9x^{2}  - 180 = 0

9x^{2}  = 180

Divide both sides by 9

 x^{2} = 20

Square root both sides, and you get

x =  \sqrt{20} --\ \textgreater \  simplified: 2 \sqrt{5}

Answer:

The statement provided is True.

Step-by-step explanation:

The exponential function representing growth is given as follows:

y=y_{0}\cdot e^{kt}

Here,

<em>y</em> = final value

<em>y</em>₀ = initial value

<em>k</em> = growth rate

<em>t</em> = time passed

As the function e^{x} is increasing, then the exponential function representing growth is also increasing.

Thus, the statement provided is True.

Mr. Martin's car odometer showed 10,393 miles. His wife's odometer showed 26,481 miles. How many more miles were shown on his wi
bazaltina [42]

Answer:

16,088 more miles

Step-by-step explanation:

Do  26,481-10,393 to get the answer.

26,481-10,393=16,088

The reason that you need to use subtraction to solve this problem is because the word problem says ”how many more”. I’ve learned in school that this is a sign that you have to find the difference to the terms being used in the problem, in this case, 26,481 and 10,393. To find the difference is to subtract the smaller number from the larger number, showing that you have to do 26,481-10,393 to get the answer.
