Write a polynomial that represents the length of the rectangle<br><br> help please !!

disa [49]

Answer:

$\textsf{Length}=0.8x^2-0.7x+0.7\quad \sf units$

Step-by-step explanation:

Area of a rectangle = width × length

Therefore, to find the length of the rectangle, we need to divide the area by the width.

Using long division:

$\large\begin{array}{r}0.8x^2-0.7x+0.7\phantom{)} \\x+0.5{\overline{\smash{\big)}\,0.8x^3-0.3x^2+0.35x+0.35\phantom{)}}}\\-~\phantom{(}\underline{(0.8x^3+0.4x^2)\phantom{-b))))))))))))))}}\\0-0.7x^2+0.35x+0.35\phantom{)}\\ \underline{-~\phantom{()}(-0.7x^2-0.35x)\phantom{-b)))))}}\\ 0.7x+0.35\phantom{)}\\\underline{-~\phantom{()}(0.7x-0.35)}\\ 0\phantom{)}\end{array}$

Therefore, the <u>length</u> of the rectangle is:

$0.8x^2-0.7x+0.7$

Write an equation of the line in point slope form parallel to y=1/3x-5 through point (3,-7)

Mashcka [7]

Hmmm so, parallel lines have the same slope, so a line that's parallel to <span>y=1/3x-5, will also have the same slope as that one, what would that be anyway? </span> $\bf y=\stackrel{slope}{\cfrac{1}{3}}x-5$ , well, low and behold, since that equation is in slope-intercept form already, we can see is just 1/3.
<span>
so, what is the equation of a line whose slope is 1/3 and runs through 3, -7?

</span> $\bf \begin{array}{ccccccccc}
&&x_1&&y_1\\
% (a,b)
&&(~ 3 &,& -7~)
\end{array}
\\\\\\
% slope = m
slope = m\implies \cfrac{1}{3}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-7)=\cfrac{1}{3}(x-3)\implies y+7=\cfrac{1}{3}(x-3)$ <span>
</span>

The U.S. RDA for protein for a girl is 46 g. If a piece of friedchicken contains 23 g, how many pieces would the girl have to ea

Nataliya [291]

The U.S RDA for protein is 46g for girl

If a piece of fried chicken contains 23g

To find the pieces of chicken she is to eat to satisfy the U.S RDA requirement,

The number of pieces of chicken is

$\text{Number of pieces}=\frac{U.S.\text{ RDA g protein required for a girl}}{g\text{ of protein in a piece of chicken}}$

The number of pieces of chicken is

$\begin{gathered} \text{Number of pieces of chicken}=\frac{46}{23}=2\text{ pieces of chicken} \\ \text{Number of pieces of chicken}=2\text{ pieces of chicken} \end{gathered}$

Hence, the right option is B
