Someone please answer this. Please give answer in form of square root.

A cable installer charges $40.00 per hour plus a $60.00 service charge. Your father's firm hires him to hook up his company's in

Vadim26 [7]

Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)

60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges

A mass oscillating up and down on the bottom of a spring (assuming perfect elasticity and no friction or air resistance) can be

alexdok [17]

The motion of the mass as it moves on the bottom of the spring is a

repetitive motion.

$\mathrm{The \ motion \ of \ the \ mass \ attached \ to \ the \ spring \ is \ }\displaystyle d = 6 \cdot sin\left(\frac{\pi}{2} \cdot t \right)$

Reasons:

The general form of the equation of the simple harmonic motion of the

mass is <em>d</em> = a·sin(ω·t)

Where;

d = The distance of the mass from the rest position

a = The maximum displacement of the mass from the equilibrium position = 6 cm

ω = The frequency of rotation

t = The time of motion

ω = The frequency of rotation

$\displaystyle \omega = \mathbf{\frac{2 \cdot \pi}{T}}$

Where;

T = The time to complete one cycle (the period of oscillation) = 4 seconds

$\displaystyle \omega = \frac{2 \cdot \pi}{4} = \frac{\pi}{2}$

Combining the above values gives the modelling equation as follows;

$\displaystyle d = 6 \cdot sin\left(\frac{\pi}{2} \cdot t \right)$
