Answer:
i4=1
Step-by-step explanation:
Explanation: Rewrite i14 as (i4)3×i2 . If i=√−1, then i2=−1 . From here (i2)2=(−1)2 , so i4=1
Answer:
yes
Step-by-step explanation:
yoooooooooooooooooooo
Answer:
(20,0)
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
(-5,-5).....x1 = -5 and y1 = -5
(10,-2)...x2 = 10 and y2 = -2
slope = (-2 - (-5) / (10- (-5) = (-2 + 5) / (10 + 5) = 3/15 = 1/5
y = mx + b
slope(m) = 1/5
use either point, I will use (10,-2)...x = 10 and y = -2
now we sub
-2 = 1/5(10) + b
-2 = 2 + b
-2 - 2 = b
-4 = b
so the equation for this line is : y = 1/5x - 4
to find the x intercept, sub in 0 for y and solve for x
y = 1/5x - 4
0 = 1/5x - 4
-1/5x = -4
x = -4 * -5
x = 20.......so ur x intercept is (20,0) <====
Answer:
3 hours 36min
Step-by-step explanation:
In 1 hour,
Cory can complete 1/9 of the project
Lynn cna complete 1/6 of the project
Total: 1/9 + 1/6 = 5/18
time taken to complete the project together = 18/18 / 5/18 = 18/5 = 3 3/5 hours
3/5 hours = 36/60 hours = 36minutes
therefore, 3hours 36mins
