Which of these relations is a function? Which number?

Mathematics
1 answer:
PolarNik [594]3 years ago
5 0

Answer:

#1 is the only relation that is a function.

Step-by-step explanation:

The definition of a function is that every x value (within the interval; for continuous functions) has one y value.  This means that one x value CANNOT have two y values and still be a function.  You can use the vertical line test, do this by imagining a vertical line going up and down the graph.  If that line touches two or more points, then that means there are more than 1 y value for at least one of the x values.  That is a quick way to determine if it's a function.  Only #1 passes this test.

I need help in "Matlab' with how to "Create a column vector from 15 to -25 with a step size of 5"
Alekssandra [29.7K]

Answer:

x=[15:-5:-25]'

Step-by-step explanation:

In order to create a vector you need to use this command:

x = [j:i:k]'

This creates a regularly-spaced vector x using i as the increment between elements. j is the initial value and k is the final value. Besides you need to add the character ' at the end in order to convert the arrow vector in a column vector

What is the measure of each angle of a regular 17-gon? If necessary, round to the nearest tenth.
stich3 [128]

For a regular 17-gon, the measure of the internal angles is:

a =  158.8°

<h3>How to measure the internal angles?</h3>

The measure of the sum of the internal angles of a regular figure of N sides is:

(N - 2)*180°

For the case where N = 17, we have:

(17 - 2)*180° = 2,700°

That is the measure of the sum of the internal angles, and we have 17 of them, so the measure of each angle is:

2,700°/17 = 158.8°

Together, a skateboarder and a bicycle cost $199.00. The skateboard costs $51.00 less than the bicycle. How much does each cost?
WITCHER [35]

Answer:

Bike=125 Skateboard= 74

Step-by-step explanation:

x + (x-51)= 199

2x-51=199

2x=250

x=125

125+ (125-51)=199

125+74=199
