What is the change due if a $50 bill is tendered for a charge of $9.76?

The value of n and the distance from Point B to Point C cannot be determined without specific coordinates for these points. Given that B is the midpoint between points A and C, the x-coordinate for Point B should be n/2. The distance between the points would be calculated using the distance formula derived from the Pythagorean Theorem.

To calculate the distance between points in a graph, we typically use the distance formula, which is derived from the Pythagorean Theorem. From our given information, Point A lies on the y-axis and has the same y-coordinate as Point B. Point C is graphed at (n, -3). Given that the distance is the same from Point B to both points A and C, this implies that Point B is the midpoint between Points A and C. The coordinates of the midpoint are obtained by averaging the x and y coordinates of the two points. Therefore, the x-coordinate of Point B must be n/2.

The distance from Point B to Point C (or similarly to Point A) can be obtained using the distance formula: sqrt((x2−x1)² + (y2−y1)²), where x1, y1 are the coordinates of one point and x2, y2 are the coordinates of the other point.

However, without concrete values for some of these points in the given equation, we cannot provide a specific numerical value for the distance or n. This calculation depends specifically on the placement of the points on the graph.

Answer:

Dist = 45 m/h * x h

Step-by-step explanation:

We know a speed is a measure of distance over time:  speed = dist / time

In this case, we are looking for a distance expressed in terms of time.

So, we only need to modify the formula a bit: dist = speed * time

We don't know the time (which will be a variable), but we know their speed.  So, the formula becomes:

Dist = 45 m/h * x h

Enter the number of hours in the formula and that will give you an approximation of the distance traveled within that time (approximation since our result will be rely on an average).

1. Only constraint 2 would be met if 18 pairs of leather boots and 36 pairs of running  shoes were ordered.

2. Only constraint 1 would be met if 12 pairs of leather boots and 36 pairs of running shoes were ordered.

[tex](19.25\ t)(\frac{2,000\ lbs}{1\ t})=38,500\ lbs[/tex]

Therefore, you get this result:

[tex]19.25\ t=38,500\ lbs[/tex]

Answer:

See below in bold.

Step-by-step explanation:

The 40 is the adjacent side of the triangle that can be drawn and the 9 is the opposite side.

The hypotenuse =  sqrt (40^2 + 9^2) = 41.

sine = opp/hyp = 9/41 = 0.2195.

cosine = 40/41 = 0.9756.

tangent = 9/40 =0.2250.

cosec = 1/ sine =  41/9 = 4.5556.

secant = 1  / cosine = 41/40 = 1.0250.

cotangent = 1 / tangent =  40/9 = 4.4444.

The decimal forms are  correct to the nearest ten thousandth.

The values of the six trigonometric functions are:

sin θ = 9/41, cos θ = 40/41, tan θ = 9/40, cot θ = 40/9, sec θ = 41/40, cosec θ = 41/9.

The values of all trigonometric functions dependent on the value of the ratio of sides of a right-angled triangle are known as trigonometric ratios. The trigonometric ratios of a right-angled triangle's sides with regard to any of its acute angles are known as that angle's trigonometric ratios.

The three sides of the right-angled triangle are:

Hypotenuse (the longest side)

Perpendicular (opposite side to the angle)

Base (Adjacent side to the angle)

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

The trigonometry ratios for a specific angle ‘θ’ is given below:

Trigonometric Ratios:

Sin θ =  Perpendicular/Hypotenuse

Cos θ = Base/Hypotenuse

Tan θ = Perpendicular/Base or Sin θ/Cos θ

Cot θ = Base/Perpendicular or 1/tan θ

Sec θ = Hypotenuse/Base or 1/cos θ

Cosec θ = Hypotenuse/Perpendicular or 1/sin θ

According to the Pythagoras theorem, we can say that in a right-angled triangle:

Hypotenuese² = Base² + Perpendicular²

We have to find the six trigonometric functions of an angle in standard position if the point with coordinates (40, 9) lies on its terminal side.

With the angle being θ, we have drawn a figure of the case. (attached)

In the right-angled triangle AOB, with respect to angle θ,

Hypotenuse: AO, Perpendicular: AB, and Base: BO

First we derive the value of AO, using the Pythagoras theorem,

AO² = AB² + BO² = 9² + 40² = 81 + 1600 = 1681 = 41²

∴ AO = 41 units.

Now we find the value of the six trigonometric functions, with respect to the angle θ.

sin θ = Perpendicular/Hypotenuse = AB/AO = 9/41

cos θ = Base/Hypotenuse = BO/AO = 40/41

tan θ = sin θ/cos θ = (9/41)/(40/41) = 9/40

cot θ = 1/tan θ = 1/(9/40) = 40/9

sec θ = 1/cos θ = 1/(40/41) = 41/40

cosec θ = 1/sin θ = 1/(9/40) = 40/9.

∴ The values of the six trigonometric functions are:

sin θ = 9/41, cos θ = 40/41, tan θ = 9/40, cot θ = 40/9, sec θ = 41/40, cosec θ = 41/9.

Answer:

The correct option is B) zero x = -2.

Step-by-step explanation:

Consider the provided graph y = x + 2

The zeros of a function are the point on which graph intersects the x axis or we can say the value of x when y = 0.

Substitute y = 0 in the provided equation.

0 = x + 2

x = -2

The coordinate is (-2,0). Also the zero of the graph is at x = -2 because it follows the definition of zeros.

Now substitute x = 0 in the provided equation.

y = 0 + 2

y = 2

The coordinate is (0,2).

Now, draw a line passing through the point (-2,0) and (0,2).

The required line is shown in figure 1.

Now consider the provided options only option A and B have the same graph.

But the correct option is B as the zero of the option B is x = -2.

Hence, the correct option is B) zero x = -2.

Explanation of graphing y=x+2 and finding its zero. Find the correct graph and x-intercept.

Graph: First, graph the equation y = x + 2. This is a straight line with a slope of 1 (rise of 1, run of 1) and y-intercept at 2.

Zero of the function: To find the zero of the function (where y = 0), set x + 2 = 0 and solve for x. In this case, x = -2.

Answer:

Final answer:

To calculate the area of triangle ABC with sides measuring 8, 11, and 15 units, Heron's formula is used. The semiperimeter s is 17 units, which leads to an area of the square root of 1836 or approximately 42.8 square units.

Explanation:

To find the area of triangle ABC with sides a = 8, b = 11, and c = 15, we can use Heron's formula, which is a method of finding the area of a triangle when you know the lengths of all three sides. The formula states that the area of a triangle is the square root of s(s-a)(s-b)(s-c) where s is the semiperimeter of the triangle, or half of the triangle's perimeter. First, we calculate the semiperimeter: s = (a + b + c) / 2. Then, we substitute the values of a, b, and c into the formula to find the area.

The semiperimeter s is (8 + 11 + 15) / 2 which equals 17. Using Heron's formula, the area is the square root of 17(17-8)(17-11)(17-15). Therefore, the area of triangle ABC is equal to the square root of 17  imes 9  imes 6  imes 2, which simplifies to the square root of 1836, resulting in an area of 42.8 square units.

Step-by-step explanation:

Please use " ^ " to denote exponentiation:  4x^2 - 12x + 9.

This 4x^2 - 12x + 9 factors into (2x - 3)^2, and is thus a perfect square trinomial.

The polynomial [tex]4x^2-12x + 9[/tex] is a perfect square trinomial. It has a binomial factor (2x - 3).

The product of a binomial by itself gives the perfect square trinomial.

A trinomial is a polynomial that has only three terms and A binomial is a polynomial that has only two terms.

A. Trinomial  [tex]4x^2-12x+9[/tex]

⇒ [tex](2x)^2-2(2x)(3)+(3)^2[/tex]

This is in the form of [tex]a^2-2ab+b^2[/tex] . So, we can write [tex](a - b)^2[/tex]

⇒ [tex](2x - 3)^2[/tex] or (2x - 3)(2x - 3)

Thus, this is a perfect square trinomial.

B. Trinomial [tex]16x^2+24x-9[/tex]

⇒ [tex](4x)^2+2(4x)(3)-(3)^2[/tex]

Since it cannot split into a binomial square, this trinomial is not a perfect square trinomial.

C. Trinomial [tex]4a^2-10a+25[/tex]

⇒ (2a)^2-2(5a)+(5)^2

This cannot be split into a binomial square, this is not a perfect square trinomial.

D. Trinomial [tex]36b^2-24b-16[/tex]

⇒ [tex](6b)^2-2(6b)(2)-(4)^2[/tex]

So, this is not a perfect square trinomial.

Therefore, the trinomial at option A is a perfect square trinomial.
