8. Determine the ratio just be dividing 4/3 and then times that by the amount of apples you have 15*1.3 = 20 bananas. Another way to think of it for every 3 apples you have one extra banana so when you have 15 apples you would have 5 extra bananas

What is the decay factor in the exponential decay function y=a (1-r) t

MrRissso [65]

Answer:

in this form, the "-r" would cause the result to decrease

I assume that the answer is "r"

if r = .1 (10 %) then 1-.1 = .9

if you have 100 items then y = 100(.9)^1 = 90

the total decreased by 10% ... y = 100(.9)^2 after 2 time periods

The speed of light is approximately 299,000,000 meters per second.

jek_recluse [69]

Answer:

2.99 x 10⁸ meters per second

Step-by-step explanation:

Scientific notation (also called "Standard form") is written in the form of $a \times 10^n$ , where $1\leq a < 10$ and $n$ is any positive or negative whole number.

To convert a number into scientific notation, move the decimal point to the left or right until there is one digit before the decimal point.

The number of times you have moved the decimal point is the power of 10 ( $n$ ).

If the decimal point has moved to the left, the power is positive.

If the decimal point has moved to the right, the power is negative.

To convert the given number to scientific notation

The decimal point for the given number 299000000 is after the last zero:

⇒ 299000000.

Move the decimal point 8 places to the left:

⇒ 2.99000000

Get rid of the redundant zeros:

⇒ 2.99

Multiply by 10 to the power of the number of decimal places moved:

⇒ 2.99 x 10⁸

Therefore, the speed of light using scientific notation is:

2.99 x 10⁸ meters per second
