Answer:
C. x > 15
Step-by-step explanation:
75% = 3/4
3/4 of 180 = 135
Answer:
From the analysis W1=W2.
they are directly related
Step-by-step explanation:
the work-done in stretching a spring can be expressed as
![W=\frac{1}{2}kx^2](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B1%7D%7B2%7Dkx%5E2)
where k= spring constant
x= change on length of spring
Hence for W1
Given data
x= 34-24= 10 cm
solving in terms of k we have
![W=\frac{1}{2}k*10^2\\\W=\frac{1}{2}k*100\\\W=50k](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B1%7D%7B2%7Dk%2A10%5E2%5C%5C%5CW%3D%5Cfrac%7B1%7D%7B2%7Dk%2A100%5C%5C%5CW%3D50k)
Hence for W2
Given data
x= 44-34= 10 cm
solving in terms of k we have
![W=\frac{1}{2}k*10^2\\\ W=\frac{1}{2}k*100\\\ W=50k](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B1%7D%7B2%7Dk%2A10%5E2%5C%5C%5C%20W%3D%5Cfrac%7B1%7D%7B2%7Dk%2A100%5C%5C%5C%20W%3D50k)
Answer:
(3 7/8, 2 3/4)
Step-by-step explanation:
To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.
Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.
Now we have our x and y coordinates.
(3 7/8, 2 3/4)
