Answer:Nov 20, 2014 - In the second part of the activity, mass is added to the toy car to illustrate Newton's Second Law. ... If the object is in motion, the force changes its velocity. ... on an object is equal to the mass of the object times its acceleration.
Step-by-step explanation: think of newtons first law and start from there and you should get it on your first thought on your problem.
Here's what we know:
4t = 7/10 (4 tasks take 7/10 of an hour)
Divide both sides by 4:
4t / 4 = 7/10 / 4
t = 7/40
So each task is 7/40 of an hour
7/40 n = 1 (Now we want to find the number of tasks completed in 1 hour)
Multiply both sides by 40/7:
n = 40/7
Converting improper fraction to a mixed number:
n = 5 5/7
So the robot will complete 5 5/7 tasks in an hour. If the answer is looking for fully finished tasks and not partially done ones, the you need to round down to 5.
Answer:
( 1 ) ,
( 2 )
Step-by-step explanation:
Taking the function and it's inverse, it should be the following property -
- this therefore makes the functionality " " equivalent to 576 itself.
For this second part here let's consider the portion " " firstly. As you can see from the table, - 7 should represent the x - value, hence . Now for this second bit here, we have to take the inverse - making the what should have been the x - value, now the f( x ) value. Therefore, .
This would make = = 13.
Answer:
C -2 or 1
Step-by-step explanation:
So from the equation you have x^2-x-1=-2*x+1
x^2-x-1+2*x-1=0
x^2 +x -2 =0
D= 1^2 -4*(-2)= 1+8=9
x = (-1+-3)/2
So x is either (-1+3)/2=2/2=1
or (-1-3)/2=-2
