Step-by-step explanation:
a) 24.7×52.3=1291.81
On rounding off to 3 significant digits we get
1290
b)
=31.304951
On rounding off to 5 significant figures we get
=31.305
c)
![\sqrt[3]{78} = 4.27265](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B78%7D%20%20%3D%204.27265)
On rounding off to 2 significant figures we get
=4.3
Hence required answers
a)1290
b)31.305
c)4.3
I hope it helped you
Answer A because of the absolute value sign.
First show the statement holds for
. The left hand side is just 8, and the right hand side is
, so it's true.
Assume the statement holds for
, i.e.
and use this to show it holds for
, i.e.
By the assumption above, you have
so the statement is true for all
.
Answer:
m = 2
Step-by-step explanation:
∠ GLI = 90°
∠ GLH + ∠ HLI = ∠ GLI , that is
9m + 25m + 22 = 90
34m + 22 = 90 ( subtract 22 from both sides )
34m = 68 ( divide both sides by 34 )
m = 2
Then
∠ HLG = 9m = 9 × 2 = 18°
