Answer:3
Step-by-step explanation:if you divide 3 and 15 is 5 so the answer is 3! Please give a lot of points!!!
Answer:
middle graph
Step-by-step explanation:
Soluton
The second (middle ) graph is the only one that works.
- First of all when you simplicity the right, you get y = x^2 - 1). That means that x does not go through 0,0. If you put x = 0 into x^ - 1 = 0, you get - 1. So on that basis alone both the first and third graphs are incorrect.
- Second, both xs in the factors are plus, so x^2 is plus, which means the graph opens upward.
The answer would be the distances that are not too large and not too small
A.legnth and width of a ball room
this would work because the next measurement is 1 mils and ball rooms are not that big
B. width of an eyelash. that is rediculously small so this is wrong
C. distanc from chicaco to san fransisco
way too far, use miles
D. height of a door
corect, door is apout 8 feet aprox
answer is A and D

Answer:
A. y = 3 cos (1/2) x.
Step-by-step explanation:
The y-intercept is 3 so it will contain 3 cos x (because y = cos x passes through (0, 1).
The graph of 3 cos x has been stretched horizontally by a factor 2 ( 3 cos x would pass through (π/2, 0) whereas the given graph passes through (π, 0).
So the equation is 3 cos(1/2) x
