Please help me with this math!
wel

Answer:

Please check the explanation.

Step-by-step explanation:

Given the polynomial function

f\left(x\right)\:=x^3+2x^2-16x-32

Let us determine the factors by solving

\:\left0\right\:=x^3+2x^2-16x-32\:

\left(x+2\right)\left(x+4\right)\left(x-4\right)=0

Using the zero factor principle:

if  ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)

x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0

Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.

Therefore,

YES

  • (x+2)
  • (x+4)
  • (x-4)

And (x-2) (x+6) are not the factors of the polynomial function.

Therefore,

YES

  • (x-2)
  • (x+6)

The graph shows the volume of oil (L litres) in a tank at time t seconds. a)find the gradient of the graph b)explain what this g
Alisiya [41]

Answer/Step-by-step explanation:

a. Using two points on the line (0, 2) and (4, 12), find the gradient:

Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5

Gradient = 2.5

b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.

i.e. 2.5 litres per second

c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.
