4.63 clark's country pet resort is fencing a new play area for dogs. the manager has purchased 130 yd of fence to enclose a rectangular pen. the area of the pen must be 1050 ydsquared. what are the dimensions of the pen?
The problem involves determining the dimensions of a rectangular pen using given fencing length and area. Two possible solutions were found: the dimensions of the pen could be 30 yards by 35 yards, or 100 yards by 15 yards.
The manager at Clark's Country Pet Resort is trying to construct a rectangular pen for dogs with a fixed amount of fencing and a desired area.
Given that the length of the fencing is 130 yards and the area must be 1050 square yards, we can solve this problem by applying algebra and the principles of rectangle properties.
Consider 'l' to be the length of the rectangle and 'w' to be the width of the rectangle. We know that the perimeter of a rectangle is 2l + 2w. Given the total length of fencing available is 130 yards, it can be formulated as 2l + 2w = 130.
The area of a rectangle is given by l*w. As we know the area is 1050 square yards, it can be written as l*w = 1050.
We now have a pair of equations which we can solve simultaneously to find the values of 'l' and 'w'.
From the first equation, we can express 'w' as (130 - 2l) / 2. Putting this into the area equation gives us l * (130 - 2l) / 2 = 1050. Solving for 'l' we get two possible solutions: l = 30 yd or l = 100 yd. By substituting these values back into the first equation, we get the corresponding values of 'w' which are 35 yd and 15 yd respectively.
Thus, the dimensions of the pen could be either 30 yd by 35 yd or 100 yd by 15 yd.

c.

b.
expanded horizontally by a factor of 3, horizontal shift left 6, vertical shift up 3
d.
compressed vertically by a factor of 1/3, horizontal shift right 2, vertical shift up 3
Answer:
C. Compressed horizontally by a factor of 1/3, horizontal shift right 2, vertical shift up 3
Step-by-step explanation:
If a function f(x) is transformed and make f(kx),
f(x) is compressed horizontally by the factor 1/k if k > 1
f(x) is stretched horizontally by the factor 1/k if 0 < k < 1
Also, if f(x) is transformed and make f(x+a),
f(x) is shifted right if a < 0
f(x) is shifted left if a > 0,
Now, if f(x) gives f(x) + k after transformation,
f(x) is shifted vertically k unit up if k > 0,
f(x) is shifted vertically k unit down if k < 0,
Here, the parent function,
[tex]f(x) = x^2[/tex]
transformed function,
[tex]g(x)=(3x-6)^2+3=(3(x-2))^2+3[/tex]
Thus, by the above explanation,
f(x) is compressed horizontally by a factor of 1/3, horizontal shift right 2, vertical shift up 3.

In a class of 40, 28 passed their maths test. What fraction of the class passed?
Out of a class of 40 students, 28 passed their maths test. The fraction of the class that passed the test is 28/40, which simplifies to 7/10.
Explanation:The class consists of 40 students. The problem mentions that 28 of these students passed their maths test. To find the fraction of the class that passed, we have to compare the number of students who passed with the total number of students in the class. This is done by dividing the number of students who passed the test by the total class size. So, the fraction of the students who passed is 28/40. However, this fraction can be simplified by dividing both the numerator (28) and the denominator (40) by their greatest common divisor, which is 4. The result is 7/10. Therefore, the fraction of the class that passed the maths test is 7/10.

Cody is twice as old as Evan and seven years ago the sum of their age was 7. find the age of each boy now
Cody is currently 14 years old and Evan is 7 years old, as determined by setting up an equation based on the information provided and solving for their ages.
Let's set up an equation to solve this problem by letting the current age of Evan be x. Since Cody is twice as old as Evan, Cody's current age would be
2x. We are told that seven years ago, their ages added up to 7. Therefore, we can express this as (x - 7) + (2x - 7) = 7. Simplifying this equation gives us 3x - 14 = 7. Adding 14 to both sides gives us 3x = 21. Dividing both sides by 3 gives us x = 7, which is Evan's current age. Therefore, Cody's age is 2x which is 2*7 = 14. Cody is 14 years old and Evan is 7 years old now.

Let f = (ax + by + 4z) i + (x + cz) j + (9y + mx) k where a, b,c, and m are constants.
a.suppose that the flux of f through any closed surface is 0. which of the constants can be determined?
If the flux of a vector field through a closed surface is zero, this implies that the divergence of the field is zero everywhere. This condition can be used to determine some constants of the vector. In the provided equation, we can determine one of the constants a, c or m if we know the other two.
Explanation:The subject matter of this question is within vector calculus, a field of mathematics used in physics and engineering. The question talks about the flux of a vector field f through a closed surface which is given to be zero.
When the flux through any closed surface is zero, it implies that the divergence of the vector field f is zero everywhere. This condition allows us to determine some of the coefficients of the components of f. In this case, we have: f = (ax + by + 4z) i + (x + cz) j + (9y + mx) k
The operation that gives the divergence of a vector field in three-dimensional Cartesian coordinates is given by the dot product of the del operator with the vector field. This means:
div f = ∂/∂x(ax+by+4z) + ∂/∂y(x+cz) + ∂/∂z(9y+mx) = a + c + m
For the flux of f through the surface to be zero, the divergence of f needs to equal zero, that is a + c + m =0. Therefore, for a given set of a, c, and m, we can determine one of them knowing the others.
