What are square roots?

The opposite of squaring an integer is finding its square root. The result of multiplying a number by itself yields its square value, whereas the square root of a number may be found by looking for a number that, when squared, yields the original value. It follows that a, a = b if "a" is the square root of "b." Every integer has two square roots, one of a positive value and one of a negative value because the square of any number is always a positive number. For instance, the square roots of 4 are both 2 and -2. However, the square root of a number is typically only expressed as the positive value.

The value of a number's power 1/2 is the number's square root. It is the number whose product by itself yields the original number, to put it another way. It is symbolized by the character "." The number behind the square root sign is referred to as the radicand, whereas the square root symbol itself is known as a radical.

Answer:

70 points

Step-by-step explanation:

u = US points

c = Canadian points

n = Norwegian points

u = c + 2

n = c - 4

The values a = 10 and b = -6  will make the quadrilateral QRST a parallelogram

For the quadrilateral QRST to be a parallelogram, the diagonal lines TR and QS divide each other into two equal parts at P. Therefore, we can say:

For diagonal line QS, QP = PS:

-a + 27 = -6a + 77

-a + 6a = 77 -27

5a = 50

a = 50/5

a = 10

For diagonal line TR, TP = PR:

2b + 24 = -8b - 36

2b + 8b = -36 - 24

10b = -60

b = -6

Therefore, the value of a and b that will make the quadrilateral QRST a parallelogram is a = 10 and b = -6.

The dimensions of the enclosure that can be erected at minimum cost are 21.25 feet by 42.50 feet

From the question, the given parameters are

Area = 903 square feet

Shape = rectangle

From the question, we understand that:

One side of the area would be enclosed by the external wall of the store

If the dimensions of the area are Length (L) and Width (W), then we have

Area = LW

Perimeter = 2L + W

Rewrite as

A = LW

P = 2L + W

Substitute 903 for A in A = LW

LW = 903

Make W the subject

W = 903/L

Substitute W = 903/L in P = 2L + W

P = 2L + 903/L

Differentiate the equation

So, we have

P' = 2 - 903/L²

Set to 0

2 - 903/L² = 0

So, we have

903/L² = 2

This gives

L² = 903/2

Divide

L² = 451.5

Take the square roots

L = 21.25

Substitute L = 21.25 in W = 903/L

W = 903/21.25

Evaluate

W = 42.50

Hence, the dimensions of the enclosure are 21.25 feet by 42.50 feet

Slavery and oppression of other people impact others as it brings about discrimination and fear.

In the olden days, slavery was so lucrative that the Mississippi River valley produced more millionaires per capita than any other region of the country. With cash crops like tobacco, cotton, and sugar cane, the southern states of America developed into the country's economic engine.

In Africa, the slave trade had a terrible impact. A culture of lawlessness and violence was encouraged by the financial incentives provided to warlords and tribes to participate in the slave trade. Economic and agricultural development in a large portion of western Africa was virtually impossible due to depopulation and a persistent fear of enslavement.

The piecewise function on the graph is,

f(x) = {  1 -3x ; if x ≤ 2

        { 4-x    ; if x > 2

The graph of a piecewise function is given. The left function is defined on the interval x ≤ 2 and the right function is defined on the interval x > 2.

To find the functions we need two points on each function since both functions are straight lines.

First we will find the left function defined on x ≤ 2.

So the two points are (x₁, y₁) = (0,1) and (x₂, y₂) = (2, -5).

Now slope of the left function, m₁ = (y₂ - y₁)/(x₂ - x₁)

                                                        = -5 - 1/2 - 0

                                                        = -6/2

                                                        = -3

So the equation of the left function is,

y - y₁ = m(x-x₁)

⇒ y - 1 = -3(x-0)

⇒ y = 1 -3x

Thus the left function is f(x) = 1 -3x

Consider the right function.

The two points on the graph of the right function are (x₁, y₁) = (4,0) and (x₂, y₂) = (6, -2).

So slope of the second function, m₂ = (y₂ - y₁)/(x₂ - x₁)

                                                            = -2 - 0/6-4

                                                            = -2/2

                                                            = -1

Now equation for the right function is,

y - y₁ = m(x-x₁)

⇒ y - 0 = -1(x-4)

⇒ y = 4 -x

So the right function is f(x) = 4-x

Hence the piecewise function is,

f(x) = {  1 -3x ; if x ≤ 2

        { 4-x    ; if x > 2

Based on the results above, the slope of the tangent line to the curve at P(25,10) is 0.1.

Explanation:

P(25, 10) lies on the curve:

Q is the point (x, √x+5).

For any value of x, the slope of the secant line PQ is determined using the formula:

(a)When x=25.1

(b)When x=25.01

(c)When x=24.9

(d)When x=24.99

Based on the results above, the slope of the tangent line to the curve at P(25,10) is 0.1.

The value of x in the equation given as 1/6(x - 3) = 1/3(x + 2) is 7

The equation is given as

1/6(x - 3) = 1/3(x + 2)

From the question, we can see that the equation is a linear equation with one variable

As a general rule: linear equations are equations that have constant average rates of change.

We start by multiplying both sides of the equation by 6

So, we have the following equation

6 * 1/6(x - 3) = 1/3(x + 2) * 6

Next, we evaluate the products

So, we have the following equation

x - 3 = 2x + 4

Next, we collect the like terms

So, we have the following equation

2x - x = 3 + 4

Evaluate the like terms in the above equation

x = 7

This means that the solution of the equation is 7
