Solve the problems below. Please answer with completely simplified exact value(s) or expression(s).
In AABC, AC = BC, CD 1 AB with D E AB, AB = 4 in., and CD = V3 in.
D E
.
Find AC.

the answer will be b x² +x-1

step-by-step explanation:

answer. d.289 hope that

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
