You're almost finished.
(sin/cos) times cos = 0
Look at the left side. You could write it as (sin x cos) / cos = 0
and simply divide numerator and denominator by the cosine (cancel it).
Then what do you have left ? . . . <u>sin(x) = 0</u> Do I need to finish this for you ?
Answer:
90 counterclockwise
Step-by-step explanation:
-2 as x would mean it is in the top left quadrant and going back from a clock would be that one
Answer:
See below
Step-by-step explanation:
<u>Given relationship:</u>
a) r = 3, d = 4
- t = d/r = 4/3 h = 1 h 20 min
b) d = 4 miles, rate = r
- t = 4/r, domain is r and must be greater than zero
c) d = 4 miles, time = t
- r = d/t = 4/t, domain is t and it must be greater than zero
d) t = 3 h, rate = r
- d = rt = 3r, domain is r and can be anything greater than zero
Answer:
96=s*12 or s=96/12 or 12=96/s. but the answer is 8

Answer:
33.1698
Step-by-step explanation:
10
∫ 13y/ y^2-9y-22 .dy
-1
Let's break down the fraction first before we integrate
13y/ y^2-9y-22
= 13y/(y-11)(y+2)
=11/(y-11) + 2/(y+2)
Time to Integrate.
10
∫ 13y/ y^2-9y-22 .dy
-1
=∫ 11/(y-11) dy+ ∫ 2/(y+2) Dy
= 11In(y-11) + 2 In(y+2)
When y = 10
= 11In(10-11) + 2In(10+2)
= 11In1 + 2In12
= 4.9698
When y = -2
= 11In(y-11) + 2 In(y+2)
= 11In(-2-11) + 2In(-2+2)
= -28.2
4.9698+28.2= 33.1698
