To prove that BH = CK in triangle ABC, we can use the angle bisector theorem. The theorem states that the angle bisector of an angle in a triangle divides the opposite side into two segments proportional to the other two sides. By applying this theorem and representing BH as x and CK as y, we can show that x = y, thus proving that BH = CK.

In triangle ABC, to prove that BH = CK, we can use the angle bisector theorem. Since m∠B = m∠C, the angle bisector of ∠B will divide the side AC into two segments proportional to the other two sides. Let's denote BH as x and CK as y. According to the angle bisector theorem, we have:

Since AB = AC (isosceles triangle), we can rewrite the first equation as:

x / BC = AH / HC

And the second equation as:

AC / BC = AK / y

Since AB = AC, we can substitute AC with AB:

x / BC = AK / y

Now, we can cross-multiply and solve for x and y:

x * BC = AK * HC

y * BC = x * HK

Simplifying, we get:

x = AK * HC / BC

y = x * HK / BC

Since HK = HC, we have:

x = AK

y = x

Therefore, BH = x = CK = y.

It is true that the product of a complex number and its conjugate is a real number and this can be determined by using arithmetic operations.

Let the complex number be (a + bi). Therefore, its conjugate is given by (a - bi).

The following calculation can be used to determine the product of a complex number and its conjugate:

= (a + bi).(a - bi)

Multiply (a) by (a - bi) and then multiply (bi) by (a - bi) in the above expression.

[tex]\rm =a^2-abi+abi-b^2i^2[/tex]

Simplify the above expression.

[tex]\rm =a^2-b^2i^2[/tex]

Remember the value of ([tex]\rm i^2 = -1[/tex]). So substitute the value of [tex]\rm i^2[/tex] in the above expression.

[tex]\rm = a^2+b^2[/tex]

From the above calculation, it can be concluded that it is true that the product of a complex number and its conjugate is a real number.

The required equation of the line is y = 3x which passes through the origin with the slope 3.

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

We have to determine the equation of the line that passes through the origin with slope 3.

Let's assume slope-intercept form:

So required line in the slope-intercept form is:

y = mx + b

where m is the slope and b is the y-intercept.

In this case, the slope of line m = 3, and the line passes through the origin

So, therefore equation will be:

y = 3x + 0 or

y = 3x

Thus, the required equation of the line is y = 3x which passes through the origin with the slope 3.

Generally, whenever a point (x,y) is reflected across the y axis, the y coordinate stays the same and the sign of x coordinate changes.

So [tex](x,y)[/tex] changes to [tex](-x,y)[/tex].

Point D in the diagram shown has coordinates [tex](3,-1)[/tex]. According to the rule, the x-coordinate, 3, will change to -3 and the y-coordinate, -1, would stay the same.

Hence, our image of D after the reflection about y-axis would have coordinates [tex](-3,-1)[/tex].

Answer:

29 4/25 square inches (not given in the options)

Step-by-step explanation:

A square is a plain 4 sided shape with equal sides. As such, all sides of a square are equal. If the length o a side of a square is s, the area of the square will be s² while the perimeter will be 4s.

Area of square = (5 2/5 inches)²

= (27/5 inches)²

= 729/25 square inches

= 29 4/25 square inches

Answer:

Range.

Step-by-step explanation:

Alan must use the measure called Range, which indicates the dispersion between the extreme values of a variable. It is calculated as the difference between the highest and the lowest value of the variable. It is denoted as R. First the data is sorted, then it is calculated as:

R = x (n) - x (1) where,

x (n): It is the largest value of the variable.

x (1): It is the smallest value of the variable.

In the given case (5, 6, 7, 5, 7, 9, 2, 4, 8, and 7), we sort the data, and get,

2, 4, 5, 5, 6, 7, 7, 7, 8, 9

x (n) = 9

X (1) = 2

R = 9 - 2 = 7

Answer: The value of angle Y is 75 ° .

Step-by-step explanation:

Given Δ ABC ≈ Δ XYZ

∠ A = 45°

∠ C = 60°

To find =

∠Y =? in ΔXYZ

Solution:

In Δ ABC

∠ A = 45 °

∠ C = 60 °

∠ B = ?

∠ A + ∠ C +∠ B = 180 ° (angle sum property of triangle)

∠ B = 75 °

Since, given that Δ ABC ≈ Δ XYZ and in similar triangles ,angles of respective vertices are equal. As shown in the image attached

∠ A = 45 ° = ∠ X

∠ B = 75 ° = ∠ Y

∠ C = 60 ° = ∠ Z

So, the value of angle Y is 75 ° .

Answer:

The equivalent equation of [tex]d=\frac{m}{V}[/tex] is [tex]V=\frac{m}{d}[/tex].

Step-by-step explanation:

The given equation is

[tex]d=\frac{m}{V}[/tex]

Where d is density, m is mass and V is volume.

We have to solve this equation for V. To separate the variable V on one side multiply both sides by V.

[tex]d\times V=\frac{m}{V}\times V[/tex]

[tex]dV=m[/tex]

Diven both sides by d.

[tex]\frac{dV}{d}=\frac{m}{d}[/tex]

[tex]V=\frac{m}{d}[/tex]

Therefore the equivalent equation of the given equation is [tex]V=\frac{m}{d}[/tex].

The equation of the line passing through point P(0, 0) and perpendicular to the line y = -9x-1 is y = (1/9)x, with the slope of the line being the negative reciprocal of -9.

To write an equation of the line passing through point P(0, 0) that is perpendicular to the line y = −9x−1, we first identify the slope of the given line. The slope of the line y = −9x−1 is −9, so the slope of a line perpendicular to it will be the negative reciprocal. Therefore, the perpendicular slope is 1/9.

Since the point P(0, 0) is also the y-intercept, we can directly write the equation of the perpendicular line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Thus, the equation of the line we are looking for is y = (1/9)x.
