A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function r(t) = 3t, where t represents time in minutes and r represents how far the paint is spreading.

The flowing paint is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2.

Part A: Find the area of the circle of spilled paint as a function of time, or A[r(t)]. Show your work.

Part B: How large is the area of spilled paint after 10 minutes? You may use 3.14 to approximate π in this problem.

kelsey goes cliff diving into the ocean. Her height as a function of time can be modeled by the function h(t)=-16t^2+480, where t is the time in seconds and h is the height in feet. How long does it take for Kelsey to reach the water?

Answers

Answer:

to differential calculus, because I don't know how to answer this question without

using it.

We're told that Jason's height above the water is  H(t) = -16t² + 16t + 480 .

We can observe many things from this equation:

-- Up is the positive direction; down is the negative direction.

-- The acceleration of gravity is 32 ft/sec² .

-- Jason jumps upward from the cliff, at 16 ft/sec .

-- The cliff is 480-ft above the water.

(This tells us why the question is only concerned with his maximum height,

and then it ends ... 480-ft is one serious cliff, and what happens after the

peak of his arc is too gruesome to contemplate.)

In any case, his vertical velocity is the first derivative, with respect to time,

of his height above the water.

        V = -32 t + 16

At the peak of his arc, where gravity takes over, his velocity changes from

upward to downward, and it's momentarily zero.

                                          0 = -32t + 16

Add  32t  to each side:    32t = 16

Divide each side by  32:      t = 1/2 second

His height at that instant is     H(0.5) = -16(0.5)² + 16(0.5) + 480 =

                                          4-ft above the cliff,  484-ft above the water,

and then he begins falling from that altitude.

The duration of his dive is      484 = 16 t²

                                                  t = √(484/16) = 5.5 seconds

and he hits the water at      V = a t = (32) x (5.5) = 176 ft/sec = exactly 120 mph

I believe it is a, acute isosceles
The answer is A.
An acute angle is very small and thin, while an obtuse angle is wide, usually over 100°
It’s an isosceles because 2 of the sides are even, while an scalene has all 3 different length sides and a Right triangle has one angle that is exactly 90°.

Given △HJK and △RST, what is tan(T)? (help please

Answers

Answer:

C. 12/5

Step-by-step explanation:

∆HJK is similar to ∆RST, therefore, the their trigonometric ratios would be equal to each other.

There,

Tan T = Tan K

Tan K = opp/adj

Tan K = 12/5

Therefore,

Tan T = Tan K = 12/5

Tan K = 12/5

He was tall and sturdy, but his instructors soon discovered that he lacked spirit. He would hide in the woods when the jousting class was called, although his companions and members of the faculty sought to appeal to his better nature by shouting to him to come out and break his neck like a man. Even when they told him that the lances were padded, the horses no more than ponies and the field unusually soft for late autumn, Gawaine refused to grow enthusiastic. The Headmaster and the Assistant Professor of Pleasaunce were discussing the case one spring afternoon and the Assistant Professor could see no remedy but expulsion.No, said the Headmaster, as he looked out at the purple hills which ringed the school, I think Ill train him to slay dragons.He might be killed, objected the Assistant Professor.So he might, replied the Headmaster brightly, but he added, more soberly, we must consider the greater good. We are responsible for the formation of this lads character.Are the dragons particularly bad this year? interrupted the Assistant Professor. This was characteristic. He always seemed restive when the head of the school began to talk ethics and the ideals of the institution.Ive never known them worse, replied the Headmaster. Up in the hills to the south last week they killed a number of peasants, two cows and a prize pig. And if this dry spell holds theres no telling when they may start a forest fire simply by breathing around indiscriminately.Would any refund on the tuition fee be necessary in case of an accident to young Cur-Hardy?No, the principal answered, judicially, thats all covered in the contract. But as a matter of fact he wont be killed. Before I send him up in the hills Im going to give him a magic word.Thats a good idea, said the Professor. Sometimes they work wonders.6.
