If the points (-8, 7) and T (6,-3) are on a line segment, find the length of ST.

larisa86 [58]

Answer:

The answer is

<h2>2√74 or 17.20 units</h2>

Step-by-step explanation:

The length of w line segment between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

S(-8, 7) and T (6,-3)

The length of ST is

$|ST| = \sqrt{ ({ - 8 - 6})^{2} + ({7 + 3})^{2} } \\ = \sqrt{ ({ - 14})^{2} + {10}^{2} } \\ = \sqrt{196 + 10} \\ = \sqrt{296} \\ = 2 \sqrt{74} \\ = 17.2046505...$

We have the final answer as

<h3>2√74 or 17.20 units</h3>

Hope this helps you

URGENT HELP<br> Pqr is an isosceles triangle and prs is a straight line

katrin2010 [14]

Answer:

∠ QRS = 132°

Step-by-step explanation:

Since the triangle is isosceles then the 2 base angles are congruent, that is

∠ PQR = ∠ PRQ = $\frac{180-84}{2}$ = $\frac{96}{2}$ = 48°

∠ PRQ and ∠ QRS are adjacent angles , so

∠ QRS = 180° - 48° = 132°

A classroom has two rows of 8 seats each. there are 14 students, 5 of whom always sit in the front row and 4 of whom always sit

Kaylis [27]

Answer:

28,449,792,000

Step-by-step explanation:

There are 8P5 = 6720 ways the five students who sit on the front row can arrange themselves.

There are 8P4 = 1680 ways the four students who sit on the back row can arrange themselves.

In the remaining 7 seats, there are 7P5 = 2520 ways the remaining 5 students can arrange themselves.

The total number of possible arrangements of students (with the given limitations) is ...

6720·1680·2520 = 28,449,792,000

_____

nPk = n!/(n-k)!

so 8P5 = 8!/3! = 8·7·6·5·4 = 6720
