Domain are all the possible x values of a function. When you look at a cosine graph you can see that it goes on into infinity in the x or horizontal direction. This means that all x values are included in cosine. Because of this the domain is:
all real numbers
or
(-∞,∞)
^^^ It can be written both ways
Hope this helped! Let me know if there is anything else I can do!
Answer:
96
Step-by-step explanation:
Total number of people attending the history museum is 200
Surveyed people are 25
Out of the 25, 12 people said yes
Therefore; the fraction which said yes = 12/25
To find the total number of people expected to say yes out of those that attended the history museum;
Fraction of the sampled that said yes × total number of people that attended.
= 12/25 × 200
= 96
Answer:
see below
Step-by-step explanation:
y = a ( x-0)^2 + 5 sub in the point given to calculate 'a'
1 = a (4)^2 + 5
-4 = 16a
a = - 1/4
y = -1/4 x^2 + 5
Answer:
-13 + 5*n-1 I think
Step-by-step explanation:
Answer:The equation y=8x - 30 could be the other one.
Step-by-step explanation:
Because in a no solution graphs,there is always the slopes but different y intercepts.A no solution graphs have parallel lines.
the equation y= 8x + 7 has the same slope as the equation y=8x - 30 which is 8 but as you can see different y-intercept 7 and -30.
