Find the distance from (7, 4) and (-1,-4)<br> A. 11.31<br> B. 8<br> C. 10.42<br> D. 9.76

Neko [114]

Answer:

Step-by-step explanation:

Calculate the distance using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (7, 4 ) and (x₂, y₂ ) = (- 1, - 4 )

d = $\sqrt{(-4-4)^2+(-1-7)^2}$

= $\sqrt{(-8)^2+(-8)^2}$

= $\sqrt{64+64}$

= $\sqrt{128}$

≈ 11.31 ( to 2 dec. places )

Give Triangle QRS ~= Triangle TUV, QS = 3v + 2 and TV = 7v - 6, find the length of QS and TV

stealth61 [152]

$QS\cong TV=8$

1) Since these triangles are congruent, then we can write out the following for congruent triangles have congruent sides:

$\begin{gathered} QS=TV \\ 3v+2=7v-6 \\ 3v-7v=-6-2 \\ -4v=-8 \\ 4v=8 \\ \frac{4v}{4}=\frac{8}{4} \\ v=2 \end{gathered}$

2) Still based on that principle, we can plug v=2 into any of those formulas to get the measure of QS and TV. So let's pick the simpler one:

$\begin{gathered} QS=3v+2 \\ QS=3(2)+2 \\ QS=6+2 \\ QS=8 \\ --- \\ TV=7(2)-6 \\ TV=14-6 \\ TV=8 \end{gathered}$

As we can see these segments are congruent.
