Answer:
C) 12.5
The length of BC = 12.5cm
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that ΔABC</em>
<em>Given that AB = 15cm and ∠A = 40°</em>
<em>we will use trigonometric function</em>
<em> </em><em></em>
<em> </em><em></em>
<u><em>Step(ii):-</em></u>
we know that tan40° = 0.83909
BC = 15 × tan 40°
BC = 12.58649
BC = 12.5cm
<u><em>Final answer:-</em></u>
The length of BC = 12.5cm

Answer:
A. f(x): , 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, 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, i.e.
.
Thus, the y-intercept of function f(x) is the point .
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.
