Answer:
The exponential function y = 2 ^ x has these properties:
A. The domain is the set of all real numbers.
B. The range is zero to infinity, (0, ∞).
C. The graph appears in Quadrants I and II and never touches the x-axis.
D. The function is always positive.
E. The inverse function of y = 2 ^ x is found b)y interchanging x and y here and solving x = 2^y for y: taking the natural log (ln) of both sides, ln x = y ln 2, so that y = (ln x) / (ln 2)
The above (E) can only be done if x is positive.
Answer:
Step-by-step explanation:
Radius r = 15
Circumference = 2πr = 30π cm
Circumference of cone = arc length of sector
= 30π × 216°/360°
= 18π cm
Radius of base of cone = 18π/(2π) = 9 cm
Slant height of cone = radius of circle = 15 cm
Height of cone = √(15² - 9²) = 12 cm
Answer:
20/16
Step-by-step explanation:
4 divided by 16 is 4. so that would mean 4 x 4 = 16, just apply that to 5 and you get 20 because 5x4 is 20.
