanθ = -5/6

Step-by-step explanation:

From the given coordinate (6, -5), x = 6 and y = -5. This shows that the point lies in the 4th quadrant. In the fourth quadrant, only cos θ is positive, both sin θ and tan θ are negative.

Let us get the value of the radius 'r' first before calculating the trigonometry identities.

Using the Pythagoras theorem;

[tex]r^2 = x^2 + y^2\\r^2 = 6^2 + (-5)^2\\r^2 = 36+25\\r^2 = 61\\r = \sqrt{61}[/tex]

Using SOH, CAH, TOA to get the trigonometry identities;

Given x = 6, y =5 and r = √61

[tex]sin \theta = opp/hyp = y/r\\sin \theta = 5/\sqrt{61} \\[/tex]

Since sin θ, is negative in the fourth quadrant, [tex]sin \theta = -5/\sqrt{61} \\[/tex]

[tex]cos \theta = adj/hyp = x/r\\cos \theta = 6/\sqrt{61} \\[/tex]

[tex]sec \theta = \frac{1}{cos \theta} \\sec \theta = \frac{1}{6/\sqrt{61} } \\sec \theta = \frac{\sqrt{61} }{6}[/tex]

For tanθ:

[tex]tan \theta = \frac{opp}{adj} = \frac{y}{x} \\tan \theta = \frac{5}{6}\\[/tex]

Since tan θ, is negative in the fourth quadrant, [tex]tan \theta = -5/6[/tex]

 [tex]SIN\Theta=\frac{-5}{\sqrt{61} }[/tex],

[tex]SEC\Theta=\frac{\sqrt{61} }{6}[/tex]  

[tex]TAN\Theta=\frac{-5}{6}[/tex].

Given coordinate of point be (6, -5).

So the point lies in the 4th quadrant. In the fourth quadrant, only cos θ is positive, both sin θ and tan θ are negative.

Since (6, -5) is on the terminal side that puts us in the fourth quadrant. If we plot that point and draw a diagonal to it from the origin, we will be able to draw a right triangle with that diagonal as the hypotenuse.That means the adjacent side is 6 and opposite side it -5.

By Pythagorean theorem, we find that the hypotenuse

[tex]H=\sqrt{6^{2} +(-5)^{2} }[/tex]

[tex]H=\sqrt{61}[/tex]

We know from trigonometric ratios,

[tex]SIN\Theta=\frac{Perpendicular}{hypotenuse} \\[/tex]

[tex]SIN\Theta=\frac{5}{\sqrt{61} }[/tex]

Since [tex]SIN\Theta[/tex] is negative in 4th quadrant,

so,

[tex]SIN\Theta=\frac{-5}{\sqrt{61} }[/tex]

Similarly,

[tex]SEC\Theta=\frac{hypotenuse}{base}[/tex]

[tex]SEC\Theta=\frac{\sqrt{61} }{6}[/tex]

And,

[tex]TAN\Theta=\frac{perpendicular}{base}[/tex]

[tex]TAN\Theta=\frac{-5}{6}[/tex]

Hence,  [tex]SIN\Theta=\frac{-5}{\sqrt{61} }[/tex], [tex]SEC\Theta=\frac{\sqrt{61} }{6}[/tex]  and [tex]TAN\Theta=\frac{-5}{6}[/tex].

Complete Question: Which of the following is an example of the difference of two​ squares?

A x² − 9

B x³ − 9

C (x + 9)²

D (x − 9)²

Answer:

A. [tex] x^2 - 9 [/tex].

Step-by-step explanation:

An easy way to spot an expression that is a difference of two squares is to note that the first term and the second term in the expression are both perfect squares. Both terms usually have the negative sign between them.

Thus, difference of two squares takes the following form: [tex] a^2 - b^2 = (a + b)(a - b) [/tex].

a² and b² are perfect squares. Expanding [tex] (a + b)(a - b) [/tex] will give us [tex] a^2 - b^2 [/tex].

Answer:

the simple multiplier is equal to 4

Step-by-step explanation:

In an economic model,

Y=  C + I + G + (X - M)

the average expenditure Y must be equal  to the totality of the output

If C = 3 + 0.75Y

where;

marginal propensity to consume MPC = 0.75

Then,

Y = 3 + 0.75Y + 2 + 1

Y = 6+0.75 Y

Y - 0.75 Y = 6

0.25 Y = 6

Y = 6/0.25

Y = 24

However,  the simple multiplier can be expressed as:

[tex]=\dfrac{1}{1 - MPC}[/tex]

[tex]=\dfrac{1}{1 - 0.75}[/tex]

[tex]=\dfrac{1}{0.25}[/tex]

= 4

Answer:

The original number is -7.

Step-by-step explanation:

In this section, we are trying to figure out a mysterious number. Let's call this number y. To find the value of y, we need to create an equation. Our equation will be based on clues hidden in the text. So, what do we know?

- A number, aka y, is increased by 3. (y+3)

-That number is doubled. 'That number' refers to the answer of y+3. So, (y+3)x2.

-Finally, the end result is -8.

Great! Now we know our equation: 2(y+3)=-8. We need to figure out what y equals, so let's isolate the y term with some algebra.

2(y+3)=-8; Original formula

2y+6=-8; Distribute the (y+3)

2y=-14; Carry the 6 to the other side of the equation.

y=-7: Divide

Thus, our mysterious number is -7. Hope this helps:)))

Step-by-step explanation:

first find the value of N

Hello,

First of all, dividing by 0 is not defined we will take x different from 1/3 (because -1+3x= 0 <=> x = 1/3)

Then, dividing this polynomial by (-1+3x) means that you have to have Q(x), a polynomial of degree 1 and R a real number such that

[tex]\dfrac{9x^2-6x+2}{-1+3x}=Q(x)+\dfrac{R}{-1+3x}\\\\\text{We can multiply by (-1+3x)}\\\\9x^2-6x+2=(-1+3x)Q(x)+R[/tex]

Either you do the division and you can select the correct answer or you check the different answer to identify the correct one.

For instance, for the first answer, let's estimate

[tex](-1+3x)(3x-3)+\dfrac{-1+3x}{3x-1}\\\\=-3x+3+9x^2-9x+1\\\\=9x^2-12x+4[/tex]

and this is not equal to our initial polynomial, so this is not the correct answer.

Second Answer.

[tex](-1+3x)(3x-1)+\dfrac{-1+3x}{3x-1}\\\\=-3x+1+9x^2-3x+1\\\\=9x^2-6x+2[/tex]

And this is our initial polynomial. So this is the [tex]\large \boxed{\sf \bf \text{correct answer}}[/tex]

Thank you.

PS: in this example, you can even notice the following (so it makes the division trivial)

[tex](3x-1)^x=9x^2-6x+1 \\\\\text{So}\\\\9x^2-6x+2= (3x-1)^2+1\\\\\text{And, then.}\\\\\dfrac{9x^2-6x+2}{-1+3x}=3x-1+\dfrac{1}{3x-1}[/tex]
