Let's rewrite the mixed number as a fractions:

$\begin{gathered} 3\frac{2}{3}=\frac{11}{3} \\ 4\frac{1}{2}=\frac{9}{2} \end{gathered}$

Therefore, the total length will be:

$3\cdot(\frac{11}{3})+2(\frac{9}{2})+4=24ft$

Why do some quadratic graphs move left or right and others do not? Is there a correlation between this and them moving up and do

Vikentia [17]

Answer:

(x + 3)^2 is left 3 because it becames 0 at -3

(x - 3)^2 is right 3 because it becames 0 at 3

x^2 +3 is up 3 because your just adding 3 units up

x^2 - 3 is down 3 because your just subtracting 3 units down

Nady [450]

Answer:

-1.2

Step-by-step explanation:

Given that the designer also programs a bird with a path that can be modeled by a quadratic function.

The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).

If we treat this curve as line joining these two points then we can find the slope by the formula

Slope = change in y coordinate/change in x coordinate

Here the points given are

(0,20) and (10,8)

$Change in y coordinate = 8-20 = -12\\Change in x coordinate = 10-0 = 10\\Slope = -1.2$

Slope of the line that represents the turtle's path

=-1.2

FinnZ [79.3K]

Answer:

your answer is correct.

Step-by-step explanation:

For the purpose here, we'll call the missing point on the arc through Z point X.

Essentially, you want to make ΔXYZ ≅ ΔLMN by SSS. The construction so far ensures LM ≅ MN ≅ XY ≅ YZ. By copying the length LN to XZ, you ensure the congruence of the remaining sides of the triangles.

Then ∠XYZ ≅ ∠LMN because corresponding parts of congruent triangles are congruent.

In short, XZ needs to be the same distance as LN.
