Answer:
a couple of irrational numbers: -16±4√19, approximately {1.436, -33.436}
Step-by-step explanation:
Your question can be cast as the quadratic equation
x² +32x -48 = 0
The solutions can be found using the quadratic formula:
x = (-32 ±√(32² -4(1)(-48)))/(2(1)) = -16±√304 = -16±4√19
_____
<em>Comment on the equation we used</em>
We notice that when p and q are roots, the equation can be written ...
(x -p)(x -q) = 0 = x² -(p+q)x +pq
You want p+q = -32, pq = -48, so the equation is ...
x² -(-32)x +(-48) = 0
x² +32x -48 = 0 . . . . . . with parentheses eliminated
Answer:
-1
Step-by-step explanation:
The radian gives the coordinates: (
(found using the unit circle)
cot=x/y
Plug the x and y coordinates into their respective places in the equation.
You get the answer of -1.
1.2 is the answer you want
Answer:
38.18%
Step-by-step explanation:
Experimental probability is probability that is determined on the basis of the results of repeated experiments.
Experimental Probability = The number of times a result happens / The number of times the experiment is carried out *100%
In this problem, The number of times a result happens is the number of times Pedro sees heads, which is 21. The number of time the experiment is carried out is 55.
So the result is 55/21 *100% = 38.181818... * 100%= 38.18%
Hope you learn with joy and high grades !
