Point A has coordinates (-5, 3). If point (1,6) is
of the way from A to B what are the coordinates of point B?

Answers

Answer:

[tex](3, 7)[/tex]

Step-by-step explanation:

(4/3)P -(4/3)A + A = B . . . . . . add A

(4P -A)/3 = B . . . . . . . . . . . . . simplify

Then the coordinates of point B are ...

B = (4(1, 6) -(-5, 3))/3 = (9, 21)/3

B = (3, 7)

find out the value of X, if√x=9

Answers

To find this answer, take both sides of the equality and square them:

(√×²)=9²

This gives you:

×=81

If √x=9 then the value of x is 81.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is √x=9

Square root of x is equal to nine.

We need to find the value of x.

√x=9

Apply square on both sides

(√x)²=9²

The root and square will be cancelled on the left side

x=9²

Nine to the power of 2 is eighty one

x=81

Hence, the value of x is 81 when √x=9

x = 3 plus-or-minus StartRoot 41 EndRoot
x = 3 plus-or-minus StartRoot 5 EndRoot

Answers

Answer:

first option

Step-by-step explanation:

3x² - 18x + 5 = 47 ( subtract 5 from both sides )

3x² - 18x = 42 ( divide through by 3 )

x² - 6x = 14

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = 14 + 9

(x - 3)² = 23 ( take square root of both sides )

x - 3 = ± [tex]\sqrt{23}[/tex] ( add 3 to both sides )

x = 3 ± [tex]\sqrt{23}[/tex]

The director of student life at a university wants to estimate the proportion of undergraduate students who regularly park a car on campus. Describe how to select a stratified random sample of approximately 100 students. Explain your choice of strata and why stratified random sampling might be preferred in this context.

Answers

Random sampling involves selecting a sample where each element of the sample have an equal probability of selection.

From the question, we understand that the director wants to make use of a stratified random sampling technique.

The stratified random sampling technique involves selecting the sample (i.e. 100 students), by dividing the whole undergraduate students into groups (i.e. strata), and then select a proportion from each group.

A possible way to achieve this, is as follows:

Divide the undergraduate students in faculties (assume the university has 10 faculties)Then select 10 students from each of the 10 faculties.

With the above highlights, the director would be able to make the selection.

Hint :-

To find out the equation of the line we can use the point slope form of the line which is [tex] y - y_1 = m(x-x_1) [/tex]

Solution :-

The given point to us is , [tex](0,3)[/tex] and the slope of the line is 4 . On using the point slope form , we have ,

[tex]\implies y - y_1= m(x-x_1) \\\\\implies y-3 = 4(x-0) \\\\\implies y -3 = 4x \\\\\implies \boxed{ 4x - y + 3 =0}[/tex]

Hence the equation is 4x - y + 3 = 0

Mr. Cash bought d dollars worth of stock. During the first year, the value of the stock tripled. The next year, the value of the stock decreased by $1200. (a) Write an expression in terms of d to represent the value of the stock after two years. (b) If an initial investment is $1,000, determine its value at the end of 2 years.

Answers

Answer:

1. 3D-1200 = value after two years.

2. $1800 = value after two years

Step-by-step explanation:

When the value of D triples, 3 times D = 3D. value of the stock after two years decreased, would be the -1200.

When you get the value of 1,000 you can plug it in to get 3 (1000) - 1200 = Stock price after two years

A plane flies at a speed 580 km/hr at a constant height of 16 km. How rapidly is the angle of elevation to the plane changing when the plane is directly above a point 125 km away from the observer?

Answers

Answer:

-0.584 rad/hr, rounded to the nearest 1000th

Step-by-step explanation:

Let D = D(t) = the horizontal distance from the observer to the plane at time t in units of km.

Let E = E(t) = the angle of elevation at time t in units of Radians.

Then, by geometry,

tan(E) = 16 / D, and furthermore, we have that

tan(E) = 16 * D^(-1)

d/dt (tan(E)) = d/dt ( 16 * D^(-1))

sec^2 (E) * dE/dt = 16(-1)(D^(-2)) * dD/dt

( sqrt(D^2 + 16^2) / D )^2 * dE/dt = -16 (D^(-2)) * dD/dt

(D^2 + 16^2)/D^2 * dE/dt = -16 (D^(-2)) * dD/dt

dE/dt = -16 (D^(-2)) * dD/dt * D^2 / (D^2 + 16^2)

dE/dt = -16 (dD/dt) / (D^2 + 16^2)

dE/dt = -16 (580 km/hr) / (125^2 + 16^2), at time t such that D(t) = 125 km,

dE/dt = (-9280 / 15881) rad/hr

dE/dt = -0.584 rad/hr, rounded to the nearest 1000th

While hes on the phone with the dispatcher, he seems suspicious, leaving out certain details and refusing to give any information about himself or how to contact him. However, the 911 dispatcher can track his phones location automatically, and the police arrived at his door without a warrant. They just plan to talk to him, and try to persuade him to give more information on his own.Joe has already locked his front door and fled the scene, specifically to avoid speaking with the officers. However, the artificial intelligence that controls Joes smart house knows Joe recently called 911, and it is programmed to assist emergency responders in case the residents of the house need to be rescued.
