Given the following exponential function, identify whether the change represents
elixir [45]

Answer:  The change represents  growth with 89% of growth rate.

Step-by-step explanation:

The exponential function is given by :-

f(x)= Ab^x... (i)

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

  • We call 'b' growth factor when b>1, we can write b= 1+r , where r is the rate of growth.
  • We call 'b' decay factor when b<1 , we can write b= 1-r , where r is the rate of decay.

The given function : y = 940(1.89)^x.

By comparing this to (i) , we get

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

Also,

b= 1+r\Rightarrow\ 1.89 = 1+r\\\\\Rightarrow\ r=1.89-1=0.89

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

Marni and Sharika partnered together in a dance-a-thon to raise money for the Humane Society. Marni raised $18 plus $0.80 per mi
Snowcat [4.5K]
I'm assuming that the 3434 is a typo error. It should be 34.

Marni: 18 + 0.80m
Sharika: 12 + 0.9m

x = Sharika's minutes
x + 34 = Marni's minutes

[18 + 0.80(x+34)] + [12 + 0.90(x)] = 264
18 + 0.80x + 27.2 + 12 + 0.90x = 264
0.80x + 0.90x = 264 - 18 - 27.2 - 12
1.70x = 206.80
x = 206.80/1.70
x = 121.65 or 122 

x + 34 = 122 + 34 = 156 minutes.
