Answer:
103.67 dollars.
Step-by-step explanation:
The perimeter of the garden = 2 * π * 6 feet.
So the cost is 2.75 * 12π dollars.
= 103.67 dollars.
Answer:
8.66666666666 (11)
Step-by-step explanation:
2 divided by 3 -.666666666666666
4 times 3 is 8
Answer:
90% of the question answered correct
10% were incorrect
Step-by-step explanation:
The answer is B.
you add up all of the coins (all colors) and get thirty. which mean you have
?/30
if he draws 8 that is your numerator so you now have
8/30
after you get this you simplify so in this case you can simplify by 2. (simplifying is divine the top and bottom by the same number equally)
after you simply you get 4/15 (8÷2=4. 30÷2=15)
Substitute
so that
.
Then you have
Expand the denominator and simplify.
where the last simplification only holds for certain intervals.
Then the integral is
To compute the remaining integral, use the Pythagorean expansion for
:
Now substituting
so that
allows you to rewrite the integral as
Back-substitute:
Simplify the trigonometric terms. Your reference triangle involves an angle with the side opposite the angle having length
and the side adjacent to it having length
. This means the missing length is
.
The secant ratio for this angle is then
.
So the antiderivative is equivalent to
