If f(x)=3x3+5x2-4, then what is the remainder when f(x) is divided by x-1
Fed [463]

Answer:

<h2>4</h2>

Step-by-step explanation:

If you divide a polynomial f(x) by a linear binomial (x - q), then a remainder is equal to f(q).

We have the polynommial:

f(x)=3x^3+5x^2-4

and the linear binomial:

x-1\to q=1

Calculate f(1)  <em>/substitute x = 1/:</em>

f(1)=3(1)^3+5(1)^2-4=3(1)+5(1)-4=3+5-4=4

Anit [1.1K]

Probability helps us to know the chances of an event occurring. The probability of choosing a black marble from the bowl is 0.2917.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

Probability=(Desired Outcomes)/(Total Number of possible outcomes)

The total number of marbles in the bowl is 24, while it contains 6 white, 8 blue, 7 black and 3 red. Therefore, the probability of choosing a black marble from the bowl is,

P(Black marble) = Number of black marble/Number of total Marble

P(Black Marble) = 7/24 = 0.2917

Hence, the probability of choosing a black marble from the bowl is 0.2917.

What is the slope of the line threw (-9,6) and (-3, 9)
boyakko [2]

The slope is the change in Y over the change in X.


(-9,6) is X1 and Y1.

(-3,9) is X2 and Y2.


Slope = Y2-Y1 / X2-X1


Slope = 9 - 6 / -3 - (-9)


Slope = 3/6 = 1/2


The slope = 1/2
