Answer with explanation:
We have to prove that, For any integer m, 2 m×(3 m + 2) is divisible by 4.
We will prove this result with the help of Mathematical Induction.
⇒For Positive Integers
For, m=1
L HS=2×1×(3×1+2)
=2×(5)
=10
It is not divisible by 4.
⇒For Negative Integers
For, m= -1
L HS=2×(-1)×[3×(-1)+2]
=-2×(-3+2)
= (-2)× (-1)
=2
It is not divisible by 4.

914.4/ 3
The chef will be able to prepare 3 servings of pasta because if you take one away from a whole number you have 9/10ths so you do that process again you have 2 servings but, you have 2 tenths left over so you add that to the 7 tenths.
Hope this helps :)
Answer:
21 feet
Step-by-step explanation:
Given :
Height of the tripod above the ground = 5 ft
Elevation = 8°
Distance of the tree from the tripod = 120 ft
Therefore from the figure, we can find the height of the tress as:
![$\tan 8 ^\circ = \frac{BC}{AB}$](https://tex.z-dn.net/?f=%24%5Ctan%208%20%5E%5Ccirc%20%3D%20%5Cfrac%7BBC%7D%7BAB%7D%24)
![$0.1405 = \frac{BC}{120}$](https://tex.z-dn.net/?f=%240.1405%20%20%3D%20%5Cfrac%7BBC%7D%7B120%7D%24)
∴ BC ≈ 16
Therefore, CE = BC+BE
= 16 + 5
= 21
Therefore the height of the tree is 21 feet.
