dybincka [34]

Let's take two points so that we can get the equation of the line which goes through those points. P1 (-9, -2), P2 (3, -17):

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-17-(-2)}{3-(-9)}=\frac{-17+2}{3+9}=-\frac{15}{12}=-\frac{5}{4}$ $\begin{gathered} y-y_1=m(x-x_1) \\ y-(-2)=-\frac{5}{4}\cdot(x-(-9)) \\ y+2=-\frac{5}{4}\cdot(x+9)_{} \\ y=-\frac{5}{4}x-\frac{45}{9}-2 \\ y=-\frac{5}{4}x-7 \\ f(x)=-\frac{5}{4}x-7 \end{gathered}$

So, y is the line which goes through the first and last points of the chart.

To proof that the rest of points go through the line as well, we will evalute each point

$\begin{gathered} f(-5)=-\frac{5}{4}\cdot(-5)-7=\frac{25}{4}-7=-\frac{3}{4}\ne-7 \\ f(-1)=-\frac{5}{4}(-1)-7=\frac{5}{4}-7=-\frac{23}{4}\ne-12 \end{gathered}$

Since the evaluation of these points don't correspond to the values of the chart we can assure that the relationship is not linear

The interest rate r required to increase investment p to amount a in t years is found using the formula r=(a/p)^1-t - 1. Find th

valkas [14]

The interest rate would be 20%.

The formula is derived from the compound interest formula

$A=p(1+r)^t$ .

We want to isolate r in this equation to rewrite the formula. The first thing we would cancel, outside parentheses, would be p; divide both sides by p and we have

$\frac{A}{p}=(1+r)^t$

We want to cancel the exponent, t, next. We can raise a power to its reciprocal to undo it; for example, raising a squared amount to the 1/2 power will undo the exponent. We will raise both sides of this to the 1/t power:

$(\frac{A}{p})^{\frac{1}{t}}=1+r$

Now we cancel the 1 by subtracting, giving us

$(\frac{A}{p})^{\frac{1}{t}}-1=r$

Using this formula, we plug in 3600 for A, 2500 for p and 2 for t:
