Answer:
q = - 14 / 17
Step-by-step explanation:
9 - 17q = 23
-17q = 23 - 9
-17 q = 14
q = - 14 / 17
Answer:
No, because 30 is not equal to 2.5 times 6
Step-by-step explanation:
2.5 times 6 = 15
Sin^(1/2) x cos x - sin^(5/2) cos x
= sin^(1/2) x cos x - sin(1/2)x sin^2 x cos x
factoring we get:
cos x sin^(1/2) x ( 1 - sin^2 x)
Now 1 - sin^2 x = cos^2 x so we have
cos x sin^(1/2) x * cos^2 x
= cos^3 x sqrt sin x
