An animator uses red tiles to design a pattern that grows each second, as shown in this diagram. use the drop-down menus to build functions that describe how the pattern is changing.

s(t) gives the number of tiles in the inner square of the pattern at t seconds.

s(t)= _

a(t) gives the number of tiles added to the outside of the inner square of the pattern.

a(t)= _

p(t) gives the actual number of tiles in the pattern at t seconds.

p(t)=s(t) _ a(t)

p(t)= _

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
