Answer:
7 inches
Step-by-step explanation:
The ratio of width to length of the known rectangle is 4 : 14 and this simplifies to 2 : 7.
The smaller similar rectangle will have the same ratio of 2 :7.
This can also be looked at another way. The second value in the ratio is 7/2 of the first value in the ratio and the first value is 2/7 of the second value.
Example:
7/2 * 2 = 7
Example:
2/7 * 7 = 2
Hello!
If there is a relationship between dependent and independent variables represented in a scatterplot, <span>The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.
The independent variable is the one that influences the dependent variable. If there is a relationship between them, it doesn't matter the direction of the points in the scatterplot, but the correlation coefficient.
If the points go up from left to right, the correlation is called direct correlation (increasing the value of the independent variable will increase the value of the dependent variable).
If the points go down from left to right, the correlation is called inverse correlation (increasing the value of the independent variable will decrease the value of the dependent variable)
Have a nice day!</span>

c
Step-by-step explanation:
From the question we are told that
The price per square foot of a floor tile is
The cost of shipping is
The current length of the square bathroom is x = 10 ft
The new length is
Generally the equation representing the cost of the square tile is mathematically represented as
Generally the average rate of change of cost is mathematically represented as
Generally the cost for flooring a 12 feet square bathroom is mathematically represented as
=>
Generally the cost for flooring a 10 feet square bathroom is mathematically represented as
=>
So
=>
Generally the instantaneous rate of change of cost is obtained by the differentiating the cost function as follows
So the instantaneous rate of change of cost at length 10 feet is mathematically represented as
=>
Generally given that the new cost function is
Now the instantaneous rate of change of cost will now be
So the instantaneous rate of change of cost at length 10 feet is mathematically represented as
=>
