Answer and explanation:
Given : The position of an object moving along an x axis is given by 
where x is in meters and t in seconds.
To find : The position of the object at the following values of t :
a) At t= 1 s
b) At t= 2 s
c) At t= 3 s
d) At t= 4 s
(e) What is the object's displacement between t = 0 and t = 4 s?
At t=0, x(0)=0
At t=4, x(4)=14.24
The displacement is given by,
(f) What is its average velocity from t = 2 s to t = 4 s?
At t=2, x(2)=-1.76
At t=4, x(4)=14.24
The average velocity is given by,
42/12 = 3.5, 63/18 = 3.5, therefore we will be multiplying the last time by 3.5. 40x3.5= 140, and therefore, the number of pencils produced in 40 seconds is 140
Answer:
By substituting the value of the variable and simplifying it with the equation you get 158.

Answer:
<h2>The answer is - 2</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the slope we must first write the equation in the general equation above
That's
6x + 3y = 15
<u>Make y the subject</u>
Send 6x to the other side of the equation
3y = - 6x + 15
<u>Divide both sides by 3</u>
We have
y = - 2x + 5
Comparing with the general equation above
Slope / m = - 2
Hope this helps you
