A because he only teaches one thing calculus
Answer:
Patient A - 150 mg
Patient B - 50 mg
Step-by-step explanation:
Since patient A gets three times more, 50 times 3 is 150. 150 plus 50 is 200, therefore, patient A gets 150 mg and patient B gets 50 mg. I hope this helps :)
Answer:
7 sides
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
Now, exterior angle of the point with interior angle of 120 is; 180 - 120 = 60 (angle on a straight line)
For the others, it is; 180 - 130 = 50
Thus;
60 + 50n = 360
50n = 360 - 60
50n = 300
n = 300/50
n = 6
Thus,number of sides = 6 +1 = 7 sides
You don't show the details but you would have to multiply two linear equations to produce a quadratic equation. ex:
y2*y1=(ax+b)(cx+d)=acx^2+(ad+bc)x+bd
Step-by-step explanation:
I. x - y = 4 --> y = x - 4
II. x + y = 4 --> y = 4 - x
Solution is x = 4 and y = 0
