<u>First, a complementary angle are two angles that add up to 90. while supplementary add up to 180. </u>

Complementary angles; 1 & 2, 3 & 4, 9 & 10, 11 & 12. (these all make one line which equals 180.)

Supplementary angles; 7 & 8, 5 & 7, 6 & 5, 8 & 6. (these all make up a 90 degree angle.)

Hope this helps. <3

complimentary angles equal 90 degrees so 1 and 2, 3 and 4, 9 and 10, 11 and 12 would be complimentary

supplementary angles equal 180 degrees so 6 and 5, 5 and 7, 7 and 8, and 8 and 6 would be supplementary

-3r + 7 - 3r - 12 in simplest form

Akimi4 [234]

Since the co-efficient or "r" is "-3" and "-3", it will simplify to "-6" as -3-3= -6.
then the two constant terms with are "7" and "-12" will simplify to "-5" as 7-12=-5. therefore, the simplest form is -6r -5

hope it helped!

A volleyball reaches its maximum of 13 feet, 3 seconds after it is served. What quadratic formula could model the height of the

Katena32 [7]

Answer:

$H=-(t-3)^2+13$

Step-by-step explanation:

The path covered by the volleyball will be a downward parabola with the vertex being the highest point of the ball.

A general form of a downward parabola is given as:

$y=-a(x-h)^2+k$

Where $(h,k)$ is the vertex of the parabola and 'a' is a constant.

Now, let 'h' be the vertical height and 't' be the time taken.

So, the equation would be of the form:

$H=-a(t-h)^2+k$

Now, as per question:

h = 2 seconds, k = 13 feet.

$H=-a(t-3)^2+13$

Now, taking a = 1. So, the formula that can be used is:

$H=-(t-3)^2+13$
