Answer:
97.2 m
Step-by-step explanation:
=
= 19.4 m/s
Distance = speed x time = 19.4 m/s x 5 s = 97.2 m
A circle with radius 4 inches is inscribed in an equilateral triangle. Find the area of the triangle.
1 answer:
The inscribed circle has its center at the point of intersection of the angle bisectors, which also happen to be the medians. Hence the altitude of the triangle is 3 times the radius, or 12 inches.
The side length of this triangle is 2/√3 times the altitude, so the area is
... Area = (1/2)·b·h = (1/2)·(24/√3 in)·(12 in)
... Area = 48√3 in² ≈ 83.1384 in²

Step-by-step explanation:
The domain of a function are the values of that you can plug into the function
.
Values inside of a root must be non-negative, which means that must be greater than or equal to zero. We can set up an equation to find the domain:
With this, we know the domain of the function is .
The range of a function are the values that can have. Since the equation is a cube root, the value will always be non-negative, meaning the range of the function is
.
