The temperature y (in degrees Fahrenheit) after t months can be modeled by the function y=−2t2+12t +48, where 1≤t≤12. a. Write the function in vertex form. y= b. Find the maximum temperature during the year. The maximum temperature is degrees Fahrenheit.

where are the options?

step-by-step explanation:

ab: 2 n83b8eb7ebi. 8e yen in

dude thats to long figure it

step-by-step explanation:

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
