Answer: The sequence 3, 12, 26, ... is not a geometric sequence.
Answer:
Step-by-step explanation:
It appears that the number of bulbs produced on the first shift is quite a bit more than the second shift. 5.5 times more, actually. That means that the first shift's output is based on the second shift's output. Second shift produced an unknown number of bulbs, so we will call that number x. First shift produced 5.5 times more, so first shift produced 5.5x. The total number of bulbs produced between the 2 shifts is given as 16,250, so
x + 5.5x = 16,250 so
6.5x = 16,250 and
x = 2500
The second shift produced 2500 bulbs, and the first shift produced 5.5(2500) = 13,750 bulbs.
1) A Pythagorean triples is a set of three integers, a, b, c, that follow the rule a^2 + b^2 = c^2
2) Assumin c is the diagonal of your rectangle and the hypotenuse of the triangles, you are looking this:
13^2 = a^2 + b^2
=> 169 = a^2 + b^2
Two integer numbers that meet that equality are 5 and 12:
5^2 = 25
12^2 = 144
=> 5^2 + 12^2 = 25 + 144 = 169
=> 13^2 = 5^2 + 12^2
Now that you have the three numbers you know the dimensions of the figure and can calculate the area of the shaded part. I cannot do that for you becasue you did not include the figure.
<span>3x2− 5x + 5 = 0.
a=3 b=-5 c=5
A. a = 3, b = 5, c = 5
B. a = 3, b = −5, c = 5
C. a = 5, b = −5, c = 0
D. a = −3, b = 5, c = −5
answer is B
