Answer:
C. c+0.15c
Step-by-step explanation:
Raising her rate by 15% is equivalent to adding 15% of what she charged before to the original price.
The equation of the tangent line of f(x) is given by y = f'(x)x + c
f(x) = 2sin x
f'(x) = 2cos x
At x = pi/3
f'(pi/3) = 2 cos(pi/3) = 1
f(pi/3) = 2 sin(pi/3) = √3
√3 = 1(π/3) + c
c = √3 - π/3
Therefore, required equation is
y = x + √3 - π/3
reduce the index of the radical and exponent with 3, rhen you get your answer, 6
It’s an isosceles triangle, so those two sides are equal:
3x-15=x+33
2x=48
x=24, so BC should be 24.
