If this is referring to a line of best fit, take a ruler and line it up so that there are roughly equal amounts of dots on each side, then trace the ruler.

Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a star

n200080 [17]

Answer:

Step-by-step explanation:

<u>Approximate Roots of Functions:</u>

We are required to find the root of

$\displaystyle 5^{-x}+7=\ 2x+4$

Let's construct a function

$\displaystyle f(x)=\ 5^{-x}+7-2x-4$

Reducing:

$\displaystyle f(x)= 5^{-x}-2x+3$

The equation will have a solution when f(x)=0. We'll start from the approximate crossing point given in the graph (x=1.5)

$\displaystyle f(1.5)=5^{-1.5}-2(1.5)+3\ =0.089$

We'll move up on x=1.52

$\displaystyle f(1.52)=5^{-1.52}-2(1.52)+3=\ 0.046$

We are closer to the solution, let's try some more up

$\displaystyle f(1.54)=5^{-1.54}-2(1.54)+3=\ 0.0038$

This value x=1.54 is close enough to the solution of the original equation

From the options given, $\frac{25}{16}$ is the closest to our solution

$\boxed{Answer:\ x=25/16}$

Find the percent of increase from 33 songs to 63 songs. Round to the nearest tenth of a percent if necessary.

Goshia [24]

Answer:

$90.9$ %

Step-by-step explanation:

First, note that $63/33=21/11= 1~10/11$ .

Recall that $1/11=0.090909090909...$ . This means that $10/11=1-1/11=1-0.0909090909...=0.909090909090...$

This means that the percentage increase was $90.9$ %
