Answer:
y = 3x + 2
Step-by-step explanation:
1. Work out the gradient of the line segment: change in y/change in x: -2 - -6/ -8 - 4 = 4/-12 = -1/3
2. Work out the gradient of the perpendicular bisector: the gradient of the line segment and the perpendicular bisector should multiply to get -1. This means that we can do -1 ÷ -1/3 to work out the gradient which is 3
4. Find the midpoint of the line segment: (-8 + 4) ÷ 2 = -2, and (-2 + -6) ÷ 2 = -4, so the midpoint is (-2, -4)
3. The equation will be in the format y = 3x + c and will go through (-2, -4), so we can substitute those values into the equation to find c:
y = 3x + c-4 = 3(-2) + c-4 = -6 + cc = -4 + 6c = 2The equation of the line is y = 3x + 2
Hope this helps!
For what value of k do the equation 3x 8y 0 and 6x Ky =- 16 represent coincident lines?
For what value of k = -48 the equation 3x 8y 0 and 6x Ky =- 16 represent coincident lines.
The equation 3x + 8y = 0 and 6x + Ky = -16 represent coincident lines when the two lines are identical, or when their slope and y-intercept are the same.
To find the value of k for which this is true, we can set the two equations equal to each other and solve for k.
3x + 8y = 0
6x + Ky = -16
The equation 3x + 8y = 0 represents the slope-intercept form of a line, where the slope is -3/8 and the y-intercept is 0.
The equation 6x + Ky = -16 represents the general form of a line, where the slope is -K/6 and the y-intercept is -16/K.
To find the value of k for which the two lines are identical, we need to make the slopes and y-intercepts equal.
-3/8 = -K/6
0 = -16/K
Solving for K, we get:
K = -48
So the lines are coincident when K = -48

The shape forms a pentagon. The value of y is 84°.
What is a polygon?
In geometry, a polygon is any closed curve made up of a series of line segments (sides) joined so that no two segments cross. Triangles (three sides), quadrilaterals (four sides), and pentagons are the simplest polygons (five sides).
The shape ABCDE forms a petagon.
The interior angle of a pentagon is 108°
The interior angle of a hexagon is 120°.
The ∠ABC is an angle of a regular hexagon, thus ∠ABC = 120°.
The ∠BCD is the angle of a regular hexagon, thus ∠BCD =120°.
The ∠BAE is an angle of a regular pentagon, thus ∠BAE=108°.
The ∠AED is an angle of a regular pentagon, thus ∠AED=108°.
The sum of all interior angle of a pentagon is 540°
Therefore,
∠ABC + ∠BCD + ∠BAE + ∠AED +∠EDC = 540°
120° + 120° + 108° + 108° + y = 540°
456° + y = 540°
y = 540° - 456°

Calculate the geometric mean return of the following data set: (Negative value should be indicated by a minus sign. Round your intermediate calculations to 4 decimal places and final answer to 2 decimal places.)
The geometric mean return of the given data set is 0.02.
The geometric mean return measures the compound rate of return over a period of time. It is calculated by taking the product of all the returns and then taking the nth root of the product, where n is the number of returns.
Formula: GMR = ((1+r1)(1+r2)…(1+rn))^1/n – 1
In this case, the data set is as follows:
r1 = 0.05
r2 = 0.03
r3 = -0.02
Using the formula above, the geometric mean return is calculated as:
GMR = ((1+0.05)(1+0.03)(1-0.02))^1/3 - 1
GMR = ((1.05)(1.03)(0.98))^1/3 - 1

Using the property of exponents, the value of x for the formula 3x=729 is 6.
What is exponents?The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. 2 x 3 = 6 does not equal 23. Keep in mind that a number raised to the power of one is itself. Exponentiation is the process of expressing huge numbers in terms of powers. That is, exponent refers to the number of times a number has been multiplied by itself. For example, 6 is multiplied by itself four times, yielding 6 6 6 6. This is written as 64.
