The right answers are

1. C, 1

2. B, an+1 = an x 3, a1 =5

3. C, an = -6 x 0.5^n-1

4. D, an + 2/3 x (1/2)^n-1

5. D, an+1 = an x (-2), a1 = 5

I just took the test and got 100% so these should be correct

What is the value of x when the richter scale rating scale is 8.4?
Vsevolod [243]

The value of x when the richter scale rating scale is 8.4 is 251188643.151

<h3>What is a richter scale?</h3>

A richter scale is a numerical scale that is used for expressing the magnitude of an earthquake in a geographical area

<h3>How the richter scale works?</h3>

The richter scale takes the amplitude of the earthquake's largest seismic as an input and calculate (and display) the magnitude of an earthquake in the geographical area using a logarithmic function

<h3>How to determine the value of x?</h3>

The formula of a richter scale is expressed as:

log(x) = n

Where n represents the scale rating of the scale

In this case, n = 8.4.

So, we have:

log(x) = 8.4

Express as an exponent

x = 10^8.4

Evaluate the exponent

x = 251188643.151

Hence, the value of x when the richter scale rating scale is 8.4 is 251188643.151

Find f(-4) if f(x) = 3x - 6.<br><br> A 6<br> B -6<br> C 18<br> D -18
brilliants [131]

Answer:

f(-4) = -18

Step-by-step explanation:

f(-4)  means x = - 4

So Plug in x = - 4 into f(x) = 3x - 6

f(-4) = 3(-4) - 6

= -12 - 6

= -18

So

f(-4) = -18
