Una mujer de 5 pies de altura esta de pie cerca de un farol que tiene 12 pies de altura, . Encuentre una función que modele la longitud de su sombra en términos de distancia desde la base del farol. un triangulo isósceles tiene un perímetro de 8cm. Encuentre una función que moldee su área a en términos de la longitud de su base

there is no

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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
