Is the polynomial prime? <br> 7x2-35x+2x-10

wolverine [178]

The given polynomial is not a prime polynomial.

Given the polynomials, we have to choose the polynomial which is prime.

A polynomial with integer coefficients that cannot be factored into lower degree polynomials is Prime polynomials.

$7x^2-35x+2x-10$

$7x^2-33x-10$

$\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}$

<h3>What is the formula for the quadratic roots?</h3>

$\quad x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$\mathrm{For\:}\quad a=7,\:b=-33,\:c=-10$

$x_{1,\:2}=\frac{-\left(-33\right)\pm \sqrt{\left(-33\right)^2-4\cdot \:7\left(-10\right)}}{2\cdot \:7}$

$x_{1,\:2}=\frac{-\left(-33\right)\pm \:37}{2\cdot \:7}$

$x_1=\frac{-\left(-33\right)+37}{2\cdot \:7},\:x_2=\frac{-\left(-33\right)-37}{2\cdot \:7}$

$x=5,\:x=-\frac{2}{7}$

Therefore the factor is (x-5) and (7x+2).

can be factored

∴ not a prime polynomial.

Joesphine scored 95, 84, and 87 on three math tests. She wants her average score for 5 tests to be at least 90.

attashe74 [19]

Answer:

The answer for part B is I think 92 and 92. And for part A she could get 97 and 97 as the test average would be 92.

Step-by-step explanation:

I kinda explained it in the answer yeah but I hope that helps.

Which of the following angles is coterminal with -4pi/3?<br><br> -2pi/3<br> -pi/3<br> pi/3<br> 2pi/3

PolarNik [594]

Coterminal angles are angles that end in the same position on a unit circle.

We can find angles that are coterminal to -4pi/3 by adding and subtracting 2pi.

-4pi/3 + 2pi = 2pi/3

The answer is 2pi/3
