Start by pulling out a three
y = 3(x^2 - x - 2) Now it is much easier.
y = 3(x - 2)(x + 1)
Answer:
224.7 days
Step-by-step explanation:
Venus is the second planet out of the nine planets and it precedes the planet earth. Venus has an orbital distance of 0.72 AU from the sun while Earth has an orbital distance of 149.60 million km from the sun. Due to these distances, the Venus completes one orbit around the sun in 224.7 days while the Earth complete one orbit around the sun in 365.256 days but in a leap year, it completes one orbit around the sun in 366 days.
Answer:
37
Step-by-step explanation:
I plugged in the numbers between 35 and 40 and got this. No problem. :)
Even function is symmetrical about the y axis
not sure what it means if the polynomial is positive
the zeroes are how many times it hits the x axis
it hits 4 times so 4 zeros
so, is a semi-circle, half a circle, recall a circle has a total of 360°, so half of that will be 180°.
the diameter of that circle is 10, so its radius is half that, or 5.
