Which combination of integers can be used to generate the Pythagorean triple (5,12,13)

Kitty [74]

Answer:

x=3 and y=2

Step-by-step explanation:

The pythagorean triples are generated by two integrers x and y that can be found by solving the following system of equations:

$\left \{ {{x^{2}-y^{2}=5}\atop {2xy=12}} \atop {x^{2}+y^{2}=13}}\right.$

Solve the system of equations, and we get that the solution is x=3 and y=2.

Therefore, the combination of integrers that ca be used to generate the pythagorea triple are: x=3 and y=2

Find the sun and express it in simplest form.(-3s-4c+1)+(-3s+3c)

DiKsa [7]

Answer:

-6s-c+1

Step-by-step explanation:

(-3s-4c+1)+(-3s+3c)

We have been given the above expression. To find the sum, we simply collect the like terms and combine them;

(-3s-4c+1)+(-3s+3c) = -3s + -3s -4c + 3c + 1

-3s + -3s -4c + 3c + 1 = -3s - 3s + 3c - 4c + 1

-3s - 3s + 3c - 4c + 1 = -6s - c + 1

Therefore;

(-3s-4c+1)+(-3s+3c) = -6s-c+1

In a first-order decomposition reaction. 52.3% of a compound decomposes in 8.6 min. How long (in min) does it take for 80.3% of

rusak2 [61]

Answer:

13.20 min

Step-by-step explanation:

Rate of the reaction is a measure of the rate of decomposition of the compound.

Rate (R) = Concentration (C) ÷ time (t)

C1/t1 = C2/t2

C1 = 52.3% = 0.523

t1 = 8.6 min

C2 = 80.3% = 0.803

t2 = C2t1/C1 = 0.803×8.6/0.523 = 13.20 min (to 2 decimal places)

The price of third MP3 Player is $58.4

Further explanation:

Given

Price of first MP3 player= p1= $56

Price of second MP3 Player = p2= $62

Price of third MP3 Player=?

Average = X = $58.80

The formula for average is:

$X =\frac{Sum}{No.\ of\ items}$

We have 3 items.

Putting the values

$58.80=\frac{56+62+p_3}{3}\\58.80*3=118+p_3\\176.4=118+p_3\\p_3=176.4-118\\p_3=58.4\ dollars$

The price of third MP3 Player is $58.4
