Which of the following graphs is a polynomial function with x-intercepts of (-2, 0), (0, 0), and (3, 0)?
Sergio [31]

Answer:

The intercepts of the third degree polynomial corresponds to the zeros of the equation

y = d*(x-a)*(x-b)(x-c)

Where a, b and c are the roots of the polynomial and d an adjustment coefficient.

y = d*(x+2)*(x)*(x-3)

Lets assume d = 1, and we get

y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x

We graph the equation in the attached file.

Solve the equation using square roots. Write your answer in simplest form.<br> Question in picture
GalinKa [24]

Answer:

The solutions to the quadratic equation involving square roots are:

x=2\sqrt{7}i+8,\:x=-2\sqrt{7}i+8

Step-by-step explanation:

Given the equation

\frac{1}{4}\left(x-8\right)^2+8=1

subtract 8 from both sides

\frac{1}{4}\left(x-8\right)^2+8-8=1-8

\frac{1}{4}\left(x-8\right)^2=-7

\left(x-8\right)^2=-28

\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}

solving

x-8=\sqrt{-28}

x-8=\sqrt{-1}\sqrt{28}

x-8=\sqrt{28}i       ∵ \sqrt{-1}=i

x=2\sqrt{7}i+8

similarly solving

x-8=-\sqrt{-28}

x-8=-2\sqrt{7}i

x=-2\sqrt{7}i+8

Therefore, the solutions to the quadratic equation involving square roots are:

x=2\sqrt{7}i+8,\:x=-2\sqrt{7}i+8

A brand of cereal had 1.2 milligrams of iron per serving. Then they changed their recipe so they had 1.8 mg of iron per serving.
Anvisha [2.4K]

Using it's concept, it is found that the percent increase in the amount of iron per serving was of 50%.

<h3>What is the percentage increase of a value?</h3>

It is given by the increase divided by the initial value, and subtracted by 100%.

In this problem:

  • The initial value is of 1.2 mg.
  • The increase was of 1.8 mg - 1.2 mg = 0.6 mg.

Hence the percent increase is given by:

P = 0.6/1.2 x 100% = 50%.
