Answer:
3,136cm^2
Step-by-step explanation:
A square has 4 sides that are all equal to each other. This means the perimeter can be divided by the number of sides to find the measurement of each side.
224cm ÷ 4 = 56cm
Each side is 56cm
To find the area, we must multiply base and height. Since it is a square, it will be 56cm × 56cm.
56cm × 56cm = 3,136cm^2
Answer:
3136cm²
Explanation:
to find the area of the square, we first need to find the length of one of its sides. the perimeter is the total length of all 4 sides, so we can divide it by 4 to find the length of each side.
224 ÷ 4 = 56
now, we can square this to find the area of the square:
56² = 56 × 56 = 3136
thus, the area of the square is 3136cm².
i hope this helps! :D

What are the possible rational roots of x³ X² 10x 8 0?
The Possible rational roots of the equation "x³- x² - 10x - 8 = 0" are x = -1 , x = -2 and x = 4 .
The Rational roots of the equation are defined as the values of the variable such that value of the entire equation becomes 0 .
the function is f(x) = x³- x² - 10x - 8 ,
By the Rational Roots Theorem , we know that is p/q is the root of the equation , then p is a factor of 8 and q is a factor of 1 .
the possible values of p are ±1 , ±2 , ±4 , ±8 , and
the possible values of q are ±1 .
So , the possible rational roots (p/q) are ±1 , ±2 , ±4 , ±8 .
So , on substituting the all the possible values of the rational roots ,
we get ;
f(1) = (1)³- (1)² - 10(1) - 8 = -18
f(-1) = (-1)³- (-1)² - 10(-1) - 8 = 0
f(2) = (2)³- (2)² - 10(2) - 8 = -24
f(-2) = (-2)³- (-2)² - 10(-2) - 8 = 0
f(4) = (4)³- (4)² - 10(4) - 8 = 0
f(-4) = (-4)³- (-4)² - 10(-4) - 8 = -48
f(8) = (8)³- (8)² - 10(8) - 8 = 360
f(-8) = (-8)³- (-8)² - 10(-8) - 8 = -446.
we get , the value as 0 at x = -1 , -2 and 4 .
Therefore , the possible rational roots are x = -1 , x = -2 and x = 4 .

How do you find the base of an isosceles triangle with legs?
We can find the base of the isosceles triangle with legs using the formula:
2 × sqrt ((hypotenuse) ^ 2 - (altitude)^2) = base
Let us assume that the leg of the isosceles triangle is 'h' and one side is 'a'. Let the base be 'x'.
As there is a leg (altitude) in the isosceles triangle, then it forms a right triangle in the isosceles triangle, such that the sides form the hypotenuse.
Therefore, by using the Pythagoras' theorem,
hypotenuse ^ 2 = (altitude)^2 + (base / 2)^2
Hence, we get the base by deriving this expression from the above formula:
2 × sqrt ((hypotenuse) ^ 2 - (altitude)^2) = base

What is the difference between continuous function and discontinuous function?
A continuous function is a function that is defined for all values of the independent variable, and its graph has no breaks or jumps. A discontinuous function is a function that is not continuous, meaning there are values of the independent variable at which the function is undefined or has a break or jump in its graph.
A continuous function is a function that can be graphed without any breaks or jumps. This means that the graph of a continuous function is a single, unbroken curve that passes through all its points. Furthermore, a continuous function is defined for all values of the independent variable. This means that the function is defined for all points in its domain. On the other hand, a discontinuous function is a function that is not continuous, meaning there are values of the independent variable at which the function is undefined or has a break or jump in its graph. This means that the graph of a discontinuous function will have jumps or breaks. Furthermore, a discontinuous function is not defined for all values of the independent variable, meaning that there are certain points in the domain for which it is not defined. In conclusion, the main difference between continuous and discontinuous functions is that a continuous function is defined for all values of the independent variable and has no jumps or breaks in its graph, whereas a discontinuous function is not defined for all values of the independent variable and has jumps or breaks in its graph.

according to us postal regulations, the perimeter of the smallest end plus the length of a parcel sent by mail may not exceed 108 inches. what is the largest possible volume of a rectangular parcel where the smallest end is a square that can be sent by mail? what are the dimensions of the parcel of largest volume?
The largest possible volume of a rectangular parcel where the smallest end is a square that can be sent by mail according to USPS regulation is 11664 cubic inches.
The volume of a rectangular parcel with dimensions l, w, and h is lwh. We can express the volume of the rectangular parcel in terms of one variable, say l, as lwh = l(108 - 2l)h. We want to maximize this expression subject to the constraint that l is a positive number less than 54 (the maximum value for l that still allows the parcel to fit within the 108-inch limit).
Taking the derivative of the volume with respect to l and setting it equal to zero, we find that the maximum volume occurs when:
l = (27 inches)
At this value, the dimensions of the parcel are:
l = 27 inches
w = 27 inches
h = 2(108 - 2l) = 2(72) = 144 inches
The volume of the parcel is then:
lwh = (27)(27)(144) = 11664 cubic inches
This is the largest possible volume of a rectangular parcel where the smallest end is a square that can be sent by mail according to USPS regulations.

It helps to identify how big or small a quantity is as compared to other thing having same parameter of measurement.
NOTE: Things which have different measurement cannot be compared by ratio;
Example: 1 litre of milk cannot be in ratio with 1 kg of sand, as milk is measured in volume and sand is in weight.
Solution:
Given, ratio of model of plane and actual plane = 1 : 40
x = 7.5 inches
Let, x be the dimension of model of the airplane
y be the dimension of actual airplane

In order to present geometric forms in a two-dimensional plane and learn about their properties, coordinate geometry is a crucial area of mathematics.
The center of that ellipse is the midpoint of the major axis,
half way between (0,0) and (13,0) on line y=0.
The coordinates of that midpoint are the averages of the coordinates of the vertices.
The midpoint is (6.5,0) , and that is the center of the ellipse.
The distance from the center to each vertex is called the semi-major axis and represented as a .
In this case a=6.5 .
Half of the minor axis is called the semi-minor axis and is represented with b .
That is the distance from the center to each co-vertex.
In this case b= 12/2=6 .
The distance from the center to each focus is represented with c ,
and is related to a and b by a²=b²+c²

Let's find out the cost of oranges first. Multiply the first equation by -2
-18A - 12Y = $-66
18A + 20 Y = $80
8Y = $14
Y = $1.75
Now let's put 1.75 back in the Y to find the cost of apple

How do you calculate decay from half-life?
Using the formula T1/2 = 0.693/λ, we may determine decay from half-life.
What is half-life?The half-life is the amount of time needed for half of the initial population of radioactive atoms to decay.
T1/2 = 0.693/λ describes the relationship between the half-life, T1/2, and the decay constant.
A percentage is used to represent the degradation rate.
Simply decreasing the percent and dividing it by 100 yields the decimal equivalent.
The decay factor b = 1-r can therefore be calculated.
For instance, the exponential function's decay rate is 0.25, and the decay factor b = 1- 0.25 = 0.75 if the rate of decay is 25%.
Nearly all decay processes that are exponential, or nearly exponential, are referred to by the phrase "half-life".
Therefore, using the formula T1/2 = 0.693/λ, we may determine decay from half-life.

Help me please with this
The domain and the range of this function shown in the graph include the following;
Domain = -5 ≤ x < 1.Range = -4 ≤ y < 7.How to identify the domain and range of this graph?In Mathematics, the horizontal extent of a graph represents all domain values and they are read and written from smaller to larger numerical values, and from the left of a graph to the right.
Furthermore, the vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.
Note: Each interval on this graph represent 1 unit and the less than or equal to (≤) would be used because the dotted point is shaded (closed).
By critically observing the graph shown above, we can reasonably and logically deduce the following:
Domain = -5 ≤ x < 1 or [-5, 1].
Range = -4 ≤ y < 7 or [-4, 7].
