Given that the garden should be in a circular shape.
And the circumference of the circle would be, C = 132 feet.
It says to find the radius of the circular garden, r = ?
We know the formula for Circumference of the circle is given as follows :-
Circumference of circle = 2π x radius
C = 2·π·r
Hint:- It says to use pi = 22/7.
[tex] 132=2*\frac{22}{7}*r \\\\
132=\frac{44}{7}*r \\\\
r=132*\frac{7}{44} \\\\
r= \frac{924}{44} \\\\
r= 21 \;feet [/tex]
Hence, Radius would be r = 21 feet.

Solve the inequalities by graphing. Select the correct graph. y > x y < -x
The solution to the system of inequalities y > x and y < -x is a V-shaped region in the second and fourth quadrants of the coordinate plane.
Graph attached.
To solve the system of inequalities graphically, you need to shade the regions on the coordinate plane that satisfy both inequalities.
The first inequality is y > x. This means that all points above the line y = x satisfy this inequality.
The second inequality is y < -x. This means that all points below the line y = -x satisfy this inequality.
Now, let's graph both lines and shade the regions that satisfy both inequalities:
Graph the line y = x. This is a straight line with a slope of 1 that passes through the origin (0,0) and goes up and to the right.
Graph the line y = -x. This is also a straight line with a slope of -1 that passes through the origin (0,0) and goes down and to the right.
Graph attached.
The shaded region that satisfies both inequalities is the area between these two lines, below y = -x, and above y = x.
It forms a V-shaped region in the second and fourth quadrants of the coordinate plane.
Therefore, the correct graph should show the shaded V-shaped region that represents the solution to the system of inequalities.

Suppose you are climbing a hill whose shape is given by the equation z = 1400 − 0.005x2 − 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (100, 120, 1206). the positive x-axis points east and the positive y-axis points north. (a) if you walk due south, will you start to ascend or descend?
If walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.
To determine whether you will ascend or descend when walking due south from the point (100, 120, 1206), we need to consider the slope of the hill in the southward direction, which corresponds to the negative y-direction.
Given the equation of the hill's shape: [tex]\[ z = 1400 - 0.005x^2 - 0.01y^2 \][/tex]
We can find the slope in the y-direction (southward) by taking the partial derivative of z with respect to y:
[tex]\[ \frac{\partial z}{\partial y} = -2 \cdot 0.01 \cdot y \][/tex]
Evaluating this derivative at the point (100, 120, 1206) gives us the slope in the y-direction at that point:
[tex]\[ \frac{\partial z}{\partial y}\Bigg|_{(100, 120, 1206)} = -2 \cdot 0.01 \cdot 120 = -2.4 \][/tex]
Since the slope is negative, this means that as you move in the positive y-direction (northward), the height z decreases. Conversely, moving in the negative y-direction (southward) will also result in a decrease in height z, because the slope is linear and does not change direction.
Therefore, walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.

At a store, 3 chairs and 4 desks together cost $367.95. The total costof 4 chairs and 6 beds is $$720.72. If the price of the desk is 2 times as much as the price of the chair, what is the total cost of 5 desks and 4 beds?
After creating equations based on the given costs and solving for the price of chairs, desks, and beds, we find that the total cost for 5 desks and 4 beds is $725.78.
Explanation:To solve this problem, we will start by setting up two equations based on the information given about the prices of chairs, desks, and beds. Let's denote the cost of one chair as C, the cost of one desk as D, and the cost of one bed as B. According to the problem, the desk costs 2 times as much as the chair, so we have D = 2C.
Now, we can create equations based on the total costs provided:
3 chairs and 4 desks cost $367.95 -> 3C + 4D = 367.954 chairs and 6 beds cost $720.72 -> 4C + 6B = 720.72Substitute the value of D from D = 2C into the first equation:
3C + 4(2C) = 367.95 -> 11C = 367.95 -> C = 33.45
With the cost of a chair found, we can find the cost of a desk:
D = 2C = 2(33.45) = 66.90
Now, to find the cost of a bed, we use the second equation and substitute values for C:
4C + 6B = 720.72 -> 4(33.45) + 6B = 720.72 -> 133.80 + 6B = 720.72 -> 6B = 586.92 -> B = 97.82
Finally, we calculate the total cost of 5 desks and 4 beds:
5D + 4B = 5(66.90) + 4(97.82) = 334.50 + 391.28 = 725.78
The total cost of 5 desks and 4 beds is $725.78.

Find the distance from the point to the given plane. (1, −7, 8), 3x + 2y + 6z = 5
To find the distance from the point (1, -7, 8) to the plane 3x + 2y + 6z = 5, we use the formula for the distance of a point from a plane, resulting in a distance of 32/7 units.
Explanation:The question deals with finding the distance from a point to a given plane. Specifically, it asks for the distance from the point (1, −7, 8) to the plane defined by the equation 3x + 2y + 6z = 5. To solve this, we use the formula for the distance of a point (x1, y1, z1) from a plane ax + by + cz = d:
D = |ax1 + by1 + cz1 − d| / √(a2 + b2 + c2)
Substituting the given values, we get:
D = |3(1) + 2(−7) + 6(8) − 5| / √(32 + 22 + 62)
This simplifies to:
D = |3 − 14 + 48 − 5| / √(9 + 4 + 36)
D = |32| / √49
D = 32 / 7
Therefore, the perpendicular distance from the point to the plane is 32/7 units.

Last year the chess club had 20 members. This year the club has 15 members. Find the percentage of change and state whether the percent of change is an increase or decrease
The negative sign indicates a decrease in the number of members. Therefore, the percentage change of -25% means that the number of members decreased by 25%. To summarize, the percentage change in the number of members from last year to this year is 25% decrease.
To find the percentage change in the number of members from last year to this year, we'll use the formula for percentage change:
[tex]\[ \text{Percentage change} = \left( \frac{\text{New value} - \text{Old value}}{\text{Old value}} \right) \times 100\% \][/tex]
Given that last year the chess club had 20 members and this year it has 15 members, we can plug these values into the formula:
[tex]\[ \text{Percentage change} = \left( \frac{15 - 20}{20} \right) \times 100\% \][/tex]
[tex]\[ \text{Percentage change} = \left( \frac{-5}{20} \right) \times 100\% \][/tex]
[tex]\[ \text{Percentage change} = -\frac{1}{4} \times 100\% \][/tex]
[tex]\[ \text{Percentage change} = -25\% \][/tex]
The negative sign indicates a decrease in the number of members. Therefore, the percentage change of -25% means that the number of members decreased by 25%.
To summarize, the percentage change in the number of members from last year to this year is 25% decrease.
The complete question is:
Last year the chess club had 20 members. This year the club has 15 members. Find the percentage of change and state whether the percent of change is an increase or decrease.

Find the equations of the tangent line to the curve at the given point. y = 9cos x. (π/3,4.5)
The equation of the tangent line to the curve is
y = -9 ( √3 / 2 )x + [ ( 3π√3 + 9 ) / 2 ]
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the curve be y = 9 cos ( x )
To find the equation of the tangent line to the curve y , take the derivative of y , we get
dy / dx = 9 ( - sin ( x ) )
dy / dx = -9 sin ( x )
So , y' = -9 sin ( x )
when x = π/3
Now plug in your value for x into y'
-9 sin ( π/3 ) = -9 ( √3 / 2 )
This is the slope of the tangent line at x = π/3
And , To find the equation of the tangent line, we need a value for y. Simply plug your x value into the original equation for y
So ,
y = 9 cos x
y = 9 cos ( π / 3 )
y = 9 ( 1/2 )
y = 9/2
Now use point slope form to find the equation of the tangent line
y - y₁ = m ( x - x₁ )
Substituting the values in the equations , we get
y - 9/2 = -9 ( √3 / 2 ) ( x - π/3 )
On simplifying the equation , we get
y - 9/2 = -9 ( √3 / 2 )x + 9 ( √3 / 2 ) ( π/3 )
Adding 9/2 on both sides of the equation , we get
y = -9 ( √3 / 2 )x + [ ( 3π√3 + 9 ) / 2 ]
Hence , the equation is y = -9 ( √3 / 2 )x + [ ( 3π√3 + 9 ) / 2 ]

select the correct product (x2+3)(x3-5)
The question involves multiplying two polynomials, (x^2+3) and (x^3-5), using the distributive property to find the product x^5 - 5x^2 + 3x^3 - 15.
The question asks for the product of the polynomials (x2+3) and (x3-5). To find the product, each term in the first polynomial is multiplied by each term in the second polynomial. This is known as the distributive property or the FOIL method when dealing with binomials. Therefore, the product is:
x^5 - 5x^2 + 3x^3 - 15.
To summarize the multiplication process:
Multiply x2 by x3 to get x5
Multiply x2 by -5 to get -5x2
Multiply 3 by x3 to get 3x3
Multiply 3 by -5 to get -15
Hence, This is the standard process for multiplying polynomials.
