Answer:
x = 1 , -6
Step-by-step explanation:
given,
ln (x + 2) = ln (12) − ln (x + 3)
using identity of logarithm
ln (ab) = ln (a) + ln (b)
ln (a) - ln(b) = ln (a/b)
now
ln (x + 2) = ln (12) − ln (x + 3)
ln (x + 2) =
on comparing
(x+2)(x+3) = 12
x² + 5 x + 6 = 12
x² + 5 x - 6 = 0
x² + 6 x - x - 6 = 0
x(x + 6) -1 (x+ 6) = 0
(x - 1)(x + 6) = 0
x = 1 , -6
Hence, the value of x comes out to be x = 1 , -6
- Yes, the height, h(t) of a ball t seconds after it's dropped from the third floor of a building is a function.
- No, table B is not a function because no function can have the same y-values (5) for different x-values (1 and 8).
- Yes, table C is a function because it has different y-values for same x-values.
- Yes, graph D is a function because it has different y-values for same x-values.
<h3>What is a function?</h3>
A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables.
<h3>The types of function.</h3>
In Mathematics, there are different types of functions and these include the following;
- Piece-wise defined function.
For this exercise, we would indicate whether or not each of the above mathematical relation represents a function:
- Yes, the height, h(t) of a ball t seconds after it's dropped from the third floor of a building is a function.
- No, table B is not a function because no function can have the same y-values (5) for different x-values (1 and 8).
- Yes, table C is a function because it has different y-values for same x-values.
- Yes, graph D is a function because it has different y-values for same x-values.
In conclusion, we can infer and logically deduce that a function maps every x-value in a valid domain to a single y-value only.

Answer: dunno
Step-by-step explanation: dunno
3.3 is rational. The decimal doesn't recur, meaning it doesn't go on forever.
3.3 with a dot above the decimal place is recurring, because the dot means that number goes on forever

Answer:
3/10 chance of getting orange
Step-by-step explanation:
1/5 = 2/10
10/10 - 2/10 - 5/10 = 3/10 chance of getting orange
