An exponential growth function
A logarithmic growth function
An exponential decay function
A logarithmic decay function
Answers
Answer:
Exponential decay. Your growth factor is 1/8, which is between 0 and 1. Thus, the value is decreasing exponentially.
If the growth factor is greater than 1, you have exponential growth. Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.

When solving: 1,175 ÷ 5, using partial quotients, how would you decide which power of 10, when multiplied by 5, should be subtracted first?
Answers
Answer:
1,165
Step-by-step explanation:
To solve 1,175 ÷ 5 by using partial quotient we should subtracted 10², when multiplied by 5.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The expression is,
⇒ 1,175 ÷ 5
Now,
Solve the expression 1,175 ÷ 5 by using partial quotients as;
5 ) 1,175 (
- 500 100
------
675 135
-675
--------
00
Thus, To solve 1,175 ÷ 5 by using partial quotient we should subtracted 10², when multiplied by 5.

How many 1/8 tps can go into 1/8 cup?
Answers
Answer:
6 tps
Step-by-step explanation:
3 tsp = 1 tablespoons
16 table spoons = 1 cup
therefore 48 teaspoons = 1 cup
therefore 1/8th cup =6 teaspoons
Answer:
(1/8) cup = 6 U. S. teaspoons
Step-by-step explanation:
Do a quick Internet search. Type '1 cup = teaspoons" into the address line as tho' you were doing a search. Result: 1 cup = 48 U. S. teaspoons.
We want to know the teaspoon equivalent of 1/8 cup. To get this, multiply both sides of the above equation by 1/8:
(1/8) cup = (1/8)(48 U. S. teaspoons), or (1/8) cup = 6 U. S. teaspoons.
