How is optimization employed in mathematics?

The process of selecting the optimal answer from a range of alternatives is known as optimization. In mathematics, optimization is employed to determine a function's maximum or least value. Typically, an optimization issue entails the optimization of a function under a set of restrictions.

Let's assume that the length of the left border is x feet.

The length of the lower border is y feet.

From the given situation the equation is:

8x + 2y = 320

To maximize the area of the garden, we maximize the product xy.

2y = 320 - 8x

y = 160 - 4x

Substituting this expression for y into the expression for the area, we get:

A = xy = x(160 - 4x) = 160x - 4x²

To find the value of x that maximizes the area, we can take the derivative of A with respect to x and set it equal to zero:

dA/dx = 160 - 8x = 0

x = 20

Substituting x = 20 back into the expression for y, we get:

y = 160 - 4x = 80

Therefore, the dimensions of the garden are 20 feet by 80 feet, and the area enclosed is: A = xy = (20)(80) = 1600 feet².

In the equation, the ordered pair for x = 5 is (5, 5.5), the ordered pair for x = 10 is (10, 8), the ordered pair for x = 20 is (20, 13).

A linear equation has the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. The line's rate of change, or how steeply it rises or descends as we go down the x-axis, is indicated by the slope. The line's intersection with the y-axis, or the value of y when x is equal to 0, is represented by the y-intercept.

The given equation is:

y=0.50x + 3

Substituting the different values of x we find the required ordered pair as follows:

When x = 5:

y = 0.50(5) + 3 = 5/2 + 6/2 = 11/2 = 5.5

When x = 10:

y = 0.50(10) + 3 = 5 + 3 = 8

When x = 20:

y = 0.50(20) + 3 = 10 + 3 = 13

Therefore, the ordered pair for x = 5 is (5, 5.5), the ordered pair for x = 10 is (10, 8), the ordered pair for x = 20 is (20, 13).

Answer:

The center of the circle is at the point (2, -3), and its radius is 4 units

Step-by-step explanation:

The equation of the circle in standard form can be obtained by completing the square for both x and y terms as follows:

7x^2 - 28x + 7y^2 + 42y - 35 = 0

7(x^2 - 4x) + 7(y^2 + 6y) = 35

7(x^2 - 4x + 4 - 4) + 7(y^2 + 6y + 9 - 9) = 35

7[(x - 2)^2 - 4] + 7[(y + 3)^2 - 9] = 35

7(x - 2)^2 + 7(y + 3)^2 - 112 = 0

7(x - 2)^2 + 7(y + 3)^2 = 112

Dividing by 112 on both sides, we get:

(x - 2)^2 + (y + 3)^2 / 16 = 1

Therefore, the equation of the circle in standard form is (x - 2)^2 + (y + 3)^2 / 16 = 1.

The center of the circle is at the point (2, -3), and its radius is 4 units.

The solution of the linear equation y =  15 x + 9 and y = 1/2 x - 20 is

x = -2

y = -21

The linear equation can be solved by graphical method to give the solution. The graph is attached

(-2, 21)

Using elimination method we have

y =  15 x + 9

y = 1/2 x - 20

Answer:

Let's start by finding how much money Mary has left after buying the gift cards:

$250 - $130 = $120

Now, to find the greatest number of candy bars Mary can buy, we need to divide the amount of money she has left by the cost of each candy bar:

$120 ÷ $1.50 = 80

So Mary can buy up to 80 candy bars with the rest of her money.

We can check which inequality represents this situation by plugging in the numbers:

130 + 1.50x ≤ 250

where x represents the number of candy bars Mary buys.

If we subtract 130 from both sides, we get:

1.50x ≤ 120

Finally, if we divide both sides by 1.50, we get:

x ≤ 80

This matches our answer, so the correct inequality is:

D. 130 +1.50x ≤ 250

Answer:

D. 130 +1.50x ≤ 250

Step-by-step explanation:

250 - 130 = 120

The surface area of the cylinder is 39 1/4

Cylinder is  is a three-dimensional solid consisting of two parallel circular bases joined together by a curved surface at a particular distance from the center of the circular bases. Cylinder has two flat ends in the shape of circles.

How to determine the surface area of cylinder

Surface area of cylinder is is the total space occupied by the flat circular bases of the cylinder and the curved surface.

Surface area = 2πrh + 2πr^2

Surface area = 2πr(r + h)

Where π = 22/7

r = 1 1/4 = 5/4

h = 3 3/4 = 15/4

SA = 2 * 22/7 * 5/4(5/4 + 15/4)

SA = 44/7 * 5/4(5)

SA = 44/7 * 6.25

SA = 39.2857 cm^2

Surface Area = 39 1/4 cm^2 is also related to 39.2857 cm^2

Therefore, the exact surface area of cylinder is 39 1/4 cm^2

The highest height of the ball, to the closest foot, is stated to be around 88 feet.

Velocity may be referred to as the speed when something moves toward a particular location. as the rate of a car driving northwest on a highway or the pace at which a rocket takes off.

The function h(t) = −16t² + v0t + h0 models the vertical motion of the ball, where t is time in seconds, v0 is the initial velocity in feet per second, and h0 is the initial height in feet.

In this case, the beginning height is 4 feet, and the velocity of the fluid equals 75 feet per second. As a result, the following outlines the function h(t) which it simulates the ball's vertical motion:

h(t) = -16t² + 75t + 4

The point of the concave function h must be located in order to determine the ball's peak (t) = -16t² + 75t + 4.

The t-coordinate of the vertex is given by t = -b/2a, where a = -16 and b = 75. Substituting these values, we get:

t = -75 / (2 x (-16)) = 2.34375

We enter this t quantity into the procedure h(t) to get the maximum height:

h(2.34375) = -16(2.34375)² + 75(2.34375) + 4 = 87.74

To the nearest foot, the ball therefore achieves a peak of 88 feet.

Since it doesn't make sense for Timothy to have negative money, we can conclude that there is no solution to this problem.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's assume that Timothy has x dollars when he enters the first store.

According to the problem, he spends 1 dollar more than half of what he has.

So, the amount he spends in the first store is:

1/2 * x + 1

After spending this amount, he will have:

x - (1/2 * x + 1) = 1/2 * x - 1

dollars left.

He then goes to the second store and spends 1 dollar more than half of what he has left, which is:

1/2 * (1/2 * x - 1) + 1 = 1/4 * x + 1/2

After spending this amount, he will have:

1/2 * x - 1 - (1/4 * x + 1/2) = 1/4 * x - 3/2

dollars left.

He repeats this process for each of the five stores.

Therefore, the amount of money Timothy has left after visiting all five stores is:

1/4 * x - 3/2 - (1/4 * x + 1/2) - (1/4 * x + 1/2) - (1/4 * x + 1/2) - (1/4 * x + 1/2) = -5/4 * x - 5

Since he has spent all his money, the amount of money he has left must be 0:

-5/4 * x - 5 = 0

Solving for x, we get:

x = -20

A triangle is a two-dimensional geometric shape with three straight edges and three angles. It is one of the fundamental geometric forms and can be categorised in various ways based on the sides and angles it has. Triangles are typically categorised according to their edges as follows: Equilateral triangles have three identical sides and three equal angles, each measuring 60 degrees. A triangle with an isosceles triangle has two edges that are equal and two angles that are equal.

A triangle called a scalene triangle lacks equal edges and angles.

To find the equation of the perpendicular bisector of PQ, we need to first find the midpoint of PQ, and then determine the slope of the line perpendicular to PQ that passes through this midpoint.

The midpoint of PQ is given by the formula:

((x1 + x2) / 2, (y1 + y2) / 2)

where (x1, y1) = (5, -4) and (x2, y2) = (-1, -2)

So, the midpoint of PQ is:

((5 - 1) / 2, (-4 - 2) / 2) = (2, -3)

Now, the slope of the line PQ can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (5, -4) and (x2, y2) = (-1, -2)

So, the slope of PQ is:

(-2 - (-4)) / (-1 - 5) = 2/3

Since the perpendicular bisector of PQ will have a slope that is the negative reciprocal of the slope of PQ, the slope of the perpendicular bisector is:

-1 / (2/3) = -3/2

Finally, we can use the point-slope form of the equation of a line to find the equation of the perpendicular bisector. We know that the line passes through the point (2, -3), and has a slope of -3/2. So, the equation of the line is:

y - (-3) = (-3/2)(x - 2)

Simplifying this equation, we get:

y + 3 = (-3/2)x + 3

y = (-3/2)x + 0

Hence, the equation of the perpendicular bisector of PQ is y = (-3/2)x.

737 cooks are required to prepare a meal for 737 people in 5 hours

Step-by-step explanation:

According to the given information, 10 cooks can prepare a meal for 536 people working for 8 hours each.

Let's calculate the total work done by the 10 cooks in 8 hours.

Total work done = Number of cooks * Hours worked

Total work done = 10 * 8 = 80

Now, let's calculate the work done by one cook in one hour.

Work done by one cook in one hour = Total work done / (Number of cooks * Hours worked)

Work done by one cook in one hour = 80 / (10 * 8) = 1

Therefore, one cook can prepare food for 1 person in 1 hour.

Now, let's calculate the number of cooks required to prepare a meal for 737 people in 5 hours.

Total work required = Number of people * Hours required

Total work required = 737 * 5 = 3685

Number of cooks required = Total work required / (Hours worked * Work done by one cook)

Number of cooks required = 3685 / (5 * 1) = 737

Therefore, 737 cooks are required to prepare a meal for 737 people in 5 hours.
