P(perfect square) is even
Answer:
A
Step-by-step explanation:
z = -3 - 5i
z (i) = i (-3 - 5 i)
z (i) = -3i - 5i^2
z (i) = -3i - 5 (-1)
z (i) = -3i + 5
z (i) = 5 - 3i
Therefore, letter A is the correct answer.
9423
three goes into nine three times
which gives you zero then bring the four down
three goes into four one time then subtract four from three then that gives you one than bring the two down which makes twelve and three goes into twelve four times and 12 subtracted from twelve gives zero and then bring the three down and three goes into three 1 time so that equal zero
so in total the whole answer should be 3141
Answer with explanation:
The given trigonometric Function is,
y= cos x
→The maximum value of , cos x , is 1, at x=0 degree.
Cos x =1
→Cos x = Cos (0)degree,

→ for, k= An Integer
x=2 k π→→General formula that gives the x-coordinates of the maximum values for y = cos(x)
Ordered Pair =(x,y)=(2 k π, 1)
For, any value of , k in the given equation, y will be always 1.
The sum of angles of a triangle is 180°.
48 +(6x -28) +2x = 180
8x +20 = 180
8x = 160
x = 20
∠B = (6x -28)° = (6*20 -28)° = 92°
∠C = 2x° = 40°
___
x = 20
∠B = 92°
∠C = 40°
