Answer:

(x-4) is not a factor of f(x)=x³-2x²+5x+1

Step-by-step explanation:

Uding the remainder theorem,(x-4) is a factor if the remainder is 0

Plug in x=4

(4)³-2(4)²+5(4)+1

64-32+20+1

64-53

Please help me with these?? Work needs to be shown.
Y_Kistochka [10]

Answer:

Step-by-step explanation:

7) Area = 615.75 sq. km

πr² = 615.75

3.14*r² = 615.75

r² = 615.75/3.14 = 196

r = √196

r = 14 km

8) circumference = 15.71 yards

πd = 15.71

3.14*d = 15.71

d = 15.71/3.14  = 5 yards

9)Area = 415.48 sq.inches

πr² = 415.48

3.14*r² = 415.48

r² = 415.48/3.14 =  132.31

r = √132.31

r = 11.5 inches

diameter = 11.5*2 = 23 inches

Differentiate y=8x-3
Alexandra [31]

Answer:

dy/dx=8

Step-by-step explanation:

note this differentiating a constant you get zero for that of a function like 8x you would use the index or power of x to multiply the coefficient of the x after substrate 1 from the power of the x putting that in writing for the above question we get

y'=dy/dx=(8*1)x^(1-1) - 0

y'=dy/dx=8x^0

y'=dy/dx=8
