I just plugged both equations into my calculator and found where they intersect. But you can do the same on paper by manually finding that intersection in the graph which should be (2,4)

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]

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.

Carlos completed 7 of 10 passes . Ty completed 21of30 compare their pass completion rAtes

ioda

Carlos completed 7 out of 10 passes. In fractional form, this would be 7/10. In decimal form, this would be 0.7. Finally, the percent of passes that Carlos completed was 70%.

Ty completed 21 out of 30 passes. In fractional form, this would be 21/30. In decimal form, this would be 0.7. Therefore, the percent of passes that Ty completed was 70%.

In conclusion, Ty and Carlos completed the same amount of passes, so their pass completion rates are equal, or the same.
