Answer:
3x^2 -x-6
Step-by-step explanation:
If f(x) = 3x^2 - 4 and g(x) = x +2
(f-g)(x)
I like to line them up vertically
3x^2 - 4
-( x +2)
----------------------
Distribute the minus sign
3x^2 - 4
- x -2
----------------------
3x^2 -x-6
Answer:
Percentage Error in counting the marbles in the jar is 39.72%
Step-by-step explanation:
Estimated marbles in the jar = 44
Actual marbles in the jar = 73
⇒Error in Marbles = Number of actual Marbles - Estimated marbles
= 73 - 44 = 29
So, the error in counting marbles in the jar is 29.
Now,
=
or, Percentage Error = 39.72%
Hence, the Percentage Error in counting the marbles in the jar is 39.72%
MLB=104°
AC= 20cm
mLC=
AB =
CB -
Answer:
∠C = 37° ,
AB = 26.54 cm ,
BC= 33.27 cm
Step-by-step explanation:
Given that in triangle ABC
∠A = 39° AC = 20 cm
∠B = 104°
∵ sum of all the three angles of triangle = 180°
So, ∠C = 180° - ( ∠A + ∠B)
∠C = 180° - (39° + 104°)
∠C = 37°
Now Tan 37° =
Or, AB =
So, AB = 26.54 cm
Again, Sin 37° =
So, BC =
Or, BC =
∴ BC= 33.27 cm
Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer
