The number of horses occupying stalls at the county fairgrounds can be modeled by the following function, where x represents the number of days since the first of June.

h(x)=-3x^2+30+225

Rewrite this function in the form that reveals when there are no horses occupying stalls at the fairgrounds

Answers

Answer 1

Answer:

The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.

Step-by-step explanation:

I assume an x is missing, and the function is h(x) = -3x^2 + 30x + 225

You want to know the number of days in which the function value is zero.

-3x^2 + 30x + 225 = 0

Divide both sides by -3.

x^2 - 10x - 75 = 0

(x - 15)(x + 5) = 0

x - 15 = 0 or x + 5 = 0

x = 15 or x = -5

We discard the negative solution.

Answer: The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.

Answer 2

Answer:

h(x) = -3 (x + 5) (x - 15)

Step-by-step explanation:

h(x) = -3x^2 + 30 + 225

      = -3(x^2 - 10x - 75)

      = -3(x + 5)(x - 15)

      x = -5    x = 15

Find the image of (3, 6) reflected across the y-axis.

Answers

Answer:

(- 3, 6)

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y) → (- x, y), hence

(3, 6) → (- 3, 6)

The image of the point (3, 6) reflected across the y-axis is (-3, 6) since only the x-coordinate changes sign.

Reflection of a point across the y-axis in a Cartesian coordinate system involves changing the sign of the x-coordinate of the point while keeping the y-coordinate the same. For point (3, 6), when it is reflected across the y-axis, the x-coordinate becomes the opposite sign, while the y-coordinate remains unchanged. Therefore, the image of the point (3, 6) after reflection across the y-axis is at (-3, 6). This transformation elucidates the geometric effect of y-axis reflection, showcasing how points are mirrored across the axis while maintaining their vertical position, essential in geometry, graphics, and spatial reasoning for analyzing symmetrical patterns and transformations.

16. Andrew borrowed $695 for a new TV. He will make
10 monthly payments of $75 to repay the loan.
How much will he pay in interest?
$75
$695
$750
$5.50
$55​

Answers

The answer is $55

You multiply 10 by 75 which gives you $750 and subtract the borrowed money by $750 to get $55

Final answer:

Andrew will pay a total of $55 in interest on the $695 loan when he makes 10 monthly payments of $75 each.

Explanation:

The student is asking how much interest Andrew will pay on a $695 loan if he makes 10 monthly payments of $75 each. To find the total interest paid, we need to calculate the total amount Andrew will pay back and then subtract the original loan amount from it.

Total amount paid by Andrew = 10 monthly payments times $75/payment = $750

Original loan amount = $695

Interest paid = Total amount paid - Original loan amount = $750 - $695 = $55

Therefore, Andrew will pay $55 in interest to repay the loan for the new TV.

What is the solution to the equation (picture)?

Answers

Answer:

The solution of the equation is 15

Step-by-step explanation:

* Lets explain how to solve the problem

- The equation is 3(2x + 5) = 3x + 4x

- The solution of the equation is the value of x

Lets find the value of x

- The left hand side is 3(2x + 5) lets simplify it

- Multiply the two terms of the bracket by 3

∵ 3(2x+ 5) = 3 × 2x + 3 × 5

∴ 3(2x + 5) = 6x + 15

- The right hand side is 3x + 4x

∵ They are like terms, then we will add them

∴ 3x + 4x = 7x

- Now equate the left hand side and the right hand side

∴ 6x + 15 = 7x

- Subtract 6x from the two sides

∴ 15 = 7x - 6x

∴ x = 15

∵ x is the solution of the equation

The solution of the equation is 15

What is x? I tried it but I don’t think I did it right.

Answers

Answer:

x = 4

Step-by-step explanation:

When a tangent and a secant are drawn from an external point to a circle.

Then the product of the external part of the secant and the entire secant and the square of the measure of the tangent are equal, hence

x(x + 5) = 6²

x² + 5x = 36 ( subtract 36 from both sides )

x² + 5x - 36 = 0 ← in standard form

(x + 9)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 4 = 0 ⇒ x = 4

However, x > 0 ⇒ x = 4

Bao yu is completing the square to solve the polynomial epuation

What should her first step be ?

Answers

Answer:

The first step would be to add 3 on both sides of the equation.

Step-by-step explanation:

Given a polynomial or a quadratic equation, the first step in completing the square is to take the constant term to the other side of the equation. In the polynomial given the constant term is -3 which implies that we can add 3 on both sides of the equation in order to eliminate this constant term from the left hand side;

x^2 -x -3 +3 = 0 + 3

x^2 - x = 3

Answer:

The first step of Bao yu is to isolate the constant

Step-by-step explanation:

For using completing the square to solve the polynomial equation, the equation should be of the type [tex]a^2 \pm 2ab +b^2[/tex] that can also be written as:[tex](a\pm b)^2[/tex]

so, for the given equation: [tex]x^2 -x -3 =0[/tex]

The first step should be to isolate the constant:

[tex]x^2 -x = 3[/tex]

Then we have to make the middle term according to 2ab where a = 1x and b= (1/2) i.e, -2(1x)(1/2) = 1x

so,by adding (1/2)^2 on both sides of equation, we can complete the formula:

[tex]x^2 -x = 3[/tex]

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

Solving we get,

[tex](x- (\frac{1}{2}))^2 = 13/4[/tex]

So, the first step is to isolate the constant.

Answer:

5/9

Step-by-step explanation:

To have an even number (let's call it E) OR a number greater than 9 (let's call it N), you can have EITHER of them.

So, to calculate the probability, you need to find the probability of having E and then the probability of having N... then ADD them together.

To calculate the probability, just look on the image.

Probability of having an even number: 18 (red circles)

Probability of having a number greater than 9 (that is NOT already counted in the even scenario): 2 (within the blue zone, but not red)

We don't count a same possibility (like 6,4) twice, only once.

Total: 18 + 2 = 20

Out of 36 possibilities

So, probability is 20/36, or 10/18 or 5/9.

In a fish tank 75% of the fish are goldfish. How many fish are in the tank if there are 24 goldfish pls answer!!!!!!

Answers

I believe it’s 8 because 24 divided 75% is 32.

To find the total number of fish in a tank where 75% are goldfish and there are 24 goldfish, solve the equation 0.75 × Total Number of Fish = 24, resulting in 32 fish in total.

The question asks about calculating the total number of fish in a tank knowing that 75% of them are goldfish, and there are 24 goldfish. To find the total number of fish in the tank, we set up a proportion based on the given information that 75% (or 0.75 when converted to a decimal) of the total number of fish equals 24 goldfish.

Mathematical equation: 0.75 × Total Number of Fish = 24.

To solve for the Total Number of Fish, we divide both sides of the equation by 0.75:

Total Number of Fish = 24 ÷ 0.75

Total Number of Fish = 32

Therefore, there are 32 fish in the tank in total.

Somewhat Disagree: 16°

Neither Agree nor Disagree: 100°

Somewhat Agree: 350/900 = 140°

Strongly Agree: 200/900 = 80°

Step-by-step explanation:

To find the degrees on a pie chart we need to find the proportion of each category over the total.

The total is: 60 + 40 + 250 + 350 + 200 = 900

The proportions of each category is going to be:

Strongly Disagree: 60/900 = 1/15.

Somewhat Disagree: 40/900 = 2/45.

Neither Agree nor Disagree: 250/900 = 5/18.

Somewhat Agree: 350/900 = 7/18.

Strongly Agree: 200/900 = 8/9.

We find the degrees by multiplying the proportions to 360 degrees as follows:

Strongly Disagree: 24°

Somewhat Disagree: 16°

Neither Agree nor Disagree: 100°

Somewhat Agree: 350/900 = 140°

Strongly Agree: 200/900 = 80°

The total should be 360°. Let's prove it:

24 + 16 + 100 + 140 + 80 = 360°.'

The area of a rectangle is 80 ft2. If the rectangle is 8 feet long, what is its width?

7 feet

9 feet
10 feet

Answers

Answer:

10 feet

Step-by-step explanation:

Area of rectangle

A = L * W

W = A/L

W = 80 / 8

W = 10

Answer

10 feet

The Area of the rectangle is the product of length and width. The width of the rectangle is 10 ft.

How to find the area and the perimeter of a rectangle?

For a rectangle with length and width L and W units, we get:

Area of the rectangle = (L × W) unit^2

Perimeter of the rectangle = 2(L + W) units

Given the area of the rectangle is 80 ft², while the length of the rectangle is 8 feet. Therefore, the width of the rectangle will be,

Area of the rectangle = Length × width

80 ft² = 8 ft × width

width = 10 ft

Hence, the width of the rectangle is 10 ft.
