If the square below is enlarged by a scale factor of 2, what will be the area of the new square? 184 square units 188 square units 192 square units 196 square units
Answers
Answer:
256square units
Step-by-step explanation:
Since we are not given a diagram. Let us assume the side length of the given square is 8 units
If the the square is enlarged by a scale factor of 2, the side length of the new square will be 2 * 8 = 16units
Since area of a square = L²
Hence the area of the new square = 16²
area of the new square = 256 square units
Hence the area of the new square is 256square units
Note that the side length of the original square was assumed. The values can change depending on the side length of the original square before enlargement

Gilbert purchased a car for 34000. The car depreciates at a rate of 14% per year. The exponential function that represents this situation is y = 34000(0.86)^x.
What is the change factor for this function?
Answers
Answer:
.86
Step-by-step explanation:
Exponential function formula
[tex]y = a ( 1 + or - r ) ^t[/tex]
where a = initial value
r = rate of change
and t = number of years
given the equation y = 34000(0.86)^x.
r = .86
Hence the change factor is .86
