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
77julia77 [94]
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>

4m≥m+9&gt;-9+4m<br> Please answer urgent
Vsevolod [243]
Next time, please include the instructions.

This inequality could be broken into two parts:

4m\geq m + 9   AND   m + 9 > -9 + 4m

Focus first on the inequality m + 9 > -9 + 4m.  subtract m from both sides, obtaining:

9 > -9 + 3m.  Next, add 9 to both sides, obtaining:  18>3m, or m<6

Last step:  Determine whether the inequality <span>4m≥m+9 is true if m<6.</span>

An aquarium is a cylinder with a diameter of 203 feet and a height of 25 feet. What is the volume of the aquarium
lilavasa [31]

Volume formula for a cylinder is pi*r^2*h

h=height=25 feet

r=radius=101.5

Radius is half of the diameter.

Plug those numbers in: pi*101.5^2*25= 809136.822886= 8.09*10^5 hopefully this helps! ^-^
