Answer:

See below.

Step-by-step explanation:

Again, another great question!

This should be under physics, as it involves Work = Force * Distance. As Anne pushes the wheelbarrow with a force of 70 Newtons with respect to an angle of 50 degrees horizontal, the horizontal force is 70( cos 50 ). The distance over which the work is done is 25 meters, so work should be -

Work = ( 70( cos 50 ) )( 25 ),

Work = ( About ) 1124.87 Joules

<u><em>The work done when Anne pushes the wheelbarrow a distance of 25 meters, is 1124.87 Joules</em></u>

Wait let me know that the .12 means in the first question and i will fix the answer

int (x)(cosx) dx 

u=x      ----> take derivative     du=dx
dv=cosx    -----> take integral  v=sinx

now use integration by parts 

u v - int (v)du
x sinx - int (sinx) (1) dx=

x sinx  - (-cos(x)) + c =

answer is = x sinx + cosx + c

Solve 3x−5 = 9. <br> x = −3 <br> x = 2 <br> x = 7 <br> x = 8
Nina [5.8K]

Solve 3x−5 = 9:


Add 5 to both sides, to isolate 3x on the left side: 3x = 5+9 = 14


Solve this for x: x = 14/3
