The y-intercept of the graph of f(x) = x^2 - 3x + 5 is (0, 5).

The equation of the axis of symmetry is x = (3/2).

The x-coordinate of the vertex is (3/2), and the y-coordinate of the vertex is (5 - (9/4)) = (-1/4).

So the vertex of the graph of f(x) = x^2 - 3x + 5 is (-1/4, (3/2)).

To graph the function, you can start by plotting the vertex, then use the axis of symmetry to reflect the parabola across the line x = (3/2). The y-intercept is the highest point of the parabola if it opens upwards, and the lowest if opens downwards. This can be used to confirm the direction of the parabola.

A quadratic function's U-shaped curve is seen on a parabola graph. A right circular cone and a plane surface intersect to generate one of the conic sections known as a parabola in mathematics. It has a U-shaped symmetry in the plane. The conventional form of a parabola is a graph whose equation takes the form f(x) = ax2+bx+c. A parabola's vertex is its most extreme point, and the vertical line that runs through it forms its axis of symmetry.

Answer: To find Janice's running speed, we need to determine how many miles she runs per hour.

We know that the track is 1/4 mile long and Janice can complete each lap in 1/10 of an hour. To find the total number of miles Janice runs in an hour, we can multiply the length of the track by the number of laps she completes in an hour.

Length of the track * number of laps = total miles

1/4 mile * (1/10 hour)^-1 = total miles

On the second equation, we are using the inverse of the time, to get the number of laps completed in an hour

The speed is distance over time, so we need to express the distance in miles and the time in hours.

So Janice's running speed is 4 miles/hour.

The image of (12,-12) after a dilation by a scale factor of 1/3 centered at the origin is (4, -4).

What is dilation at origin?

On the coordinate plane, figures can be magnified. The centre of dilation is frequently the origin. The coordinates of the points in the preimage can be multiplied by the scale factor to get the points in the image if you are distorting a figure that is centered at the origin.

We have to find the image of (12,-12) after a dilation by a scale factor of 1/3 centered at the origin.

To find the image after dilation multiply both coordinates (12, -12) by 1/3 which is the same as dividing by 3.

⇒  (12, -12)*1/3 = (4, -4)

Hence, the image of (12,-12) after a dilation by a scale factor of 1/3 centered at the origin is (4, -4).

So on solving the provided question, we can say that inequality equation will be as follows r - 8 <= 7 r<=15 or r >= -15

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

The partial fraction expansion for the rational function

S/ (s - 7) (s^2 - 49) = -25-56/ (5+3) (s^2+ 16) - 2s - 56 / (s +3) (s^2 + 16)

can be found by decomposing it into the sum of simpler fractions.

One way to do this is to use the method of long division and then match the coefficients of the resulting polynomials. The process is as follows:

Divide S by (s - 7) to get a quotient of S1 and a remainder of R1.

Divide R1 by (s^2 - 49) to get a quotient of S2 and a remainder of R2.

Write the expansion as S1 + S2 + R2/(s - 7)(s^2 - 49)

Alternatively, we can use the method of partial fraction decomposition by inspection.

To do this, you will write the rational function as the sum of simpler fractions with the same denominator.

S/ (s - 7) (s^2 - 49) = A/(s-7) + B/ (s^2 - 49) + (C*s + D)/(s^2 - 49)

where A, B, C, and D are unknowns that you will find by matching coefficients.

S = (A(s^2-49) + B(s-7) + C*s + D) / (s-7) (s^2-49)

You can use this equation to solve for A, B, C, and D by matching coefficients.

-25-56/ (5+3) (s^2+ 16) - 2s - 56 / (s +3) (s^2 + 16) = A/(s-7) + B/(s^2 - 49) + (C*s + D)/ (s^2 - 49)
