PLEASE HELP<br>1.6x-(x-2.8)=(0.2x+1.5)-0.7<br><br>Solve for x

skelet666 [1.2K]

The answer is

1.6x-(x-2.8)=(0.2x+1.5)-0.7

1.5-0.7

1.6x-(x-2.8)=0.2x+0.8

1.6x-x

0.6x+2.8=0.2x+0.8

2.8-2.8 0.8-2.8

0.6x=0.2x-2

0.6x-0.2x 0.2x-0.2x

0.4x=-2

0.4x/0.4 -2/0.4

X=-5

The number of mosquitoes M(x), in millions, in a certain area depends on the June rainfall x, in inches: M(x) = 13 x - x2. What

My name is Ann [436]

Answer:

The number of mosquitoes is maximum for 6.5 inches rainfall.

Step-by-step explanation:

The given function is

$M(x)=13x-x^2$ .... (1)

where, M(x) is number of mosquitoes in millions and x the June rainfall in inches.

We need to find the rainfall that produces the maximum number of mosquitoes.

Differential the above function with respect to x.

$M'(x)=13-2x$ .... (2)

Equate first derivative equal to 0.

$13-2x=0$

$2x=13$

$x=\frac{13}{2}=6.5$

Differential function (2) with respect to x.

$M''(x)=-2$

Double derivative is negative. So, the value of function is maximum at x=6.5.

Therefore, the number of mosquitoes is maximum for 6.5 inches rainfall.
