Answer:

The square's area will be larger

Step-by-step explanation:

Let's say that a square's side length is 10.

To find the perimeter of a square, we add up all of the sides.

10 + 10 + 10 + 10 = 40

The perimeter of the square would be 40.

Now let's figure out the area of this square.

To find the area, we multiply the length by the width.

10 × 10 = 100

The area of the square is 100.

Now let's move on to the rectangle.

The rectangle has a side length of 12, and 8.

Let's figure out the perimeter of this rectangle.

12 + 12 + 8 + 8 = 40

The perimeter of the rectangle is 40, which means that the perimeters are the same.

Now let's figure out the area.

If you remember, to find the area we multiply the side length by the width.

12 × 8 = 96

The area of the rectangle is 96.

If the area of the square is 100, and the area of the rectangle is 96, then we can conclude that the area of a square is larger.

If a rectangle and a square have the same perimeter then Square will have a larger area.

Suppose length of rectangle is 6 cm and breadth is 2 cm.

So, Area of a rectangle = length ×  breadth

                                  =(6×2) cm²

                                  = 12 cm²

Given that,

Perimeter of rectangle = Perimeter of square

2× (length + breadth)   =  4×side

Side = [tex]\frac{2 ( length + breadth)}{4}[/tex]

Side =  [tex]\frac{2 (6+2)}{4}[/tex]

Therefore, side = 4 unit.

Now,  Area of Square = (side)²

                                    = ( 4 )²

                                      16 unit²

Hence, Area of square (16) is more than area of rectangle (12).

If  a customer buys 2 cantaloupes and p pounds of potatoes on friday from the local farmers' market, the total cost equation would be A. C = 0.63p + 7.

Equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation also often contain an algebra. Algebra is used in maths when you do not know the exact number in a calculation.

Based from the question above, we don't know the exact number of potato that the customer bought. We only know that the customer buys p pounds of potatoes.

Potato price = $0.90

on Friday, the potato price is (30% discount)

= 0.90 - (0.90 * 30%)

= $0.63

Since the customer buys for p pounds of potatoes, therefore the total cost of potatoes

= $0.63 * p

= 0.63p

From the question above, we know that the customer buys 2 cantaloupes.

cantaloupes price = $3.50 each

The total cost for cantaloupes

= 2 * $3.50

= $7

Now, let's put it into the total cost equation to find the answer from the multiple choice.

Total cost (c) = 0.63p + 7

Answer:

y = (-6)*x - 16

Step-by-step explanation:

The slope-intercept form of a line is given by the equation:

y = mx + b

where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

In this case, the line passes through the point (-4,8) and has a slope of -6, so we can plug these values into the equation to find the y-intercept:

y = (-6)*x + b

We know that the line passes through the point (-4,8), so we can substitute these values into the equation to solve for b:

8 = (-6)*(-4) + b

8 = 24 + b

b = -16

Therefore, the equation of the line in slope-intercept form is:

y = (-6)*x - 16

To use the midpoint rule to estimate the value of the double integral of a function f(x,y) over the region R=[0,6]x[0,6], we need to divide the region R into a grid of subintervals, with m subintervals in the x-direction and n subintervals in the y-direction. In this case, m=n=3, so we divide each side of the region R into 3 subintervals of equal length.

The midpoint rule states that the approximation of the integral is given by the sum of the areas of the rectangles formed by the subintervals, where the height of each rectangle is given by the value of the function at the midpoint of the subinterval.

To implement the midpoint rule, we first need to determine the width and height of each subinterval. The width of the subintervals in the x-direction is given by (6-0)÷3 = 2, and the width of the subintervals in the y-direction is also given by 2. The height of each rectangle is given by the value of the function f at the midpoint of the subinterval.

We can then evaluate the double integral by summing the areas of the rectangles formed by the subintervals. For example, the first rectangle would have a height equal to the value of the function at (0+2)÷2=1 and a width of 2, so its area would be 2f(1,1). The second rectangle would have a height equal to the value of the function at (2+4)÷2=3 and a width of 2, so its area would be 2f(3,1)

An explicit description of Nul A is given by the set of vectors {[0, 0, 1, 0], [0, 0, 0, 1]}.

What is the explicit description of a null space matrix?

To find an explicit description of the null space of matrix A, we can find a spanning set of vectors that span the null space.

The null space of matrix A, denoted Nul A, is the set of all vectors x that satisfy the equation Ax = 0. In other words, the null space consists of all vectors that are mapped to the zero vector by the matrix A.

To find a spanning set for Nul A, we can use the following steps:

Row reduces the matrix A to a reduced row-echelon form using elementary row operations.

Identify the free variables in the row-reduced matrix.

For each free variable, create a vector with a 1 in the position corresponding to the free variable and 0's in all other positions.

The set of vectors created in step 3 form a spanning set for Nul A.

For example, consider the matrix A = [1, 2, 3, 0; 0, 0, 1, 0]. To find a spanning set for Nul A, we can row reduce the matrix to reduced row-echelon form:

[1, 2, 3, 0] -> [1, 2, 3, 0]

[0, 0, 1, 0] -> [0, 0, 1, 0]

The matrix is already in reduced row-echelon form, so there are no more elementary row operations to perform. The free variables in this matrix are the third and fourth columns, which correspond to the variables x3 and x4, respectively. Therefore, we can create the following vectors:

x3 = [0, 0, 1, 0]

x4 = [0, 0, 0, 1]

These vectors form a spanning set for Nul A, as they are linearly independent and span the null space.

Hence, an explicit description of Nul A is given by the set of vectors {[0, 0, 1, 0], [0, 0, 0, 1]}.

The flow of air is drawn toward the ball by the low pressure area that surrounds it. As a result, the fluid (air) jet flows across the ping pong ball's curved surface. The "Coandă effect" refers to this phenomena.

The airflow's propensity to stick to the ball's surface is the Coandă effect in this situation. This indicates that the streamlines are curved at the ball's surface, with a radius of curvature roughly equal to the ball's radius. This curvature produces a pressure gradient, much like it does in the theory of lift, which I assume to be constant over the surface:

The measure of ∠CDE is 54°

What is measure ?

When attributes of an item or event are quantified, they can be compared to other objects or events and utilized as a basis for comparison. Determining how big or little a physical quantity is in relation to a fundamental reference quantity of the same kind is the process of measurement, in other words.

A measure is a piece of mathematics that expresses the size of sets in numerical terms. A different method of determining how large a set is is embodied by each unique measure. Initially, it could seem as though a set's cardinality is the only natural way to determine its size.

<CDE = far arc - near arc / 2

i.e

<CDE = arcCBE - arcCE / 2

arcCE = 126°

arcCBE = 360° - 126° = 234°

<CDE = (234° - 126°)/ 2

<CDE = 108 / 2

<CDE = 54°

The rate at which the distance between the buses is changing when they are 13 miles apart is -85.25 mph.

Given, two buses are driving along parallel freeways that are 12 miles apart, one heading east and the other heading west.

Assuming that each bus drives a constant 58 mph.

Now, we have to find the rate at which the distance between the buses is changing when they are 13 miles apart and heading towards each other.

Considering distance as a function of time,

D = f(t) = √((12)² + (13 - 116t)²)

f'(t) = (13 - 116t)(-116)/√((12)² + (13 - 116t)²)

f'(0) = (13 - 116(0))(-116)/√((12)² + (13 - 116(0))²)

f'(0) = -1508/√(144 + 169)

f'(0) = -1508/√313

f'(0) = -85.25

So, the rate of distance is decreasing at the rate of 85.25
