Answer:
f(10) = - 183
Step-by-step explanation:
To evaluate f(10), substitute x = 10 into f(x) , that is
f(10) = - 2(10)² + 17 = - 2(100) + 17 = - 200 + 17 = - 183
f(10)=-217
F(10)=-2*10^2 + 17= -2*100+17= -200+17=-217
5, -7
multiplying by 1.44 is the same as increasing by 44%
this is because 44+100 divided by 100 is 1.44
divide 6000 by 3
6000 / 3 = 2000
so he can do 2000 sq ft per hour
