Given z = 1 – i, which letter represents z3?
A
B
C
D
Answer:
A
Step-by-step explanation:
I just took the quiz
Iota is an imaginary unit number that is denoted by i and the value of iota is [tex]i=\sqrt{-1}[/tex]
Letter A represent [tex]z^{3}[/tex]
Given that, z = 1 - i
Now finding [tex]z^{3}[/tex] ,
[tex]z^{3}=(1-i)(1-i)(1-i)\\\\=(1+i^{2-2i} )(1-i)\\\\=1+i^{2}-3i-i^{3}+2i^{2}\\\\=1-1-3i+i-2\\\\=-2-2i[/tex]
In given diagram, it is observed that Point A is [tex]-2-2i[/tex].

y=
Answer:
-4y=40
y=-10
x-3(-10)=17
x-30=17
x=17+30
x=47
Step-by-step explanation:
Answer:
x= 5
y= -4
Step-by-step explanation:
x= 17+3y so you substitute what you got for x in so
17 +3y +7y = -23
10y=-40
y=-4 now you put -4 in for y in the first equation
x = 17 + (3 times -4)
x = 17 - 12

Evaluate acb−(a+d) if a=−2 , b=3 , c=−12 , and d=−4 .
Answer:
78Explanation:
acb − (a + d)
a = -2b = 3c = -12d = -4= (-2) (-12) (3) - (-2 + -4)
Parenthesis: (-2 + -4) = -6
= (-2) (-12) (3) - (-6)
Simplify (-2) (-12) (3): 72
72 - (-6)
78if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is acb−(a+d)
a times c times b minus a plus d
The values of a, b, c and d are given.
In the given expression a,b,c and d are variables and plus and minus are operators
a=−2 , b=3 , c=−12 , and d=−4 .
Substitute these values in expression acb−(a+d)
(-2)(-12)(3)-(-2+(-4))
When minus is multiplied two times we get positive, if three times we get negative
72-(-2-4)
72-(-6)
Seventy two plus six
72+6
Seventy eight
78
Hence if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.

You roll a 6-sided die.
What is P(not odd)?
Write your answer as a percentage.
Answer:
[tex]\boxed{\textsf{ Hence the percentage probability of getting a not odd is \textbf{ 50\% }.}}[/tex]
Step-by-step explanation:
Given that we roll a 6 sided dice . We need to find the probability that the outcome is not a odd number . So , when we roll a dice then the possible outcomes are ,
[tex]\sf\implies Sample\ space = \{ 1,2,3,4,5,6 \}[/tex]
And the total number of possible outcomes is 6 . That is ,
[tex]\sf\implies n(Sample \ space )= 6 [/tex]
Now the total number of non odd numbers that is even numbers is 3 ( 2 , 4 & 6) .
[tex]\sf\implies n(Outcomes_{(even)})= 3 [/tex]
Now , lets use the formula of Probability that is ,
Probability :-
[tex]\qquad\boxed{\boxed{\sf P = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes }}}[/tex]
Now put on the respective values :-
[tex]\sf\implies P( getting\ a \ not \ odd ) = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes } \\\\\sf\implies P( getting\ a \ not \ odd ) =\dfrac{3}{6} \\\\\sf\implies \boxed{\sf P( getting\ a \ not \ odd ) = \dfrac{1}{2} }[/tex]
[tex]\rule{200}2[/tex]
Expressing the probability as percentage :-
[tex]\sf\implies \% \ of \ getting \ non \ odd = Probability \times 100 \\\\\sf\implies \% \ of \ getting \ non \ odd = \dfrac{1}{2}\times 100 \\\\\sf\implies \boxed{\pink{\frak{ \% \ of \ getting \ non \ odd = 50\%}}}[/tex]

Hillside orchard grows Fiji apples and Gala apples. There are 160 Fiji apple trees and 120 Galla apple trees in the orchard. Hillsides Orchers owners decide to plant 30 new gala apple trees. find the number of new Fiji apple trees the owner should plant if they want to maintain the same ratio of Fiji apple trees to gala apple trees
The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.
RatioRatio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
The ratio of Fiji apple to Gala apple = 160 : 120 = 4 : 3
If 30 new gala trees are planted, hence the number of gala trees increases to 150 (120 + 30). To maintain the same ratio:
Number of fiji apple = (4/3) * 150 = 200
New Fiji apple trees = 200 - 160 = 40
The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

Answer:
only Katie is right
Step-by-step explanation:
first, find the nth rule using the equation n = a + (n - 1)d
a = first term (here, it's 22)
n = the position of a term
d = the constant difference between each term (here, it's -5 since each term reduces by 5)
put these in and then simplify:
n = a + (n - 1)d
n = 22 + (n - 1)(-5)
n = 22 - 5n + 5
n = -5n + 27
this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!

What is the equation of the line that passes through point (-1,4) and is perpendicular to the following equation? y= -1/2x - 4
Answer:
y=2x-4
Step-by-step explanation:
To find an equation perpendicular to another one, you must find the negative inverse of the slope.
In this case, -1/2 has an inverse of -2, but because we're finding the negative inverse, the two negatives cancel out and we get 2, the slope of our perpendicular equation, which crosses the initial equation, making a right angle.

What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The equation which represents the line of best fit for the distance in feet) that Marcella traveled over time (in seconds) based on several races she ran is,
⇒ y = 9.50x + 0.4
Hence, Marcella's average speed in feet per seconds is,
y = 9.50x + 0.4
Put x = 1;
y = 9.50 × 1 + 0.4
y = 9.50 + 0.4
y = 9.54 feet
Thus, Marcella's average speed in feet per seconds is,
