Answer:
She caught up with Jordan at 6:39 AM
Step-by-step explanation:
We solve this question making linear functions for the distances that Jorden and his mom have driven, and then we equalize them to find the moment they caught up.
Jorden leaves home for school on his bike everyday at 6:00 AM, traveling at 32 km/h.
Her mom will have left 15 minutes after he left, when he will already have traveled
So, his position after t minutes can be modeled by the following function:
His mom
His mom goes after him starting from home, so the initial position is 0, with a velocity of 52 km/h. So her position can be modeled by the following function:
At what time did she catch up with Jorden,
She catches up t minutes after 6:15 AM.
t is found when
So
0.4 of an hour is 0.4*60 = 24 minutes.
So she catched up with Jordan after 6:15 AM + 24 minutes = 6:39 AM
Answer:
C.
Step-by-step explanation:
Recall that the sum of the (3) interior angles of a triangle <em>must</em> equate to 180.
In other words:
Where x is our unknown angle. So, we need to solve for x.
On the left, add 55 and 20:
Subtract 75 from both sides. The left side cancels:
Therefore, the third angle is 105 degrees.
Our answer is C.
P=2.50x+100
The slope of the function is 2.50 which represents the commission Dylan makes for each computer sale. :)
