21 The amount of atmospheric pressure on an object on Earth is 14.7 pounds per square inch. Over time, additional pressure is
exerted on the object. This pressure measured in pounds per square inch, can be represented by the function (0) - 1.1.1.
where tis in minutes.
Which function best describes (O), the amount of pressure in pounds per square inch exerted on the object?

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.

if you was gonna solve for a, a is a   < -12
