<span>2 x - y - 7 = 0
y =2x - 7 slope = 2
</span><span>perpendicular slope = -1/2
</span><span>line passing through point (4, -1) 
y = mx + b
-1=-1/2(4) + b
-1  = - 2 + b
b = 1

What is the equation of the line that represents the horizontal asymptote of the function f(x)=25,000(1+0.025)^(x)?
posledela

Answer:

The answer is below

Step-by-step explanation:

The horizontal asymptote of a function f(x) is gotten by finding the limit as x ⇒ ∞ or x ⇒ -∞. If the limit gives you a finite value, then your asymptote is at that point.

\lim_{x \to \infty} f(x)=A\\\\or\\\\ \lim_{x \to -\infty} f(x)=A\\\\where\ A\ is\ a\ finite\ value.\\\\Given\ that \ f(x) =25000(1+0.025)^x\\\\ \lim_{x \to \infty} f(x)= \lim_{x \to \infty} [25000(1+0.025)^x]= \lim_{x \to \infty} [25000(1.025)^x]\\=25000 \lim_{x \to \infty} [(1.025)^x]=25000(\infty)=\infty\\\\ \lim_{x \to -\infty} f(x)= \lim_{x \to -\infty} [25000(1+0.025)^x]= \lim_{x \to -\infty} [25000(1.025)^x]\\=25000 \lim_{x \to -\infty} [(1.025)^x]=25000(0)=0\\\\

Since\  \lim_{x \to -\infty} f(x)=0\ is\ a\ finite\ value,hence:\\\\Hence\ the\ horizontal\ asymtotes\ is\ at\ y=0

-5 1/3 converted to an improper fraction
julsineya [31]

Answer:

-16/3

Step-by-step explanation:

as the mixed fraction is -5 1/3

first multiply the denominator with the whole number 3 x -5 = -15

then you add 1 to the whole number without the negative sign = -16

the improper fraction then equal -16/3

A box is 50 cm long. Which of these is closest to the length of this box in feet? (1 inch = 2.54 cm)
goblinko [34]

First, convert cm to inches.

50/2.54 is roughly 19.69

There are 12 inches in a foot, so divide the 19.69 by 12.

19.69/12 is roughly 1.64

So the answer is C
