A. would have the highest pitch because the sound vibration are close together and it would also be the fastest. B is incorrect because the sound waves are very which would give it a deeper voice and it would be the slowest
Hope this helps
Let's talk about the choices
◯ ∠4 and ∠5 . . . . . . . . these are complementary angles whose sum is 90°
◯ ∠7 and ∠9 . . . . . . . . these are vertical angles, equal to each other
◯ ∠2 and ∠3 . . . . . . . . these are supplementary angles that together form a straight line. They are a linear pair.
◯ ∠1 and ∠2 . . . . . . . . these are "adjacent" angles in the quadrilateral that also includes ∠9 and ∠10.
The appropriate choice is ...
◉ ∠2 and ∠3
We must add 2/3 and 2/7.
We have to convert these to fractions with "21" as the denominator.
14/21 plus 6/21 =
20/21 of the quizzes have been corrected.
Answer:
80
Step-by-step explanation:
5(1+3)^2
Due to PENDAS, you will first need to do the root
5(4)^2
5(16)

Answer:
y = 2x and y = -7x +9
Step-by-step explanation:
The two "linear" functions are those that have a constant rate of change. Actually, the slope (inclination) they show when plotted is that "rate of change".
The function : y = 2x, has a constant positive rate given by its slope (2).
The function : y= -7x +9 has a constant negative rate given by its slope (-7)
The other two functions are quadratic, represented by parabolas, and therefore don't have a constant rate of change.
