The cost of one earring is 14.50. Is the tax part of it?
Answer:
C. The given function is continuous at x=4 because the limit is 2.
Step-by-step explanation:
Given the function:
We are to determine if the function is continuous at x=4.
For a function to be continuous at some value c in its domain:
must exist.
Now: at x=4
Since the two values are the same, we say that f(x) is continuous at x=4.
The correct option is C.
The x is 72 because it’s sup
Hello from MrBillDoesMath
Answer: 6.2 feet
Discussion:
The ladder and the wall form a right triangle. The length of the ladder, 20 in this case, is the hypotenuse of the triangle. Let "x" be the distance between the foot of the ladder and the building. Then from trigonometry,
cos (@) = length of adjacent side/ hypotenuse
or in our case
cos(72) = x / 20 => (multiply both sides by 20)
20 * cos(72) = x.
Using a calculator this becomes
20 * ( .3090) = 6.18 feet (approx) or 6.2 feet , rounded to the nearest foot.
Thank you,
