B1 = 2
b2 = (b1)^2 + 1 = 2^2 + 1 = 5
b3 = (b2)^2 + 1 = 5^2 + 1 = 26

b4 = (b3)^2 + 1 = 26^2 + 1 = 676+1=<span>677</span>

Find the number b such that the line y = b divides the region bounded by the curves x = y^2 − 1 and the y-axis into 2 regions wi

Because of the symmetry, we can just go from x=0 to x=2 to find the area between 
<span>y = x^2 and y = 4 </span>

<span>that area = ∫4-x^2 dx from 0 to 2 </span>
<span>= [4x - (1/3)x^3] from 0 to 2 </span>
<span>= 8 - 8/3 - 0 </span>
<span>= 16/3 </span>

<span>so when y = b </span>
<span>x= √b </span>
<span>and we have the area as </span>
<span>∫(b - x^2) dx from 0 to √b </span>
<span>= [b x - (1/3)x^3] from 0 to √b </span>
<span>= b√b - (1/3)b√b - 0 </span>

<span>(2/3)b√b = 8/3 </span>
<span>b√b =4 </span>
<span>square both sides </span>
<span>b^3 = 16 </span>
<span>b = 16^(1/3) = 2 cuberoot(2) </span>
<span>or appr 2.52</span>

Using the Addition Method, solve for x in the following system of linear equations.
Anna71 [15]

Answer:

x = 0

Step-by-step explanation:

if 2y + x = 4

we can assume that y = 2
if y - 3x = 2

it means 2 - 0 = 2

therefore x = 0

Instructions: Given the following constraints, find the maximum and minimum values for z.
loris [4]

Answer:

x+3y\leq 0        

x-y\geq 0

1) x+3y=0

x-y=0

-----

4y=0

y=0

x=0

(0,0)

2)(x+3y=0)3

3x-7y=16

3x+9y=0

3x-7y=16\\------\\16y=-16

y=-1

(3,-1)

3)(x-y=0)3

3x-7y=16

3x-3y=16

3x-3y=0

3x-7y=16\\------\\4y=-16

y=-4

x=4

(4,-4)

Z=-x+5y

(0,0):z=0

(3,-1):z=-8

(4,-4):z=-24

Maximum \:Value\: of\: z:0

Minimum\: Value\: of\: z:-24
