Which complex number's graph is shown?
Answer: Option D.
Step-by-step explanation:
When we want to graph a complex number in a coordinate axis, the real part of the complex number is represented by the x-axis, and the complex part is represented by the y-axis.
in this case, we can see that the coordinates of the point are:
(-2, 2)
Then the complex number is:
Z = -2 + 2*i
Now we need to see which one of the given options is equal to this.
Let's check the real part for every option, so we can discard some of them:
A) real part = -2*cos(135°) = 1.41 (we can discard this option)
B) real part = 2*cos(7*pi/4) = 1.41 (we can discard this option)
C) real part = √2*2*cos(225°) = -2
D) real part = √2*2*cos(3*pi/4) = -2
So options C or D are the correct one, now let's check the complex part for each one
C) complex part = √2*2*sin(225°) = -2 (we can discard this option)
D) complex part = √2*2*sin(3*pi/4) = 2
So the correct one is the D option.

Consider the following system of equations.
a+b-4c=1
a+4b+c=12
a-3b-2c=-5
Show that (3,2,1) is a solution to the system
Answer:
Step-by-step explanation:
a+b-4c-a-4b-c=1-12, -3b-5c=-11
a+4b+c-a+3b+2c=12+5, 7b+3c=17
3(-3b-5c)+5(7b+3c)=3(-11)+5(17)
-9b-15c+35b+15c=-33+85
26b=52
b=2, making 7b+3c=17 become
14+3c=17

Answer:
6/(2+k)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_a(b)=\dfrac{\log(b)}{\log(a)}[/tex]
Using this, we can take the logarithm base 2 in the change of base formula for the given expression.
[tex]\log_{20}(64)=\dfrac{\log_2(64)}{\log_2(20)}=\dfrac{\log_2(2^6)}{\log_2(2^2\cdot5)}\\\\=\dfrac{6}{\log_2(2^2)+\log_2(5)}=\boxed{\dfrac{6}{2+k}}[/tex]
__
In addition to the change of base formula, the usual rules of logarithms apply.
[tex]a^b=m\ \longleftrightarrow \ \log_a(m)=b\\\log(ab)=\log(a)+\log(b)[/tex]

Step-by-step explanation:
Area (A) = πr²
Circumference (C) = 2πr
Blue Circle:
A = (5)²π
A = 25π
C = 2(5)π
C = 10π
Pink Circle:
A = (6)²π
A = 36π
C = 2(6)π
C = 12π
White Circle:
r = 3
A = (3)²π
A = 9π
C = 2(3)π
C = 6π
Red Circle:
A = (7)²π
A = 49π
C = 2(7)π
C = 14π
Find the value of x in (5,x),(x,14) so that the line line containing them is 7/2.
Answer:
7
Step-by-step explanation:
If what you meant by 7/2 was the slope of the line then we can plug in the two points into the slope formula to get our line:
14-x/x-5 = 7/2
This means that 14 - x = 7 and x - 5 = 2. We can see that 14 -7 = 7 and 7 - 5 = 2,
meaning that the value of x should be 7.

Answer:
[tex]\Huge\boxed{x<-\frac{1}{4}}[/tex]
Step-by-step explanation:
Hello there!
The first thing we want to do is find the least common denominator which would be 20
so we multiply the denominator and numerator of the fractions on the left side by 4
3x4=12
5x4=20 -12/20x
1x4=4
5x4=20 so now we would have
[tex]-\frac{12}{20}x+\frac{4}{20} >\frac{7}{20}[/tex]
once again we want to isolate the variable using inverse operations
to get rid of the 4/20 we subtract each side by 4/20
[tex]\frac{7}{20} -\frac{4}{20} =\frac{3}{20}[/tex]
now we have
[tex]-\frac{12}{20} x>\frac{3}{10}[/tex]
now we want to get rid of the -12/20
to do so we divide each side by -12/20 (or -.6 as a decimal to make it easier)
[tex]\frac{3/20}{-.25}=-\frac{1}{4}[/tex]
REMEMBER flip the equality sign
we're left with
[tex]x<-\frac{1}{4}[/tex]

You are dealt one card from a standard 52-card deck. Find the probability of being dealt an ace or a 6.
Answer:
2/13
Step-by-step explanation:
Since there's 4 of each card in the deck this means that there're 4 sixes and 4 aces, so 8 cards in a 52 card deck gives the problem 8/52 which equals 2/13

Option D is the correct answer.
What is triangle congruency?There are ways to prove that two triangles are congruent.
- Side-Side-Side (SSS) Congruence.
The three sides of one triangle are equal to the corresponding three sides of another triangle.
- Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
- Angle-Side-Angle (ASA) Congruence.
The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.
- Angle-Angle-Side (AAS) Congruence.
We have,
Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
So,
The ΔABC, ΔFGE, and ΔPQR are congruent since there is a congruent angle between the corresponding equal sides in all three triangles.
Thus,
The ΔABC, ΔFGE, and ΔPQR are congruent by SAS.

total of 342 tickets were sold for school play. They were either adults tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
Answer:
684 I think ?!
Step-by-step explanation:
Answer: 114 adult tickets were sold.
Step-by-step explanation:
Let student tickets be represented as 2t (since twice the amount of student tickets were sold)
and let t represent the amount of adult tickets.
Solve for t (number of tickets)
342= 2t + t. Combine like terms.
342= 3t. Divide both sides by 3.
114=t
114 adult tickets were sold.
Substitute 114 for t to find student tickets.
2(114)= 228 student tickets were sold.

How can this model be used to determine 2.4−0.15 ? Enter your answers in the boxes. The model shows a total of 2 wholes and 4 tenths. After regrouping 1 tenth into 10 hundredths, there are 2 wholes, tenths, and hundredths. After crossing out 1 tenth and 5 hundredths, there are 2 wholes, tenths, and hundredths remaining. Therefore, the difference of 2.4 and 0.15 is .please help fast
Answer:
2.25
Step-by-step explanation:
2.4 - 0.15
Using place value :
2 = Unit (2 wholes)
4 = tenth place ( 4 tenths)
To subtract 0.15
0 wholes ; 1 tenth ; 5 hundredth
1 tenth can be split into 10 separate hundredths
Hence,
For 2.4
We have ;
2 wholes ; 3 tenths and 10 hundredths
Subtracting 0.15 ;0 wholes ; 1 tenth ; 5 hundredth
(2 - 0) wholes = 2 whole
(3 - 1) tenth = 2 tenth
(10 - 5) hundredth = 5 hundredth
Hence, the difference between (2.4 and 0.15) is :
2 whole ; 2 tenth ; 5 hundredth
Which is equal to : 2.25

Find x in the triangle below. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
Remark
x is opposite the 90 degree angle. It is the hypotenuse. 13 makes up the 57 degree angle. It is the side adjacent.The adjacent side and the hypotenuse define the cos(theta).Formula
cos(theta) = adjacent side / hypotenuse
Givens
Theta = 57 degrees
Hypotenuse = x
Side adjacent = 13
Solution
Cos(57) = 13 / x Multiply both sides by xx*cos(57) = 13 Divide by cos(theta)x = 13/cos(57)x = 13 / cos(57)cos(57) = 0.5446x = 13/ 0.5446x = 23.87
