Answer:

17.2

Step-by-step explanation:

(14)2+(10)2=

 c2\,\,c^{2}c2

Use the Pythagorean Theorem.

196+100=196+100=196+100=

 c2\,\,c^{2}c2

Simplify.

296=296=296=

 c2\,\,c^{2}c2

Simplify.

±296=\pm\sqrt{296}=±296

​=

 c2\,\,\sqrt{c^{2}}c2

​

Square root both sides.

17.204650...=17.204650...=17.204650...=

 c\,\,cc

Simplify. Ignore negative root, as length must be positive.

17.2≈17.2\approx17.2≈

 c\,\,cc

Round to the nearest tenth.

Answer:

15.6=c

Step-by-step explanation:

(12)^2+(10)^2=c^2

144+100=c^2

244=c^2

square root of both sides=244= square root c^2

15.620499=c

15.6=c

Help pleaseeeeeeeeeeee
ollegr [7]

Answer:

Step-by-step explanation:

The temperature at a given altitude is

y = 36 - 3x

The temperature on the surface of the planet is the point (0,t) where t is the temperature for the given height.

y = 36 - 3*0

y = 36

So at the surface of the planet is 36 degrees C.

======================

Effectively it is the slope of the equation which is - 3

So ever km going up will mean a loss of 3 degrees. I think they want you to write -3

is there a relationship between exterior angles that lie on the same side of a transversal? interior angles that lie on the same
HACTEHA [7]

Answer:

No

Step-by-step explanation:

In both exterior and interior angles on the same side of the transversal, one of the angles will be acute and the other one will be obtuse making them different. Therefore, there is no relationship between them.

Solve the following system
scZoUnD [109]

Answer:

{x = -4 , y = 2 ,  z = 1

Step-by-step explanation:

Solve the following system:

{-2 x + y + 2 z = 12 | (equation 1)

2 x - 4 y + z = -15 | (equation 2)

y + 4 z = 6 | (equation 3)

Add equation 1 to equation 2:

{-(2 x) + y + 2 z = 12 | (equation 1)

0 x - 3 y + 3 z = -3 | (equation 2)

0 x+y + 4 z = 6 | (equation 3)

Divide equation 2 by 3:

{-(2 x) + y + 2 z = 12 | (equation 1)

0 x - y + z = -1 | (equation 2)

0 x+y + 4 z = 6 | (equation 3)

Add equation 2 to equation 3:

{-(2 x) + y + 2 z = 12 | (equation 1)

0 x - y + z = -1 | (equation 2)

0 x+0 y+5 z = 5 | (equation 3)

Divide equation 3 by 5:

{-(2 x) + y + 2 z = 12 | (equation 1)

0 x - y + z = -1 | (equation 2)

0 x+0 y+z = 1 | (equation 3)

Subtract equation 3 from equation 2:

{-(2 x) + y + 2 z = 12 | (equation 1)

0 x - y+0 z = -2 | (equation 2)

0 x+0 y+z = 1 | (equation 3)

Multiply equation 2 by -1:

{-(2 x) + y + 2 z = 12 | (equation 1)

0 x+y+0 z = 2 | (equation 2)

0 x+0 y+z = 1 | (equation 3)

Subtract equation 2 from equation 1:

{-(2 x) + 0 y+2 z = 10 | (equation 1)

0 x+y+0 z = 2 | (equation 2)

0 x+0 y+z = 1 | (equation 3)

Subtract 2 × (equation 3) from equation 1:

{-(2 x)+0 y+0 z = 8 | (equation 1)

0 x+y+0 z = 2 | (equation 2)

0 x+0 y+z = 1 | (equation 3)

Divide equation 1 by -2:

{x+0 y+0 z = -4 | (equation 1)

0 x+y+0 z = 2 | (equation 2)

0 x+0 y+z = 1 | (equation 3)

Collect results:

Answer:  {x = -4 , y = 2 ,  z = 1
