Cobalt-57 is used in medical testing and has a half-life of about 272 days, which means after 272 days, half of the Cobalt-57 has decayed to a less radioactive and more stable form. The function for the half-life of an
isotope is shown below.
un
A(t) = A,
(3)*
Ao is the initial amount of the isotope, h is the half-life, t is the input or time elapsed, and Aft) is the output or
the amount of the isotope remaining as a function of time.
1. What type of function does this seem to represent? Explain your reasoning using complete sentences. (6

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
