<u>Answer:</u>
The value in 3x + 2 = 15 for x using the change of base formula is 0.465 approximately and second option is correct one.
<u>Solution:</u>
Given, expression is
We have to solve the above expression using change of base formula which is given as
Now, let us first apply logarithm for the given expression.
Then given expression turns into as,
By using change of base formula,
x + 2 = 2.4649
x = 2.4649 – 2 = 0.4649
Hence, the value of x is 0.465 approximately and second option is correct one.
Answer:
x=-2
Step-by-step explanation:
Based on the information, the price per soda is 3 dollars. <u>Option D</u>. $3.00 per soda is the correct answer.
<u>Step-by-step explanation</u>:
<u>The given table is</u>:
Number of sodas sold Total money collected
0 $0.00
2 $6.00
5 $15.00
9 $27.00
10 $30.00
From the information given in table, it can be determined that the cost of 2 sodas is $6.
cost of 1 soda = Total cost / number of sodas = $6 / 2 = $3
Similarly,
The cost of 5 sodas is $15, then the cost of one soda = $15 / 5 = $3
The cost of 9 sodas is $27, then the cost of one soda = $27 / 9 = $3
The cost of 10 sodas is $30, then the cost of one soda = $30 /10 = $3
Honestly, nothing further can be done because the expression can't be factored over rational numbers, so it just remains as is: x² + 24.
