Complete question is;

The function f(x) = (9/5)x + 32 converts temperatures from x degrees in Celsius

to y degree in Fahrenheit. The function g(x) = (5/9)(x − 32) converts temperatures from x degrees in Fahrenheit to y degrees in Celsius.

a. Find (f o g) (x)

b. (g o f) (x)

Answer:

A) x

B) x

Step-by-step explanation:

A) f(x) = (9/5)x + 32

g(x) = (5/9)(x − 32)

Thus;

(f o g) (x) = (9/5)(g(x)) + 32

This gives;

(9/5)((5/9)(x − 32)) + 32 = x - 32 + 32 = x

B) (g o f) (x) = (5/9)((f(x)) − 32)

This gives;

(5/9)((9/5)x + 32 - 32) = x

If a plane crashes on the border of Mexico and the U.S, where would you bury the survivors by the law?
lyudmila [28]

Answer:

Step-by-step explanation:

So, since when do we start burying survivors alive? Did they crash into Zombiland? Was it Spirit Air who didn’t want to pay damages in law suits? Or is this a time distance question in which we have to wait until each of the surviving passengers pass away? If so then I suspect that those who survived the New Mexico/Texas border crash would be buried in the state or country in which they eventually died or where they so instructed their next of kin to bury them. Of course, maybe they would be cremated and then the ashes will sit on someone’s mantel until a house cleaner tosses them out or they ashes may be spread out over a special parcel of land or water.

Which equation represents a population of 210 animals that decreases at an annual rate of 14%
soldi70 [24.7K]

Answer:

The equation i.e. used to denote the population after x years is:

P(x) = 490(1 + 0.200 to the power of x

Step-by-step explanation:

This problem could be modeled with the help of a exponential function.

The exponential function is given by:

P(x) = ab to the power of x

where a is the initial value.

and b=1+r where r is the rate of increase or decrease.

Here the initial population of the animals are given by: 490

i.e. a=490

Also, the rate of increase is: 20%

i.e. r=20%

i.e. r=0.20

Hence, the population function i.e. the population of the animals after x years is:

P(x) = 490(1 + 0.200 to the power of x
