Which conic section is represented by 9x^2+4y^2=36

PLEASE ANSWER FAST WILL MARK BRAINLIEST

bixtya [17]

$\sf y=50\left(1.8\right)^{x}$

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

the first term : 50

crosses point : (0, 50), (1, 90)

solve for y,

$\sf y=50\left(1.8\right)^{1}$

$\sf y=90$

<h3>Thus D is correct option.</h3>

How do u graph x+y=-2

sdas [7]

Answer:

The answer is

$y = - x - 2$

Step-by-step explanation:

The problem is

$x + y = - 2$

First we have to bring x to the other side se we subtract x from both sides

$x + y = - 2 \\ - x \: \: \: = - 2 - x$

Then we have to put it in order so the answer is

$y = - x - 2$

URGENT! if ABCD is dilated by a factor of 2, the coordinate of A' would be:

koban [17]

After dilating the quadrilateral ABCD by a factor of 2 and with respect to the origin, the point A(x, y) = (-3, -1) is transformed into the point A'(x, y) = (-9, -3).

<h3>How to determine the coordinates of an image after applying a rigid transformation</h3>

First of all, dilation is a type of <em>rigid</em> transformation. <em>Rigid</em> transformations are transformations applied on <em>geometric</em> loci such that the <em>Euclidean</em> distance at every point of the construction is conserved. Vectorially speaking, the dilation is expressed by the following formula:

A'(x, y) = A(x, y) + k · [A(x, y) - O(x, y)] (1)

Where:

A(x, y) - Original point
O(x, y) - Center of dilation
A'(x, y) - Resulting point
k - Dilation factor

If we know that A(x, y) = (-3, -1), k = 2 and O(x, y) = (0, 0), then the coordinates of A' are:

A'(x, y) = (-3, -1) + 2 · [(-3, -1) - (0, 0)]

A'(x, y) = (-3, -1) + (-6, -2)

A'(x, y) = (-9, -3)

After dilating the quadrilateral ABCD by a factor of 2 and with respect to the origin, the point A(x, y) = (-3, -1) is transformed into the point A'(x, y) = (-9, -3).

2. Ariana has created a paper airplane for her physics class at school where all the students will be testing their planes by se

sergiy2304 [10]

Answer:

2. The airplane will crash into the ground after 5 seconds.

3. The domain of the function is [0,30] and range of the function is $[-\infty,900]$ .

Step-by-step explanation:

2.

Ariana initial attempt is modeled by the function,

$h(x)=x^2-12x+35$

where, h is the height in feet and x is the time in seconds of the paper airplanes path.

If airplane crash into the ground, then $h(x)=0$ ,

$0=x^2-12x+35$

$0=x^2-7x-5x+35$

$0=x(x-7)-5(x-7)$

$0=(x-7)(x-5)$

Equate each factor equal to 0.

$x=5,7$

Therefore the airplane will crash into the ground after 5 seconds.

3.

The height of the rocket in meters is modeled by the function shown below, where t is time in seconds.

$h(t)=-4t^2+120t$

The value of t must be positive because time can not be negative.

Find the zeros of the function.

$0=-4t(t-30)$

$t=0,30$

The leading coefficient is negative, so the it is a downward parabola. Since the zeros of the function are 0 and 30, therefore the function is negative before 0 and after 30.

The height can not be negative, so the domain of the function is

$0\leq t\leq 30$
