Answer:
Its 40 for the first and 20for the other one
Step-by-step explanation:
I just took the test.
To determine the length of time it would took for the biker to cool down, we need the rate that would relate the distance he traveled to cool down per units of time. For this problem, the rate is given as 0.25 miles per minute. So, we simply divide the total distance he traveled with this rate. We calculate as follows:
time to cool down = distance / rate
time to cool down = 35 miles / 0.25 miles / minute
time to cool down = 140 minutes or 2 hrs and 20 minutes
Therefore, the biker would need to cool down for about 2 hrs and 20 minutes if he traveled for 35 miles.
Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,
56x = (18√14)²
56x = 4536
x = 
x = 81
2). By applying geometric mean theorem,
16x = (8√21)²
16x = 1344
x = 
x = 84
The vertex form:
The axis of symetry is x = h.
We have
Substitute:
<h3>Answer: x = -3</h3>
