2(x + a) = 4b
2x + 2a = 4b

Answer:

a = 2b - x

Step-by-step explanation:

2(x + a) = 4b \\ 2x + 2a = 4b \\ 2a = 4b - 2x \\  \frac{2a}{2}  =  \frac{4b - 2x}{2}  \\ a =  \frac{2(2b - x)}{2}  \\ a = 2b - x

In a circle of radius 60 inches, a central angle of 35 degrees will intersect the circle forming an arc of length
kow [346]

Convert 35 degrees to radians


35 * pi/180 = 7pi/36


s = r(theta) s is arc length, r is radius, theta is the central angle.


s = 60* 7pi/36


s = 35pi/3 inches ~ 36.65 inches

At the market, 6 batteries cost $10.38. How much do 8 batteries cost?
Dominik [7]
To get the answer you should solve the following equation:
\frac{6}{8}=\frac{10.38}{x}
\frac{3}{4}=\frac{10.38}{x}
x=\frac{4*10.38}{3}=\frac{41.52}{3}=13.84

So, the 8 batteries cost $13.84.

Find the complete time-domain solution y(t) for the rational algebraic output transform Y(s):_________
bija089 [108]

Answer:

y(t)= 11/3 e^(-t) - 5/2 e^(-2t) -1/6 e^(-4t)

Step-by-step explanation:

Y(s)=\frac{s+3}{(s^2+3s+2)(s+4)} + \frac{s+3}{s^2+3s+2} +\frac{1}{s^2+3s+2}

We know that s^2+3s+2=(s+1)(s+2), so we have

Y(s)=\frac{s+3+(s+3)(s+4)+s+4}{(s+1)(s+2)(s+4)}

By using the method of partial fraction we have:

Y(s)=\frac{11}{3(s+1)} - \frac{5}{2(s+2)} -\frac{1}{6(s+4)}

Now we have:

y(t)=L^{-1}[Y(s)](t)

Using linearity of inverse transform we get:

y(t)=L^{-1}[\frac{11}{3(s+1)}](t) -L^{-1}[\frac{5}{2(s+2)}](t) -L^{-1}[\frac{1}{6(s+4)}](t)

Using the inverse transforms

L^{-1}[c\frac{1}{s-a}]=ce^{at}

we have:

y(t)=11/3 e^{-t} - 5/2 e^{-2t} -1/6 e^(-4t)

40% of the seats in a packet produce flowers. The rest produce pink flowers. Youth table of random digits on pp. A-3 to A-4 in t
saw5 [17]
If there are 40% of the seats in a packet that produce flowers and the rest produces pink flowers, then there are 35% seats for white flowers planted. The genes that are passed down from the parents are being shared by the offspring. It can be shown if the trait is recessive or dominant from the parents’ gene.
