what is the behavior of the graph y =-x^3-5x^2-3+9 at each of its zeros
The behavior of the graph of the function y = -x^3 - 5x^2 - 3x + 9 at each of its zeros is as follows:
At x ≈ -4.919 and x ≈ -0.488, there are local minima.
At x ≈ 1.752, there is a local maximum.
Let's analyze the behavior of the graph of the function y = -x^3 - 5x^2 - 3x + 9 at each of its zeros in more detail.
To find the zeros of the function, we need to solve the equation -x^3 - 5x^2 - 3x + 9 = 0.
To simplify the calculations, let's use a numerical method like the Newton-Raphson method to approximate the zeros. We'll start with initial guesses and iteratively refine them to improve the accuracy of the solutions.
Initial guess: x_0 ≈ -5
Applying the Newton-Raphson method:
x_1 = x_0 - f(x_0) / f'(x_0)
where f(x) = -x^3 - 5x^2 - 3x + 9
f'(x) = -3x^2 - 10x - 3 (derivative of f(x))
x_1 = -5 - (-5^3 - 5(-5)^2 - 3(-5) + 9) / (-3(-5)^2 - 10(-5) - 3)
≈ -4.919
Initial guess: x_0 ≈ -1
Applying the Newton-Raphson method:
x_1 = x_0 - f(x_0) / f'(x_0)
x_1 = -1 - (-1^3 - 5(-1)^2 - 3(-1) + 9) / (-3(-1)^2 - 10(-1) - 3)
≈ -0.488
Initial guess: x_0 ≈ 2
Applying the Newton-Raphson method:
x_1 = x_0 - f(x_0) / f'(x_0)
x_1 = 2 - (2^3 - 5(2)^2 - 3(2) + 9) / (-3(2)^2 - 10(2) - 3)
≈ 1.752
After iterating through the Newton-Raphson method, we approximate the zeros as follows:
x ≈ -4.919
x ≈ -0.488
x ≈ 1.752
Now, let's analyze the behavior of the graph at each zero:
x ≈ -4.919:
When x is close to -4.919, y is close to zero. Since the coefficient of the leading term (-x^3) is negative, as x approaches -4.919 from the left side, the graph of the function will be decreasing. As x approaches -4.919 from the right side, the graph will be increasing. Therefore, the behavior of the graph near x ≈ -4.919 is a local minimum.
x ≈ -0.488:
When x is close to -0.488, y is close to zero. Similarly, as x approaches -0.488 from the left side, the graph will be decreasing, and as x approaches -0.488 from the right side, the graph will be increasing. Therefore, the behavior of the graph near x ≈ -0.488 is also a local minimum.
x ≈ 1.752:
When x is close to 1.752, y is close to zero. In this case, as x approaches 1.752 from the left side, the graph will be increasing, and as x approaches 1.752 from the right side, the graph will be decreasing. Therefore, the behavior of the graph near x ≈ 1.752 is a local maximum.

A very strong wind is blowing over some mountains. Bella, the eagle, begins to fly home to bring food to the hatchlings in the nest. For every five hundred fifty meters Bella flies, she is blown back fifty meters by the wind. Bella's nest is five kilometers away. If bella flies five hundred fifty meters in one minute and begins at eleven thirty in the morning, what time will bella reach the nest?
Answer:
11:40 in the morning
Step-by-step explanation:
Given that for every 550 m, Bella the eagle flies, she is blown back fifty meters by the wind. Her nest is 5 km and she flies 550 m in 1 minutes.
Therefore for Bella to reach her nest which is 5 km (5000 m) away, the required distance (d) she needs to travel is:
d - (d/550)50 = 5000
d - 50d/550 = 5000
500d / 550 = 5000
d = (550 * 5000) / 500 = 5500
d = 5500 m = 5.5 km
speed = distance / time = 550 m / 1 minutes = 550 meters per minute
The time t required to cover 5500 m is:
speed = distance / time
550 meters per minute = 5500 m / t
t = 5500 m / 550 meters per minute
t = 10 minutes
If Bella lives at 11:30 am in the morning and then travels for 10 minutes to reach her nest, the time Bella will reach her nest is 11:40 am

Answer:
Vertex means the highest or lowest coordinate in a parabola (and also absolute value)
Here we see the lowest point is (-2,0), so the vertex is (-2,0)
A standard quadratic equation is written as a(x-h)^2+k
h and k are the vertex coordinate h is x and k is y
so by finding the vertex we found that h = -2 and k = 0
so you plug it in
a(x-(-2))^2+0=y
a(x+2)^2=y
when finding a, you take a random point in the graph and plug it in and solve it
lets take (-1,1)
so its a(-1+2)^2 = 1
a(1)^2 = 1
a=1
so the equation will be 1(x+2)^2 = y or (x+2)^2=y (don't need to write the 1)

In an Economics course, the correlation between the students' total score prior to the final exam and
their final exam score is r = 0.60. The pre-exam totals for all students in the course have mean 280
points and standard deviation 30 points. The final exam scores have mean 75 points and standard
deviation 8 points.
4. Find the equation of the least-squares regression line for predicting a final exam score from a
student's pre-exam total.
5.
Interpret the slope in context.
6.
Interpret the y-intercept in context.
7.
Calculate the fraction of variability, R?.
8.
Interpret R? in context.
Answer:
See below for answers and explanations
Step-by-step explanation:
Problem 4:
The line of regression is [tex]\hat y = a+bx[/tex] where:
[tex]a=\overline y-b \overline x[/tex]
[tex]b=\frac{r*s_y}{s_x}[/tex]
We are given that [tex]\overline y=75[/tex], [tex]s_y=8[/tex], [tex]\overline x=280[/tex], [tex]s_x=30[/tex], and [tex]r=0.60[/tex], therefore our slope, [tex]b[/tex], is:
[tex]b=\frac{r*s_y}{s_x}[/tex]
[tex]b=\frac{(0.60)(8)}{30}[/tex]
[tex]b=0.16[/tex]
Therefore, the slope of the regression line is 0.16, which can be used along with the values of [tex]\overline y[/tex] and [tex]\overline x[/tex] to find the constant [tex]a[/tex]:
[tex]a=\overline y-b \overline x[/tex]
[tex]a=75-(0.16)(280)[/tex]
[tex]a=30.2[/tex]
This means our final regression line is [tex]\hat y = 30.2 + 0.16x[/tex]
Problem 5:
The slope, [tex]b=0.16[/tex], means that for every 1 point earned for a student's pre-exam total, their final exam score will increase by 0.16 points for each point they earned on the pre-exam.
Problem 6:
The y-intercept (or constant), [tex]a=30.2[/tex], means that if a student's pre-exam total were 0, then they would expect to get a 30.2 on the final exam.
Problem 7:
[tex]R^{2}=(0.60)^{2}=0.36=36\%[/tex]
Problem 8:
The fraction of variability (aka. coefficient of determination), [tex]R^2[/tex], means that a certain proportion (or percentage) of the variance in the response variable can be explained by the explanatory variable. In context, this means that 36% of the variance in final exam scores can be explained by the pre-exam scores.

Find the second, fourth, and eleventh terms of the sequence A(n) = 5 + (n - 1)(-3)
Answer:
2nd: 2
4th: -4
11th: -25
Step-by-step explanation:
When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:
A(2) = 5 + (2 - 1)(-3)
A(2) = 5 + (1)(-3)
A(2) = 5 - 3
A(2) = 2
To get the 4th term you substitute in 4:
A(4) = 5 + (4 - 1)(-3)
A(4) = 5 + (3)(-3)
A(4) = 5 - 9
A(4) = -4
And we do the same for the 11th term:
A(11) = 5 + (11 - 1)(-3)
A(11) = 5 + (10)(-3)
A(11) = 5 - 30
A(11) = -25
