Answer:
the length of the string=150.9
Step-by-step explanation:
height of a kite=99 ft
angle of elevation =41
use formula
sin 41= opposite/hypotenuse( opp is the elevation, hypotenuse is the string)
sin 41 = 99/hyp.
hyp.=99/sin41
hyp= (99)/(0.65605902)
hyp.=150.9( rounded to the nearest tenth)
Answer:
Vertical asymptote:x=-4
Horizontal asymptote: y=2
Step-by-step explanation:
The given rational function is
To find the vertical asymptote we equate the denominator to zero and solve for x.
x+4=0
The equation of the vertical asymptote is
x=-4
To find the horizontal asymptote we take limit to infinity. Or simply express the coefficient of x in the numerator over the coefficient of x in the denominator since this is a proper rational function.
The horizontal asymptote has equation
