Which expression is equivalent to (10x)^-3?
kolbaska11 [484]
(10x)^ (-3)
= 1/ [(10x)^3]
= 1/ [10^3* x^3]
= 1/ (1000x^3)

The final answer is 1/ (1000x^3), and I don't think there is a correct option to choose from. ( option c would be correct if it were written with round brackets)

Hope this helps~

Please help me with this homework
Kipish [7]

Answer:

See screenshot below

Step-by-step explanation:

Yes Bus Column:

  1. We need to find an answer for the "no taxi" section. And we have the total and the "yes taxi" section. So, the "yes taxi" section + the "no taxi" section gives you the total. Another way of saying this is total - "yes taxi"  = "no taxi"
  2. 125 - 30 = 95

No Bus Column:

  1. We need to find the total of the "yes taxi" section and the "no taxi" section. So, if we add those two sections together, we'll get the total
  2. 90 + 185 = 275

Total column:

  1. So, this column is really simple to fill out. All we're doing it adding our answers above to get one answer in each section.
  2. "Yes Taxi" section: 30 + 90 = 120
  3. "No Taxi" section: 280
  4. Total section: 125 + 275 = 400
  5. We could have also done the total section by adding together 120 and 280, but we would get the same answer, anyway.

I hope this helps!

Which ordered pairs do not belong to a linear function in the form below?
Semenov [28]

Answer:

  B.  (0, 1); (1, 2); (2,5)

Step-by-step explanation:

All of the given answer choices have x-values that are sequential. A linear function will have y-values that are also evenly spaced.

  A: 0-1 = -1, -1-0 = -1 . . . . differences are the same

  B: 2-1 = 1, 5-2 - 3 . . .  . . differences are not the same, not a linear function

  C: 2-5 = -3, -1-2 = -3 . . . . differences are the same

  D: 1-1 = 0, 1-1 = 0 . . . . differences are the same

Solve using identities​
jeka57 [31]

Answer:

Solution given

Cos\displaystyle \theta_{1}=\frac{13}{15}

consider Pythagorean theorem

\bold{Sin²\theta+Cos²\theta=1}

Subtracting Cos²\thetaboth side

\displaystyle Sin²\theta=1-Cos²\theta

doing square root on both side we get

Sin\theta=\sqrt{1-Cos²\theta}

Similarly

Sin\theta_{1}=\sqrt{1-Cos²\theta_{1}}

Substituting value of Cos\theta_{1}

we get

Sin\theta_{1}=\sqrt{1-(\frac{-13}{15})²}

Solving numerical

Sin\theta_{1}=\sqrt{1-(\frac{169}{225})}

Sin\theta_{1}=\sqrt{\frac{56}{225}}

Sin\theta_{1}=\frac{\sqrt{56}}{\sqrt{225}}

Sin\theta_{1}=\frac{\sqrt{2*2*14}}{\sqrt{15*15}}

Sin\theta_{1}=\frac{2\sqrt{14}}{15}

Since

In III quadrant sin angle is negative

<h3>\bold{Sin\theta_{1}=-\frac{2\sqrt{14}}{15}}</h3>
