Compare the domains of the logarithmic function f(x) and the square root function g(x).

1 answer:

7 0

We have that the logarithmic function has a domain from 0 (without including 0) to plus infinity. That is because of the property that e=2.71 raised to any power is positive. We also have that the square root function is defined only from 0 to plus infinity, since every square of a number is positve or 0. The answer is that the domains differ; they are almost equal, except for the fact that the domain of the square root function additionally contains 0.

A, B & C form a triangle where

slavikrds [6]

Answer:

10.9

Step-by-step explanation:

Pythagoras theorem- a² + b² = c²

Since this is a right angle with each side on the right angle's length given you can use pythagoras theorem.

7² + 8.44² = c²

= 49 + 70.56 = c²

= 119.56 = c²

∴ c = √119.56

= 10.9

350+x=90 * 5

350+x=450

x=450-350

x=100
