What is the average rate of change of y with respect to x over the interval [1, 5] for the function y = 4x + 2?

Reika [66]

y = 4x + 2

y(5) = 4(5) + 2 = 22
y(1) = 4(1) + 2 = 6

average rate of change = (22-6)/(5-1) = 16/4 = 4

What is the following quotient? 5/ sqrt 11 - sqrt 3

nasty-shy [4]

$\displaystyle\\\frac{5}{\sqrt{11}-\sqrt{3}}=?\\\\\\\text{We rationalize the denominator.}\\\\\frac{5}{\sqrt{11}-\sqrt{3}}=\frac{5(\sqrt{11}+\sqrt{3})}{(\sqrt{11}-\sqrt{3})(\sqrt{11}+\sqrt{3})}=\frac{5(\sqrt{11}+\sqrt{3})}{(11-3)}=\boxed{\bf\frac{5\sqrt{11}+5\sqrt{3})}{8}}$

How to do step by step?

We know the opposite side (10) and the adjacent side (7), so we can use tangent to find angle B. Since tan = opposite side/adjacent side, we can set up this equation: tan(B) = 10/7. We can get B on its own by making the equation this: $B = tan^{-1} (10/7)$

Now, we plug this into our calculator to get:

B = 55°, so angle B is 55°.
