Answer:
Step-by-step explanation:
Let “a” be the first term and ”r” the common ratio of the GP. Then,
f(n) = ar^(n - 1).
f(2) + f(3) = 6f(4). (given)
ar + ar^2 = 6ar^3, or
1 + r = 6r^2, or
6r^2 - r - 1 = 0,
(3r + 1)(2r - 1) = 0.
r = -1/3, or 1/2.
If the common ratio is positive and the second term is 8 we have,
ar = 8, or
a*1/2 = 8, or a = 16.
f(n) = 16*(1/2)^(n - 1) = 2^4*2^(1 - n), or
f(n) = 2^(5 - n).
The first six terms of the GP are : 16, 8, 4, 2, 1, 1/2,…

Checking : f(2) + f(3) = 6f(4), (given).
LHS = 8 + 4 = 12.
RHS = 6* 2 = 12.
LHS = RHS.
[0, inf)
The least y-value the function can have is 0 because the square of a number cannot be negative.
It is D if u did the math right
Answer:y>x, y>2

Answer:
Wind speed
Another very old approach to measure wind speed is through the use of a pressure tube
Microbars per second
Earthquake intensity
The currently accepted method is the moment magnitude scale, which measures the total amount of energy released by the earthquake.
The Richter scale is used to determine the intensity of earthquakes
