What is the domain of the function y = l n (StartFraction negative x 3 Over 2 EndFraction).
Ymorist [56]

The domain of the provide function where the function is defined is x less than the number three.

<h3>What is the domain of the function?</h3>

Domain of a function is the set of all the possible input values which are valid for that function.

The function given in the problem is,

y=\ln\left(\dfrac{-x+3}{1}\right)

The above function is the function of logarithm. For the logarithmic function, it is defined for all the real numbers except 0.

Thus, the function should be greater than zero as,

\left(\dfrac{-x+3}{1}\right) > 0\\(-x+3) > 0\\-x > -3

Change the sign of both side, by changing the inequality,

x < 3

Thus, the domain of the provide function where the function is defined is x less than the number three.

A mountain in boone county is eroding and losing elevation at a rate of 5% every millennium. if the current elevation is 1,710 m
aliina [53]

Answer: 1,393 meters tall

Step-by-step explanation:

Plug in 1710 meters for the initial amount, 0.05 for the rate of decrease, and 4 millennia for the time elapsed.

y

= a(1–r)t

y

= 1,710(1–0.05)4 Plug in values

y

= 1,710(0.95)4 Subtract

y

= 1,710(0.81450…) Simplify

y

= 1,392.80568… Multiply

Round to the nearest whole number.

1,392.80568… → 1,393

To the nearest whole number, the mountain will be 1,393 meters tall.
