What is the period of y = 8 cos (5pie x + 3pie/2)-9<br> Give an exact value. Units
zzz [600]

\\ \rm\Rrightarrow y=Acos(Bx+C)+D

  • This is the general formula and the period is 2π/B

Now our given function

\\ \rm\Rrightarrow y=8cos\left(5\pi x+\dfrac{3\pi}{2}\right)-9

On comparing we get

  • A=8
  • B=5π
  • C=3π/2
  • D=-9

Period:-

\\ \rm\Rrightarrow \dfrac{2\pi}{B}

\\ \rm\Rrightarrow \dfrac{2\pi}{5\pi}

\\ \rm\Rrightarrow \dfrac{2}{5}

Write an equation of the line that passes me that passes through (2,-5) and is parrallel to the line 2y=3x+10
Otrada [13]

Step-by-step explanation:

parallel means same slope/gradient

2y = 3x + 10

y = 1.5x + 5

let equation be y = 1.5x + b

sub (2, -5)

-5 = 1.5(2) + b

b = -8

therefore y = 1.5x - 8
