equation of circle is given as
where (h,k) is center of cirlce and r is radius.
so lets figure out it from graph.
as we can see in graph center is at ( -1, 1)
radius is 4 units as shown in graph but we can calculate it. take any point on circle and calculate its distance from center. lets take point (3, 1)
now distance = √((3+1)^2+(1-1)^2)
= √16 = 4
lets put it in equation
(x +1)^2 + (y-1)^2 = 4^2
Answer:
<em>The order of subtraction is not important in any of the coordinates</em>
Step-by-step explanation:
Distance Between Two Points
Given two points (x1,y2) (x2,y2), the distance between them is given by the formula
The difference between both coordinates is squared, then added, and finally extracted the square root.
Based on the principle that
and also
We can notice it doesn't matter the sign of a the square of a is always positive. If we had subtracted in the opposite way, the distance would have resulted in exactly the same. In other words, the above formula is exactly the same as
As seen, it applies for both coordinates

Answer:
160
Step-by-step explanation:
The problem statement tells us ...
(# in museum) = 4 × (# waiting)
(# in museum) = 4 × 40 . . . . . . . . . . . . the number waiting is 40
# in museum = 160
15.00 that’s is technically equal to 15 dollars written in decimal
Answer:
- f(5), t=5 Minutes.
- f(60), t=60 Minutes
Step-by-step explanation:
f(t) is the temperature of the yam t minutes after it is placed in the oven.
- In f(5), t=5 Minutes, therefore f(5) is the temperature of the yam 5 minutes after it is placed in the oven. At f(5), the yam is still in the oven since it is not yet up to 45 Minutes.
- In f(60), t=60 Minutes, therefore f(60) is the temperature of the yam 60 minutes after it is placed in the oven. Since the yam is taken out after 45 minutes, at f(60), the yam is no longer in the oven.
