e^(-∞) = 1 / e^(∞)
= -1/2 · [ 1/ e^(∞) - 1/ e^(∞) ] = -1/2 · ( 0 - 0 ) = 0
About $1.73. Since 378 cost six dollars, The price of one equates to be about 0.0158. Using this knowledge, we can multiply by 109 to get roughly 1.7301
Answer:x = 5
Step-by-step explanation:6 x 5 = 30 and 11 x 5 = 55 + 5 = 60 and we know that the other angle = 90. So, 90 + 30 + 60 = 180. So our answer is x = 5

34 / 40
2 into 34 is 17, and 2 into 40 is 20.
34 / 20 = 17 / 20
No other number can go into 17 and 20
Answer = 17 / 20 to lowest term.
