Answer:
<h2>3(cos 336 + i sin 336)</h2>
Step-by-step explanation:
Fifth root of 243 = 3,
Suppose r( cos Ф + i sinФ) is the fifth root of 243(cos 240 + i sin 240),
then r^5( cos Ф + i sin Ф )^5 = 243(cos 240 + i sin 240).
Equating equal parts and using de Moivre's theorem:
r^5 =243 and cos 5Ф + i sin 5Ф = cos 240 + i sin 240
r = 3 and 5Ф = 240 +360p so Ф = 48 + 72p
So Ф = 48, 120, 192, 264, 336 for 48 ≤ Ф < 360
So there are 5 distinct solutions given by:
3(cos 48 + i sin 48),
3(cos 120 + i sin 120),
3(cos 192 + i sin 192),
3(cos 264 + i sin 264),
3(cos 336 + i sin 336)
The slope is -3x i think
just a tip there’s this website (i think there’s an app too?). allied khan academy it’s basically for school and there’s lots of videos of what you’re doing
Answer:
Felines: 40%
Reptiles: 25%
Aquatic Animals is 35%
Which means the Answer is 35%
(How you do this)
- First, Divide, the Numerator, by the Denominator and multiply it by 100.
Answer: 1.18 OR 0.18
Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
-4+7x=3 add 4 to both sides
7x=7 divide 7 on both sides
x=1
