EXPLANATION

We want to find the equation of the perpendicular bisector of the line segment with the given endpoints.

To do this, we first have to find the slope of the given line, since the slope of a line perpendicular to a given line is the negative inverse of the slope of the line.

Then, we have to find the midpoint of the given line since the line is a bisector, it passes through the midpoint of the given line segment.

To find the slope of the line, apply the formula for the slope of a line:

where (x1, y1) and (x2, y2) are the two endpoints of the line segment

Hence, the slope of the line is:

The negative inverse of this is:

To find the midpoint of the endpoints, apply the formula for midpoint:

Hence, the midpoint of the given endpoints are:

Now, we have the slope and an endpoint of the perpendicular bisector.

To find the equation of the line, we have to apply the point-slope method:

Therefore, the equation of the perpendicular bisector of the line segment is:

Given a normal distribution with m = 100 and s = 10, the probabilities are;

a) X > 75 = 0.0062

b) X < 70 = 0.00135

c) X < 80 or X > 110 = 0.053954

We are given;

Population mean; m = 100

standard deviation; s = 10

The z-score is gotten from the formula;

z = (X - m)/s

Thus;

1) Probability that X > 75 is;

z = (75 - 100)/10

z = -2.5

From online p-value from z-score calculator, we have;

probability = 0.0062

2) Probability that X < 70 is;

z = (70 - 100)/10

z = -3

From online p-value from z-score calculator, we have;

probability = 0.00135

3) Probability that X < 80 is;

z = (80 - 100)/10

z = -2

From online p-value from z-score calculator, we have;

probability = 0.02275.

Probability that X > 110 is;

z = (110 - 100)/10

z = -1

From online p-value from z-score calculator, we have;

probability = 0.158655

Thus, P(0.02275 < x < 0.158655) = 0.053954

Given the question on the question tab;

Explanation:

Final answer:

The plotted function and the function y = 3x - 6 represent a straight line and have have same slope and hence, both the lines are parallel to each other.

The general equation of a straight line is of the form -

y = mx + c

where -

[m] is slope of line

[c] is y - intercept

Given is a equation of a straight line and a graph of a straight line.

We have the following equation -

y = 3x - 6

For this equation, the slope of the straight line will be [m] = 3 and the y - intercept would be [c] = - 6. Refer to the graph attached with green color for all the possible set of solution.

Now, the equation of the line plotted on graph -

m = (4 - 0)/(0 + 1.3)

m = 3.07

m = 3 (approx.)

Its y - intercept [c] = 4

Therefore, the equation of the plotted line -

y = 3x + 4

Now, both the lines are plotted on the graph. It can be seen from the graph and from the equation that they have same slope and hence, both the lines are parallel to each other.

Therefore, the plotted function and the function y = 3x - 6 represent a straight line and have have same slope and hence, both the lines are parallel to each other.

1. The decrease in dollars, based on a 7.5 percent decrease, is $615.

2. The balance in the account at the end of last year was $7,585.

A percentage is a ratio or proportion of a variable in another.

For instance, the percentage decrease in the investment account was 7.5%, which in dollar terms amounts to $615.

The percentage reference gives an idea of the investment status and the fractional effect that the decrease had on it.

Initial investment = $8,200

Decrease in investment = 7.5%

Decrease in dollars = $615 ($8,200 x 7.5%)

Balance = $7,585 ($8,200 - $615)

Thus, Tammy's investment account decreased to $7,585 by $615, representing a 7.5% decrease.

The quadratic function in vertex form is y = -1/2(x + 1)^2 - 2

The vertex is given as

(h, k) = (-1,-2)

The point is also given as

(x, y) = (3, -10)

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

Substitute (h, k) = (-1,-2)  in y = a(x - h)^2 + k

y = a(x + 1)^2 - 2

Substitute (x, y) = (3, -10)

-10 = a(3 + 1)^2 - 2

So, we have

-10 = a(4)^2 - 2

Add 2 to all sides

-8 = a(16)

Divide by 16

a = -1/2

Substitute a = -1/2 in y = a(x + 1)^2 - 2

y = -1/2(x + 1)^2 - 2

Hence, the equation is y = -1/2(x + 1)^2 - 2

The type of function we are going to work with here is an exponential function. These functions are given by equations like:

Where x is the variable and a, b and c fixed parameters. In this case c=0, a=1 and b=13/4. This number b, i.e. the one affected by the exponent is called the base so I'm going to refer to it with that word.

All exponential functions have similar graphs, they pass from being very close, almost pararel to the x-axis and then they begin to rapidly increase toward infinite y values. In the following picture you can see the graph of two exponential functions:

The red graph tends to zero for positive x values, this means that its equation has a negative sign in the exponent:

The blue graph on the other hand tends to zero for negative x values which means that there's no negative sign in the exponent. This is the case of our function r(x) so we can discard the upper left option.

Another thing to take into account is the offset of the function, that number that I labeled as "c" in the first equation. This offset translates the graph upwards or downwards depending on its sign.

For example, in this image the graphs decrease for negative x values which means their exponents don't have a negative sign but they all tend to different values which means their offsets are different. Blue's offset is 0 since it tends to 0 while gray's offset is 1 because it tends to 1. The same way you can deduce that the orange graph has an offset of -2. In the case of our problem, function r(x) doesn't have an offset which means that in one direction it has to tend to 0. This means we can discard the lower rigth option.

We have already discarded two options, if we discard one more we have the answer.

Now let's take r(x) and evaluate it in x=0:

You don't need a calculator for this because any number raised to 0 lays 1. This means that at x=0 ,i.e. the y-intercept of the graph, the function has y=1.

Lower left graph intercepts the y-axis in 1 while the upper right does it closer to 0 so we can discard this last option.

In summary, we have only one possible option left, the one in the lower left. This is the correct option.

The radius is 1.13 inches and the height of the cylinder is 4.52 inches.

From the information, it's important to use the volume of a cylinder to illustrate the information.

Use the volume of a cylinder.

V = πr²h

V = volume.

r = radius

h = height

where:

V = 18

h = 2(2r) = 4r

Plug in the values into the equation and solve for r.

18 = πr²(4r)

18 = 4πr³

Divide both sides of the equation by 4π.

9 / (2π) = r³

r³ = 1.43

r = 1.13 inches.

Finally, multiply the radius by 4 to get the height. This will be:

= 4 × 1.13

= 4.52 inches.

In conclusion, the height is 4.52 inches.

Given that,

To find the standard form of the equation of the parabola with a focus at (0, 9) and a directrix y = -9.

What is a parabola?

A parabola is a cross-section cut out of the cone and represented by an equation

Focus of the prabola = (h , k + F ) =  (0, 9)

Since the directrix, y =  -9

F = -9

k + F = 9

k = 0

Vertex of the parabola = (h,  k  )

                                    =  (0, 0)

Standard equation of the parabola

( y - k ) = 4a (x - h)²

( y - 0 ) = 4a (x - 0)²

y = 4 * 9 x²

y = 36 x²

Thus, the required expression for the parabola with focus at (0, -9) and a directrix y = 9 is y = 36x².

The price the supermarket can charge per egg that is between the prices of per egg for the two different-sized cartons is $0.245 per egg.

According to the question,

We have the following information:

Cost of 12 eggs in a carton = $3.00

Cost of 18 eggs in another carton = $4.32

Now, to find the charge per egg that is between the prices of per egg for these different-sized cartons, we will first find the charge per egg of both of them.

We know that to find the cost of 1 product we divide the given cost by the number of products.

Cost of 12 eggs in a carton = $3.00

Cost of 1 egg = $ (3.00/12)

Cost of 1 egg = $0.25

Cost of 18 eggs in another carton = $4.32

Cost of 1 egg = $(4.32/18)

Cost of 1 egg = $0.24

Now, we have to find the price of egg between 0.24 and 0.25.

Note the difference between these two charges is 0.01.

We will divide it by 2 to find the exact middle charge:

0.01/2 = 0.005

We can add this in $0.24 or subtract it from$ 0.25.

$0.24 + $0.005 = $0.245

Hence, price the supermarket can charge per egg is $0.245.

ANSWER :

f(x) = (3x-2)(x-3)(x-4)(x-2)^3

EXPLANATION :

A polynomial with a degree of 6 has 6 factors.

f(x) = (x - a)(x - b)(x - c)(x - d)(x - e)(x - f) with 6 roots or x-intercepts.

But the problems states that it has 4 x-intercepts, so we will reduced the number of roots but maintaining the number of factors.

f(x) = (x - a)(x - b)(x - c)(x - d)(x - a)(x - a).

From here, we still have 6 factors but only 4 x-intercepts, the last two factors (x - a) is the same as the first factor.

So we can rewrite this as :

Next is to have a y-intercept of 64, y-intercept is the value of f(x) when x = 0

Substitute 0 to the function.

Now we have f(0) = a^3bcd and f(0) = 64 as the definition from above.

We need to find the factors of 64,

64 = 8 x 4 x 3 x 2/3

And we can rewrite the equation as :

From here, we can observe that,

a^3 = 8 ⇒ a = 2

b = 4

c = 3

d = 2/3

So the function will be :

Explanation in 2/3

Since we only need 4 distinct factors of 64.

8 x 4 x 3 x 2/3

8 x 4 = 32

The product of the 3rd and 4th factor should be 2, in order to get 64.
