If ∆ABC = ∆EDF where the coordinates of A(0,2), B(2,4), and C(2,-1), what is the measure of DF?A-3B-3.1C-5D-5.9Please respond qu

aev [14]

The triangles ABC and EDF are congruent, meaning they have the same side lengths and angles measures.

The measure of DF, as both triangles are congruent, is equal to the measure of BC.

We can calculate the length of BC using the distance formula:

$\begin{gathered} D=\sqrt[]{(x_c-x_b)^2+(y_c-y_b_{})^2} \\ D=\sqrt[]{(2-2)^2+(-1-4)^2} \\ D=\sqrt[]{0^2+(-5)^2} \\ D=\sqrt[]{(-5)^2} \\ D=|-5| \\ D=5 \end{gathered}$

As BC is congruent with DF and BC=5, the length of DF is 5 units.

Suppose the population of a certain city is 5831 thousand. It is expected to decrease to 5204 thousand in 50 years. Find the per

SVEN [57.7K]

Answer:

The percent decrease is approximately $10.75\%$

(Don't know what you are expected to round to.)

Step-by-step explanation:

Percent change can be calculated by doing:

$\frac{\text{original}-\text{new}}{\text{original}}$

Then you multiply the result to covert it to a percentage.

Let's use this formula:

$\frac{5831 \text{thousand}-5204 \text{ thousand }}{5831 \text{thousand}}$

$\frac{\text{thousand}}{\text{thousand}} \cdot \frac{5831-5204}{5831}$

$\frac{5831-5204}{5831}$

$\frac{627}{5831}$

$0.1075$ approximately

Now the answer as a percent is $10.75\%$ approximately.

The percent decrease is approximately $10.75\%$
