In what direction and by how many units is the graph of f(x) = −3 cos(2x − π) + 2 vertically and horizontally shifted

MakcuM [25]3 years ago

Answer:

Vertical shift is 2 units top and horizontal shift is \frac{\pi }{2} units to the right

Step-by-step explanation:

Consider the function f(x) = a cos(bx + c) + d.

In this graph, the horizontal shift is -c/b and the vertical shift is d.

Let's compare our graph, f(x) = -3 cos(2x - π) + 2 with this graph.

Here, a = -3, b = 2, c = -π and d = 2.

So, vertical shift = d = 2 units top and

horizontal shift = -\frac{c}{b} =-\frac{-\pi }{2} =\frac{\pi}{2} units to the right.

Step-by-step explanation:

Mechanical advantage can be defined using distances:

Mechanical advantage = input distance / output distance

Or it can be defined using forces:

Mechanical advantage = output force / input force

Solving for the output force:

Output force = mechanical advantage × input force

Plugging in values:

Output force = 2.2 × 202 N

Output force = 444.4 N

What is  3/8f+1/2=6(1/16f-3)
MA_775_DIABLO [31]
\frac{3}{8f}+\frac{1}{2}=6*(\frac{1}{16f}-3) \\\\ \frac{3}{8f}^{(2}+\frac{1}{2}^{(8f}=\frac{6}{16f}-18^{(16f} \\\\ 6+8f=6-288f \\\\ 8f+288f=6-6 \\\\ 296f=0 \\\\ \boxed{f=0}
