You must use quadratic formula for each. 

The term in front of the x^{2} is the "a" value in the quadratic formula. The term in front of the x is the "b" value. And the constant term (no x's) is the "c" value. Now you must simply substitute these values into the quadratic formula for each question.

1.) x = -0.268 and x = -3.732

2.) x = -0.838 and x = -7.16

3.) x = 3.56 and x = -0.561

4.) x = 6.70 and x = 0.298

Hope this helps!

Is this right? If not let me know and explain how if u can. <br><br><br> (No link &lt;3)
vlabodo [156]

Answer:

9/35

Step-by-step explanation:

There are a total of 15 bulbs to choose from randomly. First a new bulb is chosen. Chance is 9/15 because 9 out of 15 are new.

Then there are only 14 bulbs left. Then a used bulb is chosen. Chance is 6/14 since 6 out of remaining 14 are used.

Total chance for this to happen is 9/15 * 6/14 = 54/210 = 9/35.

The function A=A_oe^{-0.01155x} A = A o e − 0.01155 x models the amount in pounds of a particular radioactive material stored in
vivado [14]

They are essentially asking us to solve:

357=900e^{-0.01155x} \implies\\ \frac{357}{900}=e^{-0.01155x} \implies\\ \ln{\frac{357}{900}}=-0.01155x \implies \\ x\approx 80.1

Solving this equation for x tells us that it will take around 80.1 years for the materials in the vault to reduce to 357 pounds.
