Since there are 55 choices, we have to have 55 options, and for 44 questions, we multiply how many options there are in 1 question by 44 to get 55*44=2420
Expected to lose. they initially paid $350 for the tickets and are up charging the price. and the winning price is $100 less.
Step-by-step explanation:
Difference of Squares: a² - b² = (a + b)(a - b)
(x² - 16) / (x - 4)
= [(x + 4)(x - 4)] / (x - 4)
= x + 4, where x =/= 4.
Answer:
x² +y² = 14x
Step-by-step explanation:
Making the usual substitution x = r·cos(θ) and r² = x² +y², we can get there this way:
Substitute cos(θ) = x/r:
r = 14·x/r
Multiply by r:
r² = 14x
Substitute for r²:
x² + y² = 14x
