The equation of a circle with radius r and center at point (a, b) is given by
(x - a)^2 + (y - b)^2 = r^2
1.) For the circle given by x^2 + y^2 = 24
(x - 0)^2 + (y - 0)^2 = (√24)^2
Therefore, center = (0, 0) and radius = √24 = 4.9 units
3.) x^2 + y^2 -10x -2y = -10
x^2 - 10x + (-5)^2 + y^2 - 2y + (-1)^2 = -10 + (-5)^2 + (-1)^2
x^2 - 10x + 25 + y^2 - 2y + 1 = -10 + 25 + 1
(x - 5)^2 + (y - 1)^2 = 16
(x - 5)^2 + (y - 1)^2 = 4^2
Answer: 12cm
Step-by-step explanation:
Answer:
y=1.50x+15
if you are adding the one time fee to the cost of x amount of movies
y=1.50x if you are just looking for the cost to x amount of movies
Step-by-step explanation:
Answer=875miles 17.5miles per gallon
350miles x miles
________=_________
20gallons 50gallons
cross multiply
20x=17500
divide both sides by 20
x=875
875 miles can be traveled with 50 gallons of gas.
To find gas milage, which is essentially miles per gallon, simply divide the number of miles by the number of gallons
350miles 20gallons
350/20=17.5 miles per gallon
Answer:
