so both of them ate 7 and means that they both ate 7 ,cause 7+7=14 and since there are 2 of them so divide by 2 ...14÷2=7 so that means they both ate 7 chloride bananas.... not sure
Answer:
See below.
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).. (Answer).

I=PRT/100
I=5000*10*4=200,000/100
I=$2000
Answer:
c = 
- d
Step-by-step explanation:
Multiply both sides by 2 to eliminate the fraction
2A = b(c + d) ← divide both sides by b
= c + d ← subtract d from both sides
- d = c
Answer:
Step-by-step explanation:
It's the <em>magnitude</em> of the average rate of change that's important here.
| -12.5 | is greater than | 10 |. The negative sign tells us that the function is decreasing on the given interval.
