Answer:
1150 km/hr
Step-by-step explanation:
Formula for Average Speed is given as = Distance in Kilometers/ Time in Hours
In the question we are given the following parameters.
The length of a planet's orbit around a star = Distance = 17,650,000 km.
Time taken to complete a full orbit = 640 Earth days
Step 1
We need to convert the time in days to hours
1 Earth day = 24 hours
640 Earth days =
We cross multiply
640 Earth days × 24 hours
= 15360 hours.
Step 2
Average Speed = Distance in Kilometers/ Time in Hours
Average Speed = 17,650,000 km. /15360 hours
Average Speed = 1149.0885417 km/hr
Approximately to 3 significant figures=
1150 km/hr
Therefore, the planets average speed in kmh-1 to 3sf is 1150 km/hr
23/8 = 46/16 = 92/32
Answer: 46/16, 92/32

Answer:
Step-by-step explanation:
Nope, x-√6 is a factor of x^4-36. Let solve the question by factorization method.
x^4 - (√6)^4
x^4 - (√6)^4
(x²)² - (√6²)^²
(x²)² - (√6²)^²
(x² - 6)(x² + 6)
Hence, the required factor forms of equation is (x² - 6)(x² + 6)
Therefore, x-√6 is not a factor of x^4-36.
<u>Formula used while solving the problem :</u>
1. a² - b² = (a + b) (a - b)
2. a^4 - b^4 = ( a² + b²)(a² - b²)
