You are multiplying 2 to each term each time.
-40 is the 4th term
-40 x 2 = -80
-80 x 2 = - 160
-160 x 2 = -320
-320 x 2 = -640
-640 x 2 = -1280
-1280 x 2 = -2560
-2560 x 2 = -5120
-------------------------------------------------------------------------------------------------------------------
-5120 is your 11th term.

hope this helps
Answer:
assuming the comma is meant to be a decimal...
It would be 2.9
Step-by-step explanation:
the place right after the decimal is the tenth place. the 5 rounds up the 8. don't worry about the 2. so the 8 becomes a 9 and you leave off the rest because you are only worrying about the tenths place.
1 mile is equal to 5280 feet.
5/5 - 2/5 = 3/5 of a mile left to walk
3/5m * 5280 ft/1m = (3m*5280ft)/(5*1m) = 15840ft/5 = 3158 feet left to walk to get to work.
Or
5280 feet / 5 = 1056 ft * 2 = 2112 ft walked to get to work
5280 - 2112 = 3168 feet left to walk to get to work.
The distance between point on the ground from the top of the building is 396 meter, if the building is 280 m high and The angle of depression from the top of a building to a point on the ground is 45 degrees.
Step-by-step explanation:
The given is,
The angle of depression from the top of a building to a point on the ground is 45 degrees.
Height of the building is 280 meter.
Step: 1
Given diagram is a right angled diagram,
For right angle triangle,
90° = 45° + 45°
= 90°
Trignometric ratio,
sin ∅ =
....................(1)
For the above ratio take the bottom angle, that is angle of depression from the top of a building to a point on the ground is 45 degrees.
Where, Opp side = 280 meters
Hyp side = x
∅ = 45°
Equation (1) becomes,
sin 45° = 
0.70710678 = 
x = 
x = 395.979
Distance between point on the ground from the top of the building, x ≅ 396 meter
Trignometric ratio,
cos ∅ =
Cos 45 =
Adj = (0.70710678)(396)
Bottom length, Adj = 280 meter
Result:
The distance between point on the ground from the top of the building is 396 meter.
