Answer:
Perimeter is 56
Step-by-step explanation:
Notice that Given that is an ellipse, consider a conversion to polar coordinates:
The Jacobian for this transformation is
with determinant
Then the integral in polar coordinates is
where you can evaluate the remaining integral by substituting and .
To evaluate the integral, we make a change of variables using the transformation x=u/8 and y=v/9 to transform the region into a unit circle. Then we convert the integral to polar coordinates and evaluate it.
To evaluate the given integral, we can make the appropriate change of variables by using the transformation x = u/8 and y = v/9. This will transform the region R into a unit circle. The determinant of the Jacobian of the transformation is 1/72, which we will use to change the differential area element from dA to du dv. Substituting the new variables and limits of integration, the integral becomes:
L = \iint_{R} 9 \sin (612 u^{2} + 768 v^{2}) \cdot (1/72) \,du \,dv
Next, we can convert the integral from Cartesian coordinates(u, v) to polar coordinates (r, \theta). The integral can be rewritten as:
L = \int_{0}^{2\pi} \int_{0}^{1} 9 \sin (612 r^{2} \cos^{2}(\theta) + 768 r^{2} \sin^{2}(\theta)) \cdot (1/72) \cdot r \,dr \,d\theta
We can then evaluate this integral to find the value of L.

Given that:
Length of a rope = 224 cm
Rope is cut so that one part is 3/4 of the other.
Solution:
Let one part of a rope be x cm.
So other part of the rope is .
Total length
Now,
Multiply both sides by 4.
Divide both sides by 7.
The value of one part 128 cm.
Second part
Therefore, the length of shorter rope is 96 cm and the length of longer rope is 128 cm.
Answer:
I think 1 is the right answer
Step-by-step explanation:
Answer:
108 units
Step-by-step explanation:
We are given that
Length of each office,l=10 units
Breadth of each office=b=8 units
Total number of office=3
We know that
Perimeter of rectangle=
Using the formula
Length of cable for 1 office=
Length of cable required for 3 offices=units
Hence, the required length of cable=108 units
How do I solve 7,9, and 10 also what are the answers?
Answer:
see below
Step-by-step explanation:
The cube of something to the 1/3 power is the original something. The cube of a cube root of something is the original something. Since the cube of a cube root is the same as the cube of a 1/3 power, the 1/3 power is equivalent to the cube root.
The applicable rules of exponents are ...
(a^b)^c = a^(bc)
