Answer: 3/4* 56, 0.75 * 56, 3 * 14 I just did the quiz on it
If pounds was x
a. 0.65x is the equation.
2 pounds would cost $1.30
b. 0.65x-0.05x is the equation.
3/8 because to find the area you multiply both numbers so 1*3 is 3 and 2*4 is 8 so your answer should be 3/8
The height of the tide after eight hours is 16 feet.
<h3>How to illustrate the function?</h3>
From the information given, the function is given as 5cos (π/4)t + 11.
In this case, the time is given as eight hours. This will be:
f(8) = 5 × cos (π/4) × 8 + 11
f(8) = 5 × cos(2π) + 11
= (5 × 0.999) + 11
= 16 feet
The height is 16 feet.
