Answer:

Option (A) and (C).

Step-by-step explanation:

Prime polynomial can't be written as a product of lower degree polynomials.

(A)

8x^2-10x-3

=8x²-6x-4x-3

=2x(4x-3)-1(4x+3)

Here we can't write the polynomial as a product of lower degree.

Therefore it is a prime polynomial.

(B)

8x²+2x-3

=8x²+6x-4x-3

=2x(4x+3)-1(4x+3)

=(4x+3)(2x-1)

Therefore it is not a prime polynomial.

(C)

8x²-6x-3

Therefore it is a prime polynomial.

(D)

8x²+23x-3

=8x²+24x-x-3

=8x(x+3)-1(x+3)

=(x+3)(8x-1)

Therefore it is not a prime polynomial.

Answer:

48%

Step-by-step explanation:

P (not getting a speckled rock) = 12/18 = 2/3

P (not getting a green rock) = 13/18

2/3 * 13/18 = 26/54 = 13/27 ≈ 48%

Solve the equation using the Zero­Product Property. 6x(3x + 1) = 0
neonofarm [45]
   
\displaystyle  \\ 
6x(3x + 1) = 0 \\  \\ 
\Longrightarrow ~~ 6x = 0~~\texttt{or}~~3x+1=0 \\  \\ 
6x = 0 ~~\Longrightarrow ~~ x_1 =  \frac{0}{6} = \boxed{0} \\  \\ 
3x+1 = 0 ~~\Longrightarrow ~~ 3x = -1  ~~\Longrightarrow ~~ x_2 =  \frac{-1}{3} = \boxed{-\frac{1}{3}} \\  \\

Answer:

$2000 was invested at 5% and $5000 was invested at 8%.

Step-by-step explanation:

Assuming the interest is simple interest.

<u>Simple Interest Formula</u>

I = Prt

where:

  • I = interest earned.
  • P = principal invested.
  • r = interest rate (in decimal form).
  • t = time (in years).

Given:

  • Total P = $7000
  • P₁ = principal invested at 5%
  • P₂ = principal invested at 8%
  • Total interest = $500
  • r₁ = 5% = 0.05
  • r₂ = 8% = 0.08
  • t = 1 year

Create two equations from the given information:

\textsf{Equation 1}: \quad \sf P_1+P_2=7000

\textsf{Equation 2}: \quad \sf P_1r_1t+P_2r_2t=I\implies 0.05P_1+0.08P_2=500

Rewrite Equation 1 to make P₁ the subject:

\implies \sf P_1=7000-P_2

Substitute this into Equation 2 and solve for P₂:

\implies \sf 0.05(7000-P_2)+0.08P_2=500

\implies \sf 350-0.05P_2+0.08P_2=500

\implies \sf 0.03P_2=150

\implies \sf P_2=\dfrac{150}{0.03}

\implies \sf P_2=5000

Substitute the found value of P₂ into Equation 1 and solve for P₁:

\implies \sf P_1+5000=7000

\implies \sf P_1=7000-5000

\implies \sf P_1 = 2000

$2000 was invested at 5% and $5000 was invested at 8%.
