R(x)=x^3+5x^2-2x-24 Plot the zero(s) of the function.
nevsk [136]

:) Brainliest pls?

Answer:

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Step-by-step explanation:

I'll find the zeros, aka x-intercepts, and you could probably graph them.

To find the zeros, let's factor this polynomial:

r(x) = (x - 2)(x^2+7x+12)

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

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Xavier can swim at a constant speed of 5/3 meters/second.
koban [17]

Answer:

Step-by-step explanation:

Well we can find how far he travels in 55 seconds if he swims at constant speed of 5/3 meters.

5/3 times 55 = approx. 91.66 meters

Therefore Xavier will not quality for the national Swim Meet because he didn't swim 100 meters in 55 seconds

Pls help
boyakko [2]

Answer:

4. C) (3, -2)

3. B) 9,6 = the number of points you would increase each hour of studying; 65,8 = your score if you studied 0 hours

2. B) The events have a strong positive linear correlation.

1. C) Find the slope using the slope formula:

\frac{y_2 - y_1}{x_2 - x_1}

Step-by-step explanation:

4. (−7, 10) → 10 = 7 + 3 ☑

(−1, 4) → 4 = 1 + 3 ☑

(0, 3) → 3 = 0 + 3 ☑

(3, −2) → −2 ≠ −3 + 3; 0 ☒

3. You obviously have to plug "0" in for x to get your initial value of 65,8, which represents the minimum value of points you would receive if you never were to study, and of course, the 9,6 is the average score increased for every hour studied.

2. The correlation coefficient is 0,02, which is positive, so this would be the obvious choice.

1. You CANNOT write a linear equation without FIRST finding the rate of change [slope]. You will ALWAYS need the rate of change in order to write any linear equation.

I am joyous to assist you anytime.
