Answer: 5 games

Step-by-step explanation: A .500 record means that the soccer team won half of their games ( that's how I interpret it). Since they are going to play 30 games, they need to win half of 30 or 15 games to have that record. 15-10 = 5. So, they need to win 5 more games to have a .500 record.

Answer:

g = 4

Step-by-step explanation:

if 2 tangent segments are drawn to a circle from the same external point then they are congruent , that is

RJ = RW and MJ = MB and KB = KW

given MR = 6 , then

MJ = 6 - g = MB

given KM = 5 , then

KB = 5 - MB = 5 - (6 - g) = g - 1 = KW

given KR = 7 , then

RW = 7 - KW = 7 - (g - 1) = 8 - g

Then

RJ = RW , that is

g = 8 - g ( add g to both sides )

2g = 8 ( divide both sides by 2 )

g = 4

45 kilograms of meat is required to feed 2 pet dragons each day.

Amara needs 45 kilograms of meat to feed 2 pet dragons each day.

Unitary method is a mathematical way of deriving a single unit then obtaining the required units by multiplying it with the single unit.

According to the given question Amara needs 90 kilograms of meat to feed her 4 pet dragons each day.

Also given that each pet dragon eats the same amount of meat.

∴ 1 pet dragon eat 90/4 kilograms of meat which is

= 22.5 kilograms of meat.

So, Amara need (22.5×2) = 45 kilograms of meat to feet 2 pet dragons.

The measurements that are correct for the given triangle are

sin C = 9/15

B ≈ 53.13°

From the question, we are to determine which of the given trigonometrical ratios for the given triangle are correct

The given triangle is a right angle triangle

Using SOH CAH TOA

sin C = 9/15

∴ The option sin C = 9/15 is correct

Also,

Using SOH CAH CAH

tan B = 12/9

∴ The option tan B = 9/12 is NOT correct

To determine the measure of angle B (m ∠B)

From tan B = 12/9

Then,

tan B = 1.33333

B = tan⁻¹(1.33333)

∴ B ≈ 53.13°

Thus, the option B ≈ 53.13° is correct

Hence, the measurements that are correct for the given triangle are

sin C = 9/15

B ≈ 53.13°

Natalie charges $1490 in rent for each home Per month.

Natalie charges $1490 in rent for each home.

Given that Natalie owns three homes, her monthly rent will be:

= $4470 (3 * 1490) dollars.

The annual income Natalie receives from her three homes is

=($12 * $4470)

= $53680.

Natalie spends $5850 a year on maintenance for each home.

The total amount Natalie spends annually to maintain her three homes is therefore:

=(3 * 5850) dollars, which comes to 17550 dollars.

Then Natalie's annual income would be

= [(53640 - 17550) dollars]

= 36090 dollars.

The total amount Natalie made over the course of seven years was

The formula for moose population is P = 4760 + (number of years x 200).

The moose population in 2003 would be 6760.

When a population increases linearly, it means that it increases by the same amount each year.  

Rate of linear increase: (population in 1999 - population in 1993) / difference in years

(5960 - 4760) / (1999 - 1993)

1200 / 6 = 200

Linear function : initial population + (rate of increase x number of years)

Population in 2003: 4760 + (200 x 10)

4760 + 2000 = 6760

For given question,

We have been given a pair of parametric equations x = 2sin(t) and           y = -3cos(t) on 0 ≤ t ≤ π.

We need to convert given parametric equations to a rectangular equation and sketch the curve.

Given parametric equations can be written as,

x/2 = sin(t) and y/(-3) = cos(t) on 0 ≤ t ≤ π.

We know that the trigonometric identity,

sin²t + cos²t = 1

⇒ (x/2)² + (- y/3)² = 1

⇒ [tex]\frac{x^{2} }{4} +\frac{y^2}{9} =1[/tex]

This represents an ellipse with center (0, 0), major axis 18 units and minor axis 8 units.

The rectangular equation is  [tex]\frac{x^{2} }{4} +\frac{y^2}{9} =1[/tex]

The graph of the rectangular equation [tex]\frac{x^{2} }{4} +\frac{y^2}{9} =1[/tex] is as shown below.

The slope of a line is -2.

The slope of a line can be described as follows:

The slope of a line is a measure of its steepness

Slope = rise / run

slope = y₂ - y₁ / x₂ - x₁

using (0, -4)(-1, -2)

x₁ = 0

x₂ = -1

y₁ = -4

y₂ = -2

Therefore,

slope = -2 - (-4) / -1 - 0

slope = -2 + 4 / -1

Linear equations are equation that has a leading degree of 2. Given the expression that expresses the distance covered by the diver as a function of time as shown;

where;

d is the height of the diver above the water and;

t is the time in seconds.

Given the following

d = 0 (the distance on the ground)

Substitute into the formula below;

-16(2t - 3)(t+1)= 0

Divide through by -16

(2t - 3)(t+1) = 0

Determine the time

Answer:

Step-by-step explanation:

I am assuming you want to factor these functions

G= -x^2 - 2xy - y^2

  =  -(x^2 + 2xy + y^2)

We need 2 terms whose product is y^2 and whose sum is +2xy

- they are  + x and + y

  = - (x + y)(x + y)

  = -(x + y)^2

The other functions are worked out in the same way:

K =  x^2 + 4y^2 + 4xy

  = (x  + 2y)(x + 2y)

  = (x + 2y)^2

H = 4x^2 - 12xy + 9y^2

   = (2x - 3y)^2

L= 25 - 10 + y^2

 = (5 - y)^2

M =  10y^4 + 25x^6 +y^8
