Given y=5x−3 with the domain D: {−2, −1, 0, 1, 2}, fill in the missing values of the table below.
spayn [35]

Answer:

see below

Step-by-step explanation:

y = 5x-3

Let x = -2  y = 5(-2) -3 = -10 -3= -13

Let x = -1  y = 5(-1) -3 = -5-3 = -8

Let x = 0   y = 5(0) -3 = 0-3 = -3

Let x = 1     y = 5(1) -3 = 5-3 = 2

Let x = 2   y = 5(2) -3 =10-3 = 7

Maddie converts z = 8(cos(300°) + isin(300°)) into rectangular form z = a + bi and determines that a = 4 and b = 4 StartRoot 3 E
Anastaziya [24]

Answer:

Option C) The value of a is correct, but the value of b is incorrect.

Step-by-step explanation:

z = 8(cos(300°) + isin(300°))

z = 8cos(300°) + 8isin(300°)

z = 4 + i(-4\sqrt{3})\\z=4-i(4\sqrt{3} )\\

So we can see that a = 4 which is correct but b = -4\sqrt{3} and b in the question says it is b 4\sqrt{3} so its incorrect so Option C is your answer.
