I honestly had problems with these myself but if I had to guess I would put down 2|3
The photo below has the answer
It is not periodic. A periodic dataset is a dataset that repeats the same pattern over time.
Y = -10x + 1...slope here is -10. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of a number, flip the number and change the sign. So our perpendicular line will need a slope of 1/10.
y = mx + b
slope(m) = 1/10
(5,7)....x = 5 and y = 7
now sub and find b, the y int
7 = 1/10(5) + b
7 = 1/2 + b
7 - 1/2 = b
14/2 - 1/2 = b
13/2 = b
so ur perpendicular line going thru (5,7) is y = 1/10x + 13/2
Answer:
x ≈ 34.28
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan29° = 
= 
( multiply both sides by x )
x × tan29° = 19 ( divide both sides by tan29° )
x = 
≈ 34.28 ( to the nearest hundredth )
