c is the anser
Step-by-step explanation:
Answer:
Equation is;
(D/8) + (D/4) = 1600
D = 4266.67 ft
Step-by-step explanation:
We are told that the bee flies at a rate of 8ft/sec directly to a flowerbed from its hive. Thus,
speed during this stage is; v1 = 8ft/sec
Time during this stage is; t1
The bee stays at the flower bed for 1200 seconds.
Thus, time at this stage is; t2 = 1200 s
It flies directly back to the hive at 4ft/sec.
Speed at this stage; v2 = 4 ft/s
Time at this stage; t3
We are told that it was away for a total of 2800 seconds.
Thus; t1 + t2 + t3 = 2800
Since t2 = 1200 s, then;
t1 + 1200 + t3 = 2800
t1 + t3 = 2800 - 1200
t1 + t3 = 1600
Now, during time t1, the speed was 8ft/sec, since distance is equal to speed × time, then we have;
D = 8t1
t1 = D/8
During time t3, the speed was 4ft/sec. Thus; D = 4t3
t3 = D/4
Thus,since t1 + t3 = 1600
Then;
(D/8) + (D/4) = 1600
Multiply through by 8 to get;
D + 2D = 1600 × 8
3D = 12800
D = 12800/3
D = 4266.67 ft
Answer:
The equation of the line through the points (-5, 2) and (-2, 6) is 
.
Step-by-step explanation:
The point-slope form of the equation of the line is defined by this formula:
(1)
Where:
- Independent variable.
- Dependent variable.
- Slope.
, 
- Coordinates of the first point.
In addition, the slope of the line can be determined in terms of two distinct points:
(2)
Where 
, 
are the coordinates of the second point.
If we know that 
, 
, 
and 
, then the equation of the line is:
The equation of the line through the points (-5, 2) and (-2, 6) is .
The correct answer is A) Talking . Hope this helps.
Combine like terms on left side:
(5f-3f)+(4-2)=2f-2
2f+2=2f-2 subtract 2 from both sides
2f=2f-4 subtract 2f from both sides
0=-4
Since the above in not true,
5f+4-3f-2 does not equal 2f-2 for any value of f....
