If there are 170 students in 12th grade, what percentage of the twelfth grade students have more than one college in mind? 1 college= 75 students 2 college= 27 students 3 or more colleges = 23 students

29.4%

Step-by-step explanation:

This question is a little confusing because the numbers added up do not equal 170, but I'm guessing there are students that have 0 colleges. There are 50 students in total with more than 1 college in mind. 50 divided by 170 is about 29.4%

it has to have an angle of 90 degrees

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
