Answer:
6656
Step-by-step
Future Amount = [ ](1+__)^[ ]
a₀ = 26
a₁ = 26 * 2 = 26 * (1+1)¹ = 26 * 2 = 52
a₂ = 26 * (1+1)² = 26 * 2² = 26 * 4 = 104 (52*2)
.....
a₈ = 26 * (1+1)⁸ = 26 * 2⁸ = 26 * 256 = 6656
Answer:
y= 2x+7
Step-by-step explanation:
Since the line is parallel to y = 2x - 8 it has slope m= 2
The equation of the line passing through (-4,-1) is given by,






Answer:
Its average speed is 7 units per second.
Step-by-step explanation:
25-4= 21
Distance is 21.
Divide the
, which will be
. 21/3 is 7.
Its average speed is 7 units per second.
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
I would pick C sorry if it’s wrong
