Pls help :) determine which function has a greater rate and explain how you know.
Nesterboy [21]

Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.

<h3>What is an exponential function?</h3>

It is modeled by:

y = ab^x

In which:

  • a is the initial value, that is, y when x = 0.
  • b is the rate of change, as a decimal.

Function 1 is given by:

y = 2(0.2)^x

Hence the rate is b = 0.2.

Considering the values on the table, function 2 is given by:

y = (0.8)^x

Hence the rate is b = 0.8.

Hence, the second function has a greater rate, as 0.8 > 0.2.

Answer:

B: 39 degrees

Step-by-step explanation: The angles in a triangle add up to 180 degrees. 180 - 30 - 24 = 126.

126 = (3x-9).

126 - 9 = 117.

117 / 3 = 39
