Answer:
-3.33 ft. per second
Step-by-step explanation:
The rate of change of an object can be calculated by finding the difference in position between the starting point and end point, and then dividing by the difference in time between the starting time and end time. Using the values provided in the question we can calculate the following
= 3.33 ft. per second
With the calculation above we can see that the rate of change during these 15 seconds is 3.33 ft. per second. Since the endpoint is further down below ground level then we were descending which means that the rate of change would be a negative (-3.33 ft. per second)
No. Not all radical equations have an extraneous solution. <span>However, squaring both sides of an </span>equation<span> can create </span>extraneous solutions.<span>

Answer:
x = 4
Step-by-step explanation:
Given
(x - 7) = - 2
Multiply both sides by 3 to clear the fraction
2(x - 7) = - 6 ← distribute left side
2x - 14 = - 6 ( add 14 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4

Answer: 13</h3>
=========================================================
Explanation:
We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.
Add up the values along the bottom row. Set the sum equal to 50 and solve for m
m+8+29 = 50
m+37 = 50
m = 50-37
m = 13
Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.
