The absolute value of -a is a:-
its written as |-a| = a
so absolute value of -52 is 52
so 52 has a greater magnitude than 32
Answer: x = ±√145
Step-by-step explanation:
√(17 + x) × √(17 - x) = 12
√(17 + x) (17 - x) = 12
Squaring both sides,
(√(17 + x) (17 - x))^2 = 12^2
(17 + x) (17 - x) = 144
17(17 - x) + x(17 - x) = 144
289 - 17x + 17x - x^2 = 144
x^2 = 289 - 144
x^2 = 145
x = ±√145
Option (A) : least: 10 hours; greatest: 14 hours
The function f(x) = sin x has all real numbers in its domain, but its range is
−1 ≤ sin x ≤ 1.
How to solve such range questions?
Such questions in which every term is in addition and its range is asked is simplest ones to solve if we know the range of each of term. This can be seen from this question
Given: d(t) = 2sin(xt) + 12
= −1 ≤ sin (xt) ≤ 1.
= −2≤ 2 sin (xt) ≤ 2.
= 10 ≤ 2sin (xt) + 12 ≤ 14
= 10 ≤d(t) ≤ 14
Thus least: 10 hours; greatest: 14 hours
