Cheetah = 70mph
70 miles x 1 hour x 1760 yards (yds) = 32.4 yds/sec
Fox = 42mph
42 miles x 1 hour x 1760 yards = 20.5 yds/sec
Sorry, I can only answer the first part
Answer:
<h2>x³ + x² - 3x - 3</h2>
Step-by-step explanation:
I'm assuming g*f means g times f, so you want to multiply the two functions together.
(x² - 3)(x + 1) Since the product is 2 binomials, use FOIL
= x²(x) + x²(1) - 3(x) - 3(1)
which simplifies to
<h2>x³ + x² - 3x - 3</h2>
That is the answer. hopefully I can help you.
