If sin ⁡x=7/25, and 0 < x < π/2, what is cos⁡(x−3π/2)?

Likurg_2 [28]

Answer:

$Cos(x-\frac{3\pi}{2})=-\frac{7}{25}$

Step-by-step explanation:

Remember that $cos(x-y)=cos(x)cos(y)+sin(x)sin(y)$

Then,

$cos(x-\frac{3\pi}{2})=cos(x)cos(\frac{3\pi}{2})+sin(x)sin(\frac{3\pi}{2})\\$

But $cos(\frac{3\pi}{2})=0$ and $sin(x)=\frac{7}{25}$

Then

$cos(x-\frac{3\pi}{2})=cos(x)*0+\frac{7}{25}*sin(\frac{3\pi}{2})\\=\frac{7}{25}*(-1)=\frac{-7}{25}$

PLEASE HELP WILL GIVE BRAINLIEST TO CORRECT ANSWER

ioda

Answer:

Step-by-step explanation:

h(x) = 7 - x - 2x^5

h(-1) = 7 + 1 - 2(-1)^5

h(-1) = 7 + 1 + 2

h(-1) = 10

Now differentiate h(x)

h'(x) = -1 - 2*5*x^4

h'(x) = -1 - 10x^4

h'(x) = -1 - 10(x)^4

h'(x) = -1 - 10 (x)^4

h'(-1) = -1 - 10(10000)

h'(-1) = -1 - 100000

h'(-1) = - 99999
