Answer:
$35 for each sweater
Step-by-step explanation:
First subtract the skirt $160 - $20 = $140
Then Divide to find cost of each sweater $140/4 = 35
Answer: 35
The digit 2 is in the ten thousands place
Answer:
The magnitude is 
The direction is 
i.e toward the x-axis
Step-by-step explanation:
From the question we are told that
The function is 
The point considered is 
Generally the maximum rate of change of f at the given point and the direction is mathematically represented as

Hello,
If 12 balls were pitched to each of the 9 players at practice, then
12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 balls were pitched total.
This is also equal to (12)(9) = 108 balls.
108 balls were pitched during practice.
Hope this helps!
