A vat of milk has spilled on a tile floor. The milk flow can be expressed with the function r(t) = 4t, where t represents time i

Likurg_2 [28]

R(t) = 4t
A(r) = π(r^2)

a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)

b) t = 4,

A(4) = 16*3.14*(16)^2 = 12,861.44

How many leaves on a tree diagram are needed to represent all possible combinations tossing a coin 3 times?

Anika [276]

N = 3 is the number of times the coin is tossed. Since there are 2 outcomes per toss, this means that there are 2^n = 2^3 = 2*2*2 = 8 outcomes total. Therefore, there are 8 leaves total.

If we make
H = heads
T = tails

Then here are the 8 outcomes in the sample space
HHH
HHT
HTH
THH
HTT
THT

Keeven uses 78 feet of fence to make a rectangle pan for his pet rabbit. The length of the pin is 20 feet.What is the width of t

jeyben [28]

Answer:

19 ft

Step-by-step explanation:

The perimeter of a rectangle is given by ...

P = 2(L +W)

Filling in the given values, we have ...

78 = 2(20 +W)

39 = 20 +W . . . . . divide by 2

19 = W . . . . . . . . subtract 20

The width of the rectangular pen is 19 feet.
