Answer:
1) 81.64 ft 2) 12.56 in
Step-by-step explanation:
a radius is a line <em>halfway</em> through the circle starting in the middle... a diameter is double that, or a line that goes <em>all the way </em>through the circle
you are working with diameter
in order to find the circumference of a circle using diameter, the equation is
C (circumference) = pi x d (diameter)
in order to find the circumference of a circle using radius, the equation is
C = 2 x pi x R (radius)
Answer:
Step-by-step explanation:
125 = 5 *5 * 5 = 5³
8 = 2 * 2 *2 = 2³
125x⁶ - 8 = 5³(x²)³ - 2³
= (5x²)³ - 2³ { a³ - b³ = (a -b)(a² + ab + b²)
= (5x² - 2) ([5x²]² + 5x²*2 + 2²)
= (5x² - 2)(25x⁴ + 10x² + 4)
Hint: (5x²)² = 5² * (x²)² = 25* x²ˣ² = 25x⁴
Answer:
158.4 i think
Step-by-step explanation:
Answer:
All except one interval [-2,8]
Step-by-step explanation:
Notice that the function, wich an hyperbola, has a vertical asymptote in both -2 and 8 and there is nothing between this two values.
So we will exclude what's between them out of the domain.
