Answer:
$2310
Step-by-step explanation:
Total cost of fencing = area of fence x cost of fencing per feet
Area of a circle = nr^2
n = 22/7
r = radius = 7
Area = 22/7 x 7^2 = 154
154 x 15 = 2310
Yes, they are proportional. if you divide the second fraction down to simplest form, you get 7/12, which is equal to the first fraction.
y² = 2x ⇒ x =
vertex (0, 0)
focus: ⇒ p = so focus is: ( , 0)
directrix: x =
There's ambiguity here. Either the original expression is "5 times the square root of a" or 5 is the "index of the root."
Then "5 times square root of a" would be 5a^(1/2), or
1/2
5a
. On the other hand, if you meant 5 to be the "index of the root," then the correct result would be
1/5
a
