Task 8: Midpoints and Endpoints: Point B is the midpoint of
AC.
Point Y is the midpoint of
XZ.
B is at (4,-2) and C is at (9,
o).
X is at (-2, 7) and Z is at (-5,
-3).
What are the coordinates of What are the coordinates of
A?
Y?
Point Al
Point Y

no not all of them.

step-by-step explanation:

some of them have a square base.

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.
