So the radius is 7 inch which is given
Use the formula for the circumference which is 2xpiXradius
2x3.1415x7=44 to nearest integer
Answer: The value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500 is $417
Profit=372.6+17.2 (advertising dollars)
Advertising dollars=$1,020
Predicted Profit=372.6+17.2 (1,020)→
Predicted Profit=372.6+17,544→
Predicted Profit=$17,916.6
Residual=Predicted Profit-Profit→
Residual=$17,916.6-$17,500→
Residual=$416.6
Rounded to the nearest integer:
Residual=$417
Answer: The value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500 is $417
F(x)=2x²+5√(x-2)
f(3)=2(3)²+5√(3-2)
= 2 (9) + 5√1
= 18 + 5
= 23.
