Answer: f(x) = 3(0.7)^x
Because as the exponent (x) of 0.7 grows the result decreases. When x is a big negative number the decay is fast, when the x is a big positive number the decay is low, and the function appraches assymptotically to a constant value. This is the behavior of an exponentially decaying function.
Answer:
The perimeter of the playground is 65 metres
Step-by-step explanation:
Questions like this requires attachment; See attachment for diagram.
From the diagram, we have the following parameters


Required
Calculate the parameter of the actual diagram
First, the actual length and width has to be calculated;
Given that the scale drawing is 1:500


Now, the perimeter can be calculated;




However, the question requires answer to be in meters
If 100 cm = 1 m, then


Hence, the perimeter of the playground is 65 metres
The answer is 1/2. 1/5 is equal to 2/10, and 2/10 + 3/10 = 5/10. 5/10 is equal to 1/2 in simpelst form.
The answer would be B) x=5 because 3 times 5 = 15 then add 9 to get 24.
cross multiply to find your answer
x/250 = 20/100
250 X 20= 5000
5000=100x
x = 50
250 - 50 = 200
hope this helps :)
