Answer: $820
Step-by-step explanation:
Use a proportion
9.5/100 = 77.90/x
Multiply 77.90 times 100 and divide by 9.5, the answer is $820
Π/6+2πk
5π/6+2πk
you need to factor and use trig identities
F(x)=6x^4-10x^3+40x-50, plug 2 in for x
f(2)=6(2)^4-10(3)^3+40(2)-50
f(2)=12^4-30^3+80-50
f(2)=20735-27,000+80-50
f(2)=-6,235
