If we consider the positive value of b, then the value of b is 4.
<h3>What is the coordinate plane of a complex number?</h3>
A complex number in the form z = x + iy takes a coordinate plane in terms of (x,y). From the given information, we are given a distance between two points:
- 25 + bi = (25,b)
- 13-31i = (13, -31)
Now, the distance between two points can be represented by using the relation:
Taking the square of both sides
1369 = 144 + (31 + b)²
1369 - 144 = (31 + b)²
1225 = (31 + b)²
(31 + b)² = (35)²
(31 + b) = ±35
b = 35 - 31 or -35 -31
b = 4 or -66

Answer:
Step-by-step explanation:
The key and the most critical step is to draw the line first. Don't do anything else before that.
(2,-8) (-2,-8)
What you find out is that the y value is always - 8.
So the line has no slope and any x value
y = 0*x + b
y = - 8 is the equation of the line.
Answer:
Veronica ran 3.075 miles.
Step-by-step explanation:
In order to find how far Veronica ran, we'll have to multiply the amount of times she ran around the track by the length of the track.
1.5 * 2.05 = 3.075
You can leave the answer as is or round it to 3.1
Answer:
49,400,000
Step-by-step explanation:
(2.6*10^5)(1.9*10^2)
Apply exponent rule
=2.6*1.9*10^5+2
Add the numbers: 5+2=7
=2.6*1.9*10^7
Multiply the numbers: 2.6*1.9= 4.94
10^7*4.94
10^7=10,000,000
=10,000,000*4.94
Multiply the numbers: 4.94*10000000=49,400,000
=49,400,000
