You have to ask yourself “how many half hours segments are in 2 hours?” The answer is 4. Now, since you want to find out how many miles the boat can travel in half an hour, divide 27 by 4 (because there are four half hours in 2 hours). 27 divided by 4 equals 6.75. The boat travels 6.75 miles in half an hour.
Answer:
Yes, the rule is that x-coordinates cannot repeat, but it does not matter with y-coordinates

Answer:
3.856 seconds
Step-by-step explanation:
Set d=10 and solve for t.
10 = -12t^2 -3t +200
12t^2 +3t -190 = 0 . . . . . . subtract the expression on the right to put into standard form
This is a quadratic equation, so the quadratic formula can be used to find solutions. That formula tells you the solution to ...
ax^2 +bx +c = 0
is
x = (-b ±√(b² -4ac))/(2a)
__
We have a=12, b=3, and c=-190. The variable in our equation is t, not x. Putting these values into the formula, we find ...
t = (-3 ±√(3² -4(12)(-190)))/(2·12)
t = (-3 ±√9129)/24
t = (-3 ±95.546)/24 = -4.106, +3.856
The coconut will be about 10 ft off the ground after 3.856 seconds.
<span>y+3=-4(x-6) so you want to go ahead and multiply the parentheses by -4 to get -4x + 24 then you subtract the 3 to the other side to get y=-4x+21 so the slope is -4</span>
Answer:
D) 1980 to 2000
Step-by-step explanation:
Finding the average rate of change in each interval to determine the greatest one.
Production per interval
1950-1960 = = 10 million
1960-1970 = = 20 million
1970-1980 = = 30 million
1980-2000 = million
Rate of change (1950-1960)=
Rate of change (1960-1970) =
Rate of change (1970-1980)=
Rate of change (1980-2000)=
∴ rate of change between 1980 to 2000 is 126.78%
