Answer:
Step-by-step explanation:
Consider the angle of depression is same as the angle between horizontal line on the ground and the direct line from the plane to the airport (alternate interior angles).
<u>Use tangent to find the missing length.</u>
tan = opposite / adjacent
- tan 34° = 3200 / x
- x = 3200 / tan 34°
- x = 4744
The distance is 4744 ft
The formula is theta=s/r
r=radius which in this case is 24/2=12cm
s=the arc length
theta is the angle formed by the arc which is 180-45=135
Express 135 degrees in radians and you get 0.75pi
<span>
s=r times theta or 12 (0.75pi)=9pi </span>
the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.
its either:
A. 53.2ft or
B. 44.4
because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say
A.53.2
if this didnt help let me know. and i will delete this (if i can-)
Answer:
You can identify the parent function by making the equation into its simplest form.
Step-by-step explanation:
Remove all transformations from the equation (such as plus/minus signs, constants, and extra terms in the equation).
ex. y= -3x^2+15
The parent function would be y=x^2 after removing everything.
Hope this helps! :)
