1) Solve the following equations.

a) \[\sqrt{x}-1=3\]

b) \[\sqrt{{{x}^{3}}}=8\] .

c) \[\sqrt[3]{{{x}^{2}}}=4\] .

2) Is \[\sqrt{{{x}^{2}}}=x\] an identity (true for all values of x)?

3) For the equation \[x-\sqrt{x}=0\] , perform the following:

a) Solve for all values of x that satisfies the equation.

b) Graph the functions \[y=x\] and \[y=\sqrt{x}\] on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs.

c) How does the graph relate to part a?

.

4) A right triangle is a triangle with one angle measuring 90°. In a right triangle, the sides are related by Pythagorean Theorem, \[{{c}^{2}}={{a}^{2}}+{{b}^{2}}\] where c is the hypotenuse (the side opposite the 90° angle). Find the hypotenuse when the other 2 sides’ measurements are 3 feet and 4 feet.

5) Suppose you travel north for 35 kilometers then travel east 65 kilometers. How far are you from your starting point?
