Answer:
(x-9)^2 +(y-12)^2 = 225
Step-by-step explanation:
First find the length of the radius
If is the distance from the center to the point
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt( (0-9)^2 + (0-12)^2)
= sqrt ( 81+144)
= sqrt(225)
= 15
The equation for a circle is
( x-h) ^2+ (y-k)^2 = r^2
(x-9)^2 +(y-12)^2 = 15^2
(x-9)^2 +(y-12)^2 = 225
Answer:
800 grams
Step-by-step explanation:
While converting kg into grams we multiply by 1000
hence
0.8*1000 grams
800 grams
Answer:
260
Step-by-step explanation:
When x represents whole numbers less than 200, the function
f(x) = 2x - 20 .......... (1)
represents the profit earned from selling x carnations for a school fund-raiser.
Therefore, the profit earned from selling 140 carnations for the school fund-raiser will be given by the equation (1) as
f(140) = 2(140) - 20 = 280 - 20 = 260.
Therefore, 260 is the value of f(140). (Answer)
He saved $17.1
