Can anyone me with this question, it asks which function shows an increasing rate of growth? a. h(x)=99(0.95)x b. h(x)=99(1.05)x c. h(x)=1.05x d. h(x)=0.95x you

Option B

Step-by-step explanation:

An increased rate of growth refers to exponential growth.

Are those of the form "An amount X increases by a 10% every year"

Then, if in year 0 you have X

in year 1 you have X + 0.1*X = X*1.1

in year 2 you have (X*1.1) + (X*1.1)*0.1 = X*1.1*1,1 = X*1.1^2

and in year n, you have X*1.1^n

Then, an increasing rate of growth is usually described by a number bigger than 1 potentiated by the variable; in this case, the correct option is option b:

h(x)=99(1.05)^x  

(where the sign ^ is missing in the question)

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
