Answer:
-3/4
Step-by-step explanation:
First, pick two coordinates.
(0,2) and (4,-1)
Then do the rise over run or y/x.
The y is 3 and the x is 4. That is 3/4.
Since the line is going down, it will be negative.
The answer is -3/4.
Answer:6/4
Step-by-step explanation:
Recall that for all t,
cos²(t) + sin²(t) = 1
Now,
x = 5 cos(t) - 7 ⇒ (x + 7)/5 = cos(t)
y = 5 sin(t) + 9 ⇒ (y - 9)/5 = sin(t)
so that substituting into the identity above, we get
((x + 7)/5)² + ((y - 9)/5)² = 1
which we can rewrite as
(x + 7)²/25 + (y - 9)²/25 = 1
(x + 7)² + (y - 9)² = 25
and this is the equation of a circle centered at (-7, 9) with radius 5.
Answer:
It is 6.9
Step-by-step explanation:
6.85565
put
6.85
5 can be rounded up so
6.9 is answer
You can do
83 - 5 to find the answer
So that's
78 or
5 + 78 = 83
