See attachment 1. Let ( ) be a bounded sequence. Show that there exists a subsequence of ( ) converging to 2. Show that is not a Cauchy sequence Conclude that diverges.

Two projectiles are shot into the air over a lake. The paths of the projectiles are given by the following equations: (a) y = -0.0013xx + x + 10 and (b) y = - (1/81)xx + (4/3)x + 10 where y s the height and x is the horizontal distance traveled. Determine which projectile travels farther by substituting y = 0 in each equat

If a bank compounds continuously, then the formula is A=Pe^rt, where E is a constant and e = 2.7183. A= 2,000 with continues compounding. How do I round it off to the hundredth place? How long will it take to double my money at 8% interest rate. Don't just give the answer please show how.

Question 1: Write the word name for the number: 6,703,900,090. Question 2: Write this whole number in standard form: One hundred million, six thousand Question 3: Tammy wanted to determine the gas mileage she was getting on her car. She filled the gas tank on her car when the odometer read 49,420 miles.

1. 2/9 = x/4 2. 3x-1/4 + x/2 = 3/8 3. x+3/4 - 2 = 5x-2/5 4. 1/9 + 1/x = 4/9

X+3/X - X+2/X+5 = 1/X A x = 1 B x = -1 C x = 2 D x = -2 E x = 4 F x = -4
