<h2>√512 by √512 </h2>
Step-by-step explanation:
Length the length and breadth of the rectangle be x and y.
Area of the rectangle A = Length * breadth
Perimeter P = 2(Length + Breadth)
A = xy and P = 2(x+y)
If the area of the rectangle is 512m², then 512 = xy
x = 512/y
Substituting x = 512/y into the formula for calculating the perimeter;
P = 2(512/y + y)
P = 1024/y + 2y
To get the value of y, we will set dP/dy to zero and solve.
dP/dy = -1024y⁻² + 2
-1024y⁻² + 2 = 0
-1024y⁻² = -2
512y⁻² = 1
y⁻² = 1/512
1/y² = 1/512
y² = 512
y = √512 m
On testing for minimum, we must know that the perimeter is at the minimum when y = √512
From xy = 512
x(√512) = 512
x = 512/√512
On rationalizing, x = 512/√512 * √512 /√512
x = 512√512 /512
x = √512 m
Hence, the dimensions of a rectangle is √512 m by √512 m

Answer:
Option 2) y = 26
Step-by-step explanation:
We are given the following in the question:
The individual wants to have two hot dogs for each guest, and 6 extra hot logs in case some teammates bring friends.
Thus, the dependent variable is the number of hot dogs.

The independent variable is the number of teammates.

Thus, the linear relation between the dependent and the independent variable is given as:

We have to find the value of dependent variable when independent variable is 10
For x = 10

Thus, the correct answer is
Option 2) y = 26
Answer:
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo,
<em>A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2.
</em>
<em>What is the volume of the pyramid?</em>
My answer:
As we know, The volume of a pyramid =
base area × its height
Given:
- Side lenght of the base is;

=> The area of the base is
- In Δ ACB measure of angle ACB is 90° and m∠ CAB is 30°
We use:
<=> BC = 
= 4 cm
And BC is the height of the the pyramid
=> The volume of a pyramid =
* 4 cm
=
