It would be 4 hours because that's the closet you can get with the answer
To have 2 real number solutions the discriminant b^2 - 4ac must be greater than zero.
so the condition for 2 real roots in this equation is:-
b^2 - 4*1*5 > 0
b^2 > 20
b > sqrt 20 ( positive root) Answer
Answer:
y=27.8
Step-by-step explanation:
- 8^2=17^2+16^2-2(16)(17)cosY
- 8^2-17^2-16^2/-2(17)(16)=cosY
- -481/-544=cosY
- 0.8842=cosY
- Y is about 27.8
-5n-8(1+7n)=8
Let's simplify everything.
-5n-8-56n=8
Put the variables on one side and the numbers on the other.
-5n-56n=8+8
Combine like terms.
-61n=16
n=-16/61
Hope I helped! :)
