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.

$2.7^2=2.7\cdot2.7=7.29\\\\3.9^2=3.9\cdot3.9=15.21\\\\2.7^2+3.9^2=7.29+15.21=\boxed{22.50=22.5}$
