Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y = 940(1.89)

 The change represents  growth with 89% of growth rate.

Step-by-step explanation:

The exponential function is given by :-

... (i)

Where , A = initial value , b= multiplicative factor and  x= time period

The given function : .

By comparing this to (i) , we get

b= 1.89 > 1 , thus it represent the growth.

Also,

i.e. Percentage rate of growth = 0.89 x 100 = 89%.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
