Determine whether each table represents a linear, quadratic, exponential function.

Nesterboy [21]

Answer:

A: Exponential

B: Quadratic

C: Linear

Step-by-step explanation:

Let analyse each table

Table A

X Y ΔY/ΔX

1 5 xxxxxx

2 11 11 - 5 = 6

3 29 29 - 11 = 18

4 83 83 - 29 = 54

.....................

We can see that, [ ΔY/ΔX ] increases at the fastest rate out of all functions, so it must be exponential function

Table B

X Y ΔY/ΔX Δ^2Y/ΔX^2

0 5 xxxxxx xxx

1 7 7 - 5 = 2 xxx

2 13 13 - 7 = 6 6-2 = 4

3 23 23 - 13 = 10 10-6 = 4

..............................

It is a quadratic because Δ^2Y/ΔX^2 = 4 and are constant for all values

Table C

X Y ΔY/ΔX

3 20 xxxxxx

6 18 2 / 3

9 16 2 / 3

15 12 2 / 3

..............

It is a linear because ΔY/ΔX = 2/3 are constant for all values

Please help i'll fail if i don't pass this will give brainliest!

Veronika [31]

Answer: $b^2+h^2=x^2$

Step-by-step explanation: The line labeled $x$ here is called the hypotenuse. There are a few ways to calculate the hypotenuse, but the most common way is by using this equation: $b^2+h^2=x^2$ .

I hope this helped! ;) Good luck on your test or quiz or whatever you have to do in order to pass!

In 1990, it cost $800,000 for a 30-second commercial during the Super Bowl. In 2020, the cost for a 30-second commercial was $5,

lesya [120]

Answer:

690%

Step-by-step explanation:

To find the percent increase, take the new amount and subtract the original amount

5600000-80000=5520000

Divide it by the original amount

5520000/800000

6.9

Multiply this by 100% to change from decimal form to percent form

6.9*100%

690%

Which expressions are equivalent??

Brilliant_brown [7]

Given:

The given expression is $2\left(\frac{3}{4} x+7\right)-3\left(\frac{1}{2} x-5\right)$

We need to determine the equivalent expression.

Option A: -1

Solving the expression, we get;

$\frac{3}{2} x+14-\frac{3}{2} x+15$

Simplifying, we get;

$14+15=29$

Thus, the expression $2\left(\frac{3}{4} x+7\right)-3\left(\frac{1}{2} x-5\right)$ is not equivalent to -1.

Hence, Option A is not the correct answer.

Option B: 29

Solving the expression, we get;

$\frac{3}{2} x+14-\frac{3}{2} x+15$

Simplifying, we get;

$14+15=29$

Thus, the expression $2\left(\frac{3}{4} x+7\right)-3\left(\frac{1}{2} x-5\right)$ is equivalent to 29.

Hence, Option B is the correct answer.

Option C: $2\left(\frac{3}{4} x+7\right)+(-3)\left[\frac{1}{2} x+(-5)\right]$

Let us rewrite the given expression.

$2\left(\frac{3}{4} x+7\right)+(-3)\left[\frac{1}{2} x+(-5)\right]$

Thus, the expression $2\left(\frac{3}{4} x+7\right)-3\left(\frac{1}{2} x-5\right)$ is equivalent to $2\left(\frac{3}{4} x+7\right)+(-3)\left[\frac{1}{2} x+(-5)\right]$

Thus, Option C is the correct answer.

Option D: $2\left(\frac{3}{4} x\right)+2(7)+3\left(\frac{1}{2} x\right)+3(-5)$

Rewriting the expression, we get;

$2\left(\frac{3}{4} x+7\right)+(-3)\left[\frac{1}{2} x+(-5)\right]$

Hence, the expression $2\left(\frac{3}{4} x+7\right)-3\left(\frac{1}{2} x-5\right)$ is equivalent not to $2\left(\frac{3}{4} x\right)+2(7)+3\left(\frac{1}{2} x\right)+3(-5)$

Thus, Option D is not the correct answer.

Option E: $2\left(\frac{3}{4} x\right)+2(7)+(-3)\left(\frac{1}{2} x\right)+(-3)(-5)$

Multiplying the terms within the bracket, we get;

$2\left(\frac{3}{4} x\right)+2(7)+(-3)\left(\frac{1}{2} x\right)+(-3)(-5)$

Hence, the expression $2\left(\frac{3}{4} x+7\right)-3\left(\frac{1}{2} x-5\right)$ is equivalent to $2\left(\frac{3}{4} x\right)+2(7)+(-3)\left(\frac{1}{2} x\right)+(-3)(-5)$

Thus, Option E is the correct answer.
