Answer:
Approximately 14.42
Step-by-step explanation:
All you have to do is use the Pythagorean Theorem! In case you don't remember, it's a² + b² = c², where a and b are legs and c is the hypotenuse.
So...
8² + 12² = c²
64 + 144 = c²
208 = c²
= 14.42
Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:
Plug in the values
Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3
Answer:
B. f(x) = 884 •
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo
My answer:
Given that:
- A company opened in 1998 and turned a profit its first year, it means that the company has initial value in its function
- The company's revenues increased annually thereafter => it is an exponental function with the base number is greater than 1
- x represents the number of years in operation => which means x is the domain of the company revenue function
- f(x) represents the company's annual revenue
The following functions could model this situation is:
B. f(x) = 884 • where:
884 is a profit its first year
1.22 growth rate in revenue
x represents the number of years in operation
Hope it will find you well.
