Answer:33/9
Step-by-step explanation:
Log10(x+3)-Log10(x-3)=1
Log10((x+3)/(x-3))=1
(x+3)/(x-3)=10^1
(x+3)/(x-3)=10
Cross multiply
x+3=10(x-3)
Open brackets
x+3=10x-30
Collect like terms
10x-x=30+3
9x=33
Divide both sides by 9
9x/9=33/9
x=33/9
1 yd is equivalent to 3 ft, so 7 times 3 is 21. 21 is greater than 20, so your answer is 7 yd.
The multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.
<h3>What is an exponential function?</h3>
It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x
where a is a constant and a>1
We have a table that shows an exponential function.
As we know the exponential function:
y = a(b)ˣ
Plug x = 1, y = 6
6 = ab ...1
Plug x = 2, y = 4
4 = ab² ...2
Divide equations 1 and 2
ab²/ab = 4/6
b = 2/3
Plug the value of b in the 1 equation.
a(2/3) = 6
a = 9
y = 9(2/3)×
The multiplicative rate = 9
Thus, the multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.

Answer:
0 1 and 5
Step-by-step explanation:
Not 6 because its an open dot which means that 6 is not included
