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

alekssr [168]

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.

Step-by-step explanation:

L : length

w : width

p : perimeter

38=2L+2w

38 =2(w+6)+2w

38 = 4w+12

38-12=4w

26=4w

26/4=w

w=6.5 in.

olga2289 [7]

Answer:

A = 3, B = 10

Step-by-step explanation:

$\sqrt{-90}$

= $\sqrt{9(-1)(10)}$

= $\sqrt{9}$ × $\sqrt{-1}$ × $\sqrt{10}$

= 3i $\sqrt{10}$

in the form Ai $\sqrt{B}$

with A = 3 and B = 10

"Find A and B so that the system below has the solution (1, -1)."

Mnenie [13.5K]

To do this you must plug in 1 and negative one for each x variable and each y. that solution is a point so the 1 must be tested for x and the -1 for y. do this and solve to find a and b so that it works in both equations!
