Use distance formula (Pythagorean theorem) to find the complex number's distance from zero. There is an imaginary axis and a real axis, and these behave very much like the regular x and y axes. √(2² + 4²) = √20
The absolute value of 2 + 4i is √20
The answer is 1954. Letter C is correct
Solution:
If P(x) = <span>165,000
</span>Then
165,000 = 55,000(x - 1945<span>)^(1/2)
x= 1954
to check it, substitute x
</span>165,000 = 55,000(1954 - 1945)^(1/2)
165,000 =165,000
D ( -b, h)
E ( b, h)
F ( b, -h)
G ( -b, -h)
from 0 to E, x=b, from 0 to DG, x= -b
from 0 to DE, y=h, from 0 to GF, y= -h
65 balloons are counted by Chet
<u>Solution:
</u>
Given that
Chet counts balloons for a party
Number of bunches of balloons counted by Chet = 13
Also each bunch has 5 balloons.
Need to calculated how much balloons is counted by Chet
Number of balloons in 1 bunch = 5
Number of balloons in 13 bunches = 13 x Number of balloons in 1 bunch = 13 x 5 = 65
As number of bunches of balloons counted by Chet = 13
So number of bunches of balloons counted by Chet = Number of balloons in 13 bunches = 65
Hence 65 balloons are counted by Chet.
