Answer:

sin(2x) = 2sinxcosx

cos(2x) = cos2x - sin2x

sin(2x) - cos(2x) = 2 sinx cosx - (cos2x - sin2x)

sin(2x) - cos(2x) = 2 sinx cosx -cos2x + sin2x

ANTONII [103]

Answer:

$F(k)= \frac{9}{5}(k - 273.15) + 32$

Step-by-step explanation:

Given

$F(c)= \frac{9}{5}c + 32$

$C(k) = k - 273.15$

Required

Function from K to F

This implies that, we calculate F(k)

Given that:

$F(c)= \frac{9}{5}c + 32$

Substitute c(k) for c

$F(c(k))= \frac{9}{5}c(k) + 32$

Substitute: $C(k) = k - 273.15$

$F(c(k))= \frac{9}{5}(k - 273.15) + 32$

Hence:

$F(k)= \frac{9}{5}(k - 273.15) + 32$
