Answer:
77.93
Step-by-step explanation:
#We can simply read off the x,y coordinates directly from the graph.

#we know that a rectangle has pair of two equal sides. To calculate the area, we determine the dimension of any un-equal two sides:
#Using Pythagorean Theorem:

We can therefore calculate area as:

Hence, the area of the rectangle is 77.93
F(n)=1+-7. You put the F as the equation and 1 as the first term plus whatever you add
Dy/dt = dy/dx * dx/dt
dy/dx = 6x^2 - 4
when x = 1, dy/dx = 6 - 4 = 2
dy/dt = 2 * 4 = 8.
Answer:
x=12.8
Step-by-step explanation:
xy / 8 = 16 /10
xy = (8 * 16) / 10
xy = 12.8
This is the answer Period: π; phase shift: x = π
