Domain of f(x) = pi cos x is ALL REAL NUMBERS.
The range of f(x) = pi cos x is [-1, 1].
Answer:
The correct choice is option B. 3,429
Step-by-step explanation:
When rounded to the nearest hundred, 3429 becomes 3400.
Step-by-step explanation:
5ˣ⁻² = 6
Take log of both sides.
log 5ˣ⁻² = log 6
Use log exponent property.
(x − 2) log 5 = log 6
Solve for x.
x − 2 = log 6 / log 5
x = 2 + (log 6 / log 5)
x = 3.1133
