Answer:
It looks like ur doing complex conjugates sooooo the answer is 21 - 12i
They way you show work is
(3-4i)(1+5i) - (2-i) <—— use foil method on first 2 parentheses
= 3 + 11i - 20i ^2 - 2 + i ( remember i^2 = -1)
= 3 + 11i + 20 -2 + i
= 21 + 12i
Answer:
The correct option is A. Real number from 0 to 11
Step-by-step explanation:
Domain is defined as the all possible values of the variable x for which the function is defined.
Now, for the given graph the x-axis represents the time in seconds.
So, we need to find all the possible values of time for which the distance is covered or for which the function is defined.
Given that : The sprinter ran a race in 11 seconds.
And the initial time is 0 seconds
So, The value of t lies between 0 to 11
Thus, Domain : All real numbers 0 to 11
Therefore, The correct option is A. Real number from 0 to 11
Answer:
Its the last option
y = 1488.33x + 23800 ; $172,600.
Step-by-step explanation:
The slope of the trend line = (median value for 2000 - median value for 1940) / 60
= 89300 / 60
= 1488.33.
So the equation is 1488.33x + 23,800
Estimate for 2040
is 1483.33* 100 + 23800
= 172,600.
