2. The angle of depression of a car C, from the top of the building of height 100m is
.

a) Calculate the distance between the car and the foot of the building? b) Calculate the angle of elevation of the top of the building from a point D which is 100m from C as shown?​

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
