Answer:
-8/5, 13/5
Step-by-step explanation:
Use the process of elimination to find out the y and plug the y in to get the x.
Answer:
7/8 1/8 + 6/8 1/8 + 3/4 1/8 + 1/4 + 2/4 1/8 + 1/4 + 1/2. Like that?
Step-by-step explanation:
Answer:
Real Zeros x = ±4
Complex zeros : x = ±3 i
Step-by-step explanation:
<u><em>Explanation</em></u>
f(x) = x⁴ + 5x² – 36
f(x) = x⁴ + 5x² – 36
= (x²)² + 9 x² - 4 x² - 36
= x² (x² + 9) - 4( x² +9)
= (x² -4 ) (x² +9)
f(x) = x⁴ + 5x² – 36 = (x² -4 ) (x² +9)
(x² -4 ) (x² +9) = 0
⇒ x² -4 = 0 and x² +9 =0
⇒ x² -2² = 0 and x² = -9
⇒ x = ±4 and x = ±3 i
Real Zeros x = ±4
Complex zeros : x = ±3 i
S = a0 / (1 - r)
S is the sum
a0 is the first term
r is the ration
The sum is 2, and the first term is 0.5, so plug in what you know and see what you come up with:
2 = 0.5 / (1 - r)
That's an equation you can solve:
2(1 - r) = 0.5
1 - r = 0.5 / 2 = 0.25
0.75 - r = 0
0.75 = r
Ratio is 0.75.
