Answer:
$972.8
Step-by-step explanation:
$12.80 x 76 = $972.8
From your earlier questions, we found
so the wave has amplitude √29. The weight's maximum negative position from equilibrium is then -√29, so you are solving for <em>t</em> in the given interval for which
Divide both sides by √29:
Take the inverse sine of both sides, noting that we get two possible solution sets because we have
and the sine wave has period 2π, so .
OR
where <em>n</em> is any integer.
Now solve for <em>t</em> :
OR
We get solutions between 0 and 0.5 when <em>n</em> = 0 of <em>t </em>≈ 0.196946 and <em>t</em> ≈ 0.363613.
Answer:
x = 2 ±sqrt( 97)
Step-by-step explanation:
log10(x^2 -4x+7) =2
Raise each side to the base 10
10 ^ log10(x^2 -4x+7) =10^2
x^2 -4x +7 = 100
Subtract 7 from each side
x^2 -4x+7-7 = 100-7
x^2 -4x = 93
Complete the square
-4/2 = -2 (-2)^2 = 4
Add 4 to each side
x^2 -4x+4 = 93+4
(x-2)^2 = 97
Take the square root of each side
sqrt((x-2)^2 )=±sqrt( 97)
x-2 = ±sqrt( 97)
Add 2 to each side
x = 2 ±sqrt( 97)
