Ineed the answer i also will mark brainiest on the coordinate plane shown below, points h and f have coordinates (-2,-3) and (-4,2), respectively. use the distance formula to determine the straight line distance between points h and f. in your final answer, include all of your calculations.

5.385164807

or

5.4

Step-by-step explanation:

Use the Distance Formula:

First, do (-4 - -2) exponent 2 + (2 - -3) exponent 2.

So you get: (-2) exponent 2 + (5) exponent 2.

Then, you do -2 times -2, since there is 2 as an exponent. You also do 5 times 5.

So you get: 4 + 25

Next, you add 4 + 25 and get 29.

Finally, you find the square root of 29, which is 5.385164807, or you can round it.

( I hope that is not too confusing. I couldn't do the exponents, so I just wrote it as a word. The whole thing was done with the Distance Formula.)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
