Start with the standard form of a circle, where 
is the center of the circle and 
is the radius.
Plug in the known values.
This is the circle's equation in standard form.
Answer:
SinA = √5/3
CosB = √5/3
Step-by-step explanation:
First let us find the value of a. This is illustrated below:
a^2 = 6^2 — 4^2
a^2 = 36 — 16
a^2 = 20
Take the square root of both side
a = √20 = √(4 x 5) = √4 x √5
a = 2√5
From the diagram,
For sinA
Opp = 2√5
Hypo = 6
Adj = 4
SinA = opp /Hypo
SinA = 2√5/6
SinA = √5/3
For CosB
Opp = 4
Hypo = 6
Adj = 2√5
CosB = Adj /Hypo
CosB = 2√5/6
CosB = √5/3
Answer:
points (0,2) and (5,5)
Step-by-step explanation:
2 points define a line.
the line is in the equation format, y=mx+b
b is the y intercept; in this case, the y intercept is 2 (0,2).
Make your first point (0,2).
Now, use the slope. The slope is rise/run.
Starting from the point (0,2), move to the left five spaces. Then, move up 3 spaces. The second point in that case would be (5,5).
If you're confused, you could also substitute any number you want for x, like, for example, x=5.
y=3/5(5)+2
y=3+2
y=5.
(5,5)
also x=0 (to get the y intercept)
y=3/5(0)+2
y=2
(0,2)
Answer:
30
Step-by-step explanation:
2 + 3 = 6
6 x 10 = 30
30 snowmen
Maybe something like 811.1?
