Hi there, first we change the mixed numbers into improper fractions, 9 5/9=86/9 and 6 5/6=41/6. Second, we solve the problem now. 86*6-41*9÷9*6, 516-369/54=147/54. Third, we simplify 147/54 into 49/18. Fourth, we make 147/54 into a mixed number. 147/54 as a mixed number is 2 13/18
Answer:
Step-by-step explanation:
To find the values of the angle which makes maximum r you use the derivative of r

If you equals this derivative to zero you obtain the value of the angle:

However, the values of 5π/6 and 9π/6 are also available, because makes the sinusoidal function equal to 1.
hence, the answer is:

answer b
Answer:
33
Step-by-step explanation:
4.75=4+0.75
0.75=0.75/1=7.5/10=75/100=3/4
4 and 3/4
2x^2 - 8 = 0
2x^2 = 8
x^2 = 8/2 = 4
x = sqrt(4) = 2 or -2
