There are 60 minutes in an hour.
8 / 60 = 0.1

Answer: 24
<u>Step-by-step explanation:</u>
Let's find one solution:
3x² + 7x + c = 0
a=3 b=7 c=c
First, let's find c so that it has REAL ROOTS.
⇒ Discriminant (b² - 4ac) ≥ 0
7² - 4(3)c ≥ 0
49 - 12c ≥ 0
-12c ≥ -49
Since c must be a positive integer, 1 ≤ c ≤ 4
Example: c = 4
3x² + 7x + 4 = 0
(3x + 4)(x + 1) = 0
x = -4/3, x = -1 Real Roots!
<em>You need to use Quadratic Formula to solve for c = {1, 2, 3}</em>
<em />
Valid solutions for c are: {1, 2, 3, 4)
Their product is: 1 x 2 x 3 x 4 = 24

None of the above
Step-by-step explanation: -6(6+2) + 8 = -40 so -66 + 2 +8 = 56 and -66 - 4 = 70
Answer:
The distance between the ship and the island is
.
Step-by-step explanation:
The ship's azimuth is the direction measured as an angle from the north.
You should draw a diagram of the situation.
From the information given we know two distances and the angle between them and we want to find the distance between the ship and the island.
To find the distance between the ship and the island we can use the Law of Cosines.
<em>If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of cosines states:</em>
![c^2=a^2+b^2-2ab\cdot cos(C)](https://tex.z-dn.net/?f=c%5E2%3Da%5E2%2Bb%5E2-2ab%5Ccdot%20cos%28C%29)
This law is useful for finding: the third side of a triangle when we know two sides and the angle between them like in this case.
The angle is
![\theta=48\°+(360-332)\°=76\°](https://tex.z-dn.net/?f=%5Ctheta%3D48%5C%C2%B0%2B%28360-332%29%5C%C2%B0%3D76%5C%C2%B0)
And the distance is given by
