Answer:

2 1/2 (or 2 3/6)

Step-by-step explanation:

\(\frac{Numerator}{Denominator}\)

both denominators are the same so you can just subtract 2 from 4 and also the numerators which are 2 and 5.

4 - 2 = 2

5/6 - 2/6 = 3/6

so the answer is 2 3/6 which simplifies to 2 1/2

Given:

In △ABC is a right angle triangle.

AC is 6 units longer than side BC.

\(Hypotenuse=2\sqrt{17}\)

To find:

The length of AC.

Solution:

Let the length of BC be x.

So, Length of AC = x+6

According to the Pythagoras theorem, in a right angle triangle

\(Hypotenuse^2=Base^2+Perpendicualar^2\)

△ABC is a right angle triangle and AC is hypotenuse, so

\((2\sqrt{17})^2=(x)^2+(x+6)^2\)

\(68=x^2+x^2+12x+36\)            \([\because (a+b)^2=a^2+2ab+b^2]\)

Subtract 68 from both sides.

\(0=2x^2+12x+36-68\)

\(0=2x^2+12x-32\)

\(0=2(x^2+6x-16)\)

Divide both sides by 2.

\(x^2+6x-16=0\)

Splitting the middle term, we get

\(x^2+8x-2x-16=0\)

\(x(x+8)-2(x+8)=0\)

\((x+8)(x-2)=0\)

\(x=-8,2\)

Side cannot be negative, so x=2 only.

Now,

\(AC=x+6\)

\(AC=2+6\)

\(AC=8\)

Therefore, the length of AC is 8 units.

Using a standard normal distribution table, we find that the probability is approximately 0.0134 (rounded to four decimal places).

Probability is a measure of the likelihood or chance that a particular event or outcome will occur. It is expressed as a value between 0 and 1, where 0 represents an event that is impossible to occur, and 1 represents an event that is certain to occur.

To solve this problem, we can use the formula for the standard deviation of the sample mean:

Standard deviation of sample mean = standard deviation / √(sample size)

Plugging in the given values:

Standard deviation of sample mean = 7 / √(31)

Next, we can calculate the z-score, which is the number of standard deviations the sample mean is below the population mean:

z-score = (sample mean - population mean) / standard deviation of sample mean

Plugging in the given values:

z-score = (141.5 - 145) / (7 / √(31))

Using a calculator, we find that the z-score is approximately -2.22.

Finally, we can use a standard normal distribution table or a calculator to find the probability that a z-score is less than -2.22.

Using a standard normal distribution table, we find that the probability is approximately 0.0134 (rounded to four decimal places).

In this case, we can identify two similar triangles like this:

Since VX is a bisector of ZC it cuts ZC into two equal-length segments, then ZY and YC have the same length and we can formulate the following expression:

ZY = YC

ZY = 18

Since we are dealing with similar triangles, we can formulate the following expressions for VYZ and ZYX:

By replacing 18 for ZY and 27 for XY, we get:

By multiplying both sides by 18, we can solve for 18, to get:

By adding the length of VY to the length of XY, we get:

VY + XY = 12 + 27 = 39

Adding VY to XY we should get VX, which is the diameter of the circle. Then VX = 39

Yeah, you're right.

The answer to the expression is  (x+3)/(x-1)

You should recall that a quadratic expression is an algebraic expression of the form ax2 + bx + c = 0, where a ≠ 0

The given expressions are

(x² - 3x - 18) / (x²- 7x +6

(x²-6x +3x +19) / (x²-x -6x +6)

This implies that {(x²-6x)+(3x-18)} / {(x²-x) -(6x+6)}

⇒[x(x-6)+3(x-6)] / [x(x-1) - 6(x-1)]

This means that [(x+3)(x-6)] / [(x-6)(x-1)]

Dividing by (x-6) to have

Therefore the value of the expression is (x+3)/(x-1)

To determine the area of the remaining piece of cardboard expressed in terms of x when a square of side length x inches is cut out from a rectangular piece of cardboard having a length of 6x+2 inches and a width of 2x-4 inches, use the following steps.

Draw and label a diagram of the problem. The rectangle should be labeled as 6x+2 inches by 2x-4 inches, and the square cut out should be labeled as x inches by x inches. This is how the diagram looks like: Determine the area of the rectangle, Arect.

The area of the rectangle is given by the product of its length and width. Thus, Arect = (6x + 2)(2x - 4) Determine the area of the square, Asq. The area of the square is given by the square of its side length. Thus, Asq = x²Step 4: Determine the area of the remaining cardboard after the square is cut out, Ar.

This is the difference between the area of the rectangle and the area of the square. Thus, Ar = Arect - Asq= (6x + 2)(2x - 4) - x²= 12x² - 20x - 16

Simplify the expression. The final answer is given in terms of x. Thus, Ar = 12x² - 20x - 16.The area of the remaining piece of cardboard is expressed in terms of x as 12x² - 20x - 16.

Answer:

answer is B tho i jus know

Step-by-step explanation:

The piecewise function can be defined as, f(x) = x+3, if x<0 and f(x) =3, if  x≥0, Option B is correct.

A relation is a function if it has only One y-value for each x-value.

From the given figure it is easily noticed that the function is increasing in nature for x<0 and the function is constant in nature for x>0 because the value of y remains unchanged for any value of x, where x≥0

The value of function is 3 at x=0.

The value of the function is always 3 for all x≥0 .

f(x)=3 for x≥0

The function is a straight line with intercepts (-3,0) and (0,3).

slope = 3-0/0+3

=1

Let us find the y intercept

0=1(-3)+b

b=3

Now equation is y=x+3

For x<0, the function is,

f(x)=x+3

Therefore the piecewise function can be defined as, f(x) = x+3, if x<0 and f(x) =3, if  x≥0.
