Answer:

a = 20; b = 2√101

Step-by-step explanation:

The triangle at upper left and the one at lower right are similar. Ratios of corresponding sides are equal, so ...

200/a = a/2

400 = a^2

√400 = 20 = a

Then, by the Pythagorean theorem, the value of b can be found:

b = √(a^2 + 2^2) = √(400 +4) = √4·√101

b = 2√101

Which is the function of x?

mash [69]

Answer:

Step-by-step explanation:A function defines one variable in terms of another. The statement "y is a function of x" (denoted y = y(x)) means that y varies according to whatever value x takes on. A causal relationship is often implied (i.e. "x causes y"), but does not *necessarily* exist.
