To divide complex numbers in polar form, divide the r parts and subtract the angle parts. Or

r2(cosθ2 + i sinθ2) / r1(cosθ1 + i sinθ1) = r2/r1(cos(θ2−θ1) + i sin(θ2−θ1))

z1/z2

= 3/7 (cos(π/8-π/9) + i sin(π/8 - π/9))

= 3/7 (cos(π/72) + i sin(π/72))

r1(cosθ1 + i sinθ1) / r2(cosθ2 + i sinθ2) = r1/r2(cos(θ1−θ2) + i sin(θ1−θ2))

z1/z2

=3(cos(pi/8)+isin(pi/8)/7(cos(pi/9)+isin(pi/9)

=3/7(cos(pi/8-pi/9)+isin(pi/8-pi/9)

=3/7(cos(pi/72)+isin(pi/72)

The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate precription. how much total drug did the pharmacist use

FromTheMoon [43]

Answer: 700.067 g

Step-by-step explanation:

Given : The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate prescription.

We know that 1 gram= 1000 milligram

and 1 kilogram = 1000 grams

Then, By UNITARY METHOD, $\text{1 mg}=\dfrac{1}{1000}\text{ gram}$

Now, We convert each amount of drug into grams as ,

$67\ mg=67\times\dfrac{1}{1000}\ g\\\\=0.067\text{ g}$

AND

$0.6\ kg=0.6\times100=60\text{ g}$

Now, the total drug used by Pharmacist (in grams) = $0.067+100+600=700.067\ g$

Hence, Pharmacist used 700.067 g of total drug.

Can someone help me with these functions

ryzh [129]

Answer:

Function 1:

The starting point is (0,0.5)

As x increases, y increases

Function 2:

The starting point is (0,3)

As x increases, y decreases

Step-by-step explanation:

In order to find the starting point, we need to plug in x=0.

$y=0.5+3(0)\\\\y=0.5$

$y=3(0.5)^0\\\\y=3(1)\\\\y=3$

As we plug in increasing numbers into function#1, the y-value increases

As we plug in increasing numbers into function #2, the y-value is decreasing

Which pyramids with base area B and height h have equal volumes?

Pachacha [2.7K]

Option A:

V = 1/3 * b^2 * h

V = 1/3 * 10.5^2 * 6

V = 1/3 * 110.25 * 6

V = 220.5

Option B:

V = 1/3 * b^2 * h

V = 1/3 * 3.6^2 * 8

V = 1/3 * 12.96 * 8

V = 34.56

Option C:

V = 1/3 * b^2 * h

V = 1/3 * 4.2^2 * 12

V = 1/3 * 17.64 * 12

V = 70.56

Option D:

V = 1/3 * b^2 * h

V = 1/3 * 6^2 * 8.4

V = 1/3 * 36 * 8.4

V = 100.8

I guess it's 'None of the Above'

You missed an A in your art course by only 7 points. Your point total for the course was 371. How many points were possible in t

Nikitich [7]

The number of points that were possible in the course is 420

What is the required number of points for grade A?

The number of points the student needs to have to make grade A is the student's current points of 371 plus the 7 points remaining to make grade A

Total points for A=371+7

total points for grade A=378

90% of the course total=378

divide both sides 90

90% /90 =378/90

1%=378/90

100%=378/90*100

100%=420
