The possible value of n in the triangle given is, n < 3x+5

The triangle is a polygon with three side, vertex, and angles.

Given that, a triangle has side lengths measuring 2x + 2 ft, x + 3 ft,

and n ft.

We asked to find the expression that represents the possible values of n.

We know that,

The sides of a triangle rule assert that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

Therefore,

2x+2+x+3 = 3x+5

Thus, the possible value of n is,

n < 3x+5

Hence, the possible value of n in the triangle given is, n < 3x+5

Method 1

Here, we make use of the cosine rule

So, we have

cos(45) = x/283

So, we have

x = 283 * cos(45)

Evaluate

x = 200.11

Method 2

Here, we make use of the sine rule

The sine can be calculated as

When x + y = 90;

sin(x) = cos(y)

When the distribution is normal, we use the z-score formula.

Z = (X - μ)/σ

We have σ = 0.15 and units with weights less than 9.85 or greater than 10.15 ounces will be classified as defects.

μ = 10.15 - 0.15 = 9.85 + 0.15 = 10

Now, the probability that a unit is defective.

P(X ≥ 10.15)

Given piecewise function has a jump discontinuity at 0 or x=0 i.e. B.

What exactly is a piecewise function?

A piecewise function is one that has multiple definitions in different x intervals. A piecewise function's graph is divided into parts that correspond to each of its definitions. A very excellent example of a piecewise function is the absolute value function. Let us investigate why it is thus named. We know that an absolute value function is defined as f(x) = |x|.

f(x)=(x if x≥0 ,

     -x  if x><0)

This piecewise function should be interpreted as

When x is higher than or equal to 0, f(x) equals x.

When x is less than zero, f(x) equals -x.

Now,

As jump discontinuity is defined as where the endpoint of one segment and the start of the following segment may have the same x coordinate but have different values of f(x). In the piecewise linear function, such a difference is known as a jump discontinuity.

Answer:

A. B is correct

B. A is correct

C. B is correct

Step-by-step explanation:

Area of triangle: A = 1/2bh

A. Area of each triangle: A = 1/2 x 11.5 x 12 = 69

Total surface areas = 4(area of triangle) + area of square = 4(69) + 12^2 = 420

So A is incorrect and B is correct

B. Area of triangle: A = 1/2 x 13.9 x 16 = 111.2

Surface area = 4(area of triangle) = 4(111.2) = 444.8

So A is correct and B is incorrect

C. Area of triangle with base of 10: A = 1/2 x 10 x 7 = 35

Area of triangle with base of 8.1: A = 1/2 x 8.1 x 16 = 64.8

Total surface areas = 2(area of triangle base of 10) + 2(area of triangle base of 8.1) + area of rectangle = 2(35) + 2(64.8) + (10x8.1) = 280.6

So A is incorrect and B is correct.

Based on the information, the integer used will be (10 - 4). The difference is 6.

On a number line, there'll be 6 units between the numbers

To find the difference between two integers by adding the additive inverse, we can follow these steps:

Subtract the smaller integer from the larger one: (larger integer) - (smaller integer).

Take the absolute value of the result to get the distance between the two integers on a number line.

The distance between two integers is the absolute value of the difference, so we do not include the sign in our answer. The answer will always be a non-negative number.

Answer: A quarter is worth $0.25 and a dime is worth $0.10, so the total amount of money Alonso has can be represented by the expression 0.25x + 0.1y. To find one possible solution to the system of inequalities, we need to find the values of x and y that satisfy both the inequality 0.25x + 0.1y ≥ 3.60 and the inequality y ≥ 0.

The inequality 0.25x + 0.1y ≥ 3.60 represents all points (x, y) that are on or above the line 0.25x + 0.1y = 3.60. The inequality y ≥ 0 represents all points (x, y) that are above or on the x-axis. The intersection of these two regions is the solution set of the system of inequalities, which represents all points (x, y) that satisfy both inequalities.

To graph the solution set, we can start by plotting the line 0.25x + 0.1y = 3.60 and shading the region above the line. Then, we can plot the x-axis and shade the region above the x-axis. The intersection of the two shaded regions is the solution set.

One possible solution to the system of inequalities is the point (14, 4). This means that Alonso has 14 quarters and 4 dimes, which total $3.60. However, there may be other solutions to the system of inequalities that would also satisfy the conditions.

The difference between a right circular cylinder and a cylinder is that a right circular cylinder has a circular base and is perpendicular to the base, whereas a cylinder can have any shaped base and the sides do not have to be perpendicular to the base.

A right circular cylinder has a circular base and its sides are perpendicular to the base, forming a right angle. This means that the axis of the cylinder is at a right angle to the base.

On the other hand, a cylinder can have any shaped base, such as a rectangle or an ellipse, and the sides do not have to be perpendicular to the base. This means that the axis of the cylinder can be at any angle to the base.

In summary, the main difference between a right circular cylinder and a cylinder is the shape of the base and the angle of the sides to the base. A right circular cylinder has a circular base and perpendicular sides, while a cylinder can have any shaped base and the sides can be at any angle to the base.

The formula for sine rule is sinA/a=sinB/b=sinC/c

Given that, in ΔXYZ, ∠X=17° and ∠Y=82°. ∠XWZ=90° and XY=700.

By using angle sum property,

∠X+∠Y+∠Z=180°

Answer:

h = 10.0708 cm

Area of shaded region = 8.1841 [tex]cm^{2}[/tex]

Step-by-step explanation:

r = radius of circle

 = 14 cm

h = perpendicular height of triangle

Use SinФ trigonometric function to determine h

SinФ = [tex]\frac{Opposite}{Hypotenuse}[/tex]

Sin46° = [tex]\frac{h}{14}[/tex]

Cross-multiplication is applied:

∴h = (14)(Sin46°)

   h = 10.0708 cm (Rounded to four decimal places)

Area of sector = [tex]\frac{AngleOfSector}{360^{o}}[/tex] × ([tex]\pi r^{2}[/tex])

                         = [tex]\frac{46}{360}[/tex] × [tex]\pi (14^{2})[/tex]

                         = [tex]\frac{9016}{360} \pi[/tex] [tex]cm^{2}[/tex]
                         = 78.68 [tex]cm^{2}[/tex]

Area of triangle = [tex]\frac{1}{2}[/tex] × (Base of triangle) × h

                           = [tex]\frac{1}{2}[/tex] × (14 cm) × [(14)(sin46°)]
                           = (98)(sin46°)

                           = 70.50 [tex]cm^{2}[/tex]

The measure of angle x needs to be increased by 200, the new angle would be the original measure of angle x plus 200 degrees.

What is the angle measurement?

A radian is the length of an arc formed by an angle that, when shown as a central angle, equals the length of the circle's radius.

If the measure of angle x needs to be increased by 200, we can simply add 200 to the original measure of angle x to find the new angle.

So, if the original measure of angle x is, for example, 30 degrees, the new angle would be:

New angle = 30 degrees + 200 degrees

New angle = 230 degrees

Therefore, if the measure of angle x needs to be increased by 200, the new angle would be the original measure of angle x plus 200 degrees.
