For
y=a(x-h)^2+k
vertex is (h,k)
a tells about the graph

y=-2(x-(-2))^2-(-8)
vertes ix (-2,-8)

to graph, plot some points
when x=0, then y=-16
(0,-16)
when x=1, then y=
(1,-26
when x=-1, then y=-10
(-1,10)
when x=-3, y=-10
(-3,10)

One scientific team determened that the avrage thickness of a chickens egg shell is 0.311 millimeters
rosijanka [135]

Answer:

As we can see the average for the thickness of a chickens egg shell is 0.311 mm and if we want to round this number to the nearest tenth we just need to see the second decimal place and round to one decimal place.

This second decimal place for this number is 1 and this number is \leq 5 so then if we round to the nesrest tenth we will get:

0.3 mm

Step-by-step explanation:

We use the following info in order to complete the qeustion:

Round the thickness of the shell to the nearest tenth.

0.3

0.5

Find a fraction equivalent to 5/7 whose squared terms add up to 1184.
bogdanovich [222]

The system of equations of two unknowns is formulated and solved.

\large\displaystyle\text{$\begin{gathered}\sf \bf{ \left\{\begin{matrix} \ \ \ \dfrac{x}{y} = \dfrac{5}{7} \\ x^2+y^2 = 1184 \end{matrix}\right. \ \Longrightarrow \ x=\dfrac{5}{7}y  } \end{gathered}$}

\large\displaystyle\text{$\begin{gathered}\sf \bf{ \left (\dfrac{5}{7}y \right )^2+y^2=1184\ \Longrightarrow\ 25y^2+49y^2=58016 } \end{gathered}$}

                                                              \large\displaystyle\text{$\begin{gathered}\sf \bf{74y^{2}=58016} \end{gathered}$}\\\large\displaystyle\text{$\begin{gathered}\sf \bf{ \ \  \ \ \ \ y^{2}=784 } \end{gathered}$}\\\large\displaystyle\text{$\begin{gathered}\sf \bf{ \ \ \ \ \ y=\pm\sqrt{784}=\pm28  } \end{gathered}$}

                                                                  \large\displaystyle\text{$\begin{gathered}\sf \bf{ x=\dfrac{5}{7}(\pm 28)=\pm 20  } \end{gathered}$}

The fraction that satisfies the request is \bf{\dfrac{20}{28}} , since in \bf{\dfrac{-20}{-28}} the negative signs are canceled and the first fraction is obtained.

Mhanifa u helped me with this question.... U said it was 25 and its not so why is it wrong
Yanka [14]

Hey I don't know who Mhanifa is but 25 is correct, and I will put the entire explanation to how to get the answer here.

First of all the 2 lines on the left and right side of the triangles are means that those 2 lines are equal and thus forming a isosceles triangle.

This means that the bottom right angle is also 2x+2 degrees.

Now because all 3 angles in a triangle adds to 180 degrees, we can set up equation.

3x+1+2x+2+2x+2=180

Now combine like terms

7x+5=180

Then solve, first subtract 5 from both sides.

7x=175

Now divide 7 from both sides

x=25
