A rotation is a isometry, a rigid motion. It preserves length, angles, and parallelism.
Answer:
Since all parts of 2i(-3+7i) is in the denominator, you have to use an extra set of parentheses around the whole denominator. this is what you do
(5+i)(6−5i) / (2i(−3+7i))
= (30−25i+6i−5i^2) / (−6i+14i^2)
= (35−19i) / (−14−6i)
= (35−19i)(−7+3i) / (2(−7−3i)(−7+3i))
= (−245+105i+133i−57i^2) / (2(49−9i^2))
= (−188+238i) / (2(58))
= (−188+238i) / 116
= −47/29 + 119/58 iso that is how you do it
The answer is b are C but I think it’s B hopes this helps
Answer:
P1 = P2 - ma*t
Step-by-step explanation:
ma= P2-P1/t
we multiply by t both sides of the equation
ma*t = (P2 - P1)*t/t
ma*t = P2 - P1
we sum by P1 both sides of the equation:
P1 +ma*t = P2 - P1 +P1
We ave:
P1 + ma*t = P2
we subtract by ma*t both sides of the equation:
P1 + ma*t -ma*t = P2 - ma*t
finally we have:
P1 = P2 - ma*t
