Figure shows the length, l, in cm, of a sturgeon (a type of fish) as a functionof the time, t, in years.(a) is the function increasing or decreasing? is the graph concave up or concave down? this function is increasing and the graph is concave down.(b) estimate the average rate of growth of the sturgeon betweent= 5andt= 15. giveunits and interpret your answer in terms of the sturgeon. during this five year period, the sturgeon’s length increased at an average rate of 6 cen-timeters per year.

sorry, i can't understand your question. will later if you describe more clearly!

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
