Joe is using the function E= 1.89x + 2.89y to minimize his expenses when selling

stepan [7]

Answer:

$(d)\ \$13.34$

Step-by-step explanation:

Given

$E = 1.89x + 2.89y$ -- Objective function

Constraints:

$2x + y > 10$

$x + 2y > 8$

$x,y>0$

Required

Minimum value of E

To do this, we apply graphical method

See attachment for plots of $2x + y > 10$ and $x + 2y > 8$

From the attached plot, the point that satisfy $x,y>0$ is:

$(x,y) = (4,2)$

So, we have:

$E = 1.89x + 2.89y$

This gives:

$E =1.89 * 4 + 2.89 * 2$

$E =7.56 + 5.78$

$E =13.34$

The volume of a sphere can be determined by the formula V = 4/3 πr^3, where r is the radius. What is the volume of a sphere with

allochka39001 [22]

Answer:

$V = \frac{99}{7} x^{9}y^{-6}$

Step-by-step explanation:

Given

$V = \frac{4}{3}\pi r^3$

Required

Find V when

$r = \frac{3}{2}x^3y^{-2$

Substitute $\frac{3}{2}x^3y^{-2$ for r in $V = \frac{4}{3}\pi r^3$

$V = \frac{4}{3}\pi * (\frac{3}{2}x^3y^{-2})^3$

Open bracket

$V = \frac{4}{3}\pi * \frac{3}{2}^3 * x^{3*3}y^{-2*3}$

$V = \frac{4}{3}\pi * \frac{27}{8} * x^{9}y^{-6}$

Simplify the fractions

$V = \pi * \frac{9}{2} * x^{9}y^{-6}$

Let

$\pi = \frac{22}{7}$

So:

$V = \frac{22}{7} * \frac{9}{2} * x^{9}y^{-6}$

$V = \frac{11}{7} * \frac{9}{1} * x^{9}y^{-6}$

$V = \frac{99}{7} * x^{9}y^{-6}$

$V = \frac{99}{7} x^{9}y^{-6}$

A. 5° B. 35° C. 31° D. 7°

MrRissso [65]

Answer:

(2x +30) and (3x -5) (they're opposite to eachother, so they're equal)

2x + 30 = 3x - 5 (set them equal to eachother, then subtract 3x from both side)

-1x = -35 (divide both sides by -1 to isolate x)

x = 35 or B (this is your answer)

Step-by-step explanation:

I hope this helps :))
