and x represents the horizontal distance in yards away from Amanda.
•The rocket will be launched from the ground 1 yard in front of Amanda.
•The rocket will reach a maximum height of 16 yards above the ground when the
rocket is 5 yards in front of Amanda as measured along the ground.
• The rocket would land on the ground 9 yards in front of Amanda.
Which equation represents the rocket's path?

Answer:

The probability that a given household has lost electricity is 10%, or 0.1. So the probability that a given household has not lost electricity is 1 - 0.1 = 0.9.

Since the loss of electricity is independent among the households of the management team, we can find the probability that none of them has lost electricity by multiplying the probability of no loss in any one household (0.9) by itself 6 times, since there are 6 members of the team:

0.9 * 0.9 * 0.9 * 0.9 * 0.9 * 0.9 = 0.54

So the probability that none of the management team members has lost electricity in his or her household is  54%.

Answer:

Line B slope = 9

Step-by-step explanation:

When dealing with perpendicular lines, we can let the slope we know represent m1, while the slope we don't know represents m2.

Thus, to find m2, we use the formula:

[tex]m_{2}=\frac{-1}{m_{1} }[/tex]

If we plug in -1/9 for m1, we have:

[tex]m_{2}=-\frac{1}{(-1/9)} \\m_{2}=9[/tex]

Answer:

a. To determine how many seats should be reserved for premium ticket holders, Frank can use revenue management techniques. One common method is to use the expected revenue per seat, which is calculated by multiplying the number of seats by the expected price per seat and then multiplying that by the probability of that number of seats being sold. Frank can then compare the expected revenues for different numbers of premium seats and choose the number of seats that maximizes the expected revenue.

b. If the number of premium seats is 1,000, then the expected revenue is:

(1,000 x $200 x 0.10) + (75,000 - 1,000) x $40 x 1 = $200,000 + $3,000,000 = $3,200,000

If the number of premium seats is 5,000, then the expected revenue is:

(5,000 x $200 x 0.30) + (75,000 - 5,000) x $40 x 0.7 = $3,000,000 + $2,330,000 = $5,330,000

If the number of premium seats is 10,000, then the expected revenue is:

(10,000 x $200 x 0.24) + (75,000 - 10,000) x $40 x 0.76 = $4,800,000 + $3,768,000 = $8,568,000

and so on for the rest of the numbers.

From the above calculations, we see that the expected revenue is maximized at 10,000 premium seats, which is expected to generate $8,568,000.

c. Using the expected value of the number of premium seats would be calculated by multiplying the number of seats by its probability. The expected value of the number of premium seats is:

1,000 x 0.10 + 5,000 x 0.30 + 10,000 x 0.24 + 15,000 x 0.15 + 20,000 x 0.10 + 25,000 x 0.06 + 30,000 x 0.05 = 10,000.

Comparing this with the number of seats obtained by maximizing the expected revenue (10,000), we see that both approaches yield the same number of premium seats. This means that both approaches would yield the same potential revenue.

The expression in the mathematical form will be (1/4)( 2 - 3x ) / ( 2x ).

So, The line is a horizontal one, and the equation is y = -2 of a line in slope-intercept form if the slope is 0 and the point is (-3, -2).

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. Slope is computed mathematically as "rise over run" (change in y divided by change in x).

Positive slope lines lean to the right, and they become steeper as the slope increases. A line with a negative slope slopes left, and the slope's magnitude determines how steep the line is. Since there is no slope on a horizontal line, it has a slope of zero.

The slope of the line is 0, which means the line is horizontal.

The point-slope form of the equation of a line is: y - y1 = m(x - x1)

With the point (-3, -2) and the slope of 0, we have:

y - (-2) = 0(x - (-3))

y = -2

The slope-intercept form of the equation of a line is: y = mx + b

The y-intercept of the line is -2, so the equation of the line in slope-intercept form is: y = 0x + (-2)

Part (a)

Line p can be named as "line RV" or "line AV" since these points are on line p. The order of the lettering doesn't matter.

==============================================

Part (b)

Pick any three non-collinear points in plane W. In other words, we pick three points in the plane that do not fall on the same line.  

The following points are located in this plane: S, R, Q, T, Z

Here are some possible names:

Something like "Plane SRQ" isn't valid since those three points are on the same line. Infinitely many planes pass through these three points.

The ordering of the letters doesn't matter. For instance, "plane STR" is the same as "plane RTS".

==============================================

Part (c)

As mentioned in part (b) earlier, these points fall on the same straight line. Hence they are considered collinear.

==============================================

Part (d)

Pick any four points that reside in plane W.

You have this list to choose from: S, R, Q, T, Z

Let's say we pick the first four to write S, R, Q, T as the answer

These points are coplanar because they reside in the same plane. The non-coplanar points are A and V since they are outside the plane W.

==============================================

Part (e)

Technically there aren't any line segments shown. Instead the diagram shows lines. But we can focus on a subset of a particular line to form a segment.

For instance, line p has points A and V on it. Therefore we can form segment AV

The symbolic notation for this would be to write [tex]\overline{\text{AV}}[/tex]

==============================================

Part (f)

Reason:

A line is composed of opposite rays. For instance, a vertical line consists of a ray pointing north and a ray pointing south. The two rays are glued together at the endpoints.

For line p, we can glue together ray RA and ray RV to form this line. Unlike the other naming conventions, the order does matter. Something like "ray RV" is not the same as "ray VR". The first letter tells us the endpoint that doesn't go on forever.

Answer:

Rs. 7.50

or a gain of 10%

Step-by-step explanation:

Let x be the price of the stool

10% = 10/100 = 0.10

Loss = 0.1x

Selling price at 10% loss = x - 0.1x = 0.x

We are given this sale price is 67.50

So

0.9x = 67.50

x = 67.50/0.9 = 75

If he sells it at 82.50, the profit would be 82.50 - 75 = 7.5

This would represent a gain of 7.5/75 x 100 percent

= 10%

Answer:

Step-by-step explanation:

67.5 is 90% of 75.

82.50 is 110% of 75.

The equation of the line in slope intercept form is  y = - 1 / 2 x - 8.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Let's find the slope of the line before we can find the equation of the line.

The slope is the change in the dependent variable with respect to the change in the independent variable.

Hence,

m = y₂ - y₁ / x₂ - x₁

Therefore,

(0, -8)(-2, -7)

Hence,

slope = m = -7  + 8 / -2 - 0

m = 1  / -2

m = - 1 / 2

The y-intercept is -8.

Therefore, the equation of the line is y = - 1 / 2 x - 8.

Volume of earth in shape of a sphere is 1 Trillion km^3 i.e. D.

What is a sphere?

A sphere is a three-dimensional object that is round in shape. The sphere is defined in three axes, i.e., x-axis, y-axis and z-axis. This is the main difference between circle and sphere. A sphere does not have any edges or vertices, like other 3D shapes.

The points on the surface of the sphere are equidistant from the center. Hence, the distance between the center and the surface of the sphere are equal at any point. This distance is called the radius of the sphere. Examples of spheres are a ball, a globe, the planets, etc.

Volume of sphere=4/3πr^3. where r=radius.

Surface area=4πr^2.

The intersection of y = x2 and y = 8 —7x is :

y= x2 = 8 — 7x x2 + 7x —8 = 0

We thus have for x > 0 the two curves intersect at x = 1 and y = 12 = 1 .

The limits for integration are --- 0 <x < 1 .

The upper curve is --- y2 = 8 —7x ,

and the lower curve is --- yi = x2 .

The height of the shell is --- h = y2 -yi = 8 —7x — x2 •
