I need help with what's on the screen, thank you.

a) We know that in the northern Hemisphere we have 4 seasons: Summer where is more sun, Spring, and autumn that the sun is like 50/50 and winter that is the season with less sun. So we can made a graph with this so:

b) In this case if we have a simple interest is going to be a streight light that is going to increase. So the graph will be:

c) An item that increase it's price by 50% is going to be increasing each time more, so this case will be an exponential so the graph will be:

d) The high of a triangle and the base of the triangle are going to to have a constant rate. so the graph will be a horizontal line so:

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

c
