Answer:

$h^{-1}$ (x) = 2x - 6

Step-by-step explanation:

let y = h(x) and rearrange making x the subject

y = $\frac{1}{2}$ x + 3 ( multiply through by 2 to clear the fraction )

2y = x + 6 ( subtract 6 from both sides )

2y - 6 = x

Change y back into terms of x with x = $h^{-1}$ (x)

$h^{-1}$ (x) = 2x - 6

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:

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

Answer:

Step-by-step explanation:

<h3>7) The lengths of the tangent from an external point to a circle are equal.</h3>

2x - 1 = x + 10

2x = x + 10 + 1

2x = x + 11

2x -x = 11

$\sf \boxed{\bf x = 11}$

8) Radius : XC

Chord: CB

Diameter : AB

Name of the circle: X {a circle is named by its center}
