A = P (1 + r)^n where P = initial amount, r = interest rate , n = number of years and A = amount after n years.

So here we have A = 1393(1 + 0.09) ^ 2 ( 0.09 = 9%)

= $1655.02 (answer)

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.

ollegr [7]

Answer:

k=5

Step-by-step explanation:

step 1

Find the equation of the line f(x)

we have the points

(-4,0) and (-2,2)

<em>Find the slope m</em>

$m=(2-0)/(-2+4)\\m=1$

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(-4,0)$

substitute

$y-0=(1)(x+4)$

$y=x+4)$

Remember that

f(x)=y

$f(x)=x+4$

step 2

Find the equation of the line g(x)

we have the points

(-4,0) and (-2,-10)

<em>Find the slope m</em>

$m=(10-0)/(-2+4)\\m=5$

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=5\\(-4,0)$

substitute

$y-0=(5)(x+4)$

$y=5(x+4)$

Remember that

g(x)=y

$g(x)=5(x+4)$

Remember that

$g(x)=kf(x)$ ------> $g(x)=5(x+4)$

therefore

k=5

20 POINTS!!! What is the equation of a function that goes through (0,1) and (1,0)?

Dennis_Churaev [7]

It's a curved line that goes through those points. It's straight, and curves right when it goes through the first point.
