C: 20 m/s
Explanation:
Distance run: 1000m
Time passed: 50s
Distance divided by time equals speed.
1000m / 50s = 20 m/s
( 8 - 2i ) * ( 5 + i ) = 40 + 8i - 10i - 2* i^2 = 40 -2i - 2 * ( -1 ) = 40 + 2 - 2i = 42 - 2i;
THE ANSWER IS D. 42 - 2i

Answer:
4√2x.
Step-by-step explanation:
√32 = √2*√16 = 4√2.
√x^2 = x.
Answer:
x = 
Step-by-step explanation:
Data provided:
ln(x) − ln(y) = 2a
Now,
The using the following properties of log function,
we have
log(A) - log(B) = 
and,
ln(a) = b is equivalent to a = 
(here e is exponential )
ln(e) = 1
therefore,
the above equation transforms as:
= 2a
taking anti-ln both sides,
we get
= 
or
x =
