Product #1: itech device the current resale value is $300. the resale value is expected to decrease by 30% per year for the next several years. product #2: dynasystems device the current resale value is $300. the resale value is expected to decrease $45 per year for the next several years. define formulas to model the expected resale value, v, in dollars for each device as functions of the number of years from now, x.

Net resale value after x years for product #1 is $300 - $90x

Net resale value after x years for product #2 is $300 - $45x

Step-by-step explanation:

Resale value of product 1 = $300

Decrease in resale value = 30% per year

Thus,

Net resale value after x years will be = Initial Resale value - x( 30% of $300 )

or

= $300 - x( 0.3 × $300 )

= $300 - $90x

Hence,

Net resale value after x years for product #1 is $300 - $90x

Resale value of product 2 = $300

Decrease in resale value = $45 per year

Thus,

Net resale value after x years will be = Initial Resale value - $45x

or

= $300 - $45x

Hence,

Net resale value after x years for product #2 is $300 - $45x

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
