find out the value of X, if√x=9

Answers

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

(√ײ)=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

Graph the line passing through the given point and having the given slope (0,3), m=4

Answers

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

Solve for x in the equation 3 x squared minus 18 x + 5 = 47.
x = 3 plus-or-minus StartRoot 23 EndRoot
x = 3 plus-or-minus StartRoot 51 EndRoot
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]

Answer:

33°C

Step-by-step explanation:

The time between 8:20 and 7:50 is 30 minutes. If it drops 1°C per minute you multiply this number by the amount of minutes which would be 30. This becomes 30°C. Then add the 3° it's at now to become 33°C.

Answer: Sin(©)=4/5

Step-by-step explanation: Cos(©)=3/5

Sin(©)=?

By Trigonometric identity,

Sin²(©) + Cos²(©) = 1

Sin²(©) = 1- Cos²(©)

Cos²(©) = (3/5)² = 9/25

Sin²(©) = 1- 9/25 = 16/25

Taking the root of both sides,

√(Sin²(©)) = √(16/25)

Hence, Sin(©) = 4/5

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.

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

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
