D= b^2-4ac
D= 9-4*1*2
D=1
X= 3+1/2 OR 3-1/2
X= 2 Or 1
Wouldn't it just be 300 kilometers per hour as the answer?
We are given with the data revealing about the median age of an American man marries for the first time in a specific year. In this case, we are asked to determine the average rate of change during a ten-year interval. To have a negative average rate of change, the proceeding decade's median age should be less than the number before. In this case, all of the choices lead to negative average rate of change.
Answer:
12.6491106
Step-by-step explanation:
With respect to the angle formed by the bottom of the
ladder with the ground
cos T = 6/14 = 3/7
T = inverse-cosine(3/7) = 64.623006647 degrees
sin(64.623006647) = h/14
h = 14*sin(64.62300647) = 12.6491106
The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.
