Step-by-step explanation:
(1)
=
( cross- multiply )
6p = 8 ( divide both sides by 6 )
p =
= 
(2)
=
( cross- multiply )
7n = 32 ( divide both sides by 7 )
n = 
(3)
=
( cross- multiply )
3x = 20 ( divide both sides by 3 )
x = 
You start at 0 on the unit circle the cos of 0 =1, but at cos 0 there is no angle at all so there is no y value so at cos 0 y=0, 180 is the opposite direction of the starting point which is 0 so the x value of cos180= -1 but there is still no upward or downward angle ie.. y value. so the y value = 0 at 0 and 180. answer is 0
Answer:
5
Step-by-step explanation:
Answer:
3^2/5
Step-by-step explanation:
The equation that matches the given situation is
. So, after two moves, Eric's elevation changed
meters above.
We know that in mathematics, subtraction means removing something from a group or a number of things. What is left in the group gets smaller when we subtract. The minuend is the first element we use. The subtrahend is the part that is being removed. The difference is the portion that remains after subtraction.
Assume that "negative" means climbing down and "positive" means climbing up. We must locate the elevation change in this area.
Given that Eric climbed straight down
meters. So we can write
.
Again Eric climbed straight up
meters. So, we can write
.
Then the change = 
=
=
=
=
=
=
=
Therefore, the equation that matches the given situation is
. So, after two moves, Eric's elevation changed
meters above.
