From the moment the friend passes the bicyclist, his friend covers a distance over time t of (3.63 m/s)*t.
The bicyclist covers a distance of 1/2*(2.11 m/s^2)*t^2. They meet when these distances are equal:
3.63 t = 1.055 t^2 ==> 1.055 t^2 - 3.63 t = 0
==> t = 0 s or t = 3.44 s

Answer:
3 a^12 b^5
Step-by-step explanation:
Simplify the following:
(15 a^8 b^4 a^4 b)/5
15/5 = (5×3)/5 = 3:
3 a^8 b^4 a^4 b
3 a^8 b^4 a^4 b = 3 a^(8 + 4) b^(4 + 1):
3 a^(8 + 4) b^(4 + 1)
4 + 1 = 5:
3 a^(8 + 4) b^5
8 + 4 = 12:
Answer: 3 a^12 b^5
82 degrees and 98 degrees
First, find the original equation
180 = (x) + (x + 16)
Simplify: 180 = 2x + 16
Next, use the subtraction property of equality to subtract 16 from both sides
180 - 16 = 2x + 16 - 16
Simplify: 164 = 2x
Then, you can use the division property of equality to find the value of x
164/2 = 2x/2
Simplify: 82 = x
Now, we know that the first angle equals 82 degrees and that the second angle equals 98 degrees
