Yes, it is reasonable. If a painter paints a fourth of a room in a fourth of a day, well that means in two-fourths of a day he would paint two-fourths of a room. Same for three fourths and four fourths, which is equal to one day. If he or she can paint one room in one day, it'd be reasonable to say that he can paint 7 rooms in 7 days.
Answer:
± 3
Step-by-step explanation:
h(x) = sqrt( 2x+1)
h(4) = sqrt(2*4+1)
= sqrt(8+1)
= sqrt(9)
± 3
When any lines are parallel that means they have the same slope so the slope of the red line would also have a slope of -3/7
1: That if you divide it by 3 you can get 33.
2. It's one away from 100.
3. Some factors are 1, 3, 9, and 11.
Answer: After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
Step-by-step explanation:
Given: Sharon is conducting research on two species of birds at a bird sanctuary.
The number of birds of species A is represented by the equation below,where S represents the number of birds, x years after beginning her research.

The number of birds of species B is represented by the equation below,where S represents the number of birds, x years after beginning her research.

To plot the above function, first find points by which they are passing.
For species A, At x=0 , 
At x=2 , 
Similarly find more points and plot curve on graph.
For species A, At x=0 , 
At x=2 , 
Plot a line with the help of these two points.
Now, from the graph the intersection of curve (for A) and line (for B) is at (7,140) which tells that After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
