If the tree grows an additional 10 feet, what is the new angle of elevation from the point 25 feet from the base of the tree to the top of the tree? A)42.30
B)47.1°
C)49.8
D)54.6

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:
