Hayden is growing bacteria in two different solutions. Both populations start with a single bacteria. She records the number of

bacteria in each solution every hour.
The population in solution A is modeled by the sequence An=22n, where n is the number of hours.

The population in solution B is modeled by the sequence B0=1, Bn=Bn−1+4, where n is the number of hours.

Are the sequences An and Bn functions? Why or why not?

Simplify sqrt 8y/sqrt y
Eddi Din [679]

\frac{\sqrt{8y} }{\sqrt{y} }

Answer:

2\sqrt{2}

I turned the numerator into an exponent: 2 \frac{3}{2}

\frac{2^{\frac{3}{2}}\sqrt{y}}{\sqrt{y}}

The \sqrt{y} will cancel out, leaving 2 \frac{3}{2}.

2^{\frac{3}{2}}=2\sqrt{2}

<em>Hope this helps!!!</em>

Answer:

Solution given:

(x_1,y_1)=(7,11)

(x_2,y_2)=(13,17)

now

slope:\frac{y_2-y_1}{x_2-x_1}=\frac{17-11}{13-7}=\frac{6}{6}

Write the equation of the line that passes through (-3,6) with a slope of -2

\diamond\large\blue\textsf{\textbf{\underline{Given question:-}}}

       What is the equation of the line that passes through (-3, 6) and has a slope of -2?

\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}\diamond

     

First, we need to write the equation of the line in point-slope form:-

\sf{y-y_1=m(x-x_1)}

Replace y1 with 6, m with -2, and x1 with -3:-

\sf{y-6=-2(x-(-3)}

On simplification,

\sf{y-6=-2(x+3)}

On further simplification,

\sf{y-6=-2x-6}

Add 6 on both sides:-

\it{y=-2x}

<h3>Good luck with your studies.</h3>
