Answer:
if the x is supposed to be squared, the coordinates are (3,2)
X is Andrews age and if x stands for Andrew then
x-28=5x-160
then you would do =+160 to both sides getting x+132=5x
subtract the x from the side with 132 and then do 4 divided by 132
getting 33
Andrew is 33
80% converted to a decimal is 80/100=0.8
Multiply the total with the percent 685*0.80
The answer is 540
For this case what you have is the same as a rectangle triangle where you have as data the degree of inclination of the hypotenuse with respect to the base and the height of the triangle.
We have to find the value of the hypotenuse.
For this we use the following trigonometric relationship:
senx = C.O / h
Where
x: angle
C.O: opposite leg
h: hypotenuse.
Substituting the values we have:
sen (12) = 100 / h
We cleared h:
h = 100 / sin (12)
h = 480.97 m
Answer:
Galileo should walk 480.97 m up the inclined plane
Answer:
Let's use these two sets given to explain what is the domain.
Each value from the left set is x, and from the right is f(x).
If we plug any x from the left set in the function, we'll get f(x) that corresponds to it and that's exactly what the arrows are showing.
Domain of the function is, basically, a set of all values x can have.
In this case, it's easy to see, those are all members of the left set (-6, 1, 5, 8), but sometimes this set can have lots and lots of members, even infinity.
