To find the rate of change of the function y = x^2 at the point (3,10)
Would it be y = 2x,
y = 2(3)
y = 6
is this correct?
The probability that Ari eats ice cream is 0.6
The probability that Barry eats ice cream is 0.8
The probability that Chris eats ice cream is 0.7
What is the probability that Chris Sticks to the diet?
Does this question imply that only chris to the diet and ari and barry don't stick to the diet
or does it imply that chris sticks to the diet regardless of whether Barry and Ari stick to the diet?

How are you meant to know whether a question asking you to find a sin value, for example, sin 225, is asking for the value in degrees or radians?
Would the same apply for cos and tan?

The area of a bushfire, A hectares, t hours after the fire has started is modeled by the rule A = 90t^2 - 3t^3, t > 0
After how many hours does the fire go out
A = 0
90t^2 - 3t^3 = 0
t = 0 and 30
Which answer do i choose? 0 hours or 30 hours?

The probability that a goldfish survives 1 month in a home where there is no cat is 0.9, whereas the probability that a goldfish surviving one month in a home where there is a cat present is 0.3
There is a 40% chance of selecting a home in which a cat is present
What is the probability of a goldfish surviving 2 months in a home where there is a cat present?
Already tried this question, checked the answer but got it wrong
