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.

= a(1–r)t

= 1,710(1–0.05)4 Plug in values

= 1,710(0.95)4 Subtract

= 1,710(0.81450…) Simplify

= 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.

15% of x is 27, x= what? please helppp meeee

natta225 [31]

Answer:

$\huge \boxed{x=180}$

Step-by-step explanation:

15% of x = 27

$\sf 15\% \cdot x =27 \\\\\\ 0.15x=27 \\\\\\ Divide \ both \ sides \ by \ 0.15. \\\\\\ \frac{0.15x}{0.15} = \frac{27}{0.15} \\\\\\ x = 180$

15% of 180 is 27.

What is the horizontal asymptote of f(x)=-2x/x+1 A.-2 B.-1 C.0 D.1

Mrrafil [7]

A horizontal asymptote of a function f(x) is given by y = lim f(x) as x --> ∞ and x --> –∞. In this case,
$\lim_{x \to \infty} \frac{-2x}{x+1} = \lim_{x \to \infty} \frac{-2x}{x(1+ \frac{1}{x} )}\\
=\lim_{x \to \infty} \frac{-2}{1+ \frac{1}{x} }\\
= -2
$

Thus, the horizontal asymptote of f(x) is y = –2.
