The descriminant is b^2-4ac so for 26 it would be -5^2 - 4 (1) (7). The quadratic formula is -B plus or minus the square root of b squared minus 4ac over 2a
Answer:
is it asking for linear functions
<h3>Roman numerals</h3>
Numbers are written as combinations of letters.
<h3>Taking into account that:</h3>
- x = 10 ⇒ (It is repeated twice)
- v = 5
- lll = 3 (To form this number, the "I", it can form itself up to 3. From 4 it changes.)
We do a sum of roman numerals
X + X + V + III = XXVIII
10 + 10 + 5 + 3 = 28
The Roman numeral <u>XXVIII</u> corresponds to the number 28 (twenty-eight).

Circumference of circular track, C = 0.5 miles = 0.5×5280 feet = 2640 feet.
We know, circumference in circle is given by :
( Here, r is radius i.e distance of centre from track )
Putting values in above equation :
2 × 3.14 × r = 2640
6.28 × r = 2640
r = 420.38 feet
Therefore, distance between centre and track is 420.38 feet .
Hence, this is the required solution.
