Answer:

Exponential Functions, eh?

Step-by-step explanation:

First we have to know if it is growth or decay!

(HINT: look inside the parentheses, there's that value I am talking about)

If that value(forgot the variable that was supposed to represent it) is below 1 and above 0, it is decay. If it's greater than 1, it's growth, as the value increases with each larger x-value.

So, It's 0.7, so it's Decay.

The rate of decay depends on the value again. The rate of decay is:

1-Value=Rate Of Decay

So, using substitution:

1-0.7=0.3

And because percents, we have to multiply it by 100 to get our percentage.

0.3*100=30%

(The percentage sign would not come up)

The Rate of Decay is 30%

Hope this Helps!

1.) The numbers 1-12 are written on a card and placed in a bag. What is the probability that a number divisible by 3 is drawn? E
Pepsi [2]

<span>1.) In numbers from 1 to 12, there are  4 numbers that are divisible by 3 (3,6,9 and 12), meaning there will be 4 possible outcomes if a number will be drawn from 12 numbers. The probability of drawing a number divisible by 3 is 4/12 or 1/3.

2.) In the movie drawer, there are 15 movies,  seven are action movies, five comedies, and three dramas. The probability of choosing an action movie is 7/15, while a comedy is 5/15. The probability of choosing an action or a comedy is higher at (7/15+5/15) or 12/15 equivalent to 4/5.
3.) Having drawn 8 black marbles and 2 white marbles from a bag of 100 marbles give a probability of 8/10 (4/5) for black marbles and 2/10 (1/5) for white marbles. If there are 100 marbles, we can predict that there are 4/5(100) equivalent to 80 marbles in the bag.</span>

4.) On a youth soccer team, three out of 12 team members have played in previous years. Based on this information, if 180 kids are in the youth soccer league, then the number of members who could be expected to have played the year before is 3/12 or ¼ of 180 which is 45. </span>

Write the equation of the line that passes throught the point (-4,-9) and has a slope of 1/2
Ray Of Light [21]

Answer: y = 1/2x - 7

<u>Data</u>

Point = (-4, -9)

slope = m = 1/2

<u>Process</u>

To solve this problem, use the formula slope- y-coordinate, substitute the values and simplify.

<u>Equation</u>

 y - y1 = m (x - x1)

       x1 = -4

       y1 = -9

<u>Substitution</u>

y + 9 = 1/2 (x + 4)

<u>Simplification</u>

 y + 9 = 1/2x + 4/2

  y = 1/2x + 2 - 9

<u>Answer</u>

y = 1/2x - 7

How many ways can you write 5^8 as a quotient of two exponential terms? Explain your reasoning.
melisa1 [442]
Exponents can be expressed in terms of quotient or fraction.
For example: x^6 can be expressed as x^8 / x^2 = x^8-2 = x^6.

From the question, 5^8 can be expressed as 
5^10/5^2 = 5^8
(5^2)(5^8) / (5^2) = 5^8
