Answer:

[ 0 ]

Step-by-step explanation:

The order of the matrix [ 3 1 1 ] is 1 by 3 and the order of the other matrix is 3 by 1 so this means that the order of the answer matrix is 1 by 1. So we multiply matrices row by columns.

[ 3 1 1 ] × | 2|

| -6|

| 0|

[ 3 × 2 + 1 × -6 + 1 × 0 ]

[ 6 - 6 + 0 ]

[ 0 ]

Anestetic [448]

Answer:

<em>The size of a sundae and the amount of calories it contains.</em>

Step-by-step explanation:

The answer choice is the only one with a positive correlation, because it is the only one that isn't depleting or going down in size. No matter if you eat the sundae or what size it becomes, the calories it contains will still be the same for the whole amount.

When a car travels, gas is used and it depletes. As a snowball does when it melts. And "the temperature on Tuesday" has no correlation involved at all

The period T (in seconds) of a pendulum is given by T=2\pi \sqrt((L)/(32)), where L stands for the length (in feet) of the pendu
Vsevolod [243]
The first thing we must do in this case is to rewrite the equation correctly:
 T = 2 * pi * root (l / 32)
 From here, we clear l:
 T / (2 * pi) = root (l / 32)
 l / 32 = (T / (2 * pi)) ^ 2
 l = 32 * (T / (2 * pi)) ^ 2
 Substituting values:
 l = 32 * (1.57 / (2 * 3.14)) ^ 2
 l = 2 feet
 Answer:
 
the length is:
 
l = 2 feet
