Answer:

the quotient would be around 90 if you are estimating. If you are looking for exact the answer would be 92.

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s

serg [7]

solution:

s( t ) = ( 2 )sin( πt ) + ( 2 )cos(πt )

v( t ) = s'( t ) = ( 2π )cos( πt) - ( 2π )sin( πt )

vavg = 1 / ( b - a ) Integral a to b [ v( t ) ] dt

( a )

vavg

= 1 / ( 2 - 1 ) Integral 1 to 2 [ ( 2π)cos( πt ) - ( 2π )sin( πt ) ] dt

= [ ( 2)sin( πt ) + ( 2 )cos( πt ) ] 1to 2

= [ ( 2)sin( 2π ) + ( 2 )cos( 2π ) ] - [ ( 2 )sin( π ) + ( 2 )cos( π) ]

= 4 cm / s

( b )

vavg

= 1 / ( 1.1 - 1 ) Integral 1 to 1.1 [ ( 2π)cos( πt ) - ( 2π )sin( πt ) ] dt

= 10 [ ( 2 )sin( πt ) + ( 2 )cos( πt ) ] 1 to 1.1

= 10 [ [ ( 2 )sin( 1.1π ) + ( 2)cos( 1.1π ) ] - [ ( 2 )sin( π) + ( 2 )cos( π ) ] ]

-5.20 cm /s

( c )

vavg

= 1 / ( 1.01 - 1 ) Integral 1 to 1.01 [ ( 2π)cos( πt ) - ( 2π )sin( πt ) ] dt

= 100 [ ( 2 )sin( πt ) + ( 2 )cos( πt ) ] 1 to 1.01

= 100 [ [ ( 2 )sin( 1.01π ) + (2 )cos( 1.01π ) ] - [ ( 2 )sin( π) + ( 2 )cos( π ) ] ]

-6.18 cm /s

( d )

vavg

= 1 / (1.001 - 1 ) Integral 1 to 1.001 [ ( 2π )cos( πt ) - ( 2π )sin(πt ) ] dt

= 1000 [ ( 2 )sin( πt ) + ( 2 )cos( πt ) ] 1 to 1.001

= 1000 [ [ ( 2 )sin( 1.001π ) + (2 )cos( 1.001π ) ] - [ ( 2 )sin(π ) + ( 2 )cos( π ) ] ]

-6.27 cm /s

The length of a building is 720 inches. use dimensional analysis to convert this quantity to yards

Inessa [10]

1 yard = 36 inches

so 720 inches = 720/36 = 20 yards.

I have no idea how to do this stuff.

Answer: $y=2x^{2}-5x+7$

Step-by-step explanation:

The quadratic equation in its standard form is:

$y=ax^{2}+bx+c$

Now, we are given 5 points of the parabola (if you graph a quadratic equation you will have a parabola), however we only need to choose three points to find the coeficients $a$ , $b$ and $c$ in the quadratic equation.

So, let's choose the first three points:

(-1,14):

$14=a(-1)^{2}+b(-1)+c$

$14=a-b+c$ (1)

(0,7):

$7=a(0)^{2}+b(0)+c$

$7=c$ (2)

(1,4):

$y=2x^{2}-5x+7$

$4=a(1)^{2}+b(1)+c$

$4=a+b+c$ (3)

Substituting (2) in (1) and (3):

$14=a-b+7$ (4)

$4=a+b+7$ (5)

At this point we have a system with two equations.

Adding (4) to (5):

$18=2a+14$ (6)

Isolating $a$ :

$a=2$ (7)

Substituitng (7) in (3):

$4=2+b+7$ (8)

Isolating $b$ :

$b=-5$ (9)

Now we have the three coeficients and we can write the quadratic equation:

$y=2x^{2}-5x+7$

The sum of 55+66 as the product of their gcf and another sum

marusya05 [52]

$55+66=121 \\\\ 55|5 \\11|11 \\1 \\\\ 55=5*11 \\\\ 66|6\\11|11\\1 \\\\66=6*11 \\\\ G.C.F(55;66)=11 \\\\ 11*x=121 \\\\ x=3+8 \\\\ \boxed{11*(3+8)=121}$
