Answer:

the answer is C

Step-by-step explanation:

the answers would be x = 1 and x = -2/3.

Answer:

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

Step-by-step explanation:

The function with a graph that has a vertex 5 units horizontally to the right of the vertex of the graph of g(x) = (x + 2)^2 + 2 is f(x) = (x - 3)^2 + 2, which can be obtained by subtracting 5 from x + 2 to get x - 3 inside the parentheses of (x - 3)^2 and translating the vertex horizontally to (3, 2).

What the polynomial said when it sat down for dinner is "I've got a lot of roots" (sounds like "I've got a lot of fruits") as a polynomial equation can have multiple roots.

Polynomial equations are equations in which the variables and coefficients are combined using the mathematical operations of addition, subtraction, and multiplication, but not division by a variable.

The degree of a polynomial equation is determined by the highest power of the variable in the equation.

Polynomial equations can have one or more variables and are often used in mathematical modeling to represent real-world phenomena. The solutions to polynomial equations can be found by factoring, using the quadratic formula, or using numerical methods.

What is common ratio?

The common ratio between consecutive terms in a geometric sequence is constant. Let's denote this common ratio by 'r'. To find 'r', we can divide any term by the preceding term,

We have a chart table present in above figure and shows the sample informations for making a control chart. Now, control Limits are Calculated by:

For a Sample size, n = 10

A. For any number of monthly calls "x" greater than 200, Plan 1 is more economical than Plan 2.

The answer to part a means that if a customer expects to make more than 200 local calls per month, it is more economical for them to choose Plan 1 over Plan 2. For example, if a customer makes 250 local calls per month, Plan 1 would cost $28 while Plan 2 would cost $20 ($12 + $0.08 x 250), so Plan 1 would be the better choice for them. However, if a customer expects to make fewer than 200 local calls per month, then Plan 2 would be more economical for them, as they would pay less than $28 per month.

The break-even point is the number of monthly calls for which the total cost of Plan 1 is equal to the total cost of Plan 2.

for Identify two-dimensional (2-D)Figures and their positions.

2D stands for 2-dimensional. 2-dimensional shapes are flat and only have two dimensions: length and width. They include squares, rectangles, circles, triangles

Step-by-step explanation:

The probability that the random variable has a value between 0.1 and 3.3 is 0.0256. Option b is correct answer.

Since the area under the density curve represents the total probability, we need to find the area between the vertical lines at x = 0.1 and x = 3.3, and under the curve.

First, we need to find the y-coordinates of the two horizontal lines. The line passing through (0, 125) and (8, 125) is parallel to the x-axis, so it has a constant y-coordinate of 125. The line passing through (8, 0) and (8, 125) is parallel to the y-axis, so it has an undefined slope and is a vertical line.

Therefore, we do not need to find its y-coordinate.

Next, we need to find the equation of the density curve. Since it is a uniform density curve, the height of the curve is constant over its entire length.

To find the height, we need to find the total area under the curve, which is given by the rectangle formed by the vertical lines at x = 0 and x = 8, and the horizontal lines at y = 0 and y = 125.

The width of the rectangle is 8, and the height is 1/125 (since the total area is 1 and the width is 8). Therefore, the height of the curve is 1/125 over its entire length.

Now, we can find the area between the vertical lines at x = 0.1 and x = 3.3, and under the curve.

The width of this area is 3.3 - 0.1 = 3.2, and the height of the curve is 1/125. Therefore, the area is:

3.2 × (1/125) = 0.0256

Therefore, the probability that the random variable has a value between 0.1 and 3.3 is 0.0256.

Answer:

D

Step-by-step explanation:

y = x² - 4x - 5 → (1)

y = x - 9 → (2)

substitute y = x² - 4x - 5 into (2)

x² - 4x - 5 = x - 9 ( subtract x - 9 from both sides )

x² - 5x + 4 = 0 ← in standard form

(x - 1)(x - 4) = 0 ← in factored form

equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 4 = 0 ⇒ x = 4

substitute these values into (2) for corresponding values of y

x = 1 : y = 1 - 9 = - 8 ⇒ (1, - 8 )

x = 4 : y = 4 - 9 = - 5 ⇒ (4, - 5 )

The average rate of change of the function is:

a) f(x) = 12x^3 + 12 over the interval [5,7] is 1032.

b) f(x) = 12x^3 + 12 over the interval [-4,4] is 507.

a) To find the average rate of change of the function f(x)=12x^3 + 12 over the interval [5,7], follow these steps:

. Evaluate the function at the endpoints of the interval: f(5) and f(7).
  f(5) = 12(5)^3 + 12 = 1532
  f(7) = 12(7)^3 + 12 = 3596

. Subtract the function values: f(7) - f(5) = 3596 - 1532 = 2064.
. Subtract the x-values: 7 - 5 = 2.
. Divide the difference in function values by the difference in x-values: 2064 ÷ 2 = 1032.
So, the average rate of change of the function f(x) = 12x^3 + 12 over the interval [5,7] is 1032.

b) To find the average rate of change of the function f(x) = 12x^3 + 12 over the interval [-4,4], follow these steps:
. Evaluate the function at the endpoints of the interval: f(-4) and f(4).
  f(-4) = 12(-4)^3 + 12 = -2028
  f(4) = 12(4)^3 + 12 = 2028
. Subtract the function values: f(4) - f(-4) = 2028 - (-2028) = 4056.
. Subtract the x-values: 4 - (-4) = 8.
. Divide the difference in function values by the difference in x-values: 4056 ÷ 8 = 507.
So, the average rate of change of the function f(x) = 12x^3 + 12 over the interval [-4,4] is 507.

Step-by-step explanation:

We are given:

Sample size (n) = 35

Sample mean ($\bar{x}$) = 36 seconds

Population standard deviation ($\sigma$) = 8 seconds

Confidence level = 95%

We can find the margin of error using the formula:

Margin of Error = z*(σ/√n), where z is the z-score for the given confidence level, σ is the population standard deviation, and n is the sample size.

For a 95% confidence level, the z-score is 1.96 (from the z-table or calculator).

Putting the values in the formula, we get:

Margin of Error = 1.96*(8/√35) ≈ 2.68

The confidence interval is given by:

Lower Limit = $\bar{x}$ - Margin of Error

Upper Limit = $\bar{x}$ + Margin of Error

Substituting the values, we get:

Lower Limit = 36 - 2.68 ≈ 33.32

Upper Limit = 36 + 2.68 ≈ 38.68

Therefore, the 95% confidence interval for the mean time that all half-hour local TV news broadcasts devote to U.S. foreign policy is (33.32, 38.68).

To find the 95% confidence interval for the mean number of pounds of trash per person per week, we can use the following formula:

CI = X + Zα/2 * (σ/√n)

σ = population standard deviation = 7.8 pounds

Plugging in the values, we get:

CI = 31.5 ± 1.96 \times(7.8/√120)

CI = 31.5 ± 1.96 \times 0.711

CI = 31.5 ± 1.39

Therefore, the 95% confidence interval for the mean number of pounds of trash per person per week is (30.11, 32.89).
