The magnitude of the Pennsylvania earthquake is 4.
<h3>What is a logarithm function?</h3>
An exponent is a logarithm. You may convert any exponential expression to logarithmic form. As an illustration, if 8 = 23, the base is 2, the exponent is 3, and the outcome is 8. This may be represented as 3 = log2 8 in logarithmic notation.
The equation y=logb(x+h)+k shifts the logarithmic function, y=logbx, by k units vertically and h units horizontally.
Using the formula,
log I₁ / I₂ = M₁ - M₂
M₁ = 7.7, I₁ / I₂ = 4900
log 4900 = 7.7 - M₂
log 4900 ≈ 3.69
On calculating,
M₂ ≈ 4
The magnitude of the Pennsylvania earthquake is 4.

Answer:
25,800
Step-by-step explanation:
-150(4) + 50,000 = 49,400
50(4) + 75,000 = 75,200
75,200 - 49, 400 = 25,800
Answer
(x - 4)
Step by step explanation
To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.
Here (x - 4) is a factor.
Therefore, x = 4
when we plug in x = 4 in the given expression, we get zero.
Let's check it out.
3(4)^3 + 8 (4)^2 - 87(4) + 28
192 + 128 - 348 + 28
348 - 348
0
The answer is (x - 4)
Thank you.
