Vector QP= (-5+6, 11-4) = (1, 7)
its magnitude is QP= sqrt( 1 + 49)= sqrt (50)=5sqrt2
The domain of the function will be [-4, 6). Then the correct option is B.
The complete question is attached below.
<h3>What are domain and range?</h3>
The domain means all the possible values of x and the range means all the possible values of y.
The function is given below.

Then the domain of the function will be [-4, 6).
Then the correct option is B.
More about the domain and range link is given below.

Y(y+21) If you think about it you will see that it would most likely be this answer because the product of something is multiplying, and the sum is adding. If this answer is not correct then I am sorry.
Let Micaela be M
Let Sam be S
M = 2 + S
In 4 years, their ages will be 40 in all
Subtract 8 (because it is 2 people) from 40
40 - 8 = 32
then use 32 to find their ages.
M = 2 + S
S
32 - 2 = 30
30/2 = 15
Sam is 15
Micaela is 15 + 2, or 17
Sam is 15, Micaela is 17
hope this helps
