Answer:
12
Step-by-step explanation:
Given equation is f(x)=-3x^3-x^2+1
We have to identify the graph that has same end behaviour as of given equation.
It seems that you have missed to attach the given graph in question. So i will explain about how to find correct graph.
Given function has highest exponent 3 so that means degree = 3
which is an odd number.
We know that graph of odd degree polynomial always starts and ends in opposite direction.
Leading coefficient of given function is -3 which is negative.
We know that when leading coefficient is negative then graph starts from top.
Hence graph of given function will start from top and go to the bottom as shown in picture.
Now any given graph which opens from up and ends in bottom will be answer.
All polynomials having odd degree and negative leading coefficient will also have similar graph.
Step-by-step explanation:
In every triangle, length of two sides must be greater (not equal or lesser) than the length of third side of the triangle...so it is not possible to have triangle of side lengths 9 9 and 20. Apologies if i m wrong.
Answer:
D
Step-by-step explanation:
Depending on the number of defects in 6th car, we have 3 cases:
- 3,4,6,7,9,10 (median 13/2 =6.5)
- 4,6,7,7,9,10 (median 14/2 = 7)
- 4,6,7,9,10,12 (median 16/2 = 8)
To find mean we can use the sum of numbers given (= 36) and add either 3, 7, or 12 to it and then divide by 6 (number of cars).
(36 + 3) /6 = 39/6 = 6.5 (== median above)
(36 + 7) /6 = 43/6 = 7.1 (does not equal median above)
(36 + 12) /6 = 48/6 = 8 (== median above)
Answer: D (I and III only).
