Answer:

The displacement equation for this periodic motion is given as

y = (0.345 Sin πt) m

y = (0.345 Sin 3.142t) m

Step-by-step explanation:

The displacement equation for periodic motion is given as

y = A sin wt

A = amplitude of the motion, that is, the maximum displacement from the equilibrium position = 0.345 m

w = angular frequency = (2π/T)

T = period of the periodic motion = 2.00 s

w = (2π/T) = (2π/2) = π rad/s

t = time of motion, measured in seconds.

y = (0.345 Sin πt) m

y = (0.345 Sin 3.142t) m

Hope this Helps!!!

X-5y=2 and 9x+8=15 solve by substitution

lozanna [386]

$x-5y=2$
Hence $x=2+5y$ (Equation I)
$9x+8=15$ (Equation II)
Substituting Equation I in Equation II
$9(2+5y)+8=15$
$18+45y+8=15$
$26+45y=15$
$45y=-11$
Hence $y= - \frac{11}{45}$

Substituting this in Equation in I to get X

$x-5(- \frac{11}{45} )=2$
$x+ \frac{11}{9}=2$
$x= 2- \frac{11}{9}$
$x= \frac{17}{9}$

Maria scored 72, 97, and 82 on her first three math tests. She wants to have a mean score of 82 for the quarter. How many points

Rom4ik [11]

Answer:

She needs 77 on her last test to earn an 82 for the quarter.

Step-by-step explanation:

Maria scored 72, 97, and 82 on her first three math tests.

She wants to have a mean score of 82 for the quarter.

Let us assume that she must score x on her last test to earn an 82 for the quarter.

So the average score will be,

$=\dfrac{72+97+82+x}{4}$
