The answer is y = -6x + 15/2.

<u>First, find the slope of BC</u>.

m = Δy/Δx

m = 2 - 1 / 4 - (-2)

m = 1/6

Hence, the slope of the perpendicular bisector will be the negative reciprocal of the given line.

m' = - (1/ [1/6])

m' = -6

<u>Now, find the midpoint of BC</u>.

M = (-2 + 4 / 2, 2 + 1 / 2)

M = (1, 3/2)

Now, we can find the equation of the perpendicular bisector using the point slope form of equation.

y - y₁ = m (x - x₁)

y - 3/2 = -6 (x - 1)

y - 3/2 = -6x + 6

y = -6x + 15/2

Answer:

y = -6x + 7.5

Explanation:

To find <u>perpendicular bisector</u> equation:

Given points: B(-2, 1), C(4, 2)

First find slope:

\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

\sf slope: \dfrac{2-1}{4-(-2)}  } = \dfrac{1}{6}

Then the <u>perpendicular slope</u> will be <u>negatively inverse</u>.

\sf perpendicular \  slope \ (m) : -(\dfrac{1}{6} )^{-1} = -6

Then find the <u>mid point coordinates</u> between BC:

(x_m, y_m)= \sf (\dfrac{x_1 + x_2}{2} , \dfrac{y_2 + y_1}{2} )

(x_m, y_m) = \sf (\dfrac{-2 + 4}{2} , \dfrac{1 + 2}{2} )

(x_m, y_m) = \sf ( 1 , 1.5 )

Then find equation:

y - yₘ = m(x - xₘ)

y - 1.5 = -6(x - 1)

y = -6x + 6 + 1.5

y = -6x + 7.5

You salary 25000 with 2.5 increase
Readme [11.4K]

Answer:

25,625

Step-by-step explanation:

If your current salary is the 100%, and you get a 2.5% increase, that means the new salary would be 102.5% of 25,000. This percentage could also be written as 1.025, which you would multiply to 25,000 to get your new salary.

1.025 · 25,000 = 25,625

Therefore, your new salary would be $25,625

Sketch a graph of the polynomial function f(x) =x3− 2x2. Use it to complete the following:
AlladinOne [14]

Answer:

We have the function:

f(x) = x^3 - 2*x^2

To sketch this, we need to graph some points, and then just draw a line that passes through the points.

The graph of this equation is shown below.

Now we can complete the question.

If the graph is below the x-axis in some interval, the function is negative in that interval

If the graph is above the x-axis in some interval, the function is positive in that interval.

If the graph goes up in a interval, then the function is increasing in that interval

If the graph goes down on an interval, then the function is decreasing in that interval.

Then:

1) f is------ on the intervals (−∞, 0) and (0, 2).

Here we can see that the graph is below the x-axis in those intervals, then here we have:

f is negative on the intervals (−∞, 0) and (0, 2).

2) f is------ on the interval (2,∞)

Here the answer is positive:

f is positive on the interval  (2,∞)

3) fi is ------ on the interval (0, 4/3)

In the graph, you can see that the graph goes down in that interval, then the correct answer here is:

f is decreasing on the interval (0, 4/3)

4) f is------ on the intervals (−∞, 0) and (4/3, ∞).

In this case, we can see that the graph goes up in these intervals, then the correct answer here is:

f is increasing on the intervals (−∞, 0) and (4/3, ∞).

PLZ ANSWER THIS ASAP!! The Skywheel has 41 glass enclosed gondolas. What is the measure of each central angle between gondola ca
Aleks04 [339]

Answer:

8.78

Step-by-step explanation:

Given

n = 41

Required

The measure of central angle

Assume the gondolas are equally spaced, the central angle between each is:

Angle = 360\° \div n

Substitute 41 for n

Angle = 360\° \div 41

Angle = 8.78 ----- approximately
