Answer:
cos A = 12/13 = 0.9231
(angle A = 22.62°)
Step-by-step explanation:
cos A = 12/13 = 0.9231
<span>2.607 x 10^13 dollars per person.
Avogadro's number is approximately 6.0221409x10^23.
So divide by the 231 million people. Giving
(6.0221409 x 10^23) / (231 x 10^6) = 0.02607 x 10^17
= 2.607 x 10^15 pennies
But we want dollars, so divide by 100
2.607 x 10^15 / 100 = 2.607 x 10^13 dollars</span>
It is irrational and is = to 4√2
Answer:
-1
Step-by-step explanation:
Assuming problem is: x->2 (x^3 -3x^2 +3)
Since the expression is continuous at x=2,
then the limit can be found just by evaluating the expression at x=2.
2^3-3(2)^2+3
8-3(4)+3
8-12+3
-4+3
-1
