A company tests the life of its rechargeable batteries over six months of use. They test how long a battery will last after a fu

ll charge and put the data into a scatter plot. On the best-fit line y=-12.05+224.26 about how many months will a typical battery last before it is completely dead? Round your answer to the nearest tenth of a month.

Answer:

18.6 months

Step-by-step explanation:

Given that :

Best fit line from scatterplot :

y=-12.05x +224.26

x = Number of month

y = charge on battery

Number of months a typical battery uses before being dead completely :

When battery is dead completely ; charge =0, y = 0

y = -12.05x + 224.26

0 = - 12.05x + 224.26

12.05x = 224.26

x = 224.26 / 12.05

x = 18.610788

Hence, 18.6 months before battery is completely dead.

Try this option:
according to the condition w+l=48 and w*l=95.
Using these two equation:
\left \{ {{l+w=48} \atop {lw=95}} \right. \ =\ \textgreater \  \   \left[\begin{array}{ccc}l=24- \sqrt{481};w=24+ \sqrt{481}\\ \\l=24+ \sqrt{481};w=24- \sqrt{481}\end{array}

The triangles below are similar. Which similarity statements describe the relationship between the two triangles? Check all that
Gekata [30.6K]

<u>Complete Question</u>

In triangle ABC: AC=10 , AB=5., Angle C = 30 degrees.  

In Triangle DEF: ED= 7.5 , DF=15, Angle F =30 degrees , Angle E = 90 degrees.  

Answer:

A, D and E

Step-by-step explanation:

The diagram is drawn and attached below.

  • Triangle ABC is similar to Triangle DEF. (Option E)

Writing it backwards:

  • Triangle CBA is similar to Triangle FED. (Option A)

Also,

  • Triangle BAC is similar to EDF. (Option D).

Therefore, A, D and E are the similarity statements that describe the relationship between the two triangles.

Solve each equation <br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3x-2%7D%7Bx%2B%204%7D%20%3D0%5C%5C%5C%5C%5C%5C%5Cfrac%7B2%7
Sloan [31]

The expression (3x - 2)/(x + 4) = 0 has a value of x is 3/2. Amd the expression 2/(x + 4) = 0 has a value of x is ∞.

<h3>What is simplification?</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

The expression is given below.

(3x - 2)/(x + 4) = 0

Then on simplifying, we have

3x - 2 = 0

    3x = 2

      x = 3/2

And

2/(x - 3) = 0

         2 ≠ 0

More about the simplification link is given below.
