So Triangle ABC and ADC are similar (two sides and one angle is equal)so angle CAD = angle ACB =cso angle BAC=2cand in triangle ABCangle BAC + angle ABC + angle ACB = 2c+2c+c = 5c = 180c=180/5 = 36angle BAC =2c=2*36 =72
Answer:
8 plus five is 13..
Step-by-step explanation:
Hours M W F = 4 hours x 3 = 13
Hours S = 8 hours
Total Hours per week = 21 hours
Total made per week = 21 x $10 = $210
F(3) = 9
f'(3) = 3
L(x) = linear approximation to f(x) at x = a
L(x) = linear approximation to f(x) at x = 3
L(x) = f'(a)*(x-a)+f(a)
L(x) = f'(3)*(x-3)+f(3)
L(x) = 3*(x-3)+9
L(x) = 3x-9+9
L(x) = 3x
L(3.02) = 3*3.02
L(3.02) = 9.06
So f(3.02) is approximately 9.06 based on the L(x) linear approximation
g(9) = 3
g'(9) = 5
M(x) = linear approximation to g(x) at x = 9
M(x) = linear approximation to g(x) at x = a
M(x) = g'(a)*(x-a)+g(a)
M(x) = g'(9)*(x-9)+g(9)
M(x) = 5*(x-9)+3
M(x) = 5x-45+3
M(x) = 5x-42
M(9.06) = 5*9.06-42
M(9.06) = 3.3
So g(9.06) is approximately equal to 3.3 based on the linear approximation M(x)
In summary, this means
g(9.06) = g(f(3.02)) = 3.3
which are approximations
The final answer is 3.3
I think the 3rd one idk wait for someone else to answer go compare
