The average monthly forecast (that can also be referred to as non-seasonal, exponentially smoothed, or rolling moving average forecast) at the start of November (FNov ) is 700 units. Alpha ( ) equals 0.15 Seasonality factors: Oct. 0.80 (SFAC) Nov. 0.70 Dec. 1.20 Jan. 1.50 Feb. 1.10 Use the spaces between the questions to calculate your answers.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.

the correct answer is

jeremy can row 1.333 miles per hour.
