Mel - So this is purely in theory, right? 

If you were my kid, I'd ask you how much the shoes were. I actually ask myself a similar question when I get asked to buy a combo- if I want a burger and drink, they'll ask if I want fries. It would literally cost me like .10 for the fries. I won't eat them but I can give them to a student or something so, sure, I'll get the combo. 

Does that make any kind of sense?

Explain how to make a precise graph of y = -2x + 3 without making a T-Table.
kifflom [539]

Answer:

x 2 + 5 x + 6

Step-by-step explanation:

y = m x + c

y- intercept

x = 0

y = (-2) (0) + 3

=3

(x =0,  y = 3)

<h3>slope -2 </h3><h3>y = -1 x + 3</h3>

The next model of a sports car will cost 4.4% more that the current model. The current model costs $48,000, How much will the pr
podryga [215]

Answer:

$50,112.  Increase is $2,112

Step-by-step explanation:

1st way.  $48,000 x 1.044 = $50,112.  1.044 is the same thing as saying 104.4% of the total price in decimal form, which is what the new price would be when adding 4.4% to the 100% of the original price.  To get the amount of increase just find the difference in the two.  $50,112-$48,000 = $2,112

2nd way.  $48,000 x .044.  =  $2,112 .044 is 4.4% in decimal form. So you found the increase here.  Add the increase to the original price.  $48,000 + $2,112 to get the new price of $50,112.

A mass of 5 kg stretches a spring 10 cm. The mass is acted on by an external force of 10sin( t ) N(newtons) and moves in a mediu
yKpoI14uk [10]

Answer:

A) C1 = 0.00187 m = 0.187 cm,  C2 = 0.0062 m = 0.62 cm

B)  A sample of how the graph looks like is attached below ( periodic sine wave )

C) w = \sqrt[4]{3} is when the amplitude of the forced response is maximum

Step-by-step explanation:

Given data :

mass = 5kg

length of spring = 10 cm = 0.1 m

f(t) = 10sin(t) N

viscous force = 2 N

speed of mass = 4 cm/s = 0.04 m/s

initial velocity = 3 cm/s = 0.03 m/s

Formulating initial value problem

y = viscous force / speed = 2 N / 0.04 m/s = 50 N sec/m

spring constant = mg/ Length of spring = (5 * 9.8) / 0.1 = 490 N/m

f(t) = 10sin(t/2) N

using the initial conditions of u(0) = 0 m and u"(0) = 0.03 m/s to express the equation of motion

the equation of motion = 5u" + 50u' + 490u = 10sin(t/2)

A) finding the solution of the initial value

attached below is the solution and

B) attached is a periodic sine wave replica of how the grapgh of the steady state solution looks like

C attached below
