Given that f(x)=8x^3-22x^2-4 and g(x)=4x-3

Question says to find f of x over g of x which simply means divide value of f(x) by value of g(x)

Dividing them gives:

\frac{f(x)}{g(x)}=\frac{8x^3-22x^2-4}{4x-3}

Denominator is already in factored form which can't divide numerator means it can't be simplified more.

Hence final answer is \frac{f(x)}{g(x)}=\frac{8x^3-22x^2-4}{4x-3}.

other part of question is not clear so i will skip them.

Answer:

The correct answer is the first one.

Step-by-step explanation:

We have the functions f(x) = 8x^3-22x^2-4 and g(x) = 4x-3. Then, the fraction is

\frac{f(x)}{g(x)} = \frac{8x^3-22x^2-4}{4x-3}.

If we want to give a ‘‘simplified’’ expression for this quotient we must do a a division of polynomials. The algorithm is the analogue for the division of integers. Attached there is an image of the procedure.

After the completion of the division algorithm we obtain

\frac{f(x)}{g(x)} = \frac{(4x-3)(2x^2-4x-3)-13}{4x-3} = 2x^2-4x-3 - \frac{13}{4x-3}.

The area of a rectangle is 64 square centimeters. The rectangle is 4 centimeters wide. How long is the rectangle.
VLD [36.1K]
The Area is the width<span> times the </span>height<span>: A = w x h;
Then, 64 = w x h;
h = 4 + w;
64 = 4w  + w^2;
w^2 + 4w - 64 = 0;
We solve this equation: w1 </span>≈ 6,24 > 0 (okay); w2 ≈ - 10,24 < 0 (not okay);
<span>Finally, h1 </span>≈ 10,24;<span>

The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 80% of planted seeds will germinate. Suppose t
olga nikolaevna [1]

The Probability of that more than 7 of them germinate is 0.2948.

<h3>What is Probability?</h3><h3>Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.</h3>

We are to determine the probability that more than 7 of 10 seeds (i.e. 8, 0r 9 0r 10) germinate.

The probability that all 10 seeds germinate is equal 0.80¹⁰= 0.1073 = 10.73%.

The probability that only the first (only the second, etc ) seed does not germinate is equal 0.20 X 0.80⁹= 0.0268 = 2.68%.

The probability that 6 seeds germinate is the sum of the probabilities that only the first seed does not germinate, only the second one does not germinate, etc, and equals to 10 X 0.0268  = 0.268 = 26.8%.

The total probability that more than 7 of 10 seeds germinate is the sum of the probabilities that 10 seeds germinate and that 7 seeds germinate, i.e. 2.68 % + 26.8 % = 29.48 %.

Thus, The Probability of that more than 7 of them germinate is 0.2948.
