Translate each equation into slope-intercept form. Then, state the slope and y-intercept . 4y=2x+20

likoan [24]

Answer:

The slope-intercept form of the equation: y = 0.5x + 5

The slope: m = 0.5

The y-intercept: b = 5

Step-by-step explanation:

Slope-intercept form is y = mx + b, where m is the slope and b is y-intecept

4y = 2x + 20 {divide both sides by 4}

y = 0.5x + 5 ⇒ m = 0.5 and b = 5

Marci needs to rent a storage unit. She needs to determine the volume of the storage unit to decide if the storage unit is big e

stealth61 [152]

Answer:

$Volume = 176ft^3$

Step-by-step explanation:

Given

$Height = 8$

See attachment for base dimension

Required

Determine the volume of the storage unit

From the attachment, we can split the base dimension into two rectangles.

CDEF and ABCG

And the dimensions are:

CDEF

$EF = CD = BD - BC = 5 - 2 = 3$

$ED = FC = FG +AB = 4 + 2 =6$

So, the area of CDEF is:

$Area = EF * ED$

$Area = 3 * 6$

$Area = 18$

ABCG

$AB= GC = 2$

$AG = BC = 2$

$Area = AB * AG$

$Area = 2 * 2$

$Area = 4$

So, the base area is:

$Base\ Area = 18 + 4$

$Base\ Area = 22$

The volume is then calculated as:

$Volume = Base\ Area * Height$

$Volume = 22 * 8$

$Volume = 176$

Find the general solution of the given higher-order differential equation. d3u dt3 + d2u dt2 − 2u = 0

STALIN [3.7K]

$\dfrac{\mathrm d^3u}{\mathrm dt^3}+\dfrac{\mathrm d^2u}{\mathrm dt^2}-2u=0$

This ODE has characteristic equation

$r^3+r^2-2=(r^3-r)+(r^2+r-2)=r(r^2-1)+(r+2)(r-1)$

$=(r(r+1)+(r+2))(r-1)=(r^2+2r+2)(r-1)=0$

which has roots at $r=1,-1\pm i$ . Then the characteristic solution to the ODE is

$u(t)=C_1e^t+C_2e^{(-1+i)t}+C_3e^{(-1-i)t}$

$\implies\boxed{u(t)=C_1e^t+C_2e^{-t}\cos t+C_3e^{-t}\sin t}$
