Answer:

C. 84.8 m

Step-by-step explanation:

Circumference of circle = D x 3.14

D = 27 m

Let's solve

27 x 3.14 = 84.78 m

So, the circumference of the circle is C. 84.8 m

Answer:

Option C) 84.8 is the correct answer.

Step-by-step explanation:

Here we have given that the diameter of circle is 27 m and we have to find the circumference of circle. The formula to find circumference of circle is :

[tex]\dashrightarrow\sf{C = \pi d}[/tex]

Where :

Thus, finding the circumference of circle by substituting the given values in the formula :

[tex]\dashrightarrow\sf{C = \pi d}[/tex]

[tex]\dashrightarrow\sf{C = \pi \times d}[/tex]

[tex]\dashrightarrow\sf{C = 3.14 \times 27}[/tex]

[tex]\dashrightarrow\sf{C = 84.78 \: m}[/tex]

[tex]\dashrightarrow\sf{C \approx 84.8\: m}[/tex]

Hence, the circumference of circle is 84.8 m.

The inequality that represents all possible values for the amount of money that Joann has is 21 ≤ J ≤ 50.

Let's call the amount of money that Joann has in her wallet "J" and the amount of money that Shana has in her wallet "S".

We know that the total amount of money they have is at least $56 and at most $85. Therefore, we can write two inequalities:

J + S ≥ 56 (the total is at least $56)

J + S ≤ 85 (the total is at most $85)

We also know that Shana has only $35 in her wallet. We can substitute this value for S in the inequalities to get an inequality that represents all possible values for the amount of money that Joann has:

J + $35 ≥ 56 (substituting S = $35 in the first inequality)

J + $35 ≤ 85 (substituting S = $35 in the second inequality)

Simplifying these inequalities by subtracting $35 from both sides, we get:

J ≥ 21 (the amount of money Joann has is at least $21)

J ≤ 50 (the amount of money Joann has is at most $50).

Answer:

  (a) ±{1, 2, 5, 10}

  (b) attached

  (c) {-2, -1, 5}

  (d) P(x) = (x +2)(x +1)(x -5)

Step-by-step explanation:

You want the possible and actual rational zeros for P(x) = x^3-2x^2-13x-10, and the factored form of the polynomial.

The rational root theorem tells you the possible rational zeros of a polynomial will be of the form ...

  ±(divisor of the constant)/(divisor of the leading coefficient)

The leading coefficient is 1, and the divisors of the constant are {1, 2, 5, 10}, so the possible rational zeros are ...

  {±1, ±2, ±5, ±10}

The attached graph shows the actual zeros of P(x) to be {-2, -1, 5}.

Each zero q corresponds to a factor (x -q). The factored form of the polynomial is ...

  P(x) = (x +2)(x +1)(x -5)

To the right of 1.61, 9.24, and 15.09, the area under the X² curve with five degrees of freedom is 0.078, 0.0001, and 0, respectively.

A surface's area can be measured in two dimensions by multiplying its length by its breadth. It is employed to determine the size of a room or a plot of land. The size of a shape, like a circle or a square, can also be determined using area. Area is frequently expressed in square metres or square feet.

Here in the question,

(a)1.61

The following formula can be used to determine the area under the 1.61-degree curve with five degrees of freedom to the right:

Area = 1 - Φ(x; df)

Where df stands for the degrees of freedom and (x; df) is the cumulative distribution function of the chi-square distribution.

For df = 5, Φ(1.61; 5) = 0.922.

As a result, 1 - 0.922 = 0.078 represents the area under the 1.61-degree curve with 5 degrees of freedom to the right.

(b) 9.24

For df = 5, Φ(9.24; 5) = 0.9999.

As a result, 1 - 0.9999 = 0.0001 is the value of the area under the X² curve with 5 degrees of freedom to the right of 9.24.

(c) 15.09

For df = 5, Φ(15.09; 5) = 1.

As a result, 1 - 1 = 0 represents the area under the 15.09-based X² curve with 5 degrees of freedom to the right.

The area under the X² curve with five degrees of freedom to the right of 1.61, 9.24, and 15.09, respectively, is 0.078, 0.0001, and 0.

1. The solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s] : t, s ∈ R}

2. The solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s - 3] : t, s ∈ R}

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13. 2x - 5 and 13 are expressions in this case. These two expressions are joined together by the sign "=".

To find the solution set in parametric vector form for the equation x₁ + 3x₂ - 2x₃ = 0, we can write:

x₁ = t      (arbitrarily setting x1 = t)

x₂ = s

x₃ = (3/2)t + (3/2)s

where t and s are arbitrary parameters.

Therefore, the solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s] : t, s ∈ R}

This is a set of infinitely many vectors that lie on a plane in three-dimensional space.

Part 2

For the equation x₁ + 3x₂ - 2x₃ = -6, we can rewrite it as x₁ + 3x₂ - 2x₃ = 0 - 6, which is of the same form as the equation in Part 1, but with a constant on the right-hand side.

Using the same method as in Part 1, we can find the solution set as:

x₁ = t

x₂ = s

x₃ = (3/2)t + (3/2)s - 3

where t and s are arbitrary parameters.

Therefore, the solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s - 3] : t, s ∈ R}

This is also a set of infinitely many vectors that lie on a different plane in three-dimensional space.

Comparing the two solution sets, we can see that they are both sets of infinitely many vectors and have a similar form (parametric vector form). However, they lie on different planes in three-dimensional space, and the second set is shifted downward by 3 units along the third axis.

according to the question, the PLUS Loan will have a higher balance due at the time of repayment by $233.80 ($11,966.11 - $11,732.31).

Divide the principal times the interest rates, the length of time, and various other factors to arrive at simple interest. Simple return = principle + interest + hours is the marketing formula. The easiest way to compute interest is with this method. The most typical technique to figure out interest is to use a portion of the principal sum. He is only going to pay his share of the 100% interest, for example, if he loans $100 form a friend then agrees to pay it off with 5% interest. $100 (0.05) corresponds to $5. Interest must be paid as you borrow money and must be added to any loans you make. Interest is often determined as a yearly proportion of the loan total. The interest on the loan is this percentage.

given,

To compare the two loans, we need to calculate the total balance due for each loan at the time of repayment. We can start by calculating the balance due for the Unsubsidized Stafford Loan:

Principal: $10,720

Interest rate: 5.95% per year, compounded monthly

Time: 6 months grace period + 6 months repayment = 1 year

Number of periods: 12 months x 1/12 month per period = 12 periods

Using the formula for compound interest, the balance due on the Unsubsidized Stafford Loan after 1 year is:

B = P(1 + r/n)^(nt) + I [(1 + r/n)^(nt) - 1]/(r/n)

where B is the balance due, P is the principal, r is the annual interest rate, n is the number of times per year the interest is compounded, t is the time in years, and I is the monthly payment.

Plugging in the numbers, we get:

B = $10,720(1 + 0.0595/12)^(121) + $0 [(1 + 0.0595/12)^(121) - 1]/(0.0595/12)

B = $11,732.31

Now, let's calculate the balance due for the PLUS Loan:

Principal: $11,443.63

Interest rate: 6.55% per year, compounded monthly

Time: 6 months repayment

Number of periods: 6 periods

Using the same formula for compound interest, the balance due on the PLUS Loan after 6 months is:

B = $11,443.63(1 + 0.0655/12)^(120.5) + $0 [(1 + 0.0655/12)^(120.5) - 1]/(0.0655/12)

B = $11,966.11

Therefore, the PLUS Loan will have a higher balance due at the time of repayment by $233.80 ($11,966.11 - $11,732.31). Thus, the Unsubsidized Stafford Loan will have a lower balance due at the time of repayment compared to the PLUS Loan.
