6. Experiments with a covered cup of coffee show that the temperature in °F) of the coffee can be
modeled by the following equation: f(t) = 112e-0. + 68
-0.080
where time (t) is measured in minutes after the coffee was poured into the cup.
_a. [2] What is the temperature of the coffee at the beginning of the experiment?
_b. [1] What is the temperature of the room?
_c. [5] After how many minutes is the coffee 140°F? Give your answer to 3 decimal
places.

f(t)
-0.080
= 112e-0.
+ 68

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
