Answer:
So after the second tablet there is 360-mg of drug in the body.
So after the third tablet there is 372-mg of drug in the body.
Step-by-step explanation:
We know that a doctor prescribes a 300-mg antibiotic tablet to be taken every eight hours. Just before each tablet is taken, 20% of the drug remains in the body.
We know that 20%=0.2.
We conclude that after the first pill, 300mg of the drug is in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the second tablet:
So after the second tablet there is 360-mg of drug in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the third tablet:
So after the third tablet there is 372-mg of drug in the body.
Answer:
Point A: (4, -3)
Point B: (3, -12)
Point C: (-1, -5)
Step-by-step explanation:
Reflection of point A:
The x will stay the same and only the y will change.
Take the y-coordinate and subtract it from the reflection line while getting the absolute value..
|(-1) - (-2)| = |1| = 1
This means, point A is one unit down the line y = -2
(-2) - 1 = -3
The coordinate for A will now be (4, -3).
Reflection of point B:
Again, the x will stay the same and only the y will change.
Using the absolute value, get the y-coordinate and subtract it from the reflection line again..
|(8) - (-2)| = |10| = 10
This means, point A is five unit down the line y = -2
(-2) - 10 = -17
The coordinate for B will now be (3, -12).
Reflection of point C:
I think you get the gist of it.
|(1) - (-2)| = |3| = 3
(-2) - 3 = -5
The coordinate for C will now be (-1, -5).
I added an image down below of what the reflection looks like. Sometimes it helps to see things visually.
The red triangle is the original image and the blue triangle is the image after the reflection. The purple line is the reflection line y = -2
Hope this helped!
