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.

the answer is d. 75%

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

i think the answer is 90 hope this
