The equation of the line that represents the axis of symmetry of the quadratic function y = 2x² - 16x + 15 is x = 4.

A quadratic equation is a second-degree polynomial equation in a single variable, where the variable is typically denoted by x.

The axis of symmetry of a quadratic function in standard form (y = ax² + bx + c) is a vertical line that passes through the vertex of the parabola. The x-coordinate of the vertex is given by -b/2a, so the equation of the axis of symmetry can be written as x = -b/2a.

In this case, the values of a, b, and c are given as a = 2, b = -16, and c = 15. Substituting these values into the formula for the axis of symmetry, we get:

x = -b/2a

x = -(-16)/(2*2)

x = 4

Therefore, the equation of the line that represents the axis of symmetry of the quadratic function y = 2x² - 16x + 15 is:

Answer:

Step-by-step explanation:

To find the value of n when d = 3, we can use the given inverse proportionality relationship between n and d²:

n ∝ 1/d²

This can also be written as:

n = k / d²

where k is a constant of proportionality.

We are given that n = 5 when d = 12. Plugging in these values into the equation, we get:

5 = k / 12²

To solve for k, we can multiply both sides of the equation by 12²:

5 * 12² = k

k = 720

Now that we have the value of k, we can use it to find the value of n when d = 3:

n = k / d²

n = 720 / 3²

n = 720 / 9

n = 80

So, the value of n when d = 3 is 80.

the required annual interest rate, to the nearest tenth of a percent, is 10.1%

The amount that a lender charges a borrower for the use of money is known as an interest rate, and it is often represented as a percentage of the principle amount (the amount borrowed). It is either the fee for borrowing money or the compensation for lending it.

To find the annual interest rate compounded monthly, we need to use the formula:

[tex]A = P(1 + r/12)^(12*n)[/tex]

where:

A = the final amount

P = the initial principal

r = the annual interest rate (as a decimal)

n = the number of years

In this case, we know that P = 923, A = 1540, n = 2 years, and interest is compounded monthly, which means that there are 12 compounding periods per year.

We can use logarithms to solve for r:

[tex]A = P(1 + r/12)^(12n)[/tex]

[tex]1540 = 923(1 + r/12)^(122)[/tex]

[tex]1540/923 = (1 + r/12)^24[/tex]

[tex]ln(1540/923) = 24 ln(1 + r/12)[/tex]

[tex]ln(1540/923)/24 = ln(1 + r/12)[/tex]

[tex]e^(ln(1540/923)/24) - 1 = r/12[/tex]

[tex]r = 12(e^(ln(1540/923)/24) - 1)[/tex]

Using a calculator, we find that:

The missing number in the set is 19 when the median of a data set is given which is 18.

The median is a measure of central tendency in statistics that represents the middle value of a data set when the values are arranged in order from lowest to highest (or highest to lowest). It is the value that separates the lower 50% of the data from the upper 50% of the data.

To find the missing number, we can first rearrange the given numbers in order from smallest to largest:

12, 13, 17, ___, 21, 25

Since the median of the data set is 18, we know that it is the middle value when the numbers are arranged in order. In this case, there are five numbers, so the median is the third number. Therefore, we have:

12, 13, 17, ___, 21, 25

The missing number must be between 17 and 21 in order for 18 to be the median. We can take the average of these two numbers to find the missing value:

the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.with  the sum of the first n terms of the arithmetic series formula we are able to solve it

what is arithmetic series  ?

An arithmetic series is a series of numbers in which each term is obtained by adding a fixed number to the preceding term (known as the common difference). The sum of the terms in an arithmetic series can be found by multiplying the average of the first and last

In the given question,

We know that the first term of the arithmetic series is given by (2t+1) and the common difference is 3. Therefore, the nth term can be written as:

aₙ = a_1 + (n-1)d

(14r - 5) = (2t + 1) + (n-1)3

14r - 5 = 2t + 1 + 3n - 3

14r - 4 = 2t + 3n

7r - 2 = t + (3/2)n --------(1)

Now, we need to find the values of p, q, and r for the sum of the first n terms of the series, which is given by:

Sₙ = (n/2)[2a_1 + (n-1)d]

Sₙ = (n/2)[2(2t+1) + (n-1)3]

Sₙ = n(3n+4t+2)/2

We can simplify this expression by factoring out a 2 from the numerator:

Sₙ = n(3n+4t+2)/2 = (2n/2)(3n+4t+2)/2

Sₙ = (n/2)(3n+4t+2) = (3/2)n² + 2tn + n

Now, we need to write this expression in the form p(qt-1). To do this, we need to factor out (3/2):

Sₙ = (3/2)(n² + 4/3 tₙ + 2/3 n)

Sₙ = (3/2)[n² + 4/3 tₙ + (2/9)(3n)]

Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n]

Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/9)t² - (4/3)tₙ + (4/3)tₙ]

Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/3)tₙ]

Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)(3t*n)]

Now we can see that p=3/2, q=3t, and r=2/9. Therefore, the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.

The triangle ABC is a right-angled triangle.

What is the right-angled triangle?

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

Here, we have

Given: the points A, B, and C have the coordinates A (5, 2), B (2, -3), and C (-8, 3).

We have to show that the triangle ABC is a right-angled triangle.​

Now, we find the vectors of AB, BC & AC:

AB = (2-5)i+(-3-2)j = -3i-5j

BC = (-8-2)i+(3-(-3))j = -10i+6j

AC = (-8-5)i+(3-2)j = -13i+j

Now if the dot product of two of these vectors results in zero, it means that those vectors (representing the triangle sides) are perpendicular to each other (which means triangle ABC is a right-angled triangle)

AB.BC = (-3)(-10)+(-5)(6) = 30-30 = 0

Hence, the triangle ABC is a right-angled triangle.

Answer:

approximately 21.05 mg.

Step-by-step explanation:

The mass of a radioactive particle at any given time can be calculated using the following formula:

m(t) = m(0) * (1/2)^(t/T)

where:

m(t) = mass of the particle at time t

m(0) = initial mass of the particle

t = time elapsed since the start of the decay process

T = half-life of the particle

Using this formula, we can solve the given problem as follows:

a. The mass at t=0:

Since we are given the initial mass of the particle, we can simply state that:

m(0) = 50 mg

b. Its mass after 40 minutes:

We can use the formula above to calculate the mass of the particle after 40 minutes:

m(40) = m(0) * (1/2)^(40/30)

m(40) = 50 * (1/2)^(4/3)

m(40) = 50 * 0.421

m(40) = 21.05 mg (rounded to two decimal places)

Therefore, the mass of the particle after 40 minutes is approximately 21.05 mg.

The function is non-linear in the cost of buying different numbers of bagels shown.

A non-linear function is a mathematical function that doesn't follow a straight line or a constant rate of change. In other words, it's a function that does not have a constant slope. Non-linear functions are used in various fields such as physics, economics, engineering, and more. An example of a non-linear function is the quadratic function f(x) = x². As x increases, the rate of change of y increases as well, resulting in a curved graph. Non-linear functions can have different degrees, such as cubic or quartic functions, and they can be useful in modeling complex real-world phenomena where the relationship between variables is not linear.

Now

2.40 - 1.25 = 1.15

3.45 -2.40 = 1.05

so 1.15 ≠ 1.05

Answer: 2x + 1

Step-by-step explanation:

The graph of f(x) is a straight line passing through the points (0,1) and (3,4). The slope of this line is (4-1)/(3-0) = 1, and the y-intercept is 1.

The graph of g(x) is a transformation of f(x) obtained by shifting it 1 unit upwards and 1 unit to the left. Therefore, the equation for g(x) is:

g(x) = f(x+1) + 1

Substituting f(x) with its equation, we get:

g(x) = (x+1) + 1

Simplifying:

g(x) = 2x + 2

Finally, we can rewrite the equation of g(x) in the standard form as:

g(x) = 2x + 1

Therefore, the equation for g(x) is 2x+1.

Unfortunately, I cannot see the graph you are referring to. However, if the graph shows a linear function f(x) and its transformation g(x), and g(x) is obtained by shifting f(x) horizontally 1 unit to the left and vertically 1 unit upwards, then the equation for g(x) would be g(x) = f(x + 1) + 1. If f(x) is a linear function of the form f(x) = mx + b, then the equation for g(x) would be g(x) = m(x + 1) + b + 1, which simplifies to g(x) = mx + (m + 1). If you provide more information about the graph, I can help you find the equation for g(x).
