Answer:
0 real roots
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then the roots are not real
- 9x² + x - 7 = 0 ← is in standard form
with a = - 9, b = 1, c = - 7 , then
b² - 4ac = 1² - (4 × - 9 × - 7) = 1 - 252 = - 251
Since b² - 4ac < 0 then the equation has no real roots
Based off of the first digit in a two-number value like 50 means there's 5 tens.
Answer:
have a picture of something
Answer:
18.85 feet
Step-by-step explanation:
C = 2 x 3.14 x 6/2
The range is 8 and if you needed help finding the median it is 2 I think
Btw remember that median means middle, range means the difference between the highest and lowest number, the mode means what number have the most, and the mean is the total of all the values and then divide by the number of values :)
