Answer:

A. f(x): (0,\frac{-1}{3}), g(x): (0,0)

B. f(x): 'y= 0' as horizontal asymptote, g(x): 'x= 4' as vertical asymptote.

Step-by-step explanation:

We are given the functions, f(x)=\frac{1}{x-3} and graph of g(x).

Part A: We know that,

<em>'Y-intercepts are the points where the graph of the function crosses y-axis'.</em>

<em>That is, 'y-intercept is obtained when x= 0'.</em>

So, we have,

When x= 0, f(0)=\frac{1}{0-3} i.e. f(0)=\frac{-1}{3}.

Thus, the y-intercept of function f(x) is the point (0,\frac{-1}{3}).

Also, from the graph of g(x), we see that, the graph crosses y-axis at the point (0,0).

Thus, the y-intercept of g(x) is (0,0).

Part B: We know that,

<em>'Asymptotes are the line or curves approaching the graphs of the functions arbitrarily close'.</em>

Now, as we have the function f(x) is a rational function and the degree of numerator is less than the degree of the denominator.

So, the function f(x) will have 'y= 0' as the horizontal asymptote.

Also, from the graph of the function g(x), we see that,

The line 'x= 4' is the vertical asymptote as it is approaching the graph closely.

So, the function g(x) have 'x= 4' as the vertical asymptote.

Write the following as an expression: How much water do I need to add to l liters of pure alcohol to obtain a solution of 45% al
vredina [299]

Answer:

see below

Step-by-step explanation:

amount of water w

l liter of pure alcohol = 100% alcohol

solution is 45 % percent alcohol

total amount of fluid is w+l

(w+l)( .45) = l*.100

Distribute

.45w  + .45 l = 1l

.45 w = 1l - .45l

.45 w = .55l

w = .55l / .45

w =11/9 l

I need help with this question
nata0808 [166]

I don't know if you've learnt this, but there's something called the KFC rule (you use it when dividing fractions), so k basically stands for keep (so you keep the first fraction), f stands for flip (so you flip the second fraction) and c stand for change (you change the division sign to a multiplication sign)

So you get

5/20*11/5

55/100

which is 11/20

so, an answer of 11/20 would make Quintin correct

A stone dropped from a bridge strikes the water 2.2 s later. How high is the bridge above thewater
mina [271]
Since you are giving no information whatsoever, the formula could be:

S = (1/2)g.t², where s is the distance, 9 =9.8 m/s² and t = time
S = (1/2).(9.8)(2.2)² ans S= 23.7 meters
