Answer:
z1 = -17 + 0i
Step-by-step explanation:
Given the complex number z1 =17[cos(π)+isin(π)], we are to express it in rectangular form as shown;
Since cos(π) = -1 and sin(π) = 0, the equation becomes;
z1 =17[cos(π)+isin(π)]
z1 =17[(-1)+i(0)]
z1 = 17(-1 + 0i)
z1 = -17 + 0i
Hence the complex number in rectangular form is expressed as z1 = -17 + 0i

9 1
18 2
27 3
36
45 5
Answer:
9:1, 18:2, 27:3, 36:4, 45:5 or 1,2,3,4,5
Step-by-step explanation:
This is the answer because:
1) We can see that eah ratio is being multiplied with the next number. We can say this because 9 x 2 = 18 and 1 x 2 = 2 which is 18:2 just like that 9 x 3 = 27 and 1 x 3 = 3 which makes the ratio 27:3.
2) If we keep on doing this, 9 x 4 = 36 and 1 x 4 = 4 which makes the ratio 36:4.
Therefore, the answer is 4.
Hope this helps! :D

Identify the number of zeros for each function
P(x) = 8x^2+5-1
Answer:
2 zeros
Step-by-step explanation:
Here, we want to identify the number of zeros for the function
The number of zeros a particular function has is dependent on the degree of the function
This particular function is quadratic and has a degree of two
So what this means is that it is expected that the function has two zeros

write the slope intercept form of an equation for the line passing through the following two points: (-2,8) and (-4,-4)
Answer:
y=6x+20
Step-by-step explanation:
m= y2-y1/x2-x1
m= -4-8/-4-(-2)= 12/-2= 6/1

In Louisville, 40% of the population is female and 60% are males. 36% of Louisville's population is under 18. The ratio of males to females who are under 18 is 2:1. If there are 1,176 males who are under 18, what is the population of females who are over 18.
Answer:
1411 females
Step-by-step explanation:
Given that:
Male population = 60%
Female population = 40%
36% of total population are under 18
Ratio of male to female under 18 = 2 : 1
Males under 18 = 1176
Females over 18 =?
The population of females under 18:
If males under 18 = 1176
Then female under 18 = 1176 / 2 = 588
Hence number of population under 18 = (1176 + 588) = 1764
1764 = 36% of the entire population
Hence, (100 - 36)% = 64% of the entire population are over 18
1764 = 0.36
x = 0.72
x = (0.72 * 1764) / 0.36
x = 3528
Hence, 40% of the population above 18 are female
0.4 * 3528 = 1411.2
= 1411 females are over 18
evaluate the expression when x = 3/4. 1 /5 x answer in simplest form

Which number sentence is true?
A. -1/12 times 6/7 = -1/14
b. -1/12 times (-6/7)= -1/14
c. 1/12 times 6/7 = -1/14
d.1/12 times (-6/7) = 1/14
Answer:
We conclude that:
[tex]-\frac{1}{12}\cdot \frac{6}{7}=-\frac{1}{14}[/tex]
Hence, option (A) is true.
Step-by-step explanation:
Let us solve the expression
-1/12 times 6/7 = -1/14Let us solve the L.H.S to check whether it becomes equal to R.H.S
[tex]-\frac{1}{12}\:\times \frac{6}{7}[/tex]
Factor the number: 12=6×2
[tex]-\frac{1}{6\cdot \:2}\cdot \frac{6}{7}[/tex]
Cross - cancel the common factor
[tex]-\frac{1}{2}\cdot \frac{1}{7}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]-\frac{1\cdot \:1}{2\cdot \:7}[/tex]
Multiply the number: 7×2 = 14
[tex]-\frac{1}{14}[/tex]
Therefore, we conclude that:
[tex]-\frac{1}{12}\cdot \frac{6}{7}=-\frac{1}{14}[/tex]
Hence, option (A) is true.

the rectangular post shown at the right measures 2w-30 by w. the poster has an area of 5400 cm^2. what is The value of w ?
Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60
Jerry is a judge. he hears 5 cases every 2 3/8 hours how many cases does he haer per hour
Answer:
2 2/19
Step-by-step explanation:
5 cases in 2 3/8 hours
The unit rate of cases per hour is calculated by dividing the number of cases by the number of hours.
5/(2 3/8) = 5/(19/8) = 5 * 8/19 = 40/19 = 2 2/19
Answer:
2 2/19 cases per hour
Step-by-step explanation:
5 ÷ 2 3/8
~Turn the fraction on the left into an improper one
5 ÷ 19/8
~Copy Dot Flip
5/1 * 8/19
~Multiply
40/19 or 2 2/19

Write 206 in base 7
Answer:
104
Step-by-step explanation:
if A # B means the same thing as 2 A- B, then 1 # ( (2 # 3 ) # 4) equals:
By definition of #,
2 # 3 = 2•2 - 3 = 4 - 3 = 1
(2 # 3) # 4 = 1 # 4 = 2•1 - 4 = 2 - 4 = -2
1 # ((2 # 3) # 4) = 1 # (-2) = 2•1 - (-2) = 2 + 2 = 4
The 1 # ( (2 # 3 ) # 4) equals to 4.
Given that,
if A # B means the same thing as 2 A- B.Based on the above information, the calculation is as follows:
By definition of #,
= 2 # 3
= 2(2) - 3
= 4 - 3
= 1
Now
=(2 # 3) # 4
= 1 # 4
= 2(1) - 4
= 2 - 4
= -2
Now
=1 # ((2 # 3) # 4)
= 1 # (-2)
= 2(1) - (-2)
= 2 + 2
= 4
