Answer:
y = 1/2x +4
Step-by-step explanation:
You are given the slope (m) of the line and a point, and asked for slope-intercept form:
y = mx +b . . . . . . . line with slope m and y-intercept b
The value of the intercept, b, can be found from the point by rearranging this equation to ...
b = y -mx
b = 1 -1/2(-6) = 4 . . . . using x=-6, y=1
Then the equation of the line with m=1/2 and b=4 is ...
y = 1/2x +4
Answer:
the answer is c none of the above
Answer:
The radius is decreatsing at a rate 0.78 cm per second.
Step-by-step explanation:
We are given the following in the question:

Instant radius,r = 2 cm
Instant length,l = 9cm
The radius of the cylinder decreases.
Volume of cylinder =

Since the volume of the cylinder does not changes, we can write:

Rate of change of volume:

Puttiung values, we get

Thus, the radius is decreatsing at a rate 0.78 cm per second.
Answer:
The practical domain of the function is the set of all integers from 1 to 5, inclusive.
Step-by-step explanation:
It is given the initial number of sheets of paper is 45.
A store has 5 reams of paper, and each ream contains 500 sheets of paper.
Let f(x) represent the number of sheets after purchasing x reams.

Domain is the set of input. In other words domain is the set of x-values.
Since number of reams can not be a negative or fraction value, therefore, the domain of the function is {1,2,3,4,5}.
Andre needs to buy more sheets, so number of reams of paper can not be 0.
Thus, the practical domain of the function is the set of all integers from 1 to 5, inclusive.
Yes, all fractions could be written in a repeating decimal.
