Answer:
4608
Step-by-step explanation:
2cubed=8
Brackets first= 4x6=24
24squared=576
8x576=4608
40% of 280 is 112 so to increase by 25% it must increase by 28
ANSWER:
4242.64 lbs*ft
STEP-BY-STEP EXPLANATION:
To better understand we make a sketch of the situation:
Where,
Distance ||PQ|| = 100 ft
Force (F) = 60 lbs
The angle between force and displacement is 45°
Component of force along displacement is F * Cos 45°
The total work is calculated by means of the formula shown in the statement:
![\begin{gathered} W=F\times||PQ||\times\cos45\degree \\ \\ W=60\times100\times\cos45\degree \\ \\ W=4242.64\text{ lbs*ft} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20W%3DF%5Ctimes%7C%7CPQ%7C%7C%5Ctimes%5Ccos45%5Cdegree%20%5C%5C%20%20%5C%5C%20W%3D60%5Ctimes100%5Ctimes%5Ccos45%5Cdegree%20%5C%5C%20%20%5C%5C%20W%3D4242.64%5Ctext%7B%20lbs%2Aft%7D%20%5Cend%7Bgathered%7D)
