Let a, ß be the roots of x² + 2ax + b =0.......[1]
⇒a + ß = -2a and aß = b
By hypothesis
la-ß | ≤ 2m
⇒ (a-ß)² ≤ 4m²
⇒ (a+ß)²-4aß < 4m²
⇒ 4a²-4b ≤ 4m²
⇒a² - b ≤ m²......(2)
And discriminant of (1) is >0
⇒4a²-4b> 0
⇒ b <a²...... (3)
From (2) and (3)
a² > b≥ (a² - m²)
b = [a² - m², a²)
Question 1. is C
question 2. is <span>There is not enough information to prove that the triangles are congruent. The </span>ongruence statement can you write about the triangles in the previous problem is <span>△JFE≅△SFV
question 3. i think itd be D</span>
Reserved seats -
20,000 multiplied by $17.50 is $350,000
General seats -
25,000 multiplied by 10.75 is $268,750
$268,750 added with $350,000 is $618,750.
The total amount of money would be $618,750.
Hope this helps!
Answer:
1. - completed
2. expanded = a · a · a · a
3. base = a | exponent = 5 | expanded = a · a · a · a · a
4. - completed
5. base = c | exponent = 3 | expanded = c · c · c
6. base = c | exponent = 4 | expanded = c · c · c · c
7. base = m | exponent = 2 | expanded = m · m
8. base = m | exponent = 3 | expanded = m · m · m
9. power = y⁵ | base = y | exponent = 5
10. power = y⁸ | expanded = y · y · y · y · y · y · y · y
hope this helps ! brainliest ?
