Answer:3
Step-by-step explanation: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).
Yes, it is a rational number.
56.25% as a decimal is 0.5625
0.5626 is equal to 5625/10000, which can be simplified to 9/16
This is because the common factor of 5625 and 10000 is 625. We divide the numerator and denominator by 625 to achieve 9/16.
it should be 14 becuse 7 times 2 is 14 so x=14 i took the test
