Which relation is a function?

Answers

Answer 1

Answer:

Of the provided graphs, the second would be the correct answer.

Functions occur when the input only has one possible output (though the output can be recieved through multiple inputs)

Answer 2

Answer:

The relation shown in the 2nd diagram is a function. The reason for this is that one and only one y-value is associated with each x-value.

Note that this is not true of the first diagram. If x=0, there are two separate y vaues associated: -1 and 2. This clearly states that the first diagram does not represent a function.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Bob was thinking of a number between 5 and 15 that when squared and added to 23 equals the next number's square.

Now,

Let the value of number = x

Hence, We can formulate;

⇒ x² + 23 = (x + 1)²

Solve for x as;

⇒ x² + 23 = x² + 1 + 2x

⇒ x² - x² + 23 - 1 = 2x

⇒ 22 = 2x

⇒ x = 22/2

⇒ x = 11

Thus, The value of number will be;

⇒ 11

To calculate the volume of a cylinder, we have equation like this: V = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. We can measure the diameter (r = d 2 ) and height directly. To calculate the confidence interval of the volume, we should use the propagation of errors. We use the micrometer screw to measure the diameter. The minimum interval on the screw is 0.01mm. What is the confidence interval for δd and δr?

Answers

Answer:

$\delta d =$ +/- 0.01 mm

$\delta r =$ +/- 0.02 mm

Step-by-step explanation:

$\delta d$ . The error of a quantity directly measured is the uncertainty of the tool used for measuring. So error for diameter is 0.01 mm.

$\delta r$ . The error of a quantity obtained multiplying/dividing a measure by a constant is calculated multiplying/dividing the measure uncertainity by the same constant. Radius is calculated as r=2*d, so we calculate $\delta r$ multiplying the diameter uncertainty by 2 ( $\delta r = 2*0.01=0.02$ ).
