Answer:

7
-1 2/3
4

Step-by-step explanation:

The average rate of change of a function f(x) on interval [a, b] is the slope of the line through points (a, f(a)) and (b, f(b)). The slope formula tells you that is ...

m = (f(b) -f(a))/(b -a)

1) The rate of change in the interval [1, 2] is ...

rate of change = (2³ -1³)/(2 -1) = (8 -1)/1 = 7

2) rate of change = ((√4 -8) -(√1 -2))/(4 -1) = (-6-(-1))/3 = -5/3

3) rate of change = (11 -(-1))/(5 -2) = 4

Adam is in mexico where the temperature is given degrees celsius . To convert to fahrenheit you multiply the celsius temperature

Anestetic [448]

Answer:

When temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.

Step-by-step explanation:

Let C denotes the temperature in degree Celsius and F denotes the temperature in degree Fahrenheit.

According to the given question,

To convert to Fahrenheit we multiply the Celsius temperature by 9/5 and add 32.

Mathematically it can be written as,

$F=C\times\frac{9}{5}+32$

For example , let us take the temperature in mexico to be 30 degrees Celsius to convert the temperature to Fahrenheit we can use this equation as ,

$F=C\times\frac{9}{5}+32$

Put C = 30, we get

$\Rightarrow F=30\times\frac{9}{5}+32$

$\Rightarrow F=6 \times 9+32$

$\Rightarrow F=54+32$

$\Rightarrow F=86$

Thus, when temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.
