Answer:
Domain: [-3, 5]
Range: [-5, 4]
Step-by-step explanation:
The first thing is to define what is the domain and the range. The domain of a function f (x) is the set of all the values for which the function is defined, and the range of the function is the set of all the values that f takes.
In other words, the domain is the value on the "x" axis and the range is the value on the "y" axis.
In this case, both are an interval, the domain would be from -3 to 5 and in the case of the range it would be from -5 to 4.
Domain: [-3, 5]
Range: [-5, 4]
The ground is supplementary. That means it equals 180 degrees. (A circle is 360. The ground is half the circle)
So u set up the equation as
180=22x+14x
180=36x
/36 /36
5=x
But you need to find the 14x
14(5)
=70 degrees before the tree hits the ground
Answer:
There is 1 solution.
Step-by-step explanation:
0.5(x - 3) = 3x - 2.5
0.5x - 1.5 = 3x - 2.5
-2.5x = -1
x = 0.4
There is 1 solution.
Answer:
x = 3
Step-by-step explanation:
10x + 1 = 12x - 5
Subtract 1 from each side
10x = 12x - 6
Subtract 12x from each side
-2x = -6
Divided by -2
x = 3
