Answer:

3, 4, 5

Step-by-step explanation:

We are given the sets of numbers and we are supposed to find Which set of numbers could represent the lengths of the sides of a right triangle

So, we need to use Pythagoras theorem

Hypotenuse^{2} =Perpendicular^{2} +Base^{2}

1) 9,10,11

Hypotenuse = 11

So, using Pythagoras theorem

11^{2} =10^{2} +9^{2}

121=100 +81

121\neq 181

Since the given set does not satisfy the Pythagoras theorem.So, the given set  of number could not represent the lengths of the sides of a right triangle.

2)16, 32, 36

Hypotenuse = 36

So, using Pythagoras theorem

36^{2} =32^{2} +16^{2}

1296=1024 +256

1296\neq 1280

Since the given set does not satisfy the Pythagoras theorem.So, the given set  of number could not represent the lengths of the sides of a right triangle.

3)8, 12, 16

Hypotenuse = 36

So, using Pythagoras theorem

16^{2} =12^{2} +8^{2}

256=144 +64

256\neq 208

Since the given set does not satisfy the Pythagoras theorem.So, the given set  of number could not represent the lengths of the sides of a right triangle.

4)3, 4, 5

Hypotenuse = 5

So, using Pythagoras theorem

5^{2} =4^{2} +3^{2}

25=16 +9

25\=25

Since the given set satisfy the Pythagoras theorem.So, the given set  of number could represent the lengths of the sides of a right triangle.

Hence 3, 4, 5 is the set of numbers could represent the lengths of the sides of a right triangle

using a^2 +b^2 = c^2 plug in any of the numbers i plugged in 
3^2 +4^2 which gave me 9+16 and that is 25 and 5^2 is 25

Use the quadratic formula to find the complex solution to the equation 10x^2 - x + 9 = 0.
Jlenok [28]

We have the following:

10x^2-x+9=0

solving:

\begin{gathered} 10x^2-x+9=0 \\ 10x^2-x+9-9=-9 \\ 10x^2-x=-9 \\ \frac{10}{10}x^2-\frac{x}{10}=-\frac{9}{10} \\ x^2-\frac{x}{10}+(-\frac{1}{20})^2=-\frac{9}{10}+(-\frac{1}{20})^2 \\ (x-\frac{1}{20})^2=-\frac{359}{400}\rightarrow(x-\frac{1}{20})=\sqrt[]{-\frac{359}{400}} \\ x=\frac{1}{20}+i\frac{\sqrt{359}}{20} \\ x=\frac{1}{20}-i\frac{\sqrt{359}}{20} \end{gathered}

lyudmila [28]

Answer:

12 cm difference

Step-by-step explanation:

√64 cm² = 8 cm

8 cm x 4 = 32 cm perimeter

√121 cm² = 11 cm

11 cm x 4 = 44 cm perimeter

44 cm - 32 cm = 12 cm difference
