Answer:
The function in Python is as follows:
def d2x(d, x):
if d > 1 and x>1 and x<=9:
output = ""
while (d > 0):
output+= str(d % x)
d = int(d / x)
output = output[::-1]
return output
else:
return "Number/Base is out of range"
Explanation:
This defines the function
def d2x(d, x):
This checks if base and range are within range i.e. d must be positive and x between 2 and 9 (inclusive)
if d >= 1 and x>1 and x<=9:
This initializes the output string
output = ""
This loop is repeated until d is 0
while (d > 0):
This gets the remainder of d/x and saves the result in output
output+= str(d % x)
This gets the quotient of d/x
d = int(d / x) ----- The loop ends here
This reverses the output string
output = output[::-1]
This returns the output string
return output
The else statement if d or x is out of range
<em> else:</em>
<em> return "Number/Base is out of range"</em>

Answer:
D. Refrigerants
Explanation:
In the United States of America, the agency which was established by US Congress and saddled with the responsibility of overseeing all aspects of pollution, environmental clean up, pesticide use, contamination, and hazardous waste spills is the Environmental Protection Agency (EPA). Also, EPA research solutions, policy development, and enforcement of regulations through the resource Conservation and Recovery Act .
The Clean Air Act Amendments of 1990 prohibit service-related releases of all refrigerants such as R-12 and R-134a. This ban became effective on the 1st of January, 1993.
Refrigerants refers to any chemical substance that undergoes a phase change (liquid and gas) so as to enable the cooling and freezing of materials. They are typically used in air conditioners, refrigerators, water dispensers, etc.
You never said what language so I used C
#include <stdio.h>
<span>int main () { </span>
<span> int a; </span>
<span> for( a = 3; a > 0; a-- ){ </span>
<span> printf("%i \n", a); }</span>
<span> printf(" Blast OFF !!!\n"); </span>
<span>return 0; </span>
<span>}</span>
