This is what my math teacher had me write down!
<span>Total power generated doubles every 3 years, so the growth rate is:
(final value / initial value)^(1/years) - 1 = (2 / 1)^(1/3) - 1 = 26%
For the formula, the initial capacity was 92 thousand megawatts, so as a function:
WW = Initial Capacity*(1 + growth rate)^(tt)
WW = 92*(1+26%)^(tt)</span>
Answer:
675
Step-by-step explanation:
3x/10= 1290
Mutiply by 10 for both sides
3x/10*10= 1290*10
Cross out 10 and 10 , divide by 10 and then becomes 3x
3x=12900
divide by 3 for both sides
3x/3= 12900/3
Cross out 3 and 3 , divide by 3 and then becomes x
x= 4300
Answer: x= 4300
The rule for converting sin into cos and vice versa is:
sin α = cos ( 90° - α ) or cos α = sin ( 90° - α )
In this case:
cos ( 6 x ) = sin ( 90° - 6 x )
sin ( 90° - 6 x ) = sin ( 3 x - 9°)
90° - 6 x = 3 x - 9°
90° + 9° = 3 x + 6 x
99° = 9 x
x = 99° : 9 = 11°
Answer: C ) x = 11°
