Answer: Median: 44.5 Mode: 45

Step-by-step explanation: Median is the middle number. Since it's an even set, you add the two middle numbers and divide by two. The mode is just the number that appears the most.

1. Solve for x and y: (4 points)<br> Y: __________<br><br> X:__________
Sati [7]

Answer:

Y = 23°

X = 28°

Step-by-step explanation:

[] First, we can tell that (5y - 4) + (3y) = 180 because the parallel lines allow for corresponding angles, and then they are supplementary;

(5y - 4)° + (3y)° = 180°

5y° - 4° + 3y° = 180°

8y° - 4° = 180°

8y° = 184°

y = 23°

[] Next, we can solve for (5y - 4) and use that number as a corresponding angle to solve for (2x + 13);

5y - 4

5(23) - 4

115 - 4 = 111

[] Last, we will solve for x using the same reasoning as how we solved for y;

111° + (2x + 13)° = 180°

111° + 2x° + 13° = 180°

111° + 2x° + 13° = 180°

124° + 2x° = 180°

2x = 56°

x = 28°

Write an equation perpendicular to 5x+6y=18 that passes through the point (10,7)
JulsSmile [24]

Answer:

Step-by-step explanation:

6y = -5x + 18

y = -5/6x + 3

perp slope: 6/5

y - 7 = 6/5(x - 10)

y - 7 = 6/5x - 12

y = 6/5x - 5

A penguin starts on a slide 3 feet above the water. He slides down and glides underwater. The function y=x^2-4x+3 shows his path
Viefleur [7K]

Answer:

( 2 , -1 )

Step-by-step explanation:

Given:-

A penguin starts on a slide 3 feet above the water. He slides down and glides underwater. The function of penguin height above/below the water is given  by:

                                    y = x^2 - 4x + 3

Find:-

-The extreme value (vertex) of the parabolic path

Solution:-

- The vertex ( turning point - minima or maxima ) can be evaluated by taking the first derivative of the given function and setting it equal to zero.

                                  dy/dx = 2x - 4

                                   0 = 2x-4

- Then solve for the critical value of function "x":

                                   x = 4/2 = 2 ft

- The vertex can be evaluated by substituting the critical value of "x" back into the function and evaluate for y:

                                  y = (2)^2 -4*2 + 3

                                  y = 4 - 8 + 3

                                  y = -1 ft

- The vertex of parabolic path lies at the coordinates ( 2 , -1 ). That is 2ft horizontal and 1 ft under water.
