Answer: y=-3/5x-4
Step-by-step explanation:
We can substitute this into point slope form, which is y-y1=m(x-x1).
y-(-1)=-3/5(x-(-5)
y+1=-3/5(x+5)
y+1=-3/5x-3
y=-3/5x-4
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)
6x+2x-6=4x+x-18
8x-6-4x-x=-18
3x=-18+6
3x=-12
X=-4

Answer:
True False True
Step-by-step explanation:
1. A circle has 360 degrees in its interior. 360 - 130 (this is given) degrees = 230 degrees. This means it's TRUE
2. The area of the shaded sector is the degrees in the central angle that contains the sector, multiplied by the area of the circle. This means that the area is pi*r^2*angle. The radius is 10, and the angle is 230 degrees, so the answer is 100*230/360 pi = 23000/360 pi, which simplifies to 575/9 pi. This is FALSE.
3. The area of the shaded sector is area of the circle - area of the shaded sector. The area of the circle is pi r^2, which is 100 pi. 100 pi - 575/9 pi = 325pi/9, so this is TRUE
