Identify a function rule for the following ordered pairs (0, -1), (2, 3), (3, 8), (4, 15)

A) y=x^2

B) y=x-1

C) y=x²-1

D) y=2x-1

Answers

Answer 1

Answer:

C

Step-by-step explanation:

Looking at the first point we know that it can't be A

Then we can easily see that the rate of change is not level (which means it isn't linear)

this leaves option C

Another way to solve this is just by plugging in points

for example for C

(4,15)

15=4^2-1

15=15

Miguel walked Ask Your Teacher mile to the library and then Ask Your Teacher mile to the post office. How can he write Ask Your Teacher and Ask Your Teacher as a pair of fractions with a common denominator?

Answers

Answer:

[tex](\frac{5}{10},\frac{6}{10})[/tex]

Step-by-step explanation:

Given

[tex]Library \to \frac{1}{2}[/tex]

[tex]Post\ Office \to \frac{3}{5}[/tex]

See comment for complete question

Required

Write as a common denominator

Take the denominator of both fractions

[tex]2 \to[/tex]

[tex]5 \to[/tex]

Calculate the LCM

[tex]2 \to 1 * 2[/tex]

[tex]5 \to 1 * 5[/tex]

[tex]LCM = 1 * 2 * 5[/tex]

[tex]LCM = 10[/tex]

Multiply the numerator and the denominator of both fractions by 10

Simplify each to ensure a denominator of 10

[tex]\frac{1}{2} \to \frac{1}{2} * \frac{10}{10} \to \frac{1}{1} * \frac{5}{10} \to \frac{5}{10}[/tex]

[tex]\frac{3}{5} \to \frac{3}{5} * \frac{10}{10} \to \frac{3}{1} * \frac{2}{10} \to \frac{6}{10}[/tex]

Hence, the pair is:

measure of angle ABC is 6 degree.

Step-by-step explanation:

After you found x, you'll plug it in the equation of the angle it's asking for.

Measure of angle ABD, and you know measure of angle ABC = 4x-1.

4(1)-1 = 4-1 = 3

Measure of angle CBD = 2x+1.

2(1) +1 = 3

Measure of angle ABC is ABD + CBD

3 + 3 = 6

Answer:

Step-by-step explanation:

We know that is 4x - 1 + 2x + 1

So it equals

6x

or 6 ( 1) = 6°

Answer:

C

Step-by-step explanation:

Sine equals opposite over hypotenuse, which would be y/19. To find y multiply by 19 to get y=19sin33°

Correct answer: 19cos33°

The values given are 19 (hypotenuse), y (adjacent side), and the angle (33°)

The formula for cosine is adjacent side divided by the hypotenuse

After plugging in the values given into the formula cosx=ad/h, we have:

Cos33°=y/19 Here, we need to isolate the Y

And, the final result is
19Cos33°= Y

So, the correct answer is the letter D

Complete question

Mr porter had eight parties at her house last year the number of guests at each party is shown below 15,19,9,27,21,21,10,14. What is the median numbers of those parties

The median value is the value at the middle after rearrangement

On rearranging in ascending order

9, 10, 14, (15, 19), 21, 21, 27

Since there are two values in the middle, we will take the average of the numbers

Median = 15+19/2

Median = 34/2

Median = 17

Hence the median value is 17
