1. Ms. Mullins attaches herself to a strong bungee cord and jumps off a bridge. At time t = 3 sec, the comedy first becomes taut. From that time on, Mullins' distance, d feet, from the water below the bridge is given by the
following equation: d =-80(sin[1.2(t – 3)])+90. d=80(sin [1,2]) +90
How far is Mullins from the water when t = 4?

b. Find the average rate of change for the interval t= 3.9 to t = 4 sec, and for the interval t = 4 to
t= 4.1 sec.

c. Estimate the instantaneous rate of change at 4 sec.

e. Give the equation of the tangent line to the graph at 4 seconds.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
