22) The base of a lampshade is circular. The circumference of the base is 3 times the radius increased by 4.25 inches.

BARSIC [14]

Answer:

~1.29 inches

Step-by-step explanation:

C = 2πr

C = 3r + 4.25

2πr = 3r + 4.25

2πr - 3r = 4.25

r(2π-3) = 4.25

r = 4.25/(2π-3) ≈ 1.29

Answer:

Step-by-step explanation:

Begin with Euler's formula. I am assuming youre aware of this if youre taking complex algebra? You can prove Euler's formula by doing a Maclaurin expansion of cosine, sine, and e^x. Euler's formula states that:

$e^{ix}=cos(x)+isin(x)$

We can put the first complex number in exponetial form by noticing the input is 2pi/3. The second complex number has an input of pi/3. Therefore:

$z_1=8e^{i(2\pi /3)}$

$z_2=0.5e^{i(\pi /3)}$

Then:

$\frac{z_1}{z_2} =\frac{8e^{i(2\pi /3)}}{0.5e^{i(\pi /3)}}$

Simplify the coefficients to get:

$\frac{z_1}{z_2} =\frac{16e^{i(2\pi /3)}}{e^{i(\pi /3)}}$

When you divide exponentials, you subtract the exponents. Therefore:

$\frac{z_1}{z_2} =16e^{i(2\pi /3)-i(\pi /3)}=16e^{i(\pi /3)$

Put it back into trigonemtric form using Euler's formula:

$16e^{i(\pi /3)}=16cos(\pi /3)+i16sin(\pi /3)$

Cosine of pi/3 is 0.5, and sine of pi/3 is square root of 3 over 2. We have:

$16e^{i(\pi /3)}=16cos(\pi /3)+i16sin(\pi /3)=16*0.5+16*\frac{\sqrt{3} }{2} *i=8+8\sqrt{3} i$

2. Every December, Tagaytay City Science National High School is sponsoring a

kirza4 [7]

Answer:

a: 162

b: 142

Step-by-step explanation:

a: december 1=2

a: december 2=6

a: december 3 = 6 x 3 = 18

a: december 4 = 18 x 3 =54

a: december 5 = 54 x 3 =162

~ triples the number of newspapers means "x3" ~

so on the last day, 162 newspapers

B: sum up all the newspapers:

2 + 6 + 18 + 54 + 162

= 8 + 18 + 54 + 162

= 26 + 54 + 162

= 80 + 162

= 242 all in total newspapers
