Oooh! I love this kind of math, so easy to do!

Like I say ALL the time, if you know how to solve percentages you know how to solve anything that deals with percentages. If you don't izz all gucci! :D

To solve a percentage make it a decimal & multiply. :) (SIMPLE)
- .300 % multiplied by 1000 = 300 :D you would pay 300$ a year obviously!

I'm not that great at percentage math, although it is fairly easy. I hope you can use this information too push you closer too the answer! Good Luck! <3

The position of an object moving along an x axis is given by x = 3.24 t - 4.20 t2 + 1.07 t3, where x is in meters and t in secon

Pavel [41]

Answer and explanation:

Given : The position of an object moving along an x axis is given by $x=3.24t-4.20t^2+1.07t^3$ 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

$x(t)=3.24t-4.20t^2+1.07t^3$

$x(1)=3.24(1)-4.20(1)^2+1.07(1)^3$

$x(1)=3.24-4.20+1.07$

$x(1)=0.11$

b) At t= 2 s

$x(t)=3.24t-4.20t^2+1.07t^3$

$x(2)=3.24(2)-4.20(2)^2+1.07(2)^3$

$x(2)=6.48-16.8+8.56$

$x(2)=-1.76$

c) At t= 3 s

$x(t)=3.24t-4.20t^2+1.07t^3$

$x(3)=3.24(3)-4.20(3)^2+1.07(3)^3$

$x(3)=9.72-37.8+28.89$

$x(3)=0.81$

d) At t= 4 s

$x(t)=3.24t-4.20t^2+1.07t^3$

$x(4)=3.24(4)-4.20(4)^2+1.07(4)^3$

$x(4)=12.96-67.2+68.48$

$x(4)=14.24$

(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,

$\triangle x=x(4)-x(0)$

$\triangle x=14.24-0$

$\triangle x=14.24$

(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,

$\triangle x=x(4)-x(2)$

$\triangle x=14.24-(-1.76)$

$\triangle x=14.24+1.76$

$\triangle x=16$

Since the domain are the x-values of the function, we need to find the y-values using those x-values.
- for x= $\frac{1}{2}$ , $log x_{2} ( \frac{1}{2} )=-1$ . Now we have our first ordered pair: $( \frac{1}{2} ,-1)$
- for $x=1$ , $log_{2} (1)=0$ which gives us our next ordered pair: $(1,0)$
- for x=2, $log_{2} (2)=1$ , so (2,1)
- for x=4, $log_{2} (4)=2$ , so (4,2)
- for x=8, $log_{2} (8)=3$ , so our last order pair is (8,3)

Finally we can plug the points and joint them to create our graph:
