Determine the domain of the function. f(x)= sqrt of 7+x

x∈R {x ≥ -7}

Step-by-step explanation:

The domain of the function can only include real numbers. This means whatever happens under the square root sign (i.e. the radicand) cannot be less than 0 (since you can't take the square root of a negative number).

To find the domain, set the radicand ≥ 0:

7 + x ≥ 0

x ≥ -7

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

answer: the answer is 127 degrees
