Answer:

<h2><u>D ) 27,000; exponential</u></h2>

Step-by-step explanation:

y = A(b) ^ t

 A: initial amount

b: growth rate

t: time y = 1000 * (3) ^ ((1/8) * t)

For 24 years we have: y = 1000 * (3) ^ ((1/8) * 24) y = 27000

For this case we have a function of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: growth rate
 t: time
 Substituting values we have:
 y = 1000 * (3) ^ ((1/8) * t)
 For 24 years we have:
 y = 1000 * (3) ^ ((1/8) * 24)
 y = 27000
 Answer:
 
D) 27,000; exponential

Answer:

SAS Postulate

Step-by-step explanation:

You can use the SAS (side, angle, side) postulate that says "if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent"

Side AB is proportionate to DE and

Side AC is proportionate to DF.

Angle A and Angle D are the same; and is between the two sides

I hope this helps.

The answer is A.  because for you to find the answer you have to subtract so it would be 55.75-12.5=43.25
