Answer:
(b) tangible approximation of the product that often look and feel like the product
Step-by-step explanation:
"Physical" means it exists as an object in the real world, not just as a model on a computer screen. "Prototype" means it is an approximation of the finished product, lacking in one or more details of appearance, structure, or functionality.
7c² + 8c + 1 = 0
c = <u>-(8) +/- √((8)² - 4(7)(1))</u>
2(7)
c = <u>-8 +/- √(64 - 28)</u>
14
c = <u>-8 +/- √(36)
</u> 14
c = <u>-8 +/- 6</u>
14
c = <u>-8 + 6</u> c = <u>-8 - 6</u>
14 14
c = <u>2</u> c = <u>-14</u>
14 14
c = ¹/₇ c = 1
The solution is equal to { 1, ¹/₇}.

Answer:
Substitute into the quadratic formula
-6 ± √32 / 2
= -3 ± √16
= 1 and -1 are the answer
Answer and Step-by-step explanation:
The mistake is that the sign (<) isn't flipped.
When a negative number is multiplied, the sign of the inequality flips to go the other way, so < would go >.
There are 17,576 combinations.
There are 26 letters to choose from for the first letter; 26 for the second letter; 26 for the third letter; and 1 for the last letter (it must be the same as the first letter). This gives us
26*26*26*1 = 17576
