$3-2i/5+i$

$\frac{3*5+(-2)*1)+(-2*5-3*1)i}{5^2+1^2}$

$\frac{13-13i}{26}=\frac{1-i}{2}$

$=\frac{1}{2}-\frac{1}{2}i$

Hope this helps!

Brandon bought a new pair of shorts at the store when they were having a 10% off sale. If the regular price of the pair of short

spayn [35]

You would multiply the orignial price by (10%) converted to decimal to find the discount:
21 * 0.10
=2.10

Then, you subract the discount from the original price to see how much he paid:

21 - 2.10 = $18.90

The Greek mathematician Eratosthenes (ca. 276-195 BC) measured the circumference of the earthfrom the following observations. He

denpristay [2]

Answer:

Radius of the Earth is 3978.8 Miles

Circumference of the Earth is 25000 Miles

Step-by-step explanation:

The angle of the sun shone at an angle of 7.2° to the zenith

This means that the angle of the sector of the circle is 7.2° (θ)

S = Length of the sector of the circle = 500 miles

r = radius of earth

Converting 7.2° to radians

$\theta =7.2\frac{\pi}{180}$

$S=r\theta\\\Rightarrow r=\frac{S}{\theta}\\\Rightarrow r=\frac{500}{7.2\frac{\pi}{180}}\\\Rightarrow r=3978.8\ Miles$

∴ Radius of the Earth is 3978.8 Miles

$C=2\pi r\\\Rightarrow C=2\times \pi \frac{500}{7.2\frac{\pi}{180}}\\\Rightarrow C=25000\ Miles$

∴ Circumference of the Earth is 25000 Miles
