Answer:

Step-by-step explanation:

An inequality that can be written in the form ax + by < c (where a and b are not both zero) is called a linear inequality in two variables.

An inequality that represents a line in a two-dimensional coordinate system is referred to as a linear inequality. The set of points that satisfies the inequality is a half-plane bounded by a line that may be dashed or solid.

In contrast to a linear equation, which represents a line, a linear inequality represents a half-plane. The points on one side of the line, rather than the points on the line, are solutions to the inequality.

The method of shading is used to graph a linear inequality in two variables. First, graph the boundary line, which is usually represented by a solid or dashed line, and then select a test point on one side of the line. Shaded regions of the half-plane containing the test point satisfy the inequality.

The expression without using absolute value is 2z - 11

Given the expression with absolute value expressed as:

lz-6l-lz-5l

Since absolute function can both be negative or positive, hence;

lz-6l-lz-5l = z - 6 - -(z - 5)

lz-6l-lz-5l = z-6-(-z+5)

lz-6l-lz-5l = z - 6 + z - 5

lz-6l-lz-5l = 2z - 11

Hence the expression without using absolute value is 2z - 11

The portion of the ECG that corresponds to repolarization of the atria is not usually visible on a standard ECG. In some cases, abnormalities in the repolarization of the atria may be visible on an ECG as changes in the shape or duration of the T wave.

The standard ECG only records electrical activity that is strong enough to cause depolarization of the ventricles, which creates the QRS complex. The repolarization of the atria occurs during the T wave, which represents ventricular repolarization. Therefore, the repolarization of the atria is usually hidden within the T wave and cannot be specifically identified on a standard ECG.

The electrical activity of the heart is recorded on an ECG as a series of waves and intervals that correspond to specific events in the cardiac cycle. The P wave represents the depolarization of the atria, which causes them to contract and pump blood into the ventricles. The QRS complex represents the depolarization of the ventricles, which causes them to contract and pump blood out of the heart. The T wave represents the repolarization of the ventricles, which allows them to relax and refill with blood. During the cardiac cycle, the repolarization of the atria occurs after their depolarization and contraction. This repolarization wave is very small and weak compared to the depolarization wave, and it is not usually visible on a standard ECG. Instead, the repolarization of the atria is hidden within the T wave, which represents the larger and more prominent repolarization wave of the ventricles.

Answer:

Q6: 5 times the sum of 3 and 4, then subtract 4.

Q7: Add 8 to half the difference of 6 and 2, then subtract 1.

Step-by-step explanation:

\(5 \times (3 + 4) -4\)

• First of all, we can see that 5 is being multiplied by something, so we can say "5 times...".

• Next we see that the 5 was being multiplied by the sum of 3 and 4, so we can combinedly say "5 times the sum of 3 and 4...".

• And finally, we see that 4 is taken away from the result. Therefore we can say " 5 times the sum of 3 and 4, then subtract 4".

\(8 + \frac{1}{2} \times (6-2) -1\)

• Firstly, we can see that 8 is being added to something, so we can say "Add 8...".

• Next, we see that 8 was being added to \(\bf \frac{1}{2}\) of something, so we can combinedly say "Add 8 to half of...".

• Then we see that the difference (i.e., result of subtraction) of 6 and 2 was being halved. Therefore we say "Add 8 to half of the difference of 6 and 2...".

• Finally, we can see that 1 is subtracted from the result. Therefore, we can say "Add 8 to half of the difference of 6 and 2, then subtract 1".

Answer:

Y=-1/2x+1 because b=the y intercept or in other words, the point at which the line crosses the y axis which is at 1. -1/2x because m=the slope and since the line is going down the slope would be negative. Remember rise/run rule, to get to the next point from (0,1) the line goes down 1 and over 2 which would make it 1/2 and since it goes down it is -1/2. The x stays because that is the variable in which you substitute numbers in for to get new points. Thus the y=Mx+b that you are looking for is y=-1/2x+1

Step-by-step explanation:

The required value of y for the unit circle is: 2/3

The circle is defined as the locus of a point whose distance from a fixed point is constant i.e center (h, k).

The equation of the circle is given by:

(x - h)² + (y - k)² = r²

where:

h, k is the coordinate of the center of the circle on coordinate plane.

r is the radius of the circle.

Here,

Equation of the unit circle is given as,

x² + y² = 1

Now substitute the given value in the equation,

5/9 + y² = 1

y² = 1 - 5/9

y² = 4/ 9

y = √(4/9)

y = 2/3

Thus, the required value of y for the unit circle is 2/3

So, the equation is:

The equation of the plane passing through the origin and the points (3, -4, 6) and (6, 1, 4) is: 3x + 18y + 12z = 0.

Assuming a plane can be defined by a normal vector and a point on a plane;

Let's find the normal vector on the plane.

Taking the cross product of the two plane

Vector AB = (3, -4, 6) - (0, 0, 0) = (3, -4, 6)

Vector AC = (6, 1, 4) - (0, 0, 0) = (6, 1, 4)

Normal vector = AB × AC = (3, -4, 6) × (6, 1, 4)

Using determinant method, the cross product is;

i   j   k

3  -4   6

6   1   4

Evaluating this;

i(4 - 1) - j(6 - 24) + k(18 - 6)

= 3i - (-18j) + 12k

= 3i + 18j + 12k

The normal vector on the plane is calculated as; (3, 18, 12).

Using the normal vector and the point that lies on the plane, the equation of the plane can be calculated as;

The general form of an equation on a plane is Ax + Bx + Cz = D

Plugging the values

3x + 18y + 12z = D

Substituting (0, 0, 0) into the equation above and solve for D;

3(0) + 18(0) + 12(0) = D

D = 0

The equation of the plane is 3x + 18y + 12z = 0

In geometry, the diameter of a circle is any linear fashion segment that has an endpoint mostly on circle and travels through its centre. Another way to put it is the tallest chord of a circle

The diameter of the circle is represented by the line segment AB. This is due to the fact that it runs through the centre H and connects two points on the circle.

The radius of the circle is represented by the line segment AH. This is because it connects the circle's centre H to a point A.

The chord is the line segment. The chord CD is a circle chord. This is due to the fact that it connects two points on a circle but does not pass through the centre.

Tangent to the circle: The line segment EF is tangent to the circle. This is due to the fact that it only intersects the circle at one point, G, and is perpendicular to the radius GH at that point.

ABG's curve is an arc of the circle. This is because it is part of the circle's circumference, connecting two points A and B.

A random variable is with an unknown value or a function that gives values to each of the results of an experiment.

Random variables are frequently identified by letters and fall into one of two categories: continuous variables, which can take on any value within a continuous range, or discrete variables, which have specified values.

Continuous random variables have an endless number of possible values and can represent any value that falls within a given range or interval.

The fraction nonconforming for this sample is 0.112, or 11.2%.

This is the value that the QC inspector can use to create a p-chart for analyzing the gears' non-conformance.

To calculate the fraction nonconforming, we'll use the following formula:
Fraction nonconforming = Number of nonconforming items / Total sample size
In this case, the number of nonconforming items is 28 gears, and the total sample size is 250 gears.

Now, let's plug in the numbers:
Fraction nonconforming = 28 / 250
Now, we'll divide 28 by 250:

Length = Breadth + 5cm = 13cm + 5cm = 18cm

Area = Length x Breadth

Area = 13 x 18 = 234\(cm^{2}\)

Answer:

Step-by-step explanation:

Here, the breadth is 5 cm less than the length of the rectangle.

Let, the length = x cm

 So, the breadth = (x-5) cm

given,

         x - 5 = 13

 or,  x = 18 cm

so the length = 18 cm

Area = length × breadth

         = 18 × 13
