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

It’s is C. 3 because it makes sense
We'll need to assume that this is a case of compound interest which is paid once per year.
Then A = P (1 + r)^t becomes
$737.50 = $500 (1+0.095)^t
Then ($737.50/$500) = 1.095^t
Take the log of both sides. 0.1688 = log 1.095^t, or
0.1688 = t log 1.095 = t(0.0394)
Solving for t, t = 0.1688/0.0394 = 4.28 years
This comes out to 4 years and 28/100 of one year,
or 4 years and 3.36 months, or
4 years, 3 months and 11 days.
Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
