Answer:

The ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.

Step-by-step explanation:

The quadratic function h(t) = -4.9t^2 + 22t + 5.5 represents the height of the ball above the ground, h(t), in meters, with respect to time, t, in seconds.

To find h(3), substitute t = 3 into the function expression:

h(3)=-4.9\cdot 3^2+22\cdot 3+5.5\\ \\=-4.9\cdot 9+66+5.5\\ \\=-44.1+71.5\\ \\=27.4

Meaning: the ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.

Two angles are supplementary. One angle measures 26o more than the other. Find the measure of the two angles.
nikitadnepr [17]
Supplementary angles are angles whose sum is equal to 180°.

Let one angle be x
The other angle is said to be 26°more than the other so it is x + 26

x + (x+26) = 180
x + x + 26 = 180
2x = 180 - 26
2x = 154
x = 154/2
x = 77

1st angle, x, is equal to 77°
2nd angle, x + 26°, is 77° + 26° = 103°

77° + 103° = 180°
180° = 180°

My other answer was was lacking (I also believe I should have furthermore edited it.), therefore I will attempt to explain the steps correctly this time. I don't know what exactly is requested nor what you are learning, but I suspect it would be combinations, factorials, and/or permutations, something along those lines. Firstly I figured out my answer using factorials. 

FROM: F,R,O,M. This obtains 4 letters.

4! (1 x 2 x 3 x 4)= 24 

I am unsure if this is what you are looking for though. I hope this helped a bit.
