Answer:

$FG = 7$

Step-by-step explanation:

Given

$EG = 5x + 7$

$EF = 5x$

$FG = 2x - 7$

Required

Determine the length of FG

Since, F is on segment EG, then

$EG= EF + FG$

Substitute values for EG, EF and FG

$5x + 7 = 5x + 2x - 7$

Collect Like Terms

$5x - 5x - 2x = -7 - 7$

$- 2x = -14$

Solve for x

$x = -14/-2$

$x = 7$

Substitute 7 for x in $FG = 2x - 7$

$FG = 2 * 7- 7$

$FG = 14- 7$

$FG = 7$

Chance of u choosing meat is 5/15
first friend chooses, probability is 4/14
second friend chooses, probability is 3/13
so multiplying all 3 probablilities we get 2.2 percent

Find the area of the part of the plane 5x + 4y + z = 20 that lies in the first octant.

BlackZzzverrR [31]

This part of the plane is a triangle. Call it $\mathcal S$ . We can find the intercepts by setting two variables to 0 simultaneously; we'd find, for instance, that $y=z=0$ means $5x=20\implies x=4$ , so that (4, 0, 0) is one vertex of the triangle. Similarly, we'd find that (0, 5, 0) and (0, 0, 20) are the other two vertices.

Next, we can parameterize the surface by

$\mathbf s(u,v)=\langle4(1-u)(1-v),5u(1-v),20v\rangle$

so that the surface element is

$\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|=20\sqrt{42}(1-v)\,\mathrm du\,\mathrm dv$

Then the area of $\mathcal S$ is given by the surface integral

$\displaystyle\iint_{\mathcal S}\mathrm dS=20\sqrt{42}\int_{u=0}^{u=1}\int_{v=0}^{v=1}(1-v)\,\mathrm dv\,\mathrm du$
$\displaystyle=20\sqrt{42}\int_{v=0}^{v=1}(1-v)\,\mathrm dv=10\sqrt{42}\approx64.8074$

Mr. James has cylindrical beakers that measure 4 inches in diameter and are 9 inches high. What is the volume contained within t

kirill115 [55]

The equation to find the volume of a cylinder is V = pi•r^2•h.
The radius is half of the diameter. Since Mr. James' beakers have a diameter of 4, their radius would be 2. 2 squared is 4.
Their height is 9 inches.
V = 3.14•4•9
V = 3.14•36
V = 113.04
The answer is C, or 113.04 cubic inches.
