Please help!! I included a pic of the problem to make it easier.
Find the quotient (z/w)
z = 6(cos(pi/3) + isin(pi/3), w = 3(cos(pi/6) + isin(pi/6)
[A]2(cos(pi/6)+isin(pi/6)
[B]2(cos(pi/90)+isin(pi/90)
[C]18(cos(pi/2)+isin(pi/2)
[D] None of these
Answer: i think it is D
we have:
[tex]\frac{z}{w}= \frac{6(cos\frac{\pi }{3}+i.sin\frac{\pi }{3} ) }{3(cos\frac{\pi }{6}+i.sin\frac{\pi }{6}) }\\\\\\<=>\frac{z}{w}=\frac{2(\frac{1}{2}+i.\frac{\sqrt{3} }{2}) }{\frac{\sqrt{3} }{2}+i.\frac{1}{2} }\\\\<=>\frac{z}{w}= \frac{2+2\sqrt{3}.i }{\sqrt{3}+i }[/tex]

A group of four friends goes to the movies. Each friend pays for a ticket, a snack, ana
drink. The ticket costs d dollars. The snack costs 1.5 times the price of a ticket
The drink costs $1.25 less than the ticket.
The expression 4d + 4(1.5d) + 4(d - 1.25) represents the amount the
riends pay altogether in dollars.
Which part of the expression represents the total amount the friends
pay for snacks?
d - 1.25
1.5d
4(1.50)
4d - 1.25)
Answer:
the answer is
4(1.5d)
Step-by-step explanation:
hope it help
The expression of the total amount paid on snacks is 4(1.5d).
What is the expression?The expression is a sentence with multiple variables and constants connected via mathematical operator. An expression cannot have an equal to “=” sign.
It is known that the cost of a snack for 1 friend is 1.5 times the price of the ticket, d. So, the cost of a snack for 1 friend will be 1.5d
Multiply the cost of snacks for 1 friend by 4, to determine the total cost spent by 4 friends on snacks.
4(1.5d)
Thus, the expression for the total amount spent on snacks will be 4(1.5d).

The cookies in a jar contain a total of 1000 chocolate chips. All but one of these cookies contains the same number of chips; it contains one more chip than the others. The number of cookies in the jar is between one dozen and three dozen. What is the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip? (Hint: using factorization) (A) 65 (B) 64 (C) 63 (D) 66 (E) 67
Answer:
65
Step-by-step explanation:
From the given information:
Let consider p to be the total numbers of the cookies
If there are 1000 chocolate chips in the jar;
The number of chocolate chips if we remove one chocolate chips = 1000 -1
= 999
The number of available choco chips on each cookie except for the one having an extra chocolate chip = 999/p
Thus, to achieve a whole number, p is required to be a factor of 999
By factorization of 999, we get:
36 > p > 12; Thus, the value for "p" lies between 36 and 12, and which must be by 999 is 27
Thus, the number of cookies in the jar "p"= 27
However, the number of chocolate chips on with the extra chocolate chip
= 999/p + 1
= 999/27 + 1
= 37 + 1
= 38
Thus, the sum of the number of cookies in the jar + the number of chocolate chips on with the extra chocolate chip
= 27 + 38
= 65

O 2 inches equal 5 feet
o 1 inch equals 5 feet
o inch equals 1 foot
O 1 inch equals foot
The scale that Darnell used is required.
The scale that Darnell used is 1 inch equals 5 feet.

9th grade math help pretty please
Answer:
C.) This system has infinitely many solutions.
Step-by-step explanation:
y = 2x - 4
2x - y - 4 = 0
2x - y - 4 = 0 can be rewritten as y = 2x - 4 as shown below
2x - y - 4 = 0
-y = -2x + 4
-y/-1 = -2x/-1 + 4/-1
y = 2x - 4
y = 2x - 4 is equal to 2x - y - 4 = 0 because the slope is both 2 and both its y-intercept is -4, these two are coincidence, as they call it, meaning these two lines are the same, so its solutions are anywhere on its line. Shown below in a graph.

Write 5/3 as a mixed number.
Answer:
1 [tex]\frac{2}{3}[/tex]
One and two thirds
Step-by-step explanation:
Divide the numerator by 3
Write down the whole number answer
Use the remainder as the new numerator over the denominator, which is the fraction part of the mixed number.
I hope this helps!!
The fraction 5/3 as a mixed number is [tex]1\frac{2}{3}[/tex].
To write the fraction 5/3 as a mixed number, we need to find the whole number and the proper fraction parts.
A mixed number is a combination of a whole number and a proper fraction (where the numerator is smaller than the denominator).
Divide the numerator (5) by the denominator (3).
5 ÷ 3 = 1 with a remainder of 2
The quotient (1) represents the whole number part, and the remainder (2) becomes the numerator of the proper fraction.
The denominator remains the same, which is 3.
Hence, the mixed number representation of 5/3 is [tex]1\frac{2}{3}[/tex].

Randy wants to attach a 23 foot string of lights to the top of the 13 foot mast of his sail boat. How far from the base of the mast should he attach the end of the light string?
Answer:
distance from the base where string is attached = 18.97 feet
Step-by-step explanation:
The diagram attached to this solution gives a right-angled triangle formed by attaching the string to the top of the mast. the distance from the base is calculated as follows:
(hypotenuse)² = (opposite)² + (adjacent)²
23² = 13² + d²
529 = 169 + d²
d² = 529 - 169
d² = 360
d = √(360)
d = 18.97 feet
