Answer:
first option
Step-by-step explanation:
the area of a rectangle is
base*height

so the sum is

which is the first option
The correct answer among all the other choices is "Statement 1 is a theorem because it can be proved and Statement 2 is a postulate because it is a true fact." Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
D(1/x)/dx= d(x^-1)/dx
= -x^-2
the derivatives of the two cases you mentioned is as follows:
(I) f(x)=k/x
d{f(x)}/dx= k×(-x^-2)
= -kx^-2
(ll) f(x)=x/k
d{f(x)}= d(x/k)/dx
= 1/k
you can just simply take out the constant from the derivative and multiply it to the final answer of the derivative of the given function.
The probability is 4/12 or 1/3
because the total of fish is 12 and the platy fish is 4 or 4 parts of the total 12.<span />
