C. $66.14 

I'm only saying C without showing work because it's kinda obvious.

If the meal costs $56.36 without including the tip that's akready way more than A, B, or D. So the answer is C.

Which description compares the vertical asymptotes of function A and function B correctly?
neonofarm [45]

Answer:

Option B:

Function A has a vertical asymptote at x = 1

Function B has a vertical asymptote at x = -3

Step-by-step explanation:

A function f(x) has a vertical asymptote if:

\lim_{x \to\\k^+}f(x) = \±\infty\\\\ \lim_{x \to\\k^-}f(x) = \±\infty

This means that if there is a value k for which f(x) has infinity or a -infinity then x = k is a vertical asymptote of f(x). Therefore, the closer x to k approaches, the closer the function becomes to infinity.

We can calculate the asymptote for function A.

\lim_{x \to \\1^+}(\frac{1}{x-1})\\\\ \lim_{x \to \\1^+}(\frac{1}{1^-1})\\\\ \lim_{x \to \\1^+}(\frac{1}{0}) = \infty\\\\and\\ \lim_{x \to \\1^-}(\frac{1}{x-1})\\\\\lim_{x \to \\1^-}(\frac{1}{0}) = -\infty

Then, function A has a vertical asymptote at x = 1.

The asymptote of function B can be easily observed in the graph. Note that the function b is not defined for x = -3 and when x is closest to -3, f(x) approaches infinity.

Therefore x = -3 is asintota of function B.

Therefore the correct answer is option B.

Simplify: -0.8b+4.1c-(-3.2b)-0.1c
BigorU [14]

[ Answer ]

\boxed{2.4b \ + \ 4c}

[ Explanation ]

  • Simplify: -0.8b + 4.1c - (-3.2b) - 0.1c

-----------------------------------

  • Apply Rule: - (-a) = a

-0.8b + 4.1c + 3.2b - 0.1c

  • Group Like Terms

-0.8b + 3.2b + 4.1c - 0.1c

  • Add Similar Elements: -0.8b + 3.2b = 2.4b

2.4b + 4.1c - 0.1c

  • Add Similar Elements: 4.1c - 0.1c = 4c

2.4b + 4c

\boxed{[ \ Eclipsed \ ]}

A number to the 9th power divided by the same number to the 6th power equals 64. What is the number?
Vika [28.1K]
Use an equation:
x^9/x^6=64
x^(9-6)=64
x^3=64
x=4

note that x^9 means "x to the power of 9", same with other ones

the number is 4.
