The value of y is inversely proportional to the value of x. When y=40, x=5. What is the value of y when x=8

1 answer:

5 0

Since x and y are inversely proportional:

xy = c, where c is a constant

when y = 40 and x = 5 -> c = 40*5 = 200

So xy = 200

Then, when x = 8, y = 200/8 = 25

Let the function f be continuous and differentiable for all x. Suppose you are given that f(−1)=−3, and that f'(x) for all value

Monica [59]

Answer:

Step-by-step explanation:

By MVT,

$f'(c) = \frac{f(5)-f(-1)}{5-1}$

$4f'(c)= f(5) + 3\rightarrow f(5) = 4f'(c) - 3$

Moreover, $f'(x)\leq 4~~~~~~ \forall x,$

$f(5) \leq 16 - 3 =13$

Hence the largest possible value of f(5) is 13
