What is the inverse of the function f(x) = 2x + 1?

Tatiana [17]

We have $y=2x+1$ , to find inverse switch y and x then solve for y.

$x=2y+1 \\ x-1=2y \\ y=\frac{x-1}{2}$ .

Hope this helps.

The Richter scale is used for measuring the magnitude of an earthquake. The Richter magnitude is given R = 0.67log(0.37E) + 1.46

natka813 [3]

Answer:

7.9982

Step-by-step explanation:

-The function for an earthquake's magnitude is given by R = 0.67log(0.37E) + 1.46

-E is energy in kwh.

#For 15,500,000,000 kilowatt hours the magnitude would be:

$R = 0.67\ log(0.37E) + 1.46,\ \ E=15,500,000,000 \ kwh\\\\\therefore R=0.67 \ log(0.37\times 15,500,000,000)+1.46\\\\\\=7.9982$

Hence, the earthquakes magnitude is 7.9982
