When given points (1,1) and (2,2), what is the slope ?
scoray [572]

Answer:

m=1

Step-by-step explanation:

Slope can be calculated using following formula

m=\frac{y_2-y_1}{x_2-x_1}  ----------- (1)

<u>Here</u>

(x_1, y_1)=(1, 1) \ \ and \ \ (x_2, y_2) = (2, 2)

Substitute values in equation (1)

m=\frac{2-1}{2-1}

m=1

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.
