5. CD has an endpoint at (2, -1) and a midpoint at (8,3). Which measure is closest to the length of CD?
Alexus [3.1K]

Answer: C

Step-by-step explanation:

the equation for X is

\frac{2+x}{2} =\frac{8}{1}  use proportion to solve

2 + x = 16

x = 14

(14,y)

The equation for Y is

\frac{-1+y}{2} =\frac{3}{1} use proportion to solve

-1 + y = 6

y = 7

(14,7)

now use the distance formula

(14,7) (2,-1)

which gets you 14.4 or C

Complex numbers zj and zz are given by zj = 3- j2, zz = - 4 + j3. (a) express zj and zz in polar form. (b) find lz1l by first ap
inna [77]

Solution:

Given: zj = 3- j2, zz = - 4 + j3

Part a:

zj = 3- j2 = 3.6e^{-j33.7^{\circ}}

zz = - 4 + j3 = 5e^{j143.1^{\circ}}

Part b:

|zj| = |3− j2| =  √3² +(−2)² = √13 = 3.60

|z1| =  √(3− j2)(3+ j2) = √ 13 = 3.60.

Part c:

With the help of part a:

z1z2 = 3.6e^{-j33.7^{\circ}}.5e^{j143.1^{\circ}}

Max said that 36,594 is less than 5,980 because 3 is less than 5 describe Max's error and give the correct answer
DerKrebs [107]
Max is simply incorrect because he's stated his inequality in the opposite fashion that he should have:

36,594 is greater than 5,980

because the 3 in 36,594 represents the ten thousands place and the 5 in 5,980 represents the thousands place (which is a power of 10 less than the ten thousands place)
