The amount (A) in milligrams of aspirin in a person's bloodstream can be modeled by A = (391t^2 + 0.112)/(0.218t^4 + 0.991t^2 + 1) where t is the time in hours after one dose is taken.

a. A second dose is taken one hour after the first dose. Write an equation to model the amount of second dose in the bloodstream.

b. Write a model for the total amount of aspirin in the bloodstream after the second dose is taken. (The second dose plus the first one)

step-by-step explanation:

times by times

answer: finding the extract measurements and knowing the points

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
