The answer is 11 \frac{5}{6} inches

Step 1. Subtract length of the door from the width of the door:
27 \frac{1}{2} - 9 \frac{3}{4} =  \frac{55}{2} - \frac{39}{4} =\frac{110}{4} - \frac{39}{4}= \frac{71}{4}

Step 2. You want the same space to be on each side of the bar. So, divide the difference from step 1 by 2:
\frac{71}{4} : 2 = \frac{71}{4} :  \frac{2}{1} =\frac{71}{4} * \frac{1}{2}= \frac{71}{6} =  \frac{66+5}{6}= \frac{66}{6}+ \frac{5}{6}=11 \frac{5}{6}

Answer:

8\frac{7}{8}    

Step-by-step explanation:

It has been given that you want to place 9\frac{3}{4} inch towel bar in the center of a door that is 27\frac{1}{2} wide.

First of all, we will find the total space left on both sides of towel bar by subtracting 9\frac{3}{4} from 27\frac{1}{2}.    

27\frac{1}{2}-9\frac{3}{4}  

\frac{27*2+1}{2}-\frac{9*4+3}{4}    

\frac{54+1}{2}-\frac{36+3}{4}

\frac{55}{2}-\frac{39}{4}

Let us have a common denominator.

\frac{55*2}{2*2}-\frac{39}{4}

\frac{110}{4}-\frac{39}{4}

\frac{110-39}{4}

\frac{71}{4}

Now, we will divide \frac{71}{4} by 2 to find the space left on each side of the towel bar.

\frac{71}{4}\div 2

\frac{71}{4}\div \frac{2}{1}

By flipping the second fraction and multiplying by 1st fraction we will get,

\frac{71}{4}\times \frac{1}{2}

\frac{71}{8}

8\frac{7}{8}

Therefore, 8\frac{7}{8} inch of space will be on each side of the towel bar.

Answer:

  A. perhaps 0 to 7 days

  B. the radius in mm at the start of the study

  C. 0.114 mm/day

Step-by-step explanation:

A. It is always problematic to determine the reasonable domain for an exponential growth function. You can always limit the domain to the length of time for which the function is said to model the growth. It is difficult to say how much beyond that time period the exponential growth can be extrapolated, as most systems run into limits to growth.

Here, the base of the exponential term is 1.01 = 1 + 1%. This tells you the growth rate is 1% per day. The study concludes when the radius was 11.79/11.00 = 1.071818... ≈ 1 + 7.2% times the original size. That is, the study lasted approximately 7 days.

The question in part C has you look at the size on day 7, which is apparently the last day of the study. It is not clear that the model is at all useful beyond the end of the period it is intended to describe.

A reasonable domain for the growth function is 0 to 7 days.

__

B. The function gives the radius of the algae after d days. When d=0 (the y-intercept), the function gives the radius of the algae after 0 days. That is the meaning of the y-intercept is the initial radius of the algae (at the beginning of the study).

The y-intercept is always the "initial value", the value when the independent variable is zero. You have to look at the function definition to see what it is the initial value of.

__

C. The average rate of change is the difference in function values divided by the difference in time between them. Here, the attached table tells us that is ...

  (f(7) -f(2))/(7 -2) = (11.793 -11.221)/5 = 0.572/5 = 0.1144 . . . mm/day

The units of the "average rate of change" are the units of the slope of the curve on the graph: the y-axis units divided by the x-axis units. Here, that is mm/day.

Which equation shows the point slope form of the line that passes through (5,1) and has a slope of 1/2
arsen [322]

Answer:

3rd option, y-1 = \frac{1}{2} (x-5)

Step-by-step explanation:

To find out which option is correct, we can write the equation in point-slope form ourselves.  

Use the point-slope formula y-y_1 = m (x-x_1) to write the equation in point-slope form. Substitute the m, x_1, and y_1 for real values.

Since m represents the slope, substitute \frac{1}{2} in its place. Since x_1 and y_1 represent the x and y values of a point the line intersects, substitute the x and y values of (5,1) into the formula as well. Substitute 5 for x_1 and 1 for y_1. This gives the following equation:

y-1 = \frac{1}{2} (x-5)
