The zero's of the polynomial 4x² - 4x - 8 are as follows:

x = 2 or x = -1

Zeros of a polynomial can be defined as the points where the polynomial becomes zero as a whole. In other words, the zeros of a polynomial p(x) are all the x-values that make the polynomial equal to zero.

Therefore, let's find the zero's of the polynomial.

4x² - 4x - 8 = 0

divide through by 4

x² - x - 2 = 0

x² + x - 2x - 2 = 0

x(x + 1) -2(x + 1) = 0

(x - 2)(x + 1) = 0

Therefore,

The second term in the sequence is 0.

To solve the problem, we can use the fact that each term after the second is the sum of the two preceding terms. Let's call the first term a and the second term b. Then, according to the problem, we have:

a = 3 (the first term is 3)

b = ?

c = a + b = 3 + b

d = b + c = b + (3 + b) = 2b + 3

e = c + d = (3 + b) + (2b + 3) = 3b + 6

We also know that the fifth term is 3, so we can set e equal to 3 and solve for b:

3b + 6 = 3

3b = -3

b = -1

Therefore, the second term in the sequence is 0, since each term after the second is the sum of the two preceding terms and the first term is 3.

There are 6,227,020,800 ways in which Aaron can arrange the 13 songs on the playlist.

To determine the number of ways Aaron can arrange the 13 songs on the playlist, we can use the concept of permutations. Since the order of the songs matters (i.e., each arrangement is different), we can use the formula for permutations.

The number of ways to arrange n items in a specific order is given by n factorial, denoted as n!. The factorial of a number n is the product of all positive integers less than or equal to n.

In this case, Aaron has 13 songs to arrange on the playlist, so the number of arrangements can be calculated as:

13! = 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

The pollster should survey approximately 2,401 U.S. voters to estimate the true proportion of voters who oppose capital punishment with 95% confidence and a margin of error of 2%.

In order to estimate the true proportion of U.S. voters who oppose capital punishment with a 95% confidence level and a margin of error of 2%, the pollster should survey approximately 2,401 voters.



To calculate the sample size needed for this estimation, we can use the formula:

n = (Z² * p * q) / E²

where n is the sample size, Z is the z-score corresponding to the confidence level (in this case, 1.96 for 95% confidence), p is the estimated proportion of voters who oppose capital punishment, q is the estimated proportion of voters who support capital punishment (which is 1-p), and E is the desired margin of error (in this case, 0.02).

Assuming a conservative estimate of p = q = 0.5, we can plug in the values and solve for n:

n = (1.96² * 0.5 * 0.5) / 0.02² ≈ 2,401

Therefore, the pollster should survey approximately 2,401 U.S. voters to estimate the true proportion of voters who oppose capital punishment with 95% confidence and a margin of error of 2%.



In conclusion, to estimate the true proportion of U.S. voters who oppose capital punishment with a 95% confidence level and a margin of error of 2%, the pollster should survey approximately 2,401 voters.

The area of the part of the plane 2x + 5y + z = 10 that lies in the first octant is 8√6/5 square units.

The first octant is the region of space where x, y and z are all positive. We need to find the area of the surface of the part of the plane 2x + 5y + z = 10 that lies in the first octant.

To find the surface area, we need to first parameterize the surface. We can do this by fixing one variable and expressing the other two in terms of it. Let's fix x:

2x + 5y + z = 10

Solving for z, we get:

z = 10 - 2x - 5y

Now, we can express y in terms of a parameter t:

y = t

And we can express z in terms of x and t:

z = 10 - 2x - 5t

So the parameterization of the surface is:

r(x, t) = (x, t, 10 - 2x - 5t)

To find the surface area, we need to compute the magnitude of the cross product of the partial derivatives of r with respect to x and t:

|∂r/∂x x ∂r/∂t| = |<1, 0, -2>| x |<0, 1, -5>| = |<2, 1, 1>|

= √(2^2 + 1^2 + 1^2) = √6

So the surface area is:

∫∫ √6 dA

where the double integral is over the region in the first octant where 2x + 5y + z = 10. We can express this region as:

0 ≤ x ≤ 5

0 ≤ y ≤ (10 - 2x)/5

0 ≤ z ≤ 10 - 2x - 5y

So the integral becomes:

∫₀^₅ ∫₀^(10-2x)/5 √6 dz dy dx

Evaluating this integral, we get:

∫₀^₅ ∫₀^(10-2x)/5 √6 dz dy dx = √6 ∫₀^₅ ∫₀^(10-2x)/5 dz dy dx

= √6 ∫₀^₅ (10-2x)/5 dy dx

= √6 ∫₀^₅ 2 - (2/5)x dx

= √6 [2x - (1/5)x²] from 0 to 5

= √6 [10 - (1/5)(25)]

= √6 (8/5)

According to the Census 2000, the overall American Indian and Alaska Native population had a younger median age compared to the national median age. The national median age in 2000 was 35.3 years, whereas the median age for the American Indian and Alaska Native population was 26.3 years.

This can be attributed to several factors, including higher fertility rates and lower life expectancies in some American Indian and Alaska Native communities. Additionally, many Native American tribes have a strong cultural emphasis on family and community, which can contribute to larger family sizes and a younger overall population. It is important to note that these demographic trends may have shifted in the years since the Census 2000, and that there is significant diversity within the American Indian and Alaska Native population in terms of age, geography, and culture.

Answer:

he correct answer is c. vD = -7 vs = 5.

The Doppler shift equation is:

f = f' (v - vD) / (v - vS)

Where:

f is the frequency detected

f' is the frequency emitted

v is the speed of sound

vD is the velocity of the detector

vs is the velocity of the source

In this case, the source is traveling at 5 m/s away from the detector, the detector is traveling at 7 m/s toward the source, and there is a 3 m/s wind blowing from the source toward the detector.

The velocity of the detector is negative because it is moving towards the source. The velocity of the source is positive because it is moving away from the detector.

Step-by-step explanation:

Answer:

70%

Step-by-step explanation:

If 3 of the pins were knocked down, that means 7 pins were still standing.

Next, to find what percent 7 is of 10, divide 10 by 100 to get 0.1.

0.1 is 1% of 10, so we need to divide 7 by 0.1 to find the percentage, which is 70.

No, the variances are not similar enough to use the pooled t test. The ratio of the two variances (25/8) is greater than 3, which is the typical cutoff for determining similarity of variances. Therefore, an alternative method such as the Welch's t-test or a non-parametric test should be used to compare the means.

To determine if the variances are similar enough to use a pooled t-test, you can perform an F-test for equality of variances. Follow these steps:

1. Calculate the F statistic by dividing the larger variance by the smaller variance: F = var2 / var1 = 25 / 8 = 3.125.

2. Determine the degrees of freedom for each group: df1 = 10 - 1 = 9 and df2 = 10 - 1 = 9.

3. Check the F critical value for the given degrees of freedom and chosen significance level (e.g., 0.05) using an F-distribution table or a calculator. For df1 = 9 and df2 = 9 at a 0.05 significance level, the F critical value is approximately 3.18.

4. Compare the calculated F statistic to the F critical value: 3.125 < 3.18.

Since the F statistic is less than the F critical value, we fail to reject the null hypothesis that the variances are equal. Therefore, the variances are similar enough to use the pooled t-test to evaluate differences in the means. The answer is yes.

By finding the inverses we can see that:

Two functions g(x) and g⁻¹(x) are inverses if:

g⁻¹(g(x)) = x

Here we know that the function g is defined by:

g={(-8, -3), (-3, 2), (3, 0), (5, 6)}

And we want to find:

g⁻¹(-3)

On the table we can see that g(-8) = -3, then:

g⁻¹(-3) = -8

And we have:

h(x) = -2x + 13

Evaluating on the inverse we should get:

h(h⁻¹(x)) = x

            = -2*h⁻¹(x)   + 13 = x

Solving for the inverse:

h⁻¹(x) = (x - 13)/-2

Now we can get the product:

The dimensions of the deck are 26 meters by 16 meters and 84 meters of fencing will need to be purchased for the deck and pool area.

Let's denote the width of the deck as 'x'.

The length of the pool is 20 meters, and the width is 10 meters.

The combined area of the pool and the deck is 264 square meters.

The area of the pool is length times width: 20 × 10 = 200 square meters.

The area of the deck is (20 + 2x)(10 + 2x) - 200 square meters. We subtract 200 square meters to account for the area of the pool.

Therefore, the polynomial equation representing the given information is:

(20 + 2x)(10 + 2x) - 200 = 264

(200 + 40x + 20x + 4x^2) - 200 = 264

4x²+ 60x = 264

4x² + 60x - 264 = 0

Factoring out a common factor of 4:

4(x² + 15x - 66) = 0

Factoring the quadratic equation:

(x + 18)(x - 3) = 0

The width of the deck is x = 3 meters.

The dimensions of the deck can be found by adding twice the width to the length and width of the pool:

Length of the deck = 20 + 2x = 20 + 2(3) = 26 meters

Width of the deck = 10 + 2x = 10 + 2(3) = 16 meters

Therefore, the dimensions of the deck are 26 meters by 16 meters.

To calculate the length of fencing required, we need to consider the perimeter of the deck.

Perimeter of the deck = 2×(Length of the deck + Width of the deck)

Perimeter of the deck = 2 × (26 + 16)

Perimeter of the deck = 2 × 42
