Answer: a) Explicit formula :
b) Recursive formula :
and 
Step-by-step explanation:
Since we have given that
Number of grams of yeast in a culture dish initially = 9 grams
According to question, a certain culture of year increases by 50 % every three hours.
So, the explicit formula will be

And the recursive formula will be

Hence, a) Explicit formula : 
b) Recursive formula :
and 
Congruence Properties
In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!
The Reflexive Property of Congruence
The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.
Okay, this is how you deal with them.
Answer:
F
Step-by-step explanation:
with 5th, you are going to muliply the fraction by 20 to get the answer as a decimal/percent.
0.75=3/4
4/9=0.44 re
6.5=650%
