Situation: A 30 gram sample of a substance that's used to sterilize surgical instruments has a k-value of 0.1257. N= Noekt No = initial mass (at time t= 0) N = mass at time t k= a positive constant that depends on the substance itself and on the units used to measure time t = time, in days​

step-by-step explanation:

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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
