Answer:
no: 6+3 = 9
Step-by-step explanation:
In order to construct a triangle with given side lengths, sum of any two side length must be greater than the third side length.
Here we can see that:
6 + 3 = 9, which is defying the required condition.
Hence, it is not possible to construct a triangle with side lengths 3, 6, and 9 units.
Answer: Rises to the left and falls to the right
Step-by-step explanation:
Use the degree and the leading coefficient to determine the behavior.
There is a good video called "Describing End Behavior Using Limit Notation" by Mario's Math Tutoring, and it helps to show you how to find the end behavior with limits.
Answer:
45.6 mph
Step-by-step explanation:
Well,
If Bird A is EXACTLY 5 times as fast as Bird B, then it can reach 228 mph and Bird A can only reach 45.6 mph.
Answer:
Step-by-step explanation:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.
Step-by-step explanation:
Let x miles/hr be the speed of the plane in still air and y miles/hr be the speed of the wind.
We have 10hr * (x + y)miles/hr = 880 miles
and 20 hr * (x - y)miles/hr = 880 miles.
=> (x + y) = 88 and (x - y) = 44.
Therefore 2x = 88 + 44 = 132 and x = 66.
The speed of the plane in still air is 66 miles per hour.
