Answer:

y = (x - 2)^2 + 1

Step-by-step explanation:

The general equation of a parabola in vertex form is y-k = (x-h)^2.  Here, we can see immediately from the graph that the vertex is at (2, 1).  Thus, the equation of this particular parabola takes the form y - 1 = a(x - 2)^2.  We must still determine the value of a.  Note that the graph goes through (0, 5).  Thus, 5 - 1 = a(0 - 2)^2, or

4 = 4a.  Thus, a = 1, and the equation of this parabola is y - 1 = (x - 2)^2, or, after simplification, y = (x - 2)^2 + 1.

Hi,

Here is the solution.

3 years = 36 months

Leased amount for 3 years = $3000 + 36*350

= $3000 + $12600

Leased amount for 3 years = $15600

Residual value = $12000

Assume you didn't buy the car, you took it for lease, so your expense = $15600.

Now Assume you bought the car for $21,000.

After using 3 years, you can sell it for $12000.

Your expense = $21,000 - $12,000 = $9000.

Conclusion:

It is less expensive to buy the car.

The cost for buying the car and selling it after 3 years = $9000.

Hope you will understand the steps. Thank you :)

Answer:

Step-by-step explanation:

First, you will add 2x for both sides.

y - 2x = 3

  +2x       +2x

Then, you will get y = 2x + 3

So the slope will be 2

Same side.  Locate -3.9 on the number line.  Then -0.99 is to the right of -3.9, with both numbers being on the same side (that is, on the left side) of zero.

Same side, think of it as a number line. there is a left side for negitives, and a right for positives. Every negitive number is on the same side, while the positives have their own side too. Only if it was a positive with a negitive it would be on opposite sides.

Answer:

It is Milk

Step-by-step explanation:

The liquid in the bottle has mass given in grams and the mass of that substance is 117 grams.

The volume of the substance is 15 cubic centimeters.

Now, using the formula of density we can estimate which substance could it be.

[tex]d=\frac{m}{v}[/tex], where 'd', is the density, 'm' is the mass, and 'v' is the volume of the substance.

Plugging the value of mass and volume we get:

[tex]d=\frac{117}{15} =7.8g/cm^3[/tex]

So the density of the substance is 7.8 grams per cubic centimeter.

It cannot be water since the density of water is 1 grams per cubic centimeter.

It cannot be gasoline because its density is 0.77 grams per cubic centimeter.

It cannot be mercury because the density of mercury is 13.56 grams per cubic centimeter.

Since, the density in this case matches the density of thick milk and hence,therefore, the liquid in the bottle is milk.

Let us calculate the area of the walk.

Since the width of the walk is 3 feet, and the walk will be placed all the 4 sides,

Length of the plot including walk = 20 + (2 × 3) = 20 + 6 = 26 feet.

Breadth of the plot including walk = 30 + (2 × 3) = 36 feet.

Area of the plot including walk = 26 × 36 square feet.

Area of the plot = 20 × 30 square feet.

Area of the walk = (26 × 36) - (20 × 30)

= 936 - 600

= 336 square feet.

= [tex]\frac{336}{3(3)}[/tex] square yards

= 37.3 square yards

Cost of the walk per square yard = $12.25.

Therefore, total cost of the walk = 12.25 × 37.3 = $456.92.

Eduardo's pre-tax income is calculated as: $69,216.

To find Eduardo's pre-tax income, we need to first calculate how much he contributes to his 401(k) plan.

We know that he contributes 16% of his $82,400 annual salary, so:

16% of $82,400 = 0.16 * $82,400

= $13,184

This means that Eduardo contributes $13,184 to his 401(k) plan each year. To find his pre-tax income, we need to subtract this amount from his annual salary:

$82,400 - $13,184 = $69,216

Therefore, Eduardo's pre-tax income is $69,216.

Final answer:

Eduardo's pre-tax income is his annual salary of $82,400. His 401(k) contribution is 16% of this amount, but it does not reduce his pre-tax income.

Explanation:

Eduardo’s pre-tax income is the total amount he earns before any deductions such as his 401(k) contributions. Since he contributes 16% of his $82,400 annual salary to his 401(k) plan, we calculate the contribution amount and then affirm that it is part of his pre-tax income, which is the full $82,400. To find the contribution amount, we use the formula:

Contribution = (Percentage / 100) × Salary

Contribution = (16 / 100) × $82,400

Contribution = 0.16 × $82,400

Contribution = $13,184

Hence, Eduardo’s pre-tax income remains $82,400 for the year, not the amount after the contribution is subtracted.

[tex]C(7;-8)[/tex]

Answer:

The coordinates of endpoint C are (7,-8).

Step-by-step explanation:

Given information: Midpoint of BC is (5, -2) and B(3,4).

We need to find the coordinates of C.

Let the coordinate of C are (x,y).

If end points of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the midpoint of that segment is

[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Midpoint of BC is

[tex]Midpoint=(\frac{3+x}{2},\frac{4+y}{2})[/tex]

Midpoint of BC is (5,-2).

[tex](5,-2)=(\frac{3+x}{2},\frac{4+y}{2})[/tex]

On comparing both sides.

[tex]5=\frac{3+x}{2}[/tex]

[tex]10=3+x[/tex]

[tex]10-3=x[/tex]

[tex]7=x[/tex]

The value of x is 7.

[tex]-2=\frac{4+y}{2}[/tex]

[tex]-4=4+y[/tex]

[tex]-4-4=y[/tex]

[tex]-8=y[/tex]

The value of y is -8.

Therefore the coordinates of endpoint C are (7,-8).

Answer:

Doing the assignment got all right answers x + y = –1, x + 4y = 0, 8x – 3y = 20

Step-by-step explanation:

The linear equations written in the standard form are x + y = -1, x + 4y = 0 and 8x – 3y = 20.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Standard form of a linear equation is, Ax + By = C, where A, B and C are integers.

We have to select all the linear equations which are of the form as given above.

x + y = -1 is in standard form, where A = 1, B = 1 and C = -1

x + 4y = 0 is in standard form, where A = 1, B = 4 and C = 0

8x – 3y = 20 is in standard form, where A = 8, B = -3 and C = 20

Other equations  –3x = y, y = 5x – 2 and x = 3 – 0.1y are not in the standard form.

Hence the equations in the standard form are x + y = -1, x + 4y = 0 and 8x – 3y = 20.

Answer: B) 90

Since c is perpendicular to b (given) and line 'a' is parallel to line c (also given), this means line 'a' is perpendicular to line b.

Put another way, angles 5, 6, 7, 8 are all 90 degrees (since c is perpendicular to b). If a || c, then angles 2 and 6 are corresponding angles that are congruent.

So this is why angle 2 is also 90 degrees.

Final answer:

The annual population growth rate for the raccoons is calculated using the formula which involves subtracting the initial population from the final population, dividing by the initial population, and then multiplying by 100%. The growth rate is approximately 150.26%.

Explanation:

To calculate the annual population growth rate for the raccoons, we use the following formula:

Growth Rate = (Final Population - Initial Population) ÷ Initial Population × 100%

Initial Population = 189 raccoons

Final Population = 473 raccoons

Plugging in the values we get:

Growth Rate = (473 - 189) ÷ 189 × 100%

Growth Rate = 284 ÷ 189 × 100%

Growth Rate ≈ 150.26%

Therefore, the annual population growth rate for the raccoons is approximately 150.26%.

This is a rotation of 180° so (x, y) → (-x, -y)

The signs of the coordinates changed.

Alternate exterior angles

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

Step-by-step explanation:

The parallel lines are like the metal parts of a train track, so I'll just refer to these lines as "train tracks" from now on. Note how x and y are on the outside or exterior of the train tracks. At the same time, they are on opposite or alternate sides of the transversal line.

Since x and y are on the alternate sides of the tranversal line, and they are on the exterior of the train tracks, we have alternate exterior angles

Answer:

y= -23.8

Step-by-step explanation:

I don't know if this is the right answer but you can try

When x is -6, y is approximately -23.8.

The given equation is y = 2 + 4.3x, and you want to find the value of y when x = -6.

Substitute x = -6 into the equation:

y = 2 + 4.3 * (-6)

Now, calculate the value:

y = 2 - 25.8

Simplify:

y = -23.8

When x = -6, the value of y is -23.8.

This means that if you plug in x = -6 into the equation, you will get y = -23.8 as the corresponding y-coordinate on the graph.

This represents a point on the line described by the equation y = 2 + 4.3x when x is -6, y is -23.8.

Let's say the cost to feed each horse is $5.00.

The expression would be written as:

(5.00)h or simplified as 5h

This is because you are multiplying the cost for feeding each horse by the amount of horses, represented as h.

If you are feeding 6 horses you would substitute the h for 6 giving you the expression:

which equals $30 total.
