A. A parallelogram has a base of 9 units and a corresponding height of ſ units. What is its area? b. A parallelogram has a base of 9 units and an area of 12 square units. What is the
corresponding height for that base?
c. A parallelogram has an area of 7 square units. If the height that corresponds to a base is
unit, what is the base?

1. minimum

2. 6400

3. eight

hope this !

is there a picture

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
