Answer:
Step-by-step explanation:
sin(-430)=-sin(430)=-sin(360+70)=-sin 70
Answer:
Option C. The range is y≥2
Step-by-step explanation:
To solve this, we're gonna demonstrate that all options except option C. are wrong.
Option A. The vertical line confirms that the graph is a function. FALSE.
The vertical line is called the y-axis and it's used as a reference to graph functions. It does not confirm that a graph is a function.
Option B. The domain is x≥2. FALSE.
The domain of a function is the set of possible values of the independent variable "x". In this case, we can deduce from the graph that the variable "x" can take values less than 2.
Option C. The Range is x≥2. TRUE.
The range of a function is the set of all output values of a function. We can deduce from the graph that the variable "y" takes values greater than 2. For that reason, the statement is true.
Option D. This piecewise function is made out of 4 intervals. FALSE.
The function is made out of two intervals. A concave function for x≤2 and a line for x≥2.
Option E. Each interval of the piecewise function contains a graph of a linear function. FALSE.
When x≤2, the graph corresponds to a concave function. So, this interval is not linear.
You can draw a diagram of the situation, representing it by a right triuangle.
In the right triangle the hypotenuse is the distance indicated by the radio signal, 1503 m, and the angle is 41°.
The opposed leg to 41° is the height of the ballon.
Then you can use the sine trigonometric function.
sine (41°) = opposed leg / hypotenuse = x / 1503 m => x = 1503m * sine(41°)
=> x = 986m.
Answer: 986m
Answer: 5w⁴ + w²
Step-by-step explanation: Pic is attached. Hope this helps. Sorry for bad handwriting, Im writing with a mouse.
Even numbersso each dice has numbers1,2,3,4,5,6the eve numbers are2,4,6odd are others1,3,5so 1/2 are odd
therefor 1/2 of 60 is how many times it would get even1/2 of 60=1/2 times 60=30
No not good predicitionmy prediction would be 30 times
