Answer:
Step-by-step explanation:
in complex number land there are two distict parts real.. the first number and imaginary.. the second number with the i
if your problem really only has a 7 and an i in it.. then it looks like below
7 * i = 7i
but..I suspect you just left out a bit of the problem.. repost .. i'll answer it again if the problem is different that what you posted already :)
The number is 18.
In order to find this, we need to take each side and turn them into mathematics statements.
Five times the sum of a number and 3.
5(x + 3)
3 times the difference of twice the number and 1
3(2x - 1)
Now that we have these, we can set them equal to each other and solve.
5(x + 3) = 3(2x - 1) ----> Distribute
5x + 15 = 6x - 3 -----> Subtract 5x from both sides
15 = x - 3 -----> Add 3 to both sides
18 = x
Answer:
,
Step-by-step explanation:
Note I'm using a, instead of theta to represent angles.
To convert rectangular to polar, apply these formulas
Note : Rectangular coordinates are the coordinates you were learning since elementary school or middle school.
The first number is x, and the second is y.
So
Since our y coordinate is negative and x coordinate is Positve , on the unit circle, the angle must be in the fourth quadrant.
So the angle must be in between
So our answer is
(6, 11pi/6).
5(3x-6/7)
1) 5×3x=15x
ii)5×-6/7=-30/7
2)15x=-30/7 3)15x/15=-30/7/15 (4)x=-2/7or -
0.9
steps
1)multiply 5 with what you have in the bracket.
2)divide both sides by15 to get the value of x
3)and whatever you get is the answer.
Answer:
The blue area is the difference between the area of the 8 ft diameter rug and the area of the 6 ft diameter rug.
Step-by-step explanation:
From each diameter, you can figure out the appropriate radius. Then find the area of the larger circle & subtract from that the area of the smaller circle, using the formula Area = pi•radius2 for each circle.
Please mark me as brainliest, hope this helped.
