The given sequence is
The common ratio can be found using any two consecutive terms of the geometric sequence.
The correct answer is the last choice.
Answer:
2:1
Step-by-step explanation:
average age of both = 40
average age of teachers = 35
average age of professors = 50
35 + 35 + 50 = 120
120 / 3 = 40
<u>Answer:</u>
The correct answer option is C) y = -2/3x - 13/3.
<u>Step-by-step explanation:</u>
We are given a straight line graph with one known point and we are to find its equation.
We will take one more point on the line to find the slope.
(-5, -1) and (-2, -3)
Slope (m) =
Now finding the y-intercept:
Therefore, the equation of this line is y = -2/3x - 13/3.
John should use his protractor to mark off a 70° angle whose vertex is one end of his 5 cm segment. If John is unsure how to do that, he can look up videos on how to use a protractor.
John could also construct a segment 13.74 cm long at the end of his segment that is perpendicular to the one he has. The angle formed between the other end of his 5 cm segment and the end of the 13.74 cm segment will be 70°.
Another choice John has is to draw an arc from each end of his 5 cm segment that has a radius of 7.3 cm. The point where these intersect over the middle of his segment will form an angle of 70° when a segment is drawn from there to the end of his 5 cm segment.
