Answer:
150 feet and reached a height of 100 feet at its highest point.
You wanna get the y by itself. So you will subtract 11.9 then move it to the other side. so that is 10.5y = -11.9x +178.5. Then divide everything by 10.5. Then you get y = -11.9x/10.5+17. 11.9x/10.5 is because you cant put 10.5 into 11.9 evenly so you leave it as a division problem.
Step-by-step explanation:
x^2+2x+7y=15
7y=15-x^2-2x
y=15/7-1/7x^2-2/7x , x ∈ all real numbers
Answer:
Work done = 1.69 lb-ft.
Step-by-step explanation:
Work required to stretch a spring 2 feet beyond its natural length W = 12 ft-lb
By Hook's law
12 =
12 = 2k
k = 6 lb per feet
Now we have to find the work done to stretch the spring 9 inch or feet beyond its natural length.
We again use the Hook's law.
lb-ft
Therefore, work done to stretch the spring 9 in. beyond the its natural length will be 1.69 lb-feet.
