Answer:
It's B
Step-by-step explanation:
B) Because Limit as x approaches negative 1 f(x) = –4 and f(–1) = –4, it follows that Limit as x approaches negative 1 f(x)= f(–1). Therefore, the function is continuous at x = –1
10 liters to gallons is 2.6 gallons.
Answer:
384 square units
Step-by-step explanation:
Square prism = Cube
Formula for finding the surface area of a cube = L x L (6)
Surface area = 8 x 8 (6)
Surface area = 64(6)
Surface area = 384 square units
The number of watts which is the power of the turbine for each case is respectively; 600 W; 506.25 W; 300 W
<h3>What is the power of the turbine?</h3>
We are given;
Density of air; ρ = 1.2 kg/m³
Area; A = r² with r being the blade length
Formula for power in turbine is;
P = ¹/₂ρAv³
1) v = 10 m/s and r = 1 m.
Thus;
P = ¹/₂ * 1.2 * 1² * 10³
P = 600 W
2) v = 15 m/s and r = 0.5 m.
Thus;
Power = ¹/₂ * 1.2 * 0.5² * 15³
P = 506.25 W
3) v = 20 m/s and r = 0.25 m.
Thus;
Power = ¹/₂ * 1.2 * 0.25² * 20³
P = 300 W
