Rather than carrying out IBP several times, let's establish a more general result. Let
One round of IBP, setting

This is called a power-reduction formula. We could try solving for 
explicitly, but no need. 
is small enough to just expand 
as much as we need to.
Finally,
so we end up with
and the antiderivative is
Answer:
m∠DEF = 50
Step-by-step explanation:
∠DEG = ∠GEF
3y + 4 = 5y - 10
subtract 4 from both sides
3y = 5y - 14
subtract 5y from both sides
-2y = -14
divide by -2
y = 7
Add 7 into the equations:
3y + 4 + 5y - 10
3(7) + 4 + 5(7) - 10
21 + 4 + 35 - 10
25 + 25
50
Answer:
-1
Step-by-step explanation:
4x-1=-4
-4+3=-1
Multiply the 4 and 5, and add the exponents
Answer:
Area = 19.05 feet squared
Step-by-step explanation:
By applying sine rule in ΔABC,
sin(∠CAB) = 
sin(60°) = 
BC = 2√3
Area of a parallelogram is given by the formula,
Area = Base × Height
= 5.5 × 2√3
= 11√3
= 19.05 ft²
Therefore, answer is Area = 19.05 ft squared.
