The purchasing power P (in dollars) of an annual amount of A dollars after t years of 5% inflation decays according to the following formula.† P = Ae−0.05t (a) How long will it be before a pension of $60,000 per year has a purchasing power of $20,000? (Round your answer to two decimal places.)

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

translate k to n and reflect across the line containing jk.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

the answer is b
