Answer:

[tex]\frac{ (x+3)^2}{9} + \frac{ (y-2)^2}{4} =1[/tex]

-step explanation:

The standard form of the given equation was reduced, representing an ellipse.

The given equation is:

[tex]4x^{2} +9y^{2} +24x-36y+36=0[/tex]

An equation is a statement that equates to two expressions.

We know the above equation represents an ellipse.

Rearranging the given equation

[tex]4x^{2} +24x+9y^{2} -36y+36=0[/tex]

[tex]4(x^2+6x)+9(y^{2} -4y)+36=0[/tex]

[tex]4(x^2+6x+9)+9(y^{2} -4y+4)=36[/tex]

[tex]4(x+3)^2+9(y-2)^2=36[/tex]

[tex]\frac{4(x+3)^2}{36}+\frac{9(y-2)^2}{36} =1[/tex]

[tex]\frac{(x+3)^2}{9}+\frac{(y-2)^2}{4} =1[/tex], which is the standard form of the given equation.

Hence, the standard form of the given equation was reduced.

Answer:

y = 3x + 1

Step-by-step explanation:

x² + 12x + 27 ≥ 0 ?

french reasoning

it is necessary to factorize therefore to seek the roots of the polynomial

Δ = 12² - 4*1*27 = 144 - 108 = 36 = 6²

x' = (-12 + 6)/2 = -3

x'' = (-12 - 6)/2 = -9

so x² + 12x + 27 = (x + 3) (x + 9)

x              - inf              -9              -3            + inf

Given :

Maximum speed limit, s = 80 km/hr

Elena's mom is driving at u = 75 mph.

The police officer explains that 8 kilometres is approximately 5 miles.

To Find :

Was she speeding and by how many km/hr.

Solution :

It is given that 8 km = 5 miles

So,

[tex]1\ miles=\dfrac{8}{5}\ km\\\\1\ miles = 1.6\ km[/tex]

Now, Speed of Elena's mom in km/hr is :

[tex]Speed =\dfrac{75\ miles\times\dfrac{1.6\ km}{1\ miles} }{1 \ hour}\\\\Speed = \dfrac{120\ km}{1 \ hour}\\\\Speed = 120\ km/hour[/tex]

Yes, she is over speeding and by ( 120 - 80 ) = 40 km/hr.

Hence, this is the required solution.

Elena's mom was driving at 120 km per hour, with which she was effectively speeding, exceeding the allowed speed by 40 km per hour.

To determine if Elena's mom was speeding and to determine how many kilometers per hour was she over the speed limit of 80kph the following calculation should be performed:

Therefore, Elena's mom was driving at 120 km per hour, with which she was effectively speeding, exceeding the allowed speed by 40 km per hour.

The function of the brand new smartphone is an exponential function

The function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x

The given parameters are:

Initial value (a) = $1200

Rate (r) = 13.3%

An exponential function that represents a decrement in value is illustrated using:

[tex]f(x) = a(1 - r)^x[/tex]

Substitute known values

[tex]f(x) = 1200(1 - 13.3\%)^x[/tex]

Evaluate the difference

[tex]f(x) = 1200(0.867)^x[/tex]

Hence, the function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x

A soccer coach plans to order more shirts for her team so Each shirt costs $9.85 and She has $77 left in her uniform budget. The possible number of shirts she can buy is  7 shirts.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that A soccer coach plans to order more shirts for her team. Each shirt costs $9.85 and She has $77 left in her uniform budget. WE need to find the possible number of shirts she can buy.

Therefore,

77/9.85 = 7.88888

We an’t have part of a shirt so, she can buy 7 shirts.

Hence,  A soccer coach plans to order more shirts for her team so Each shirt costs $9.85 and She has $77 left in her uniform budget. The possible number of shirts she can buy is  7 shirts.
