Answer: The value of 'n' is 6.

Step-by-step explanation:  Given that ΔXWZ is an isosceles triangle, where XZ = n, WZ = 2n - 5, and the perimeter of the triangle is 20 units.

We are to find the value of 'n'.

As given in the figure, in ΔXWZ,

WX = WZ.

So, WX = 2n - 5.

We know that the perimeter of a triangle is equal to the sum of its three sides, so the perimeter of ΔXWZ is given by

P=XZ+WX+WZ=n+(2n-5)+(2n-5)=5n-10.

According to the question, we have

P=20\\\\\Rightarrow 5n-10=20\\\\\Rightarrow 5n=30\\\\\Rightarrow n = 6.

Thus, the value of 'n' is 6.

for what value of k, the line joining 3x-ky+7=0 is perpendicular to the line joining (4 ,3) and ( 5, -3).
Schach [20]

Answer:

  • k = 18

=========

<h2>Given</h2>

<h3>Line 1</h3>
  • 3x - ky + 7 = 0

<h3>Line 2</h3>
  • Passing through the points (4, 3) and (5, - 3)

<h2>To find</h2>

  • The value of k, if the lines are perpendicular

<h2>Solution</h2>

We know the perpendicular lines have opposite reciprocal slopes, that is the product of their slopes is - 1.

Find the slope of line 1 by converting the equation into slope-intercept from standard form:

<u><em>Info:</em></u>

  • <em>standard form is ⇒ ax + by + c = 0, </em>
  • <em>slope - intercept form is ⇒ y = mx + b, where m is the slope</em>

  • 3x - ky + 7 = 0
  • ky = 3x + 7
  • y = (3/k)x + 7/k

Its slope is 3/k.

Find the slope of line 2, using the slope formula:

  • m = (y₂ - y₁)/(x₂ - x₁) = (-3 - 3)/(5 - 4) = - 6/1 = - 6

We have both the slopes now. Find their product:

  • (3/k)*(- 6) = - 1
  • - 18/k = - 1
  • k = 18

So when k is 18, the lines are perpendicular.

a diver begins a sea level and dives down 200 feet. he ascends at a steady rate of 12 and 1 thirds feet per minute for 4.5 minut
Komok [63]

12 1/3 x 4.5 = 55 1/2 feet

-200 + 55 1/2 = -144 1/2

 the diver is at  -144 1/2 feet
