Answer:
200
i just know its 200 no explanation
Answer:
1,900 i think is the answer pls dont sue me lol
Sin(15) = 0.258819045103
cos(15) = 0.965925826289
tan(15) = 0.267949192431
all you do is get a graphing calculator input sin(15), then cos(15), and tan(15), make sure the calculator is in degrees not radians hit enter or what ever the answer button is and it should tell you your answer

i = -9
Step-by-step explanation:
4i-5i =10 -1
-i= 9
i=-9
Answer:
17.9 m/s
Step-by-step explanation:
Volume of the slick = 0.5 x π r² h--------------------------------- (1)
Where r = radius of slick
h = thickness of slick, 10⁻⁶m
If 0.5m³ of oil leaked, then the radius of the semicircular slick can be calculated from equation (1)
V = 0.5 x π r² h
0.5= 0.5 x π x r² x 10⁻⁶
r² = 10⁶/ π
r = 10³/√π
dV/dt = πrh dr/dt + 0.5π r² dh/dt----------------------------------- (2)
Asumming the film thickness is constant , equation (2) becomes
dV/dt = πrh dr/dt-------------------------------- (3)
dV/dt = 0.1m³/day
r= 10³/√π
dr/dt= rate of expansion of the slick
Substituting into (3);
0.1 = π x 10³/√π x 10⁻⁶ x dr/dt
dr/dt = 0.1 x 10⁶/ ( π x 10³/√π)
= 17.9479 m/s
≅ 17.9 m/s
