Answer:
Step-by-step explanation:
Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.
tan(x) = 7/24
sin(x)/cos(x) = 7/24
sin(x) = 7/√(7²+24²) = 7/√625 = 7/25
Answer:104
Step-by-step explanation:
To estimate you round the numbers to the nearest whole number
9.7 you round up to 10
3.3 you round down to 3
so 10x3= 30
<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>
4mm
The sides of the new garden can be represented by x+9. x is the original size and 9 is the added 9mm. Multiply the sides to get (x+9)(x+9) or

this will equal the area. Create an equation to solve for the unknown original length.

Take the square root of both sides
13=x+9
Subtract both sides by 9
4=x The original side was 4mm long
