Given that P is a point on the perpendicular bisector, l, of MN, we have proved that PM = PN because By the definition of reflection, point P is the image of itself and point N is the image of N.

We are given :

P is a point on the perpendicular bisector, l, of MN.

Now, we want to prove that PM = PN

A Reflection is a transformation in which the figure is the mirror image of the other. Every point is a mirror reflection of itself .

By the definition of reflection, we can deduce that point P is the image of itself , and point N is the image of M .

The line l acts as a Line of symmetry or axis of reflection.

Now, in transformations, we know that reflections preserve length and as a result, PM = PN.

Therefore, we will conclude that point N is the image of M .

The zeros of the function f(x) = x³ + 9x² + 20x  is :

0, 5 ,4

Steps to solve quadratic equation:

Check your answer by plugging it into the original equation.

Given function,

f(x) = x³ + 9x² +20x

take x common from f(x),

=> x(x² + x - 20) = 0

=> x(x² + 5x + 4x + 20) = 0

=> x( x + 5 ) + 4 ( x +5 ) = 0

=> (x + 5)  ( x + 4 ) = 0

=> x -5 = 0 or x -4 = 0

=> x = 5 and x = 4 .

Answer:

y = 1/3 x + 3

Step-by-step explanation:

1) when finding a perpendicular line, you take the slope and use the reciprocal (you flip it) and change the sign (from negative to positive or positive to negative)

-3 ---> 1/3

2) plug in the slope into a new equation

y=1/3 x + b

3) plug in the points

3= 1/3 (0) + b

b=3

4) rewrite the equation

y=1/3 x + 3

The equation is of the form y=mx+b, where m = slope and b = y-interset. Therefore, find m and b:

For m

For b

So, the equation is:

Step-by-step explanation:

You want the value of c(3) when c(x) = (x -5)^3.

The value of a function is found by substituting the argument for the variable and doing the arithmetic.

  c(x) = (x -5)^3

  c(3) = (3 -5)^3 = (-2)^3

  c(3) = -8

Answer:

You cant use the distributive property because it is when the equation is like this: ax(b+c) so if it was 11x(5+0) you would multiply the 5 by 11 by itself and multiply 0 with 11 then you add them and get 55. I hope that helps :)

Step-by-step explanation:

The mean = 0.2,  variance = 0.03226 and Standard deviation = 0.1796

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

level            x

1             0.419

2            0.276

3            0.225

4            0.068

5            0.012

So, mean = (0.419+ 0.276 + 0.225+ 0.068 + 0.012)/5

mean = 0.2

level          x        (x- mean)       (x- mean)²        

1             0.419        0.219            0.0479  

2            0.276       0.076            0.0057

3            0.225        0.025         0.000625

4            0.068       -0.268         0 .0718

5            0.012        -0.188          0.0353

So, variance = 0.032265

standard deviation = √(variance)

Standard deviation = √(0.032265)

Answer:

P(A|B) =  1/2

Step-by-step explanation:

Sample space for B = {10, 20, 30, 40, 50, 60, 70, 80}

where B is even

Total number of elements in sample space = 8

P(A|B) = Probability of a number being 40 or less from the sample space of 8

Sample space for A|B  = {10, 20, 30, 40}

So out of a possible 8 elements in the sample space for B only 4 elements can be chosen for the sample space of A

So P(A|B) = 4/8 = 1/2

Lowest degree polynomial with f(0) = 960 with zeros of -4 (multiplicity 3), 3(multiplicity 1). The polynomial is f(x)=-5(x+4)³(x-3).

Given that,

Lowest degree polynomial with f(0) = 960 with zeros of -4 (multiplicity 3), 3(multiplicity 1)

We have to find the polynomial of f(x) which satisfy the conditions.

Here,
We have the zeros of the polynomial are -4 (multiplicity 3), 3(multiplicity 1)

Which we can write as -4,-4,-4,3 are the zeros.

Then we can write the polynomial as

f(x)=ω(x+4)³(x-3)

We have to first find the value of ω.

So,

We have f(0)=960

ω(0+4)³(0-3)=960

ω(4)³(-3)=960

64ω(-3)=960

-192ω=960

ω=960/-192

ω=-5

We got the ω as -5.

The polynomial f(x)=-5(x+4)³(x-3)

Therefore, the polynomial is f(x)=-5(x+4)³(x-3).

An equation of the line in point-slope form is y = 6x + 50.

y = y₁ = m(x -x₁) is the equation of a straight line, where m is the slope and (x₁, y₁) are the coordinates at a given point on the line (see slope-intercept form). When you know the slope and another point on the line, the point-slope form of a linear equation is most helpful for locating a point on a line. When two other points are known, it can also be used to locate a point on a line.

Given,

y₂ = 200

y₁ = 230

x₂ = 30

x₁ = 25

Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Slope = [tex]\frac{230-200}{30-25}[/tex]

Slope = [tex]\frac{30}{5}[/tex]

Slope = 6

Equation:

y - y₁ = m(x - x₁)

y - 200 = 6(x - 25)

y - 200 = 6x - 150

Answer:

  $1258.09

Step-by-step explanation:

You want the monthly annuity payment that will let you withdraw $150,000 per year forever from an account earning 8% after 30 years.

In order to withdraw an amount "forever," the withdrawal amount must be equal to the interest earned by the account.

  I = Prt

  150,000 = P(0.08)(1)

  P = 150,000/0.08 = 1,875,000

The value of an ordinary annuity is given by the formula ...

  A = P(12/r)((1 +r/12)^(12t) -1) . . . . . where P is the monthly payment, and r is the annual interest rate earned over a period of t years.

Using the values we know, we can find P:

  1875000 = P(12/0.08)((1 +0.08/12)^(12·30) -1) = 1490.359449P

  P ≈ 1258.09

You would need to deposit $1258.09 each month.

The formulas used here assume that the deposits and withdrawals occur at the end of the month.

Based on the fact that the researchers are 96% confident that they are correct, then the probability that they are actually wrong is 4%.

If we are to believe the assertions of the researchers that they are 96% certain of them being correct, then the probability that they are wrong can be found by the formula:

= 1 - Percentage certainty

Solving for that probability of being wrong then gives:

= 1 - 96%

= 4%

It is worthy of note that this probability of being wrong is based on their estimates and so there is a chance that the probability of being wrong is 4%.
