Answer:
Point D
Step-by-step explanation:
Answer:
A=B*H
Step-by-step explanation:
multiply B (base) by H (height)
1.3 I think cause that's a percentage
Answer:
Option 1.
Step-by-step explanation:
The height of the tide over the time is shown on the graph.
Its a periodic function (sine graph) plotted on a graph in which variables are
Amplitude a = (6-0)/2 = 3
Period = 15-3 = 12
Therefore b = 2π/period = 2π/12 = π/6
horizontal shift = 0
Vertical shift = 3
Since the function starts with negative sign that means its below the x-axis.
So as per standard formula of f(x) = asin(bx+c)+d
option which matches all these parameters is Option 1. 
Im not giving out direct answers cause math is my weak point but to find the volume multiply the width with the length and with the height all together to find it.<span />
