So if we have a right triangle with a 19ft hypotenuse or ladder, and it makes a 73deg angle with the ground. So we can use the sine of the angle to find the height.
sin(73)=y/19 y=19sin(73) y=18.2ft is the height
Hope this helps. Any questions please just ask. Thank you.
Because the equation does not have any variable other than the x for the exponent. The domain would be all real numbers even ones less than 1/2 so the answer is False
