The quadratic equation shown in the graph is:

y = (x + 2)*(x - 1)

Remember that if h and k are the zeros of a quadratic equation of leading coefficient a, we can write it as:

y = a*(x - h)*(x - k)

Here we can see that the zeros are:

x = -2

x = 1

Then we can write it as:

y = a*(x + 2)*(x - 1)

And the y-intercept is -2, then we can write:

-2 = a*(0 + 2)*(0 - 1)

-2 = a*-2

-2/-2 = a

1 = a

The quadratic equation is:

y = (x + 2)*(x - 1)

Ceci should give Fluffles 26 grams of food each day after the 15% reduction.

Given that the original amount of food: 30 grams/day

Now, calculate the 15% reduction:

30 grams/day x 0.15 = 4.5 grams/day

Subtract the reduction from the original amount:

30 grams/day - 4.5 grams/day = 25.5 grams/day

Round the answer to the nearest gram:

25.5 grams/day ≈ 26 grams/day

Thus, she should give Fluffles 26 grams of food each day after the 15% reduction.

Answer:

[tex](x-7)^2+(y+2)^2=49[/tex]

Step-by-step explanation:

A tangent of a circle is a straight line that touches the circle at only one point.

Since the circle is tangent to the horizontal line y = 5, the distance between the center of the circle and the line y = 5 is equal to the radius of the circle.

Given the center of the circle is C(7, -2), the y-coordinate of the center is y = -2. Therefore, the radius of the circle is the difference between y = 5 and y = -2:

[tex]\implies r=5-(-2)=7[/tex]

The equation of a circle is:

[tex]\boxed{(x-h)^2+(y-k)^2=r^2}[/tex]

where (h, k) is the center and r is the radius.

Substitute the given center (7, -2) and found radius, r = 7, into the equation of circle:

[tex](x-7)^2+(y-(-2))^2=7^2[/tex]

Simplify:

[tex](x-7)^2+(y+2)^2=49[/tex]

Therefore, the equation of the circle that has center C(7, -2) and is tangent to the line y = 5 is:

[tex]\boxed{(x-7)^2+(y+2)^2=49}[/tex]

a) Point estimate = 10/19 = 0.526

b) The sample should be randomly selected from the population.

The sample size should be large enough such that both np and n(1-p) are greater than or equal to 10, where n is the sample size and p is the proportion of students who have a job in the population.

The sampling distribution of the sample proportion should be approximately normal.

c) confidence interval = (0.259, 0.793)

d) confidence interval = (0.176, 0.876)

e) n = 365 students

Given data ,

a)

The point estimate for the proportion of GSU students who have a job is simply the proportion of students in the class who have a job, which is:

point estimate = 10/19 = 0.526 (rounded to three decimal places)

b)

To create a confidence interval for the proportion of GSU students who have a job, the following conditions must be met:

The sample should be randomly selected from the population.

The sample size should be large enough such that both np and n(1-p) are greater than or equal to 10, where n is the sample size and p is the proportion of students who have a job in the population.

The sampling distribution of the sample proportion should be approximately normal.

c)

Assuming the conditions for a confidence interval are met, a 95% confidence interval for the proportion of GSU students who have a job can be calculated as follows:

margin of error = z√(p(1-p)/n)

where z is the z-score corresponding to a 95% confidence level (z = 1.96), p is the point estimate of the population proportion (0.526), and n is the sample size (19).

margin of error = 1.96 √(0.5260.474/19) = 0.267 (rounded to three decimal places)

confidence interval = point estimate ± margin of error = 0.526 ± 0.267

confidence interval = (0.259, 0.793)

Therefore, we can say with 95% confidence that the true proportion of GSU students who have a job is between 0.259 and 0.793.

d)

A 99% confidence interval for the proportion of GSU students who have a job can be calculated using the same formula as above, but with a z-score of 2.576 (corresponding to a 99% confidence level):

margin of error = 2.576sqrt(0.5260.474/19) = 0.350 (rounded to three decimal places)

confidence interval = 0.526 ± 0.350

confidence interval = (0.176, 0.876)

Therefore, we can say with 99% confidence that the true proportion of GSU students who have a job is between 0.176 and 0.876.

e)

To determine the sample size needed to be within 3 percentage points of the true proportion with the point estimate of 0.526, we can use the formula:

n = (z² * p * (1-p)) / E²

where z is the z-score corresponding to the desired confidence level (z = 1.96 for a 95% confidence level), p is the point estimate of the population proportion (0.526), and E is the desired margin of error (0.03).

n = (1.96^2 * 0.526 * 0.474) / 0.03^2

n = 364.16

Hence , we would need a sample size of at least 365 students to be within 3 percentage points of the true proportion using the point estimate from the class data.

Using a system of equations, the number of different rolls of yarn that Laura bought is as follows:

A system of equations refers to simultaneous equations.

Simultaneous equations are two or more equations solved concurrently.

The total number of rolls of yarn bought = 25 rolls

The unit cost of multi-colored yarns = $4

The unit cost of solid-colored yarns = $3

The total cost paid for the 25 rolls of yarn = $88

Let the number of rolls of multi-colored yarns = x

Let the number of rolls of solid-colored yarns = y

Equation 1: x + y = 25

Equation 2: 4x + 3x = 88

Multiply Equation 1 by 3:

3x + 3y = 75 ... Equation 3

Subtract Equation 3 from Equation 2:

4x + 3x = 88

-

3x + 3y = 75

x = 13

Substitute x = 13 in either equations 1 or 2:

x + y = 25

13 + y = 25

The exponential function that passes through the points (0,19) and (2,1539) is y = 19(9)ˣ.

We can use the two given points to form a system of two equations in two unknowns (a and b) to find the exponential function in the form y = abˣ that passes through those points.

Using the point (0,19), we get

19 = ab⁰

19 = a

Using the point (2,1539), we get

1539 = ab²

Substituting a = 19 from the first equation, we get

1539 = 19b²

Solving for b, we get

b² = 81

b = 9 or b = -9

Since we are dealing with an exponential function that models a growth, we will choose the positive value for b. Thus, b = 9.

Now that we know a and b, we can write the exponential function in the form y = abˣ

y = 19(9)ˣ

The area of the composite figure is 136 sq. units.

Given that a composite figure we need to find it area,

The figure is composed of a triangle and a rectangle,

So to find its area we will simply calculate the areas of both the polygons and add them,

So, the area of a triangle = 1/2 x base x height

The area of a rectangle = length x width

So,

The required area = 1/2 x (16-8)(13-7) + 7 x 16

= 1/2 x 8 x 6 + 112

= 24 + 112

The range of the cosine function is [-1, 1], there are no real solutions for θ in the given range.

We have,

We can solve the given quadratic equation for cos(θ) using the quadratic formula:

cos(θ) = (-b ± sqrt(b^2 - 4ac)) / 2a

Here, a = 1, b = 7, and c = 4.

Substituting these values, we get:

cos(θ) = (-7 ± √(7² - 4(1)(4))) / 2(1)

cos(θ) = (-7 ± √(41)) / 2

Since 0 ≤ θ < 2π, we need to consider only the solutions that lie in this range.

Using a calculator, we get:

cos(θ) ≈ -3.03 or -0.65

Since the range of the cosine function is [-1, 1], there are no real solutions for θ in the given range.

Answer: x + 10` is **not** a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`.

Step-by-step explanation: To determine if `x + 10` is a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`, we can use the Factor Theorem. The Factor Theorem states that if `f(a) = 0`, then `x - a` is a factor of `f(x)`.

In this case, we want to determine if `x + 10` is a factor of `f(x)`, so we can let `a = -10` and evaluate `f(-10)`:

`f(-10) = 5(-10)^3 + 60(-10)^2 + 109(-10) + 90`

`= -5000 + 6000 - 1090 + 90`

`= -1000`

Since `f(-10) ≠ 0`, we can conclude that `x + 10` is **not** a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`.

Answer:

The equation of the circle is (x + 7)^2 + (y - 13)^2 = 25.

Step-by-step explanation:

The equation of a circle with a center (a,b) and radius r is given by:

(x - a)^2 + (y - b)^2 = r^2

So, for the center (-7, 13) and a radius of 5 units, the equation of the circle is:   (x - (-7))^2 + (y - 13)^2 = 5^2

Simplifying this equation, we get:

(x + 7)^2 + (y - 13)^2 = 25

Therefore, the equation of the circle with center (-7,13) and radius 5 units is (x + 7)^2 + (y - 13)^2 = 25.
