In Algebra, we learn about functions of various types. These functions are often seen in a progression from least complicated (linear) to most complicated (piecewise with nonlinear parts). And then there are other types of functions in-between: exponential, quadratic, polynomial, radical, and logarithmic. But with all their differences and unique properties, these share a common trait of being functions that we can graph in a coordinate plane.

What are some other things you can observe to have that same quality of functions: unique, but sharing a common trait or purpose?

Answers

Somethings I can observe that have the same quality is that all functions only have one outcome for a given input. A vertical line will never meet the graph more than once. No X values are used more than once. A function will have either no horizontal asymptote or just one asymptote. These are some common traits that all functions have.

We can see that all functions have the one outcome for one value of x if we can see all the functions carefully.

What is a function?

A function is a relation in which each value of x corresponds to some value of y.

How to determine the features of a function?

When we see some functions, they have the same quality of giving one result for one  input. The quality of the graph of all functions is that the vertical line cannot meet the axis twice.

Step-by-step explanation:

minimum or maximum value of f(x)=−0.5x2+2x−5.

Answers

In the equation assign each number a letter:

A = -0.5, b = 2 and c = -5

Maximum = -b/2a = -2/2(-0.5) = 2

Minimum = replace x in the equation with the maximum and solve for y:

-0.5(2)^2 +2(2) -5 = -3

Maximum and minimum = (2,-3)

At a certain intersection, the traffic light is red for 15 seconds, yellow for 5 seconds and green for 30 seconds. Find the probability that, of the next eight cars that arrive randomly at the light, exactly three will be stopped by a red light.

Answers

Answer: 0.254

Step-by-step explanation:

Given that:

Number of cars = number of trials (n) = 8

Number that will be stopped by a red light = Numbe rof successes (r) = 3

Probability of success :

Red light = 15 seconds ; yellow = 5 seconds ; green = 30 seconds

P(red) = p(success) = p = 15 / (15 + 5 + 30) = 15/50 = 3 /10 = 0.3

1 - p = 1 - 3/10 = 7/10 = 0.7

Using the binomial probability relation:

p(exactly 3):

P(8, 3) = 8C3 * p^3 * (1-p)^(8-3)

P(8, 3) = 8C3 * p^3 * (1-p)^5

P(8, 3) = 56 * 0.3^3 * 0.7^5

= 0.25412

= 0.254

X = 63, y = 70, z = 41
Od

Answers

Answer:

Option (A)

Step-by-step explanation:

From the given triangle in the picture,

∠y and the angle measuring 81° is a pair of supplementary angles (linear pair angles).

m∠y + 81° = 180°

m∠y  = 180° - 81°

        = 99°

By the property of a triangle,

x° + y° + 47° = 180°

x° + y° = 180° - 47°

x° + y° = 133°

For y = 99°

x° + 99° = 133°

x° = 133° - 99°

   = 34°

Similarly, z° + 58° + 81° = 180°

z° + 139° = 180°

z° = 180° - 139°

z° = 41°

Therefore, Option (A) will be the correct option.

Applying the definition of the straight line angle and sum of triangle, the values of the variables in the figure are:

x = 34, y = 99, z = 41

Recall:

Angles on straight line = 180°Sum of triangle = 180°

Thus:

y° + 81° = 180° (angles on a straight line)

Subtract 81 from each side

y° = 180° - 81°

y° = 99°

x° +  y° + 47° = 180° (sum of triangle)

Substitute

x° + 99° + 47° = 180°

x° + 146° = 180°

Subtract 146° from each side

x° = 180° - 146°

x° = 34°

z° + 81° + 58° = 180° (sum of triangle)

z° + 139° = 180°

Subtract 139° from each side

z° = 180° - 139°

z° = 41°

at springtown café, 5/9 of the customers left a large tip. In contrast, 3/10 of the customers at Allenville bistro left a large til. Which restaurant had a greater fraction of customers who left a large tip? please help

Answers

Answer:

Springtown Cafe

Step-by-step explanation:

If you want to be sure, find a common denominator. 9 and 10 are the denominators of each fraction. Find the multiples of each (9's multiples would be 9, 18, 27, etc.) and find a common multiple between the two. In this case, it would be 90. Multiply the denominator to get the common denominator. 9 x 10 = 90, 10 x 9 = 90. Remember to multiply both the top and bottom.

5/9 = 50/90

3/10 = 27/90

Now, we can clearly see that 5/9 is larger than 3/10.

So, Springtown cafe has a greater fraction of customers who left good tips.
