The slope of a vertical line is undefined, D.
If you were to try to solve use something like the rise over run method, you would end up with a 0 in the denominator. Since dividing by 0 gives you an undefined result, the slope would be undefined.
Answer: 18:54
:))) have a good day.
Answer:
The number of the students is 20.
Step-by-step explanation:
Total number of students in the speech contest = 90
Number of students that gave their speeches yesterday =
of 90
=
x 90
= 60
Number of remaining students who have not given their speeches after the first day = 90 - 60
= 30
Number of students that gave their speeches today =
of 30
=
x 30
= 10
Number of students that have not given their speeches = 30 - 10
= 20
Thus, 20 students have not given their speeches.
Step-by-step explanation:
Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.
so,
AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45
AB = sqrt(45) ≈ 6.7
CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40
CD = sqrt(40) ≈ 6.3
