Answer:
8-3i
Step-by-step explanation:
The complex additive inverse is the number we need to add so that we get zero. It is the negative of the number.
a + bi is –(a + bi) = –a – bi.
a+bi + (-a+-bi) = a-a + bi-bi = 0
The complex additive invers of -8+3i is
-(-8+3i)
Distribute the negative
8 -3i
ANSWER
A (-∞,-2)
B (0,4).
EXPLANATION
The portion of the graph that is above the x-axis is considered positive.
From the graph the curve is above the x-axis on the interval
(-∞,-2) and (0,4).
The first and second options are correct.
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ), b = 75
The formula is: y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.
The first thing we must do for this case is to observe the highest relative frequency of the table in the total column.
For the white car we have:
Male = 0.11
Female = 0.20
Total = 0.31
The percentage is given by:
(0.31) * (100) = 31%
Answer:
The percentage that represents the car bought most often is:
31%
Answer:
¹/₂₄
Step-by-step explanation:
Debbie used ⅚ of the cord for necklaces.
That left ⅙ of the cord for four bracelets.
Each bracelet used:
Fraction of cord = ⅙ ×¼ = ¹/₂₄
Debbie used ¹/₂₄ of the cord for each bracelet.
