Certain pieces of antique furniture increased very rapidly in price in the 1970s and 1980s. for example, the value of a particular rocking chair is well approximated by v=150(1.65)^t where v is in dollars and t is the number of years since 1975. find the rate, in dollars per year, at which the price is increasing.

The price is increasing by 65% per year.

Step-by-step explanation:

Since, the exponential growth function,

Where,

a = initial value,

r = rate of increasing per period,

x = number of periods,

Here, the given function,

Where,

t = number of years,

By comparing,

r = 0.65,

i.e. the rate of increasing per year = 0.65 = 65%

here is a big fat

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
