Answer:

Step-by-step explanation:

It can have at most 1 sensible answer. It may have zero and infinitely many

3x + 6 = - 1 - 3 + 4x Combine the right

3x + 6 = - 4 + 4x Add 4 to both sides

3x + 6 + 4 = 4x Subtract 3x from both sides

3x + 10 -3x = 4x - 3x Combine

10 = x

The only answer (1) that is possible is 10.

A pigpen is to be enclosed using 640 m of fencing along three of its sides, the fourth side being a barn. Determine the dimensio

Basile [38]

Answer:

$W_{max}=480m\\ L_{max}=160m$

Step-by-step explanation:

Since we know we only have 640 feet of fence available, we know that L + W + L = 640, $\implies$ 2L + W = 640. This allows us to represent the width, W, in terms of L: W = 640 – 2L

Remember, the area of a rectangle is equal to the product of its width and length, therefore,

$A_{\rm pigpen}=L(640-2L)\implies 640L-2L^2$

Notice that, quadratic has been vertically reflected, since the coefficient on the squared term is negative, so the graph will open downwards, and the vertex will be a maximum value for the area.

recall,

$x_{max}=-b/2a$
$f(x)_{max}=f(x_{max})$

Since our function is A(L)=640L-2L², we get

a=-2
b=640

plug in the value of a and b into the first formula:

$L_{max}=-(640)/2(-2)\implies 160$

$A(L)_{max}=640(160)-2(160)^2\implies 76800$

hence,the dimensions of the pen that will maximize the area are L=160m and W=76800/160=480m

and we're done!

If the frequency of hba homozygotes is 0.1 what is the value of p2

Angelina_Jolie [31]

we know that

p^2 is the the frequency of hba homozygote

we are given

frequency of hba homozygotes is 0.1

so,

p^2 =frequency of hba homozygotes

we can plug values

and we get

$p^2=0.1$ ..............Answer
