You use an activity book to solve a puzzle. the book directs you to specific pages within it. the puzzle’s start page directs you to page 20. on page 20, you are given one of the alphabets of the answer, and the page number indicating the next page and letter. you continue flipping to each page until you have all the letters that form the answer. finally, you arrange these letters to form a meaningful word. what kind of challenge has been described here? resource management spatial awareness pattern recognition and matching reaction time

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

answer: 5

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
