Answer: option 1 is the correct answer
Step-by-step explanation:
This equation is one of the Newton's equations of motion.
The equation is f = v + at which represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t.
To determine an equivalent equation solved for a, we will make a the subject of the formula.
f = v+at
subtracting v from both sides of the equation, it becomes
f-v = 0 + at
Dividing both sides of the equation by t, it becomes
f -v = at
a = (f-v)/t
Option 1 is correct answer
Answer:
<em>Average rate of change is </em><em>-78.</em>
Step-by-step explanation:
A talent competition on television had five elimination rounds. After each elimination, only one-third of the contestants were sent to the next round.
The table that shows the number of contestants in each round of the competition is,
x f(x)
1 243
2 81
3 27
4 9
5 3
Average rate of change is the change in the y-value divided by the change in the x-value for two points on the graph.
i.e 
So, the average rate of change of 
from 
to 
is,
Since f(x) is decreasing, so rate of change is negative.
Here,
Perimeter (P)=86 feet
Length (l)=25 feet
Let, width(b)= x feet
Then,
Perimeter= 2(l+b)
86=2(25+x)
43=25+x
x=18
Hence, required width is 18 feet...
Answer: Ashley had more yarn, 1 yard = 3 ft 3 times 4 = 12 so 3 yards is 12 feet.
