Answer:  The correct option is (a) 2x^2+3x-5.

Step-by-step explanation:  We are given to find the quotient in the following division :

Q=\dfrac{2x^3-3x^2-14x+15}{x-3}.

To find the quotient, first we will try to factorize the numerator and then we will try to divide by the denominator.

We have

Q\\\\\\=\dfrac{2x^3-3x^2-14x+15}{x-3}\\\\\\=\dfrac{2x(x-3)+3x(x-3)-5(x-3)}{x-3}\\\\\\=\dfrac{(x-3)(2x^2+3x-5)}{(x-3)}\\\\=2x^2+3x-5.

Thus, the required coefficient is 2x^2+3x-5.

Option (a) is CORRECT.

What is the value of the power a if 5 to the power of a is equal to 1/125
padilas [110]

First of all, you should know/notice that

125=5^3

You should also know how negative exponents work:

a^{-m}=\dfrac{1}{a^m}

So, if you wanted

5^x=125

the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:

5^{-3}=\dfrac{1}{5^3}=\dfrac{1}{125}

Find in degrees the numeric value of the acute angle of rotation that eliminates the product term from the equation 7x2+24xy−34x
lutik1710 [3]

Rotating the graph of Ax^2+Bxy+Cy^2+Dx+Ey+F=0 with B\ne0 counterclockwise by \theta eliminates the xy term, where \cot2\theta=\frac{A-C}{B}. Plugging in, we have \cot2\theta=\frac{7}{24}, since C=0. Solving, we have \theta=\frac{1}{2}\cot^{-1}(\frac{7}{24})\approx\boxed{36.9^\circ}.

How to cross multiple 3/5 by 10
Vika [28.1K]

Here is you're answer:

In order to cross multiply you have to multiply the numerator and denominator of the first fraction by the bottom number of the second fraction and see if the equation is still true:

  • \frac{3}{5} \times 10
  • \frac{3}{5} \times \frac{10}{1}
  • 3 \times 1 = 5 \times 10
  • Solve if you like:
  • 3 \times 1 = 3
  • 5 \times 10 = 50
  • = \frac{4}{50}

Therefore you're answer is "3 × 1 = 5 × 10."

Hope this helps!
