The x intercepts are -2 and 5. First, you factor the equation and get (2x+4)(2x-10), then solve for the x's. If you have more problems like this, there's a great online calculator that can help with graphing. www.symbolab.com. It tells you the intercepts if you plug in the equations. Hope this helps!

Answer:

$\sqrt{400 \times 400 - 24 \times 400 - 360 \times 400 - 200} \\ \\ = \sqrt{160000 - 9600 - 144000 - 200} \\ \\ = \sqrt{160000 - 9600 - 144000 - 200} \\ \\ = \sqrt{160000 - 153,800} \\ \\ = \sqrt{6200} \\ \\ = 78.74 \\ \\$

Suppose that the bacteria in a colony grow unchecked according to the Law of Exponential Change. The colony starts with 1 bacter

inn [45]

Answer: There are 2.25×10³⁴ bacteria at the end of 24 hours.

Step-by-step explanation:

Since we have given that

Number of bacteria initially = 1

It triples in number every 20 minutes.

So, $\dfrac{20}{60}=\dfrac{1}{3}$

So, our equation becomes

$y=y_0e^{\frac{1}{3}k}\\\\3=1e^{\frac{1}{3}k}\\\\\ln 3=\dfrac{1}{3}k\\\\k=\dfrac{1.099}{0.333}=3.3$

We need to find the number of bacteria that it will contain at the end of 24 hours.

So, it becomes,

$y=1e^{24\times 3.3}\\\\y=e^{79.1}\\\\y=2.25\times 10^{34}$

Hence, there are 2.25×10³⁴ bacteria at the end of 24 hours.
