You purchased a boat for $19,000 and can expect the boat to depreciate at an annual rate of 7.3%. What will the value of your car be 4 years after purchasing it

$14,030.48

Step-by-step explanation:

We can use the following formula to solve:

P = principal value

r = rate (decimal)

t = time (years)

First, lets change 7.3% into a decimal:

7.3% -> -> 0.073

Next, plug in the values:

The value will be $14,030.48

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
