Answer:
Slope: -1/3
Y-intercept: -6
Step-by-step explanation:
x + 3y = -18
x+18 = 3y
-3y/-3 = x/-3+18/-3
y = -1/3x - 6
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)
3.14 on the length. but if you add to a graph send another one to my comment and show me

1/2
Step-by-step explanation:
30s = 1/4
30s=1/4
30s=1/4
The area for a rectangle is length × width.
The area for a parallelogram is base × height.
The area for a trapezoid is height (base 1 + base 2) ÷ 2. The area for a rhombus is base × height.
Hope this helps^^ :)
