Answer:
Domain (Basically means the sets of values of x-axis).Hence, the set of values of domain is given by -3<domain<1. Meaning domain lies between values more than -3 and less than 1.
Range (Basically means the sets of values of y-axis). Hence, the set of values of range is given by -1<range<3. Meaning that range lies between values more than -1 and less than 3.
Function basically means the equation of the given circle. We know that equation of circle is given by;
(x-h)^2+ (y-k)^2 = r^2 [where (h, k) is the center of circle and r is the radius of circle]
From the figure,
(h, k)= (-1 ,1) and r= 2.
So, we can conclude that function is given by equation:
(x-(-1))^2 + (y-1)^2 = 2^2
(x+1)^2 + (y-1)^2 = 4.
y=0.625x+1.75 is the equation for your problem.
Let
Vco------------------- >Volume cone
Vcy------------------ >Volume cylinder
r= 8mm
hco----------- > height of cone=18 mm
hcy------------ > height of cylinder =54-18=36 mm
then
Vco=π*r² *hco/3--------- > π*8² *18/3=π*384 mm³
Vcy=π*r² *hcy--------- > π*8² *36=π*2304 mm³
the total cubic millimeters of sand=Vco+Vcy=π*384+π*2304=π*2688
if 10π cubic millimeters --------------------- > 1 seg
π*2688--------------------------------- X
X=π*2688/10π=268.8 seg
the answer is 268.8 seg
