In the case that a scientist cools three gases in an experiment, the change in temperature will be negative for the experiment. This is because cooling results in a temperature lower than the original temperature. For example, a gas originally at 25°C when cooled to 20°C has a temperature change of -5°C.

The height and radius of a right cylinder are each 6 cm.
Marianna [84]
The volume of a cylinder can be found using the formula πr²h.

V = (3.14)(6)²(6)
V = 678.24 cm³

From the answer choices it will be:

V = π(6)²(6)
V = 216π cm³

So the answer is answer choice B.

Hope this helps :)

What equation is parallel to y= -1/4+5 and passes through (2,-3)? <br> HELPPPPP PLEASE!!!!
IrinaVladis [17]

Answer:

y = -1/4x - 5/2.

Step-by-step explanation:

I am assuming you mean y = -1/4x + 5.

This has slope of -1/4 so the required equation has the same slope ( as they are parallel).

Using the point-slope form of the equation of a line:

y - (-3) = -1/4(x - 2)

y + 3 = -1/4(x - 2)

y = -1/4x + 1/2 - 3

y = -1/4x - 5/2

Boat A is docked at (4.2, −2) and Boat B is docked at (−5.2, −2). The boats are ____ units apart.
Reil [10]

Answer:

9.4 units

Step-by-step explanation:

Step one:

given data'

We are given the coordinates

x1=4.2

x2=-5.2

y1=-2

y2=-2

Required

The distance between the points

Step two:

The expression for the distance is

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-5.2-4.2)²+(-2+2)²)

d=√((-9.4)²

d= √88.36

d= 9.4 units
