Answer:
Step-by-step explanation:
We are given that is in <em>fourth</em> quadrant.
is always positive in 4th quadrant and
is always negative in 4th quadrant.
Also, we know the following identity about and :
Using \theta_1 in place of \theta:
We are given that
is in <em>4th quadrant </em>so is negative.
So, value of
Answer:
16.5
Step-by-step explanation:
9/100 = x/90
Cross multiply to get 810 = 100x
Divide both sides by 100 to get x = 81 inches
Answer:
The speed of the boat is 20 km/hr
Step-by-step explanation:
Let s be the speed of boat in still water
Let d be the distance
Upstream speed = s-4
Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.
So, Distance traveled in upstream =
Downstream speed = s+4
So, Distance traveled in downstream =
So,
30s-120=20s+80
10s=200
s=20
Hence The speed of the boat is 20 km/hr
The slope would be 2/3 because that would leave pounds when multiplied by cups.
add 0.5 for the weight of the water jug
y = (2/3)x + 0.5
