3. a turtle fell to the bottom of a deep well. the turtle climbed up 2 meters on the first day, but slipped back 1 meter as he rested. the second day, the turtle climbed double the distance of the previous day but slipped and lost 1/2 of the day's climbed distance as he rested. this pattern continued until the end of the fourth day, when the turtle realized he was halfway to the top of the well. how deep was the well?

there is no grid

step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

3+x

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
