The key thing to look for to determine whether a sequence is geometric is to see whether the ratio between consecutive terms - the number I would multiply one term by to get the next - is constant.
By inspection, we see that the fourth answer choice satisfies that, as 
Why not the first? We have 
The third choice is not a geometric sequence, but rather an arithmetic sequence, where the difference between consecutive terms is constant. Just to make sure that it isn't geometric, we compute 
The second sequence is not geometric (although it does eventually converge to 1, but not its corresponding series), as 
Yes is would the diameter of -1 mile east of the integer
Answer:
Step-by-step explanation:
first we need to find the slope bu using the slope formula and ur two sets of points
slope = (y2 - y1) / (x2 - x1)
(7,1)...x1 = 7 and y1 = 1
(-12,-6)....x2 = -12 and y2 = -6
now we sub
slope = (-6 - 1) / (-12 - 7) = -7/-19 = 7/19
now...in y = mx + b form, the slope will be in them position
y = mx + b
slope(m) = 7/19
use either of ur points.....(7,1)...x = 7 and y = 1
now we sub and find b, the y int
1 = 7/19(7) + b
1 = 49/19 + b
1 - 49/19 = b
19/19 - 49/19 = b
- 30/19 = b <======= ur y int
so ur equation is : y = 7/19x - 30/19
Answer:
A
Step-by-step explanation:
In a parallelogram the opposite angles are congruent, thus
∠ JHF = ∠ JEF = 142°
∠ JHF and ∠ FHG are adjacent angles and are supplementary, thus
∠ FHG = 180° - 142° = 38°
The sum of the 3 angles in a triangle = 180° , thus
∠ HFG = 180° - (90 + 38)° = 180° - 128° = 52° → A
Answer:
Step-by-step explanation:
In right triangles only:
The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)
The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)
Therefore, we have the following equation:
