A frame shop charges according to both the amount of framing needed to surround the picture and the amount of glass needed to cover the picture. a. Find the area and perimeter of the trapezoid-shaped framed picture to the right.
b. Identify whether the frame has to do with perimeter or area and the same with the glass.
a. The area of the picture is sq in and the perimeter is in

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

-4, -2, 1, 4

step-by-step explanation:
