Answer:
Step-by-step explanation:
We are given an expression to solve for the displacement (x), so in order to find velocity (v), we need to differentiate the function.

Using this equation, we can find the velocity if a value of t is given.
Answer:
13 feet is remaining because
Step-by-step explanation:
12 1/4-3 1/3 (12*4=48+1=49)(3*3=9+1=10)
49/4-10/3
196-40/12
13
M∠C = m∠F, There are different additional facts that would guarantee the triangles are similar. One is if you are told that the length of AB is twice the length of DE. Another is if angle C is congruent to angle F. You only need one of the two facts above. Are you given choices?
2. an=20+an−1 and a1=145
she starts with 145 so a1=145 and then adds 20 every month: an=20+an−1
Answer:
D. She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.
Step-by-step explanation:
Find the rate of change between first two ordered pairs and the second two ordered pairs:
1. Points (2,4) and (3,9). Rate of change:
2. Points (3,9) and (4,16). Rate of change:
The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.
