The perimeter of an ellipse is given by:
P = (2 * pi) * root ((a ^ 2 + b ^ 2) / 2)
Where,
a: semi-major axis
b: Semi-minor axis
Substituting the values we have:
P = (2 * 3.14) * root (((30/2) ^ 2 + (12/2) ^ 2) / 2)
P = 71.74058266
Round off to the nearest whole number
P = 72 mm

Answer:
Each binder costs 30 cents or $0.30
Step-by-step explanation:
If Sarah's total was $9.05 and the binder costs 7.25 then in order to find the price of the folders you must subtract the cost of the binder (7.25) from the total (9.05) which leaves $1.80 as the amount she paid in total for 6 folders. Next, to find the amount spent per folder divide 1.80 by the number of folders which is 6 and your final answer should be 0.30.
9.25= 7.25+6x (next subtract 7.25 on both sides)
1.80=6x (next divide by six on both sides)
0.30=x
Answer:
<h3>
f[g(x)] = 4x²+6x-3</h3>
Step-by-step explanation:
- f[g(x)]=(2x)²+3(2x)-3...substitute the values of g(x) into the function f(x)
- f[g(x)]=4x²+6x-3...simplified
