Find the equation for the line that passes through the point (3,-2), and that is perpendicular to the line with the equation x =

kompoz [17]

Step-by-step explanation:

x = 2 is, as you can see, parallel to the y-axis.

perpendicular to this (= crosses the original line in an angle of 90 degrees) is then a line parallel to the x-axis.

that means y is constant. all points on that line will have the same y value.

and we know one point already : (3, -2)

so all points of the perpendicular line will have y = -2

and that is the equation of the perpendicular line :

y = -2

34. The amount of money in an account with continuously compounded interest is given by the formula 1

kirill115 [55]

Answer:

Step-by-step explanation:

I have no idea what formula that is you're using but the one I teach in both algebra 2 and in precalculus for continuous compounding is

$A(t)=Pe^{rt}$

where A(t) is the amount after the compounding, P is the initial investment, ee is Euler's number, r is the interest rate in decimal form, and t is the time in years. If our money doubles, we just have to come up with a number which will be P and then double it to get A(t). It doesn't matter what number we pick to double, the answer will come out the same regardless. I started with 2 and then doubled it to 4 and filled in the rest of the info given with time as my unknown:

$4=2e^{(.062)(t)}$

Begin by dividing both sides by 2 to get

$2=e^{.062t}$

The only way we can get that t out of its current position is to take the natural log of both sides. Natural logs have a base of e, so

$ln_e(e)=1$ This is because they are inverses of one another. Taking the natural log of both sides:

$ln2=.062t$ Now divide by .062 to get

t = 11.2 years
