The quantity n varies jointly with the product of z and the square of the sum of x and y. When n is 18, x = 2, y = 1, and z = 3. What is the constant of variation?

Answers

Answer:

Constant of variation is, $(2)/(3)$

Step-by-step explanation:

Joint Variation states that it is jointly proportional to a set of variables i.e, it means that z is directly proportional to each variable taken one at a time.

Given the statement: The quantity n varies jointly with the product of z and the square of the sum of x and y.

"The square of sum of x and y" means $(x+y)^2$

"Product of z and the square of the sum of x and z" means $z * (x+y)^2$

then; by definition we have;

$n \propto z * (x+y)^2$

our equation will be of the form of:

$n = k \cdot z(x+y)^2$ ......[1] ; where k is constant of Variation.

Given: n =18 , x =2 , y= 1 and z = 3

Solve for k;

Substitute these given values in [1] we have;

$18= k \cdot 3(2+1)^2$

Simplify:

$18= k \cdot 27$

Divide both sides by 27 we get;

$k = (18)/(27) = (2)/(3)$

therefore, the constant of variation is, $(2)/(3)$

Hello,

n=k*z*(x+y)²
with n=18,x=2,y=1 and z=3
==>18=k*3*(2+1)²
==>k=18/27=2/3

The area of the triangle is 48cm. Then find the length of corresponding altitudes

Answers

Area of triangle = 1/2 × base × height
Base of the triangle = (2 Area)/height
Height of the triangle = (2 Area)/base

Given:
A = 48 cm^2
Base of the triangle = (2 x 48 )/height
Height of the triangle = (2 x 48)/base
Let the triangle be isosceles :
So,
base = height

Therefore,
Base of the triangle = (2 x 48 )/Base
(Base)^2 = 96
Base = √96
Base = √(2*2*2*2*6)
Base = 4√6
height = 4√6

how do you explain the midpoint of cd is e (-1,0). one endpoint is c(5,2). what are the coordinates of the other endpoint?

Answers

The other endpoint will be equal to (-7, -2).

What is coordinate geometry?

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the midpoint of cd is e ( -1,0 ) one endpoint is c( 5,2 ). The midpoint will be calculated as:-

Midpoint = (x₁+x₂ / 2 , y₁+y₂ / 2)

5 + x₂ / 2 = -1

5 + x₂ = -2

x2 = -7

2 + y₂ / 2 = 0

2 + y₂ = 0

y₂ = -2

Therefore, the other endpoint will be equal to (-7, -2).
