Answer:
x is all real numbers
Step-by-step explanation:
The domain is the values for the inputs
Since all values are allowed for the input
The domain is all real numbers
A. 6x-y=1 can go to 6x-y-1=0 and then 6x-1 = y
The distance from the owl to the squirrel would be found by using the law of sins/co-sins
Cos (known angle) = adjacent leg / hypotenuse ( distance wanted)
cos(50) = 14 / x
x = 14 / cos50
x = 21.78 feet
The problem doesn't say if the answer should be rounded or not. You may have to round the answer if needed.
The maximum speed of a boat at 30 feet length of water is 0.093 nautical miles/hour or knots.
<u>Step-by-step explanation:</u>
- The equation for the maximum speed, s is given by s²= (16/9)x
- where, x is the length of the water line in feet.
It is given that, the modeled equation s²= (16/9)x is used to find the maximum speed in knots or nautical miles per hour.
The question is asked to find the maximum speed when the length of the water is 30 feet.
Therefore, to find the maximum speed in 30 feet water, the given modeled equation is used. So, substitute the 30 feet in place of x.
<u>Now, calculating the maximum speed :</u>
s² = (16/9)(30)
s² = 480 / 9
s² = 53.3
Taking square root on both sides,
s = √53.3
s = 7.3
The maximum speed of a boat at 30 feet length of water is 7.3 nautical miles/hour or knots.
Absolute value is alwas positive
so all of them excet the 3rd one are false
|w|=0 has 1 solution
if the last one was |w|=1 then ther would be 2 solutions, -1 and 1
answer is |w|=0
