Answer:
4
Step-by-step explanation:
Calculation of the discriminant of the polynomial : x⋅2−4⋅x+5
1. Applying the formula to calculate the discriminant Δ=b2−4⋅a⋅c with : a=0, b=−2,c=5
2. Δ=(−2)2−4⋅(0)⋅(5)=4=4
3. The discriminant of the polynomial x⋅2−4⋅x+5 is equal to 4
Answer: 8/17
Explanation:
2, 4, 6, 8, 10, 12, 14, 16 are all the possible even numbers from 1 through 17.
<span>First we define Charlene's the average time, which is (8.4 + 8.6 + 8.3 + 8.5 + 8.7 + 8.5)/6 = 8.5. Normal time is 8.5/1.1 = 7.7. Charlene is faster than normal.</span>
If you calculate the problem correctly you should end up with:
(A)-(3)
Which equals:
= -3
Hope this helps... have a good day!
35+55+a=180
90+x=180
-90. -90
A= 90
