a bird of species a when diving can travel four times as fast as a bird of species b top speed if the total speeds of these two

weeeeeb [17]

X will be the speed of species b and 4x will be the speed of species a:

x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h

If species b has a speed of 36 m/h, the speed of species a is 4 times that:

4 x 36 = 144 m/h.

Answer:

$\boxed {\bf A~=~36~m/h~and~B~=~144~m/h}$

Hope it helped,

Suppose f and g are continuous functions such that g(6) = 6 and lim x → 6 [3f(x) + f(x)g(x)] = 45. Find f(6).

aleksandr82 [10.1K]

Since g(6)=6, and both functions are continuous, we have:

$\lim_{x \to 6} [3f(x)+f(x)g(x)] = 45\\\\\lim_{x \to 6} [3f(x)+6f(x)] = 45\\\\lim_{x \to 6} [9f(x)] = 45\\\\9\cdot lim_{x \to 6} f(x) = 45\\\\lim_{x \to 6} f(x)=5$

if a function is continuous at a point c, then $lim_{x \to c} f(x)=f(c)$ ,

that is, in a c ∈ a continuous interval, f(c) and the limit of f as x approaches c are the same.

Thus, since $lim_{x \to 6} f(x)=5$ , f(6) = 5
