Answer:

Step-by-step explanation:

Rate of change = the difference in y/the difference in x.

20 - 6.50/4 - 1 = 13.5/3 = 4.5/1

24.5 - 20/5 - 4 = 4.5/1

33.5 - 24.5/7 - 5 = 9/2 = 4.5/1

The rate of change is 4.5.

Explain why x=4 is not in the domain of the function f(x)=√x-5 ?

Since we are dealing with a radical then x - 5 ≥ 0, for real values

x = 4 is less than 5 , hence is not in the domain

Answer:

Length of rectangle = 16 cm

Width of rectangle = 4 cm

Step-by-step explanation:

Given:

Area of rectangle = 64 cm²

Find:

Length and width

Computation:

Assume;

Length of rectangle = a

So,

Width of rectangle = a -12

Area of rectangle = l x b

So,

a(a-12) = 64

a² - 12a - 64 = 0

a² - (16-4)a - 64 = 0

a² - 16a+ 4a - 64 = 0

a (a-16) + 4(a-16)= 0

(a-16)(a+4) = 0

a= 16 , a = -4

So,

Length of rectangle = 16 cm

Width of rectangle = a -12

Width of rectangle = 16 -12

Width of rectangle = 4 cm
