The problem is saying there are two distinct zeros, and both are strictly lie between 0 and 1. The least positive integer value of "a" is 5 for which such a polynomial exists.

Let f(x) = ax² - bx + c , be our polynomial.

where a,b are integers coefficient and c constant. It has two distinct real roots lying between 0 and 1. f(x) can be written as, f(x) = a(x−α)(x−β)

where α and β are the roots of the equation.

we can be observed that f(0)f(1) > 0

As a,b and c are integers f(0)f(1) > 1

f(0) = aαβ , f(1)=a(1−α)(1−β)

=> a²(α)(1−α)(β)(1−β) > 0 -------(1)

Using A.M ≥ G.M, we get

(α+1−α+β+1−β)/4 > (αβ(1−α)(1−β))¹/⁴

Arithmetic Mean and Geometric Mean cannot be equal because the equation has distinct roots.

a²/16 > a²(αβ(1−α)(1−β)).

=> a²/16 > 1

=> a > 4

Therefore, the minimum value of 'a' is 5

The discriminant of the equation,

Δ = b²−4ac ≥ 0

=> b² >20c

consider the minimum value of c = 1,

we get b² >20

=> Minimum Value of b = 5.

Hence, the least positive integer of 'a' is 5.

Answer:

i think it will be 70 yd

Step-by-step explanation:

(14×5)yd= 70 yd

Answer:

The total area is 179.25yd²

Step-by-step explanation:

You need to break this down into two parts: the rectangle on the left side, and the semicircle on the end.

The radius of the circle is five yards, giving it a diameter of 10 yards.  That diameter is also the height of the rectangle, meaning that the rectangle has an area of 14yd × 10yd = 140yd²

The area of a circle is equal to pi times the square of its radius.  Given that we only have a semicircle, we need to take that and divide it by two:

a = πr² ÷ 2

a = π × 5² ÷ 2

a = 3.14 × 25 ÷ 2

a = 3.14 × 12.5

a = 39.25

So the circle has an area of 39.25 square yards.

We can then can then add the areas together, giving us a total of 179.25 square yards.

a) A system of equations that could be used to determine the number of gifts Jackson wrapped and the number of gift bags he prepared is:

b) The variables used to write the system of equations are the number of single gifts, x, and the number of gift bags, y.

A system of equations is two or more equations solved simultaneously.

They are also known as simultaneous equations because the solutions of the variables are obtained at the time.

The time for wrapping a single gift = 6 minutes

The time for wrapping a gift bag = 2 minutes

The total number of gifts prepared = 25

The total time used in preparing the 25 gifts = 110 minutes

Let the number of single gifts = x

Let the number of gift bags = y

6x + 2y = 110 ... Equation 1

x + y = 25 ... Equation 2

Multiply Equation 2 by 2:

2x + 2y = 50 ... Equation 3

Subtract Equation 3 from Equation 1:

6x + 2y = 110

-

2x + 2y = 50

4x = 60

x = 15

From Equation 2:

We are asked to calculate the magnitude of the discontinuity in the curvature of the quadratic spline function Q(x) at a specific point x = xj.

To calculate the magnitude of the discontinuity in the curvature of Q(x) at x = xj, we first need to find the expression for the curvature of the quadratic spline. The curvature is given by the second derivative of Q(x) with respect to x. By taking the second derivative of Qj(x) = αj(x - xj)² + βj(x - xj) + γj, we can obtain the expression for the curvature.

Once we have the expression for the curvature, we evaluate it at x = xj to find the value of the curvature at the junction point. The magnitude of the discontinuity in curvature is the absolute difference between the curvature values of the adjacent splines at x = xj.

To simplify the answer, we can substitute the given values of αj, βj, and γj into the expression for the curvature and perform any necessary algebraic simplifications. The final result will be the magnitude of the discontinuity in the curvature at x = xj.

W+ is closed under scalar multiplication. Since W+ is closed under addition and scalar multiplication, it is a subspace of V. This completes the proof.

(a) Proof that \(W∩W^⊥ = {0}\):
Proof:
Let's suppose for contradiction that there is a non-zero vector, say v, in the intersection of W and its orthogonal complement W+.
Since v is in W+, then it is orthogonal to all the vectors in W. Since v is also in W, then v is orthogonal to itself. Therefore, (v, v) = 0.
Since (v, v) = 0 and v is non-zero, it follows that v is not positive-definite. This is a contradiction since we are working in an inner product space and all vectors are positive-definite. Therefore, the intersection of W and W+ must be {0}. This completes the proof.
(b) Proof that \(W^⊥\) is a subspace of V:
Proof:

Let x and y be vectors in W+. Then (x+y, w) = (x, w) + (y, w)

= 0, since both x and y are in W+.
Therefore, W+ is closed under addition.
Let a be a scalar and x be a vector in W+. Then (ax, w)

= a(x, w)

= 0, since x is in W+.
Therefore, W+ is closed under scalar multiplication.
Since W+ is closed under addition and scalar multiplication, it is a subspace of V. This completes the proof.

Step-by-step explanation:

Answer:

-5.2

Step-by-step explanation:

Therefore, the sample standard deviation of the given numbers 4, 9, 5, 8, 7 is approximately 2.07.

To find the sample standard deviation of a set of numbers, we can use the following steps:

Calculate the mean (average) of the numbers: (4 + 9 + 5 + 8 + 7) / 5 = 33 / 5 = 6.6

Subtract the mean from each number and square the result:

(4 - 6.6)^2 = (-2.6)^2 = 6.76

(9 - 6.6)^2 = (2.4)^2 = 5.76

(5 - 6.6)^2 = (-1.6)^2 = 2.56

(8 - 6.6)^2 = (1.4)^2 = 1.96

(7 - 6.6)^2 = (0.4)^2 = 0.16

Calculate the sum of the squared differences: 6.76 + 5.76 + 2.56 + 1.96 + 0.16 = 17.2

Divide the sum of squared differences by (n - 1), where n is the number of data points: 17.2 / (5 - 1) = 4.3

Take the square root of the result to get the sample standard deviation: √4.3 ≈ 2.07

The formula for the nth term of the given sequence is: a_n = (4n + 1) / (n!)

Numerators:

-The numerators of the sequence follow the pattern of 4n + 1, where n is the position of the term in the sequence. We can observe that each numerator is obtained by adding 4 to the product of n and 1.

Denominators:

-The denominators of the sequence correspond to the factorials of the corresponding n value. The denominator for each term is given by n!, where n is the position of the term.

Combining the above observations, we can express the nth term of the sequence as:

a_n = (4n + 1) / (n!)

For example:

- The numerator of the first term is 5, which is obtained by adding 4 to the product of 1 and 1, i.e., 4(1) + 1. Similarly, the numerator of the second term is 9, which is obtained by adding 4 to the product of 2 and 1, i.e., 4(2) + 1.

- The denominator of each term is the factorial of the corresponding n value, i.e., n! For example, the denominator of the third term is 6!, which is equal to 720.
- Therefore, the nth term of the sequence can be expressed as (4n + 1) / (n!).

For example, to find the 4th term of the sequence, we plug in n=4 into the formula:

a_4 = (4(4) + 1) / (4!) = 17/24

Similarly, to find the 6th term of the sequence, we plug in n=6 into the formula:

The final selling price of a $320 item with a 20% discount is $256. A product or service is sold at a discounted price for a limited time or during a specific promotional period.

We can multiply the original price by the % decrease as a decimal (i.e., as a fraction out of 1) and then subtract the result from the original price to determine the sale price of an item that has been marked down by a specific percentage.

In this instance, the item has been reduced by 20%, or 0.20 as a decimal. As a result, we may determine the discount amount as:

Discount: $64 ($0.20 x $320)

We must deduct the discount from the original price to determine the sale price:

Discount price: $320 less $64 equals $256.

Hence, the final selling price of a $320 item with a 20% discount is $256.
