Answer:
<h2>89.5°</h2>
Step-by-step explanation:
Using the vector formula
|u| = magnitude of vector u
|v| = magnitude of vector v
u.v is the dot product of vector u and v
Given |u| = 88, |v| = 99 and u.v = 77, to get we will substitute the given values into the equation above;

Answer:
Step-by-step explanation:
Solve x^2 + 6x + 4. Here the coefficients of the quadratic are a = 1, b = 6 and c = 4. The discriminant is therefore b^2-4ac, or, in this case, 6^2-4(1)(4), or 20.
The roots are:
-6 ± √20
x = ---------------- = -3 ± √4√5: x = -3 + 2√5 and x = -3 - 2√5
2
The -3 comes from the -6/2 in the application of the quadratic formula.
Answer A is correct.

Answer:
I will: Multiply 32 times 20 to get the total cost of the foods and tickets. Then I will add the total cost of the tickets and the total cost of the bus to get the total cost of the trip. Lastly I will divide the total cost of the trip by 2 to find out how much money the class need to earn.
Solution: 32 • 20 = 640 + 900 = 1,540 ÷ 2 = 770
Answer: 770
