Which of the following are equivalent to the function y=3cosx + 2?

check all that apply

note: the ones i highlighted in blue are the answers i've chosen

  your choices are correct

Step-by-step explanation:

sin(x +π/2) is a translation of the sine function to the left by π/2 units, which makes it look exactly like the cosine function that you want.

cos(-x) is the same as cos(x), since the cosine function is an even function.

___

sin(x -π/2) will look like -cos(x), not what you want.

The third choice is a reflection across the x-axis of the function you started with. It is not equivalent.

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
