Answer:
Hence, option 1 is correct.
Hence, last option is correct.
Step-by-step explanation:
We have given two function
and
Domain is the values x can take and
And range is the values y can take
Hence, x can take any real value in both the functions in f(x) and g(x)
Hence, option 1 is correct
Now, for range
range of f(x) can be any real number
But range of g(x) can be positive number
Hence, last option is correct.
Rest all options are incorrect.
Answer:
c
Step-by-step explanation:
See the graph for an example using the specific angles
See how the red segments are equal in length but going in opposite directions?
a. This can't be correct: it says is equal to its opposite. That is never true in Quadrant I where all tangent values are positive.
b. Not true in Quad. I. Consider .
Answer:
the base of the ladder is 27.89 ft away from the building
Step-by-step explanation:
Notice that this situation can be represented with a right angle triangle. The right angle being that made between the ground and the building, the ladder (32 ft long) being the hypotenuse of the triangle, the acute angle of being adjacent to the unknown side we are asked about (x). So, we can use the cosine function to solve this:
which rounded to the nearest hundredth gives;
x = 27.89 ft
