Uh, about 50m high, because the pole's height is half that of the shadow, and there is no further info provided, so it is logical to conclude that the same can work for the building as well.
Answer:
<em>The decay rate 'm' is 0.25</em>
Step-by-step explanation:
As given,
Average Life time of New cell phone = 4 years
Lifetime of phone = L = ?
<em>L</em><em> is a random variable defining lifetime of a cell phone.</em>
L∼
Exponential (m)
Mean of Exponential Distribution = 
As, they follow exponential distribution, so to find decay rate , we simply can write it as :
= 4
or

<em><u>m=0.25</u></em>
L∼
Exponential (0.25)
<em>The decay rate is 0.25</em>
For any integer n, all angles -150° n×360° will be coterminal with -150°. The appropriate choices are
-510° . . . . n=-1
210° . . . . n = 1
570° . . . . n = 2
Answer:
See below.
Step-by-step explanation:
- 2x + 3y. Can't be simplified.
- 9x + 6x. Can be simplified. Simplified as 15x.
- 4x + x. Can't be simplified.
- 7y + 1. Can't be simplified.
- 4y + 4x. Can't be simplified.
- y + 2y. Can't be simplified.
