You subtract 1260 from 1964. Then you take that number and divide it by 8.
This gives you the answer of $88 per skull.
Answer:
a < -
Step-by-step explanation:
Using the discriminant Δ = b² - 4ac
For a polynomial to have 2 real roots
b² - 4ac > 0
Given
p(x) = (a + 1)x² + 2ax + (a + 2)
with a = a + 1, b = 2a and c = a + 2, then
(2a)² - 4(a + 1)(a + 2) > 0 ← expand and simplify left side
4a² - 4(a² + 3a + 2) > 0
4a² - 4a² - 12a - 8 > 0
- 12a - 8 > 0 ( add 8 to both sides )
- 12a > 8
Divide both sides by - 12, reversing the symbol as a result of dividing by a negative quantity
a < , that is
a < -
Speed of Jordan while driving from his home = 56 mph
After Jordan travels 2 miles then Roman started from his house.
Speed of Roman while driving after leaving home= 60 mph
Let after t hours they meet.
And let they cover the distance =d i.e point at which meet.
After time t distance covered by Jordan= 56 t +2
Roman has to cover the distance to catch Jordan= 60 t
A.T.Q
⇒ 60 t=56 t + 2
⇒4 t=2
⇒t=1/2
So, when d = 56×1/2+2=28+2=30 miles
Roman will catch Jordan.
From the above four solutions ,( C.) d = 56 t ,d = 60 t – 2 , Satisfies the above criteria.
So C is the correct answer.
