Determine the equation of the line that passaes through (2,4) and is perpendicular to thr line x+y=0

Answer:

5 pi:

15.7

Step-by-step explanation:

Square  root : 15

So, 15.7 is GREATER than 15.

I really hope I helped!

Since  15.7 is GREATER than 15. so 5 pi greater than the square root of 225.

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

Perfect square are those integers whose square root is an integer.

Let x-a be the closest perfect square less than x,

and let x+b be the closest perfect square more than x, then we get: x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).

Then, we get:

[tex]\sqrt{x-a} < \sqrt{x} < \sqrt{x+b}[/tex]

We know that the value of pie is 3.14

then 5 pi = 5 x 3.14

= 15.7

Now, Square root of 225 which is perfect square;

√225 = 15

Thus, 15.7 is GREATER than 15.

Therefore,  5 pi greater than the square root of 225.

Answer:

it is irrational,because the product of an irrational number and a non zero rational number is irrational

Answer:

(0, - 2 ) and (3, 4 )

Step-by-step explanation:

Given the equations

3y = 2(x² - 3) , that is

3y = 2x² - 6 → (1)

2x - y = 2 (add y to both sides )

2x = 2 + y ( subtract 2 from both sides )

2x - 2 = y → (2)

Substitute y = 2x - 2 into (1)

3(2x - 2) = 2x² - 6

6x - 6 = 2x² - 6 ( subtract 6x - 6 from bpth sides )

0 = 2x² - 6x ( factor out 2x from each term )

0 = 2x(x - 3)

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

x - 3 = 0 ⇒ x = 3

Substitute these values into (2) for corresponding values of y

x = 0 : y = 2(0) - 2 = 0 - 2 = - 2 ⇒ (0, - 2 )

x = 3 : y = 2(3) - 2 = 6 - 2 = 4 ⇒ (3, 4 )

Answer:

2x+7

Step-by-step explanation:

3x +(-x) = 3x - x, so it's 2x

12 + (-5) is the same situation, just being 12 - 5, so it's 7.

putting them together leaves you with 2x+7

Answer:

2.56 gallons per minute!

Step-by-step explanation:

44.8 gallons - 32 gallons = 12.8 gallons

12.8 gallons in 5 minutes - so we need to find the unit rate (per one minute)

12.8/5 = 2.56

2.56 gallons per minute!

Answer:

10

Step-by-step explanation:

Since s is the side length substitute s for 5:

0.4(5)^2

then do 5^2 which will give you:

5 x 5 = 25

then multiply 0.4 and 25 which is:

0.4 x 25 = 10

You could also do this:

0.4 x 5 = 2

2^2 = 2 x 2 = 4

But The correct answer would be 10 because you would do the exponents first because it is in pemdas

Answer: Part A: a square pyramid Part B: 84 square feet

Step-by-step explanation:

Part A: The shape will have a base that is a square with triangles on each of its edges that connect at a point at the top.

Part B: The amount of nylon needed is the surface area of the net. There is a square and two triangles. The square has a side length of 6 so its area will be 6*6=36 square feet. Each triangle has a base of 6 and a height of 4 so each of their areas will be [tex]\frac{6*4}{2}=12[/tex] square feet. Adding up the area of the 4 triangles and the square gives us 4*12+36=84 square feet.

Answer:

Yes

Step-by-step explanation:

The area of a square is equal to the length squared.

So, the length of one side of the original floor is √400 which equals 20.

If you increase the length by 1, the area of the dance floor is 21 squared.

21 * 21 is certainly a rational number.

Answer:

Step-by-step explanation:

I think so, yes.

The area of a square is A = s*s where s is the length of the side

s^2 = 400

sqrt(s^2) = sqrt(400)

s = 20

If you increase each dimension by one foot you get 21 * 21 for the area of the new ballroom.

The result is rational. That's because the square root was rational when you found 20.

Area = 21 * 21 = 441 which is rational.
