How can you tell? (yes, you will have to wait for me to grade, unless you are really lucky with your word choice!)
Question 6
6.
equations have = signs..use the variable given.
Question 7
7.
Remember to round to 3 decimal places...
Question 9
9.
Starting with 200 now, fold variable still n, but equalling B
The graphs show the amounts of medicine in two patients after receiving injections. The circles show the medicine in patient A and the triangles show that in patient B.
One equation that gives the amount of medicine in milligrams, m, in patient A, h hours after an injection, is m=300(\frac{1}{2})^{h}.
What could be an equation for the amount of medicine in patient B?
m=200(\frac{7}{10})^{h}
m=200(\frac{3}{10})^{h}
m=500(\frac{3}{10})^{h}
m=500(\frac{7}{10})^{h}
Select all expressions that are equivalent to 3^{8}.
