Answer:
Average Velocity= 70 miles per hour
Step-by-step explanation:
Distance= s
Time = t
s(t)=10t^2
Putting the values
s(2) = 10 (2)^2= 10&4
s= 40
s(5) = 10 (5)^2 = 10*25
S(5)= 250
The average velocity is defined as the rate of change of speed in unit time.
So
Speed= distance/time
Velocity = Speed in a definite direction
Average Velocity= Displacement/ Time
Average Velocity= Change in distance/ Change in time
s(5) - s(2)/ t(5)- t(2)
= 250-40/5-2= 210/3= 70 miles per hour
Answer:
(x +4)(x -1)(x +1)
Step-by-step explanation:
The sum of coefficients is zero, so we know that x=1 is a root and x-1 is a factor. We also notice that pairs of terms have coefficients in the ratio 1:4, so x+4 will also be a factor.
= (x+4)(x^2) -1(x+4)
= (x+4)(x^2 -1)
= (x +4)(x -1)(x +1) . . . . . use the factoring of the difference of squares
3.9 can be rounded to 4.
5.3 can be rounded to 5.
4 x 5 = 20
That tells you that 3.9 x 5.3 has a digit in the tens place.
Then you can proceed to multiply 39 and 53, which equals 2067.
(Note: I removed the decimals on purpose)
Now we know that in 2067, the 2 should be in the tens place. That means 0 is in the ones place and that 6 is in the tenths place. That leaves 7 to be in the hundreths place.
Therefore, 3.9 x 5.3 = 20.67
For any given rational function, the vertical asymptotes represent the value of x that will make the denominator of the function equal to zero. The horizontal asymptote represent the value of y that results to an undefined value of x. The asymptotes serve as limits for the domain and range of the function.
