Find (a) PQ to the nearest tenth and (b) the coordinates of the midpoint of PQ. P(-6,6), Q(4,-1)

a)   PQ = 12.2

b)   M (-1, 2.5)

Step-by-step explanation:

a) PQ

use pythagorean PQ =

PQ = = 12.2

b) Midpoint

Mx = (-6 + 4)/2 = -1

My = (6 + -1)/2 = 2.5

Step-by-step explanation:

We can use Pythagorean theorem to solve for the length of PQ.

The length of PQ is approximately 12.21.

We can find the midpoint with the midpoint formula:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
