Step-by-step explanation:
(5-\/5)²
25-10\/5+5
30-10\/5
Here, a=30 and b=-10
Answer:
<em>D = 41</em>
Step-by-step explanation:
y = ax² + bx + c
The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.
If D > 0 , then quadratic equation has two distinct real roots.
~~~~~~~~~~~~
x² + 5x - 4
a = 1, b = 5, c = - 4
<em>D </em>= 5² - 4(1)(- 4) = 25 + 16 =<em> 41</em>
Step-by-step explanation:
for getting to next term you multiple 4, so it's an exponential sequence
a×r^n-1
1×4^n-1
sequence: 4^n-1
12th term: 4^12-1
=4^11
=4194304
hope it helps!!
