The distance from any point on the circle to the origin

Answer: The answer is (a). the distance from any point in the circle to the origin.

Step-by-step explanation: We know that to find the standard equation of a circle centred at the origin, we always use the distance formula. We are to select the correct measurement for the radius from the options given.

In a circle, as shown in the attached figure, the radius 'r' is the distance from any point 'P' on the circle to the centre 'O' of the circle. The centre of the circle in standard form is usually the origin.

So, we can say that radius measures the distance from any point on the circle to the origin.

Thus, (a) is the correct option.

Answer:

- 508

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus

$a_{81}$ = - 28 + (- 6 × 80) = - 28 - 480 = - 508

Which products result in a perfect square trinomial? select three options. (negative x 9)(negative x minus 9) (x y x)(x y x) (2

erastovalidia [21]

The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)

<h3>What is an polynomial?</h3>

A polynomial is an expression that involves only the operations of a<em>ddition, subtraction, multiplication</em> of variables.

A perfect square trinomial is the square of a binomial

(x + y + x)(x + y + x) = (2x + y)²

(2x - 3)(-3 + 2x) = (2x - 3)²

(4y² + 25)(25 + 4y²) = (4y² + 25)²

The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)

The revenue for a small business is modeled by the function R(x) = 5x where represents the number of items soldThe cost function

MAVERICK [17]

Answer:

$P(x) = 3x - 10$

Step-by-step explanation:

Given

$R(x) = 5x$

$C(x) = 10 + 2x$

Required

Determine $P(x) = (R - C)(x)$

In functions;

$(f - g)(x) = f(x) - g(x)$

So, we have:

$P(x) = (R - C)(x)$

$P(x) = R(x) - C(x)$

Substitute values for R(x) and C(x)

$P(x) = 5x - (10 + 2x)$

Open bracket

$P(x) = 5x - 10 - 2x$

Collect Like Terms

$P(x) = 5x - 2x- 10$

$P(x) = 3x - 10$

Factory produces 1000 bottles of Hosta sauce in a day. 50 bottles are selected at random to determine whether they were the corr

BabaBlast [244]

<span>Based on this sample, and assuming the word "widget" means removed, the answer is four. They only tested 50 bottles and found four (one under, three over). The question also contains the word "Jack's, " the meaning is unclear. The factory shipped 1000 bottles of Hosta sauce, assuming the same ratio as the random sample (0.0008%) then the factory shipped 80 bottles that are incorrect.</span>
