Answer:
(A)
Step-by-step explanation:
Given the three points plotted on a coordinate plane
- (1, 80)
- (2, 20)
- (3, 5)
Let us consider the values in the y-axis i.e. f(x)
80, 20, 5
We notice that each succeeding term occurs by the division of the previous term by 4.
Precisely:
This is a geometric sequence where the:
First Term =80
Common ratio =
Therefore, the function which can be used to graph the geometric sequence is:
ANSWER
B. 3 ft by 8 ft
EXPLANATION
The area is given as 24 square feet.
This implies that,
The perimeter of the rectangular field is given as 22 feet.
This implies that,
Or
We make w the subject in this last equation and put it inside the first equation.
When we substitute into the first equation we get;
This implies that,
When l=3, w=24
Therefore the dimension is 3 ft by 8 ft
