Refrection over the x-axis changes |x| to -|x|.
Vertical stretch by a factor of 2.5 changes the function to -2.5|x|
Shifting the function down by 3 units changes the function to -2.5|x| - 3
Therefore, f(x) = -2.5|x| - 3
Answer:
Step-by-step explanation:
For this exercise you have to remember the Product of powers property, which states that:
Let be "x" the height in inches of a stack of pennies.
You know that the thickness of 1 pennie is , then, you can write the following proportion:
Solve for "x":
To express this height in Scientific notation the decimal point must be after the first digit, so you must move it one place to the left:
Is the "4" apart of the question? if not then the answer is v=2/9
Answer:
