A weight attached to a spring is at its lowest point, 9 inches below equilibrium, at time t = 0 seconds. When the weight it rele
a_sh-v [17]
The motion can be modeled as
x(t) =9 \, cos( \frac{2 \pi t}{T} )
where 
x = the position below the equilibrium position
T =  the period of the motion
t = time

The weight returns to its equilibrium position when x = 0. 
This occurs when
\frac{2 \pi t}{T} = \frac{ \pi }{2}
That is,
t= \frac{T}{4}

Because the weight returns to the equilibrium position when t =  3 s, therefore
T = 12 s
The motion is
x(t) = 9 \, cos( \frac{ \pi t}{6} )

When t = 1 s, the position of the weight from equilibrium is
d = 9 \, cos( \frac{ \pi }{6} ) = 9( \frac{1}{2} ) = 4.5 \, in

Answer:
d = 9 \, cos( \frac{ \pi }{6} ) = 4.5 \, in

Dilation is either : enlargement or shirking.

Simply you multiply the ordered pair times the dilation vector (Origin-Centered) 

D.F = dilation factor;


d.f  = 5

C' = d.fC

when you multiply a constant times an ordered pair , it multiples into each of the pair.


C' = 5 ( -5 , 1 ) = ( -25, 5 ) 

In case you were asked for A' , B' (test yourself before checking) 



A' = 5 (-4,3) = ( -20 , 15)

B' = 5 ( 2, 3 ) = ( 10, 15) 

Dividing the dilated by the original pair results in the dilation factor

A'/A =  (-20/15)/(-4,3) = 5(-4,3)/(-4,3) = 5

Gre4nikov [31]
The right answer for the question that is being asked and shown above is that: "D.) There is likely an association between the categorical variables because the relative frequencies are both close to 0.50." Given that a relative frequencies of 0.48 and 0.52, there will be an association between the categorical variables.<span>

When two 6-sided dice are rolled, there are 36 possible outcomes. Find the probability that the sum is 8
katrin2010 [14]

Answer:

5/36

Step-by-step explanation:

Probability is the outcome that a  event will occur

Probability = Expected outcome/Total outcome

Since two sided dice are rolled, the total outcome will be expressed as;

Total outcome = 36

Since we are to find the probability that the sum is 8, the values that gives a sum of 8a re;

(2,6)(6,2), (5, 3), (3,5), (4, 4)

The expected outcome = 5

Probability = 5/36

Hence the probability that the sum is 8 is 5/36
