6*8^x + 18x + 5 is the answer

Take the f function minus the g function and subtract like terms
4 - (-2) is 6, so that part is 6*8 to the x power,
then you have the 18x with nothing subtracted from it,
and then -7 - -12....or at least that looks like -12...hard to see with it being covered up...anyway that part would be 5.

so 6*8^x + 18x + 5 is the answer

so 3q is 3 times quarters

so 3q+3 would be 3 times plus 3

equation is 3q+3

the value would be 10(3q+3)

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.

To create an entry code, you must first choose 2 letters and then 2 single digit numbers. How many entry codes can you create?

ivann1987 [24]

Answer:

55600

Step-by-step explanation:

First times the number of possibilities of the amount of letters it could be so 26X26 as it is a non consecutive possibility that means both letters have the possibility to be the same. Then take the product of 26X26 and multiply it by the possibilities of the first number which is 10 then repeat that by again multiplying the product by 10 to represent the number of possibilities for the second number
