Answer:
y = 5/2x
y = 35/2
Step-by-step explanation:
direct variation
y = kx
Substitute the values for x and y
15 = k(6)
Divide each side by 6 yo find k
15/6 = k
5/2 = k
The equation is y = 5/2 x
Now we know x =7
y = 5/2(7)
y = 35/2
Answer:
No, it can not be applied.
Step-by-step explanation:
f(x) = 1/x²
f(x) is a polynomial that is not continuous
As,
f(x) = 1/0 is undefines
Secondly, it is not differentiable (i.e. the derivative does not exists on the interval given)
Derivative of this function
f'(x) = (1)x^-2
= -2x^(-2-1)
= -2x^(-3)
= -2/x³
= -2/x³
f'(0) = -2/0 is undefined
Thus, mean value theorem can not be applied.
