Find the distance between points P(3, 4) and Q(4, -6) If necessary round to the nearest hundredth.
Andrei [34K]

Answer:

10.05 units

Step-by-step explanation:

We can find the distance between these points using the distance formula. The distance formula is:

\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

We know that x1 is 3, x2 is 4, y1 is 4, and y2 is -6, so we can substitute inside the equation.

\sqrt{(4 - 3)^2 + (-6 - 4)^2} \\\\\sqrt{1^2 + -10^2} \\\\\sqrt{1 + 100} \\\\\sqrt{101} \\\\\approx10.05

Hope this helped!

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
cricket20 [7]
  To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag) 
5/25 x 100% (because you're trying to find probability of red) 
= 20% 

2) 5 + 8 = 13 (# of red AND blue) 
13/25 x 100% (divide out of the total) 
=52% 

3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green) 
0.2 x 0.48 x 100% 
= 9.6% 

4) 10 + 12 + 28 = 50 (to find total number of trials) 
28/50 x 100% 
= 56% 

5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner) 
= 35</span><span>Its B 20%

Use the rules of exponents to evaluate or simplify.write without negative exponents. 1/4^-2=?
Talja [164]

9514 1404 393

Answer:

  4² = 16

Step-by-step explanation:

The applicable rule of exponents is ...

  1/a^-b = a^b

So, ...

 \dfrac{1}{4^{-2}}=\boxed{4^2 = 16}

_____

<em>Additional comment</em>

If you were to evaluate this using the Order of Operations, you would evaluate the exponent first:

  1/4^-2 = 1/(1/16)

Then, you would do the division.

 1/(1/16) = 16

__

We sometimes find it convenient to manipulate exponential terms to the form with the smallest positive exponents before we begin the evaluation.
