Answer:
k = 4 + 5.10i , 4 - 5.10i
Step-by-step explanation:
8k - k^2 = 42
k^2 - 8k + 42 = 0
Completing the square:-
(k - 4)^2 - 16 +42 = 0
(k - 4)^2 = -26
k- 4 = +/-sqrt26
k = 4 + sqrt26 or 4 - sqrt26
k = 4 + 5.10i , 4 - 5.10i
Answer: 4,756 is rounded up to 5,000 when it says round to the nearest thousand
Step-by-step explanation:
anywhere from 4,500 and above is going up but anywhere from 4,400 and lower is going down
Answer:
this is the return on an investment that does not include the taxes the investor must pay on this return
The slope is rise/run
rise=up and down
run=left and right
the rise is 0
the run is inifnity
so 0/inifnity=0
the slope is 0
Answer:
-4/5
Step-by-step explanation:
Lets put the equation in slope intercept form
4x+5y = -20
Subtract 4x from each side
4x-4x+5y = -4x-20
5y = -4x-20
Divide each side by 5
5y/5 = -4x/5 -20/5
y = -4/5 x -4
The equation is in the form y = mx+b where m is the slope and b is the y intercept
the slope is -4/5 and the y intercept is -4
