Answer 1

Answer:

a = 16

b = $\frac{3}{4}$

Step-by-step explanation:

Length of the design 16 inches is represented by the point (0, 16) and length of 12 inches by (1, 12).

That means these points lie on the graph of the function 'f' represented by,

f(x) = a(b)ˣ

For the point (0, 16),

f(0) = a(b)⁰

16 = a(1)

a = 16

For another point (1, 12),

f(1) = a(b)¹

12 = ab

12 = 16(b) [Since a = 16]

b = $\frac{12}{16}$

b = $\frac{3}{4}$

Therefore, values of a and b are 16 and $\frac{3}{4}$ respectively.
