Answer:
New power = 88 Kw (Approx.)
Step-by-step explanation:
Given:
P = a(v³)
Old power p = 700 Kw
Old wind speed v = 12 m/s
Find:
New power when v = 6m/s
Computation:
P = a(v³)
700 = a(12³)
a = 0.4050 m²
New power = a(v³)
New power = (0.4050)(6³)
New power = 87.48
New power = 88 Kw (Approx.)
Answer:
The area of the room and its uncertainty in square meters is:
15.642±0.040 
Step-by-step explanation:
We know the area of a rectangular room is the multiplication of the length and width:

Now we need to know the uncertainty, the uncertainty of a multiplication is:
(1)
: Area uncertainty
: Length uncertainty
: Width uncertainty
A: Area of the room
L: Length
W: Width
Clearing the uncertainty of the area:
(2)


The area of the room and its uncertainty in square meters is:
15.642±0.040 
n + n + 5 = 41 (4) 5n + n + 1 = 41
<em>n and "5 larger than n"
</em>
'5 larger than n' = equivalent to n + 5
We now have n + n + 5
The problem says 41, thus;
<em>n + n + 5 = 41</em>
The answers 4, hope it helps
Answer:
range: -3<x<7
Step-by-step explanation:
The curve of this function starts at x=-3 and ends at x=7, so this function's range is : -3<x<7
