Answer:
The equation would be B) y = 5x + 17
Step-by-step explanation:
To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -1/5. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 5.
Now that we have this, we can use the point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 7 = 5(x + 2)
y - 7 = 5x + 10
y = 5x + 17
Answer:
Step-by-step explanation:
Given that:
mass m = 100 g = 0.1 kg
Length of the spring = 5 cm = 0.05 m
The set in motion from the equilibrium position u(0) = 0
The set in motion from its equilibrium position with a downward velocity u'(0) = 50 cm/s = 0.5 m/s
The spring constant (k) =
The equation of the system is expressed as:
By estimating the characteristics equation, we have r = ± 14
Thus; the general solution is:
By applying the initial condition:
u(0) = 0
⇒ 0 =
∴
u'(0) = 0.5
0.5 = 14 × c₂
c₂ = 0.5/14
c₂ = 1/28
∴
Equating u(t) = 0, we have t = π/14sec as the time when the mass first returns to its equilibrium position.
Brand b is 2 cents cheaper than brand a because it is 14 cents per ounce and brand a is 16 cents per ounce you do 1.68 divided by 12 and 1.28 divided by 8
Answer:
H
Step-by-step explanation:
Answer:
6 i don't know what the unit is, but its 6 for time
Step-by-step explanation:
It is a two step problem
54=9t
divide both sides by 9 to get the value of t
6=t
I hope that helps you :)
