The
10. a jet flies at an altitude of 52,800 feet.
what is the height of the jet in miles?

The Answer is 10 Miles.

Step-by-step explanation:

The jet is 52,800 feet high.

There are 5,280 feet in a mile.

Divide 52,800 by 5280 to find miles:

52800 / 5280 = 10 Miles.

Hope this Helps!  Have an Awesome Day!! :-)

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
