Find the number b such that the line y = b divides the region bounded by the curves y = 36x2 and y = 25 into two regions with eq
Gemiola [76]

Answer:

b = 15.75

Step-by-step explanation:

Lets find the interception points of the curves

36 x² = 25

x² = 25/36 = 0.69444

|x| = √(25/36) = 5/6

thus the interception points are 5/6 and -5/6. By evaluating in 0, we can conclude that the curve y=25 is above the other curve and b should be between 0 and 25 (note that 0 is the smallest value of 36 x²).

The area of the bounded region is given by the integral

\int\limits^{5/6}_{-5/6} {(25-36 \, x^2)} \, dx = (25x - 12 \, x^3)\, |_{x=-5/6}^{x=5/6} = 25*5/6 - 12*(5/6)^3 - (25*(-5/6) - 12*(-5/6)^3) = 250/9

The whole region has an area of 250/9. We need b such as the area of the region below the curve y =b and above y=36x^2 is 125/9. The region would be bounded by the points z and -z, for certain z (this is for the symmetry). Also for the symmetry, this region can be splitted into 2 regions with equal area: between -z and 0, and between 0 and z. The area between 0 and z should be 125/18. Note that 36 z² = b, then z = √b/6.

125/18 = \int\limits^{\sqrt{b}/6}_0 {(b - 36 \, x^2)} \, dx = (bx - 12 \, x^3)\, |_{x = 0}^{x=\sqrt{b}/6} = b^{1.5}/6 - b^{1.5}/18 = b^{1.5}/9

125/18 = b^{1.5}/9

b = (62.5²)^{1/3} = 15.75

Evaluate (2-3)^(4) - 9 = 3.<br> 0-7<br> 0-2<br> 0 1<br> 02
EleoNora [17]

Answer:

Step-by-step explanation:

(2-3)⁴ *4 - 9 + 3 = (-1)⁴ *4 - 9 + 3

                          = 1*4 - 9 +3

                          = 4 - 9 + 3

                          = - 5 + 3

                           = - 2

solve the system of equations y = 5x + 32 y = -4x - 22 a. ( 6, 2) c. ( -6, 2) b. ( -6, -2) d. No solution
earnstyle [38]

Answer:

A) y = 5x + 32

B) y = -4x -22

We multiply B) by -1

B) -y = 4x + 22 then we add it to A)

A) y = 5x + 32

9x + 54 = 0

x = -6

Substituting x = -6 into A) we get

A) y = 5*-6 +32

y = 2

Answer is c. (-6, 2)
