Answer:
The measure of angle A is 
Step-by-step explanation:
we know that
Applying the law of cosines
substitute the values and solve for cos(A)
![cos(A)=[22^{2}+18^{2}-31^{2}]/(2(22)(18))\\ \\cos(A)=-0.193182\\ \\A=arccos(-0.193182)=101\°](https://tex.z-dn.net/?f=cos%28A%29%3D%5B22%5E%7B2%7D%2B18%5E%7B2%7D-31%5E%7B2%7D%5D%2F%282%2822%29%2818%29%29%5C%5C%20%5C%5Ccos%28A%29%3D-0.193182%5C%5C%20%5C%5CA%3Darccos%28-0.193182%29%3D101%5C%C2%B0)
Answer: non-linear 40 1/2 Step-by-step explanation: This is a non-linear function specifically it is an oscillating function The initial position of the weight occurs at t=0 and from the graph we see that at t=0, the weight position is 40 centimeters The weight is said to reach equilibrium when its position is at 0 cm. From the graph we can see that the function first reaches 0 cm at t=0.5 seconds or at t= 1/2 second

Quadratic formula is x=(-b+-sqrt(b^2-4ac))/(2a)
a= 1, b=-4, and c=3
Therefore, x=(-(-4)+-sqrt((-4)^2-4(1)(3))/(2(1))
Solve for both the plus and minus equations; the answers will be the roots to the quadratic equation.
first qn
4/36=1/9
total no. of ways to roll a dice=36
no. of ways to produce 7=3
(1+6=7, 2+5=7, 3+4=7)
no. of ways to produce 11=1
(5+6=11)
there are 4 ways in total. 4/36 simplify it to be 1/9
second qn im not sure but i think its
1/9 x 50 = 50/9 = 5 x (5/9)
round it off to the smaller whole no. which is 5 so i think its 5 times in 50 trials
