The basic format for an exponential equation is y=ab^x

You know the Initial value is 16 and the decay constant is 0.5:

y=16x0.5^x

Percent increased by: 0.5/16 x 100%
=3.125%

I have attached the graph below.

Sample problem:
Scientists started with an unknown sample. They weighed 16 grams of it. They noticed soon after that the sample was decaying at the speed of 0.5 grams every year. Model an equation.

Hope I helped :)

Mike and Andre want to equally share 46 feet of rope. What amount of rope should each person get? A. 13 B. 36 C. 12 D. 16

Answer:

23 feet

Step-by-step explanation:

According to the scenario, computation of the given data are s follows,

Total rope = 46 feet

Number of person = 2

So, we can calculate the amount of rope each person get by using following formula,

Each person quantity = Total rope ÷ Number of person

By putting the value in the formula, we get

Each person quantity = 46 feet ÷ 2

= 23 feet

Hence, each person gets 23 feet of rope.

Answer:

Step-by-step explanation:

So, we’re probably looking at a n9-m0 cusp, since adding 0 to a number gives a sum lower than adding 9 to a slightly smaller number, something that isn’t true elsewhere in the cycle.

We need a n9 where the sum n+9 is divisible by 3. 9 is divisible by 3 already, so n must be divisible by 3 as well. So, it’s 0, 3, 6, or 9.

Taking as the most likely 3 (because a 39 year old is more likely than a 9 year old, 69 year old, or 99 year old to have a child who doesn’t already know their father’s age) we’ll try 39, 40. 3+9=12, 4+0=4, 12/3=4, this is a possible solution.

Do the others work?

0+9=9, 1+0=1, 9/4=/=1

6+9=15, 7+0=7, 15/4=/=7

9+9=18, 1+0+0=1, 18/4=/=1

1+2+9=12, 1+3+0=4, 12/3=4

there are at least two possibles. the father was correct, the father cannot determine his age from what she has been told, she must guess. From what she knows of him, is it more likely that he’s 39, or 129, or even older?
