A rescue helicopter is stationed at a point X. An emergency call is received and the helicopter flies 16km on a bearing of 040 degrees to point Y. A second emergency call is received and the helicopter then flies 30km on a bearing of 115 degrees to arrive at point Z. The helicopter flies back to point X. a) work out the distance that the helicopter has to fly from point Z to point X. give your answer correct to 3 significant figures. b) work out the bearing on which the helicopter has to fly to from point Z to point X. give your answer as a three-figure bearing.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

the ordered pairs for the given function are of the form

one triangle is 2.5 times bigger than the other triangle.
