Answer:
f(x) = -4x² - 64x - 202
Step-by-step explanation:
We can simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.
f(x) = -4(x+7)^2 - 6
f(x) = -4(x^2 + 14x + 49) - 6
f(x) = -4x² - 64x - 196 - 6
f(x) = -4x² - 64x - 202
1st one is 0
2nd one is -3
3rd one is -2
4th one is 5
Combine like terms, isolate the variable, and make the slope of the variable 1 to find all the answers.
Answer:
B) The earthquake measuring 4.5 on the Richter scale is about 32 times more intense than an earthquake measuring 3.
Step-by-step explanation:
Let Ra = log(Ia/Io), and Rb = log(Ib/Io). Then for ...
Ra - Rb = 4.5 -3.0 = 1.5
log(Ia/Io) -log(Ib/Io) = 1.5 . . . . . . . . . . . substitute the given expressions
(log(Ia) -log(Io)) -(log(Ib) -log(Io)) = 1.5 . . . expand the logs
log(Ia) -log(Ib) = 1.5 . . . . simplify
log(Ia/Ib) = 1.5 . . . . . . . . write as a single log
Ia/Ib = 10^1.5 ≈ 32 . . . . take the antilog
The ratio of intensities is about 32, corresponding to choice B.
