Answer:
D. large
Step-by-step explanation:
Substitute x= 3 and calculate
f(3)= 2•9+5• sqrt( 1)
f(3)= 18+5= 23
L= lenght. w=width
l=12+w
Area= lw
Area=(12+w)w
Area=12w+w^2
note:w^2 means w to the power of 2
good luck;)
T ∫ 1/√(1 - x²) dx = arcsin(x)
<span> ∫ 1/√(1 - x²/a) dx = √a arcsin(x/√a) </span>
<span>So pull a factor of 5 out of the square root to get </span>
<span>1/5 ∫ 1/√(1 - 16 x²/25) dx </span>
<span>= 1/4 arcsin(4 x/5)</span>
