The required measurement of each interior angle of the animal pen

An  interior angle is a point inside a shape. The polygons are the shut shape that has sides and vertices. A standard polygon has generally its interior angle equivalent to one another. For instance, a square has generally its  interior angle equivalent to the right point or 90 degrees.

The question expects us to track down the inside point of a customary heptagon.

To do this initially compute the outside angle of that polygon.

The amount of outside angle is 360°. A heptagon has 7 sides.

Along these lines, one exterior angle = 360°/7 = 51.4°

inside angle+exterior angle=180°

Interior angle = 180-51.4 = 128.6°

Thus, required interior angle is 128.6°.

The polynomial function is P(x) = x⁴ - 14x³ + 59x² - 50x - 74

A polynomial is a function in which the least power of the unknown is 2.

The root of a polynomial is the value of the unknown which makes the polynomial equal zero.

Since we have that the given polynomial has roots 1 - √3 and 6 - i.

We also know that their conjugates 1 + √3 and 6 + i are also roots of the polynomial.

So, the factors of the polynomial are

So, the required polynomial is P(x) = [(x - 1) + √3][(x - 1) - √3][(x - 6) + i][(x - 6) - i]

= [(x - 1)² - (√3)²][(x - 6)² - i²]    (Since a² - b² = (a - b)(a + b))

= [(x - 1)² - 3][(x - 6)² - (- 1)]

= [(x - 1)² - 3][(x - 6)² + 1]

Expanding the brackets, we have

= [x² - 2x + 1 - 3][(x² - 12x + 36 + 1]

= [x² - 2x - 2][(x² - 12x + 37]

= x⁴ - 12x³ + 37x² - 2x³ + 24x² - 74x - 2x² + 24x - 74

Collecting like terms, we have

= x⁴ - 14x³ + 59x² - 50x - 74

So, the polynomial is P(x) = x⁴ - 14x³ + 59x² - 50x - 74

Answer:

A and B

Step-by-step explanation:

The triangle is labeled that all three sides are equal and all three angles are equal; thus, it is an equilateral triangle and “B” is correct.

Acute triangles have all acute angles. Understanding that the triangle is equilateral, equilateral triangles have all equal angles, and the total of all three angles in a triangle is 180, we can determine that all three angles are acute and the triangle is acute, so “A” is right. (one angle = x; three angles are equal and add up to 180 —> 3x = 180; x = 60; all angles are acute).

The marked price is $1518 and the rate of the discount is 8.9%.

The marked price or list price is the amount that appears on a product's label. This is the price that the product will be sold for. But this price might be discounted in some way, and the product's real selling price might be less than the advertised price. Typically, MP is used to indicate it.

This was the initial selling price, but $194 was deducted, making the final price $1394.

Use the following formula to determine percent markdown:

(Markdown amount/Selling price)×100 is the percent markdown.

To locate Markdown

Original Selling Price – Markdown Price

Connect what you have now.

Markdown=$1518-$1394

The area of the triangle will increase at a rate of 3.81 m² per second

Given,

The length of the sides of the triangle are base, 12 m and hypotenuse 15 m

Area of the triangle = 1/2 bh

We have to find h;

That is,

Sin ∅ = opposite side /hypotenuse = h/15

h = 15Sin ∅

d∅/dt = 0.06rad/s

Now,

A = bh/2 = 12 × 15sin∅/2

A = 90sin∅,

By differentiating this equation with respect to A, we have

d(A)/dt = 90cos∅d∅/dt

d(A)/dt = 90cos∅(0.06)

∅ = π/4, cosπ/4 = 0.7071

The coordinates of the point dividing the join of given points will be equal to (1, 3).

If we need to find the coordinates of a point P(x, y) dividing the join of points (x₁, y₁) and (x₂, y₂) in the ratio m:n then the formula is expressed as

P(x, y) = [(mx₂ + nx₁/m + n), (my₂ + ny₁/m + n)]

We have the values as m:n = 2:3 and

(x₁, y₁) = (-1, 7) and (x₂, y₂) = (4, -3)

Answer:

A linear function can be represented by a graph that is a straight line. The equation for a linear function is of the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis). The slope of the line tells us how steep the line is, and whether it has a positive or negative slope. A positive slope means that the line is sloping upwards from left to right, while a negative slope means that the line is sloping downwards from left to right.

The balance of Marissa’s retirement account after 15 years if She makes an initial deposit of $1,000. Her contributions are $500 a month for the next 15 years is $8500.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given data:

Initial deposit = $1000

Her contributions are $500 a month for the next 15 years

Amount after 15 years = Initial deposit  + 15 × 500

Answer:

The answer to the problem is:

(i) The speed of the car at B is -4 ms$^{-1}$.

(ii) The distance AB is 32 meters.

(iii) The time taken for the car to travel from B to C is 10 seconds.

Step-by-step explanation:

To find the speed of the car at B, we can use the formula $v = v_0 + at$, where $v$ is the final speed, $v_0$ is the initial speed, $a$ is the acceleration, and $t$ is the time. In this case, $v_0 = 20$ ms$^{-1}$, $a = -6$ ms$^{-2}$, and $t = 4$ s. Plugging these values into the formula gives us:

$v = 20 + (-6)(4) = 20 - 24 = -4$ ms$^{-1}$

Thus, the speed of the car at B is -4 ms$^{-1}$.

To find the distance AB, we can use the formula $d = v_0t + \frac{1}{2}at^2$, where $d$ is the distance, $v_0$ is the initial speed, $a$ is the acceleration, and $t$ is the time. In this case, $v_0 = 20$ ms$^{-1}$, $a = -6$ ms$^{-2}$, and $t = 4$ s. Plugging these values into the formula gives us:

$d = (20)(4) + \frac{1}{2}(-6)(4^2) = 80 - 48 = 32$ meters

Thus, the distance AB is 32 meters.

To find the time taken for the car to travel from B to C, we can use the formula $v^2 = v_0^2 + 2ad$, where $v$ is the final speed, $v_0$ is the initial speed, $a$ is the acceleration, and $d$ is the distance. In this case, $v_0 = -4$ ms$^{-1}$, $v = 20$ ms$^{-1}$, $a = 2$ ms$^{-2}$, and $d$ is the distance from B to C. We can find this distance by using the formula for distance and setting $t = 0$, since we're looking for the time it takes the car to travel from B to C, not from A to B:

$d = (20)(0) + \frac{1}{2}(-6)(0^2) = 0 - 0 = 0$ meters

Thus, the distance from B to C is 0 meters. Plugging these values into the formula gives us:

$20^2 = (-4)^2 + 2(2)(0) = 16 + 0 = 16$

We can solve this equation for $t$ to find the time it takes the car to travel from B to C:

$t = \sqrt{\frac{v^2 - v_0^2}{2a}} = \sqrt{\frac{20^2 - (-4)^2}{2(2)}} = \sqrt{\frac{400}{4}} = \sqrt{100} = 10$ seconds

Thus, the time taken for the car to travel from B to C is 10 seconds.

The velocity-time graph for the journey from A to C would have a positive slope from A to B, a negative slope from B to C, and a positive slope from C to the end of the journey.

The quotient of given polynomials division is x+2. So, the correct answer is option A.

A quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Given that, (x²+3x+2)÷(x+ 1)

x²+3x+2 can be written as

x²+1x+2x+2 (Splitting of middle term)

When two values are directly proportional, it indicates that if one increases by a specific percentage, the other also increases by the same percentage, direct proportionality is represented by a straight line and it equation is of the form -

y = kx

k = y/x

where [k] is the constant

Given is that the number of questions [y] completed and time [x] it takes to complete them are proportional to each other.

The number of questions [y] completed is proportional to the time [x] it takes to complete them.

That means,

y ∝ x

y = kx, where k is constant.

k = y/x

So, we can write;

y₁/x₁ = y₂/x₂

According to the question:

Let  y₁= 6, x₁= 15, y₂= 11.

Substituting the values,

6/15 = 11/x₂

x₂ = 11 x 15 / 6

x₂ = 11 x 5 / 2

x₂ = 55 /2

According to the Law of Demand, there is an indirect correlation between a good or service's price and the amount of that good or service that customers are willing and able to purchase .In other words, if an item's price increases, people are less able and willing to buy it, and vice versa.

According to the law of demand, the demand curve demonstrates the inverse relationship between the amount of items sought and price.

The amount of a good that is demanded will decrease as its price rises. The demand curve will therefore have a negative slope if the law of demand and its underlying assumptions are true.
