Answer:
the required equation is; y = 21 sin(πt/6)
Step-by-step explanation:
Given the data in the question;
Water rises above sea level = 21 ft
Water drops below sea level = 21 ft
so
maximum = 21 ft and also
minimum = 21 ft
Amplitude = ( maximum + minimum ) / 2
Amplitude = ( 21 + 21 ) / 2
Amplitude = ( 21 + 21 ) / 2 = 42/2 = 21 ft
Period = 12 hours
and we know that; period = 2π/b
so
12 = 2π/b
12b = 2π
b = 2π / 12
b = π/6
Standard equation for simple harmonic is; y = asin(bt)
we substitute
y = 21 sin(πt/6)
Hence the required equation is; y = 21 sin(πt/6)
Answer:
It is called the constant ratio.
The conversion is 9*9=81
The conversion is true
Answer: 5/4
Step-by-step explanation:
To get the number of groups of 4/5 are in 1, we divide 1 by 4/5. This will give:
= 1 ÷ 4/5
= 1 × 5/4
= 5/4
<h3>There are 5/4 groups of 4/5 in 1.</h3>
