When you dive below the surface of the water, the pressure increases. You can feel this in your ears when you dive to the bottom of a deep swimming pool or spring. The function that describes this relationship is P(d)=14.5+2966d , where d is the depth in feet below the surface of the water and P is the pressure in pounds per square inch (PSI).

so, converting firstly the mixed fractions to improper fractions and then "adding".

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

look at the picture i have filled out a table for it. hope this .
