Answer:
Step-by-step explanation:
Data Given: m = 70 kg , g = 9.8 ms^-2, h =10m.
For this case we can use the following formula:
For this case we need to find an expression for the force in terms of the distance. And since on this case the total distance is 10 m long we can write the expression like this:
The only acceleration on this case is the gravity and if we replace the values given we got:
Now we can find the required work with the following integral:
9,334,635, i believe , is your answer
Answer: -12
Step-by-step explanation:
3(-2)^3 - 2(-2)^2 - 9(-2) + 2 = N
3(-8) - 2(4) - 9(-2) + 2 = N
-24 - 8 + 18 + 2 = N
-12 = N
Answer:
The equation is y= 30 + 0.25x
Step-by-step explanation:
So y is your monthly cost. 30 is the constant because it is always a 30 dollar charge per month. Now it is 0.25 per minute so you need a variable, I like to use x but you can use anything. So we have y = 30 + 0.25x
Hopefully this helped you!
