Answer:
1. rational
2. rational
3. rational
4. not rational
5. not rational
Step-by-step explanation:
Given equation of line y=0.25x-7.
On comparing given equation with slope-intercept form y=mx+b.
We get m=0.25.
0.25 could be written 25/100 in simplest fractions 1/4.
Line are perpendicular.
Therefore, slope of the perpendiular line would be reciprocal and opposite in sign of the given slope of the line.
Reciprocal of 1/4 is 4 and opposite of sign of 4 would be -4.
So, the slope of the required line is m=-4.
We are given a point (-6,8).
Applying point-slope form, we get
y-y1=m(x-x1)
y-8 = -4(x- (-6))
y-8 = -4(x+6)
y-8 = -4x -24.
Adding 8 on both sides, we get
y-8=8 = -4x -24+8
y=-4x-16.
Therefore, the equation y=-4x-16 is perpendicular to the given eqution of line.
Answer:
19.42 ft
Step-by-step explanation:
c^2 = a^2 + b^2
c^2 = 16^2 + 11^2
c^2 = 256 + 121
c = √377 = 19.416
Answer:
the third one
Step-by-step explanation:
........
Answer:
The table must be Event vs Number of days.
Then you can write the table as:
In this way you have your information organized. Whit onle a look at the table you can see the number of days that had a temperature above 60°f, below 60°f and the sunny days.
