F the graph of y=ax+b/x+c has a horizontal asymptote y=2 and a vertical asymptote x=-3 then a+c=?
Pachacha [2.7K]
Correct answer is E.

y= \frac{ax+b}{x+c}
\\
\\  \lim_{x \to \infty} \frac{ax+b}{x+c}=2
\\
\\ \lim_{x \to \infty} \frac{ \frac{ax}{x} + \frac{b}{x} }{ \frac{x}{x} + \frac{c}{x} }=2
\\
\\ \lim_{x \to \infty} \frac{a + \frac{b}{x} }{ 1 + \frac{c}{x} }=2
\\ \frac{a + 0}{ 1 + 0 }=2
\\
\\  \frac{a}{1} =2
\\a=2
\\
\\x+c=0
\\-3+c=0
\\c=3
\\
\\a+c=2+3=5

Suppose <br> f(x)=−2x^2+x−2<br> . Compute the following:
Delvig [45]

Answer:

A) – 15

B) – 9

Step-by-step explanation:

f(x)=-2x²+x-2

f(-2)= – 2(-2)²+(-2) – 2 = –2(4) –2–2=–8–4=–12

f(1)= – 2(1)²+(1)-2=–2+1–2= – 3

A) f(-2) +f(1)= – 12 + (–3) = – 15

B) f(-2) - f(1)= – 12 - (–3) = – 12 +3= – 9

I hope I helped you^_^

Radioactive technetium-99m is often used in diagnostic medicine because it has relatively short half-life but lasts long enough
elixir [45]

Answer:

0.08 ml

Step-by-step explanation:

Given that

The half life is 6 hours

The injection is 2.5 ml

And, it remains in the body till 30 hours

We need to find out that how much of the  radioactive material remains in the body

So,

= 2.5 × (1 ÷ 2) ^(30 ÷ 6)

= 2.5 × (1 ÷ 2) ^5

= 0.0781

= 0.08 ml
