1. 21 peanuts per minute
2. 9 texts per minute
3. 28 pages per hour OR half a page per minute
4. The first option is the cheapest. You can find what one ounce costs for each barrel by dividing the cost by the total ounces.
So she walks at least 3 times.The distance is 600 meters
So 600·3=1800 meters= 1 kilometers and 800 meters-she going in the single day.
Answer:
Fill in the following tables, using the equations.
Cost of owning and operating the vehicles
Vehicle 0 1 2 3 4 5 6
Van $20,523 $23,723 $26,923 $30,123 $33,323 $36,523 $39,723
Car $23,540 $25,990 $28,440 $30,890 $33,340 $35,790 $38,240
How much does each vehicle cost initially?
- Van costs $20,523
- Car costs $23,540
How much does each cost to operate for one year?
- Van costs $3.200
- Car costs $2,450
Which one initially costs less?
Which one will cost less over the six years?
When do they cost about the same?
- year 4: van accumulated costs $33,323 and car accumulated costs = $33,340
Answer:
<u>first graph:</u>
function.
Not one-one
onto
<u>Second graph:</u>
Function
one-one
not onto.
Step-by-step explanation:
We know that a graph is a function if any vertical line parallel to the y-axis should intersect the curve exactly once.
A graph is one-one if any horizontal line parallel to the x-axis or domain should intersect the curve atmost once.
and it is onto if any horizontal line parallel to the domain should intersect the curve atleast once.
Hence, from the <u>first graph:</u>
if we draw a vertical line parallel to the y-axis then it will intersect the graph exactly once. Hence, the graph is a function.
But it is not one-one since any horizontal line parallel to the domain will intersect the curve more than once.
But it is onto, since any horizontal line parallel to the domain will intersect the curve atleast once.
<u>Second graph</u>
It is a function since any vertical line parallel to the co-domain will intersect the curve exactly once.
It is not one-one since any horizontal line parallel to the x-axis does not intersect the graph atmost once.
It is not onto, since any horizontal line parallel to the domain will not intersect the curve atleast once.
