Answer:

Step-by-step explanation:
Power is defined by work over time. In physics, work can be defined as the energy transferred over from an applied force over some distance. As a formula:
, where F = force applied and d = distance that force is applied over.
*It is worth noting that F must be parallel to the distance travelled. If it is perpendicular, no work is done, and if it is at an angle, find the parallel component and use that for F.
In this case, the force applied must counter the force of gravity on Martha, which is given by
, where m = Martha's mass and g = gravitational constant 9.8 m/s/s. Therefore,
. Since she raises her body 4.0 meters, the work done must be
.
Since power is equal to work over time and t = 2.3 seconds, we have:
(to two significant figures)
Answer:
The required paint for a total of
is approximate 6 gallons
Step-by-step explanation:
we know that
To find how much paint would I need to buy to paint the walls of all three bedrooms, calculate the area of all three bedrooms
<em>Master Bedroom</em>
The area is equal to

<em>2 Bedroom</em>
The area is equal to

<em>3 Bedroom</em>
The area is equal to

The total area is equal to
A=A1+A2+A3

Approximate one gallon of paint covers 250 square feet
so

Function because nothing repeats in the domain
Answer:
×=36
Step-by-step explanation:
46+1/6X-21=31
25+1/6X=31
1/6X=31-25
1/6X=6
X=36
