Answer:
x=0,1,±2
Step-by-step explanation:
x^3(x^2-5)=-4x
x^2(x^2-5)=-4
Take x^2=a, we have
a*(a-5)=-4, a^2-5a+4=0, (a-1)(a-4)=0, a=1,4
x^2=0, 1, 4. x=0,1,±2
Answer:
the distance between the two points are 2√10 or 6.32455532
The third choice - 65.3%.
He made 66 successful attempts out of 101 total free throws. To find the experimental probability, it will be 66 divided by 101.
66 successful / 101 total attempts = 0.6534
Rounded off to the nearest tenth of a percent - 65.3%
The experimental probability that you make a free throw is 65.3%.
