Answer:
Work done = 3750 Joules
Step-by-step explanation:
The force acting in the body should be resolved to it's horizontal component before we can use ut to solve for the problem
Horizontal component= 150 * cos 60
Horizontal component= 150*0.5
Horizontal component= 75N
Work done= Force * distance
Work done= 75*50
Work done= 3750 Nm
Work done = 3750 Joules
For 9, do 0.5*6*9.2*5 to get the total area of the visual triangles, add that to 0.5*6*4.1*5 to get the area of the pentagon and you should get 199.5 cm^2for 10, do 0.5*6.9*8*12 to get the total area of the figure and you should get 331.2 cm^2
Here it would be image of triangular prism i believe.
Answer:
Step-by-step explanation:
So we have the expression:
And we want to find the value of the expression when t is -3.
So, substitute -3 for t:
Multiply:
Add:
Evaluate:
So, our answer is 9.
And we're done!
Answer:
The Y-Intercept is 7
Step-by-step explanation:
4x + y = 7
_________
-4x -4x
_________
y = -4x + 7 (This is now in y = mx + b form.)
B is the y-intercept of the formula and therefore 7 fits into that place.
