Answer:

  9x² -5

Step-by-step explanation:

  (f○g)(x) means f(g(x))

Put the definition of g(x) in place of x in the definition of f(x):

  f(g(x)) = f(x²) = 9(x²) - 5

  (f○g)(x) = 9x² - 5

An average African elephant weighs about 9,072 pounds. How is this number written in scientific notation?
qwelly [4]

Answer:9.072×10³

Step-by-step explanation:

A number is said to be written in a scientific notation or standard form if it is expressed in the form a×10n where 1 is less than or equal to a and a is less than 10 and n is an integer

9072 is more than 10

So 9072÷10=907.2

Still 907.2 is more than 10

So 907.2÷10=90.72

Still 90.72 is more than 10

So 90.72÷10=9.072

9.072 is less than 10

We divided 9072 by 1000 and 1000 as a power of ten is 10³

So the answer is 9.072×10³

at the school fair, of the people are under 16 years old. one-third of the people are teachers. if there are at least 21 one tea
Diano4ka-milaya [45]
Hello there!

Your correct answer will be 35 people under 16.

You know that 1/3 of the people are teachers, which means that 2/3 of people are left. Now, you need to get to the decimal value (.667). Make that number 1.667, because there will not be less teachers than students. Now, multiply:

1.667 x 21 = 35

There you go!
