In the diagram above, zero represents the location of Martin Luther King Middle School. The point represents the library, which is located to the east of the middle school. In other words, create a real-world situation that could represent point -2/3, and describe its location in relation to 0 and point.

Is 3/5 equivalent to 6/8

Answers

no because 3*2= 6 while 5*2=10 so if it was equivalent it would of been 3/5 to 6/10

It is not equivalent because if you see,you will have to multiply first and see if the relate.3x2=6,and 5x2=10.It will not work so it will be 3/5 is equivalent to 6/10

A point on a damped spring has motion given by s(t)=2e^(-1.5t) s in(2(pi)t), where s is measured in centimeters and t is measured in seconds. Choose which of these is the graph for the velocity function for 0 < or equal to t < or equal to 4

error percentage is 0.6%

Graph-C

Step-by-step explanation:

(7)

we are given cube

Let's assume edge of cube =x

so, volume of cube will be

$V(x)=x^3$

we are given

V=125000

so, we can find 'x'

$125000=x^3$

$x=50$

So,

$a=50$

now, we can use linear approximation formula

$L(x)=V(a)+(x-a)V'(a)$

$L(x)=V(a)+(\Delta x)V'(a)$

we have

$\Delta x=0.1$

we can plug a=50

$L(x)=V(50)+(0.1)V'(50)$

$V(x)=x^3$

we can find derivative

$V'(x)=3x^2$

now, we can plug x=50

$V'(50)=3(50)^2$

$V'(50)=7500$

now, we can plug these values

and we get

$L(x)=V(50)+(0.1)* 7500$

$L(x)=V(50)+750$

$L(x)-V(50)=750$

so, error is

$error=750$

now, we can find percentage error

Percentage is

$=(750)/(125000)* 100$

=0.6%

so, error percentage is 0.6%

(8)

we are given

$s(t)=2e^(-1.5t)sin(2\pi t)$

We will find derivative

To get velocity , we will find derivative

$s'(t)=(d)/(dt)\left(2e^(-1.5t)\sin \left(2\pi t\right)\right)$

we can use product rule

and we get

$s'(t)=-3e^(-1.5t)sin(2\pi t)+4\pi e^(-1.5t) sin(2\pi t)$

so, we get velocity equation as

$v(t)=-3e^(-1.5t)sin(2\pi t)+4\pi e^(-1.5t) sin(2\pi t)$

now, we can draw graph

we can see that firstly , we get maxima and then minima

so, our graph would be

Two equations are given below: a − 3b = 9 a = b − 3 What is the solution to the set of equations in the form (a, b)? (−9, −6) (−4, −3) (−6, −3) (−9, −7)

Answers

To solve this equation you can plug in these numbers into the equations, so for example you can that the equation a-3b=9 and the points are (-9,-6). you would then insert the numbers so you would have the equation (-9)-3(-6)=9. simplify -9+18=9 and there you have it, the answer is (-9,-6)
