Answer:
a=9.641, b=11.49
Vector will be 9.641 i + 11.49 j
Step-by-step explanation:
We have given that vector V has the magnitude of 15
And it makes an angle of 50
with positive x axis
Now let the x component of vector V is a and y component of vector V is b
So 

In vector form 9.641 i+11.49 j
Answer:
if it says greatest change then its 6:30 to 7:00
Step-by-step explanation:
Given the statement, "If

is odd, then

is odd," its contrapositive claims that, "If

is not odd, then

is not odd."
So assume

is not odd, i.e.

is even. This means there is an integer

for which

. Squaring this gives

.
Well, we can write

, and

is just another integer, which means

must be even.
