Answer:
y = cos (2x + 2π) - 5/2
Step-by-step explanation:
y = a cos (bx + c) +d
a = Amplitude =1
period = 2π/b =π
b= 2
phase shift c/b = π
c/2 =π
c =2π
vertical translation = 5/2 units
d = -5/2 downwards
therefore substituting the values
y=1 cos (2x +2π) - 5/2
y = cos (2x + 2π) - 5/2 ;equation for the function
The answer should be (-4,2)
Answer:
<h2>The rate is 15 minutes per meter.</h2>
Step-by-step explanation:
It takes 9 minutes to fill a depth of
meters.
Filling
meters take 9 minutes time.
Filling 3 meters of the aquarium takes
= 45 minutes time (Multiplying by 5 both the numbers).
In order to<u> fill 1 meter of the aquarium it will take </u>
<u> minutes</u> (Dividing by 3 both the numerical values).
