The Richter scale is used to measure the magnitude of an earthquake. The magnitude, R, is given by the earthquake. Determine the

8090 [49]

A) $R=0.65log(0.39E)+1.45

7.5=0.65log(0.39E)+1.45$

B) $6.05=0.65log(0.39E) Subtracted 1.45 from~ both~ sides~ of~ equation.

9.31=log(0.39E) Divided each side by 0.65. 

$

C) $9.31=log(0.39E)

10^(9.31)=0.39E

E=5.24*10^9 kilowatt hours$

What are the solutions of the quadratic equation? 4x^2+9x-9=0

vagabundo [1.1K]

Answer:

$x=3/4$

$x=-3$

Step-by-step explanation:

we have

$4x^2+9x-9=0$

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$4x^2+9x-9=0$

$a=4\\b=9\\c=-9$

substitute in the formula

$x=\frac{-9(+/-)\sqrt{9^{2}-4(4)(-9)}} {2(4)}$

$x=\frac{-9(+/-)\sqrt{225}} {8}$

$x=\frac{-9(+/-)15} {8}$

$x=\frac{-9+15} {8}=3/4$

$x=\frac{-9-15} {8}=-3$
