Answer:

Work shown below!

Step-by-step explanation:

h(x) = -50x + 450

This is a linear function because it is the form y = mx + b

Graph 2 and scenario A and Table 3

g(x) = 4^x

It is a growth in the graph because the slope is positive

Graph 1 and scenario C and Table 1

f(x) = -16x^2 + 1900

It is a decay in the graph because the slope is negative

Graph 3 and scenario B and Table 2

Answer:

  a) graph 2, table 3

  b) graph 3, table 2

  c) graph 1, table 1

Step-by-step explanation:

a) "At a constant rate" means any graph and table will be a linear function. Only graph 2 is a straight line (linear). Only table 3 matches graph 2.

__

b) As the wrench drops, its height will be decreasing. Only graph 3 is a decreasing function (of the two remaining). Only table 2 matches graph 3.

__

c) Table 1 and graph 1 are the only remaining choices. Happily, they match each other and the scenario.

_____

<em>Additional comment</em>

You can match the tables to the graphs simply by looking at the y-value for x=0.

Three friends each create 4 bags of starter bread dough. After ten days, each of those four bags is then divided into four more
Lapatulllka [165]

Answer:

55 days

Step-by-step explanation:

<u>Number of bags of dough is 192</u>

<u>You have to calculate the number of days.</u>

<em>After 10 days, 4 bags are divided into 4 more bags: 4 + 4 =8</em>

<em>After 20 days: 8 + 8 = 16 </em>

<em>After 30 days: 16 + 16 = 32</em>

<em>After 40 days: 32 + 32 = 64</em>

<em>After 50 days: 64 + 64 = 128</em>

After 55 days: 128 + 64 = 192 (5 days will be considered since it is doubled in 10 days and this time it is divided into half the amount)

Therefore, 55 days pass before 192 bags of dough are created.
