Answer:

Look at the picture

Step-by-step explanation:

\log_ab=c\iff a^c=b\\\\\text{Therefore}\\\\f(x)=b^x\to y=b^x\\\\\text{find}\ f^{-1}(x).\ \text{Exchange}\ x\ \text{and}\ y\ \text{and solve for}\ y:\\\\b^y=x\qquad\text{logarithm iwth base b of both sides}\\\\\log_bb^y=\log_b(x)\qquad\text{use}\ \log_ab^m=m\log_ab\\\\y\log_bb=\log_b(x)\qquad\text{use}\ \log_aa=1\\\\y=\log_b(x)\\\\f^{-1}(x)=\log_b(x)\to g(x)=f^{-1}(x)\\\\\text{Then:}\ f(a)=b\to g(b)=a

1. Edgar measures the temperature of a solution at the beginning of an experiment to be 23°F . He monitors the
PIT_PIT [208]

The average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.

To A) write an expression that represents the average change in temperature each minute, and B) if Edgar repeats the experiment and finds the average change in temperature each minute is 1 ° F greater in the second trial than in the first trial, to determine what is the average change in temperature each minute in the second trial of the experiment, the following calculations must be performed:

A)

(-2 x 4 + -3 x 3 + 6) / 10 = X

(-8 + -9 + 6) / 10 = X

-11 / 10 = X

-1.1 = X

B)

(-3 x 4 + -4 x 3 + 7) / 10 = X

(-12 + -12 + 7) / 10 = X

-17/10 = X

-1.7 = X

Therefore, the average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.

A newspaper stand sold 1,000 copies of the city newspaper for $1,600 write and solve an equation to find the price of one copy
Vsevolod [243]

Answer: \$1.6

Step-by-step explanation:

Let be "x" the price in dollars of one copy of the city newspaper.

You need to analize the information provided in the exercise:

1. The total number of copies of the city newspaper sold in the newspaper stand is:

Total\ copies=1,000

2. The amount of money earned by selling 1,000 copies of  the city  newspaper is:

Total\ earned=\$1,600

Then, you can determine that the value of "x" can be found with:

x=\frac{Total\ earned}{Total\ copies}

3. Finally, substituting values, you get:

x=\frac{\$1,600}{1,000}\\\\x=\$1.6
