The equation that shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Let x represent the time in seconds for the bird feather to reach 10 feet.
Hence:
y = -2x + 10
The equation that shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10

Answer:
31.5 units²
Step-by-step explanation:
Area = ½*base*height
Height of the triangle on the grid = 9 units
Base = 7 units
Area = ½*9*7
Area = ½*63
Area = 63/2
Area = 31.5 units²
Let
represent the number of bacteria after
hours.
so
is the number of bacteria after 0/2 = 0 hours
is the number of bacteria after 1/2 hours
is the number of bacteria after 2/2 = 1 hours and so on
so if we list a few terms of this sequence, we have:
so clearly,
, the number of bacteria after
hours, is equal to
.
is the number of bacteria after
hours.
Thus, we calculate
, which is
.
Answer: the number of bacteria after 24 hours is
.
