Explanation:

The square root undoes the squaring operation.

Think of a square that is 1 ft by 1 ft. Its area would be 1*1 = 1 sq ft.

Now imagine you told your friend "the area is 1 sq ft" and you didn't relay the side lengths. Your friend would use the square root to find the side length is 1 ft.

I'm not sure why your teacher is using plus minus notation when that is not correct. Saying [tex]\sqrt{1} = \pm 1[/tex] is not true. The result of a square root is simply one value only. If your teacher meant [tex]\pm \sqrt{1} = \pm 1[/tex], then it would be a true statement; however, there's no need to involve negative numbers for this problem.

Equations 1 and 4 would produce a parabola as they follow the general equation of a parabola.

Given equations are:

[tex]1)-5x^2+4x-7y+14 = 0\\\\2)-x^2 + 6x +y^2-8=0\\\\3)9x^2-12xy+4y^2+4x-y+5=0\\\\4)12x+6y-5y^2+14=0[/tex]

The general equation of a parabola

[tex]y = a(x^2+h^2-2xh)+k\\[/tex] or [tex]x= a(y^2+k^2-2yk)+h[/tex]

where h and k are vertices of the parabola.

Each equation follows the same pattern as the general equation of a parabola except the second and third equation

Therefore, equations 1 and 4 would produce a parabola as they follow the general equation of a parabola.

Answer:

598,402

Step-by-step explanation:

Let y = population at year x

x is the number of years since 1953, so for 1993, x = 40

a = population in 1953

y = a(1.08)^x

In 1993, the population is 13,000,000, so y = 13,000,0000 when x = 40.

13,000,000 = a(1.08)^40

13,000,000 = 21.7245a

a = 598,402

Answer: 598,402

Answer:

$100.70

Step-by-step explanation:

The difference between the total price ($434.50) and the sales price ($415) is the tax ($19.50).  To find the sales tax as a percentage of the sales price, divide the sales tax by the sales price and then multiply by 100:

19.50415(100)=4.70

Step-by-step explanation:

15,890.23 - Percentage decrease =

Answer:

KM=LM+KL.  If KM is 9 and LM is 5, then KM-LM=KL. So 9-5=4.  KL is 4.

Step-by-step explanation:

The value of KL will be equal to 4 in the line segment KM.

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

Given that point, L is on line segment KM. Given LM = 5 and KM=9. The value of the line segment KL will be calculated as below:-

KM = LM + KL.  

If KM is 9 and LM is 5, then,

KM-LM=KL.

KL =  9-5=4.  

KL = 4

Therefore, the value of KL will be equal to 4 in the line segment KM.
