Answer:
8 / 17
Step-by-step explanation:
So cosine is adjacent ÷ hypotenuse.
Adjacent = 8
Hypotenuse = 17
8 / 17

Answer:
7200 people
Step-by-step explanation:
Let's say x amount of people tried out.
After round 1: 1/2 x are left.
After round 2: 1/3 (1/2 x) are left
After round 3: 1/4 (1/3(1/2 x))) are left
Each time we multiply by the fraction that are left. By the end we will have
1/6(1/5(1/4(1/3(1/2 x))))
So to find it multiply the denominator out:
To find x, we set it equal to 10.
Step-by-step explanation:
y = -3x² + mx + 10
dy/dx = -6x + m.
When dy/dx = 0, -6x + m = 0. => x = m/6.
We have y = -3(m/6)² + m(m/6) + 10 = 37.
=> -m²/12 + m²/6 = 27
=> -m² + 2m² = 324
=> m² = 324
=> m = 18 or m = -18.
Account 1 : y = 2500(1.078)x
account 2 : y = 2500 + 300x
after the second year a1 exceeds a2
after 2 years, a1 = 5390
after 2 years , a2 = 3100
