➷  Work out the original area:

(5 x 18) / 2 = 45cm^2

Increase/decrease the changed values:

18 x 0.7 = 12.6

5 x 1.2 = 6

New area:

(12.6 x 6) / 2 = 37.8cm^2

Calculate percentage change:

((45 - 37.8) / 45) x 100 = 16

16% decrease

The formula below represents Celsius temperature C as a function of Fahrenheit temperature F.
ELEN [110]

Answer:

The inverse represents the temperature F corresponding to a temperature C.

The domain of the inverse function is all real numbers.

194°F

Step-by-step explanation:

Let C= y

y= 5/9 (F - 32),

F= 9/5y + 32

But y= C, hence;

F= 9/5 C +32

The inverse represents the temperature F corresponding to a temperature C.

Given;

F= 9/5 C +32

The domain of the inverse function is all real numbers.

Given C= 90°

F= 9/5 C +32

F= 9/5 (90°) +32

F= 194°F
