Answer:
sinA=15/17 and cosA=8/17
Step-by-step explanation:
sine is opposite side over hypotenuse and cosine is adjacent side over hypotenuse
The probability of landing on the 4 spinners divided into four equal parts will be P=25%
<h3>What is probability? </h3>
Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Here the spinner is divided into four parts of the colours green, red, yellow, and blue.So the number of the sample variable are:-
P(S)=[red,green,yellow,blue]=[4]
The favourable outcome is given as:-
F[s]=[1]
So the probability will be given by:-
P={1}÷{4}=0.25=0.25x 100=25\%
Hence the probability of landing on the 4 spinners divided into four equal parts will be P=25%

Answer is 3 seconds
When the bullet reaches the ground, ground being x in graph (and here its s which is = 0)
s = -16t^2 + 48t
s = 0, solve for t
0 = -16t^2 + 48t
0 = t ( -16t + 48)
0 = 16t ( - t + 3)
now you have two equation
0 = 16t and 0 = -t +3 ( you can look at the graph line touches x twice)
0 = 16 t
0 = t ( you know its false, because time = 0)
You are left with
0 = -t + 3
t = 3
It takes 3 seconds for the bullet to return to the ground.
