Affordable Auto offered to enter people into a drawing for a free car if they shared the company's advertisement on social media. This table gives the total number of times the advertisement was shared since the promotion began. The data can be modeled by a quadratic function.

Length of promotion (days) 2 4 6 8 10 12
Number of shares 1200 3219 6240 10264 15290 21318


What function best models the data?
y=1.2x^2+20.6x+280

y=125.3x^2+183.3

y=1.2x^2+280

y=125.3x^2+257.8x+183.3

Answer:

-20x^4y + 40x^3y^2.

Step-by-step explanation:

-5x^3y(4x-8y)

= -5x^3y * 4x + -5x^3y * -8y

= -20x^4y + 40x^3y^2

Answer:

Remember length times width times height when finding volume.

In non-terms of pi, the answer would be [tex]2[/tex] [tex]ft^2[/tex]

Answer:

Volume is 2ft

Step-by-step explanation:

Multiply the length x width once you find the answer for lengthxwidth.

Multiply the answer you got by height

Answer:

a) Greatest Common factor = 3

b) Greatest Common factor = x

c) Greatest Common factor = xy

Step-by-step explanation:

a)

We can write the equation "3x² - 9x + 12" into three parts and we factor them:

3x² =  [tex]3\times\:x\times\:x[/tex]

9x = [tex]3\times\:3\times\:x[/tex]

12 = [tex]2\times\:2\times\:3[/tex]

Common factor = 3

b)

We can write the equation "5x² + 3x" into two parts and we factor them:

5x² = [tex]5\times\:x\times\:x[/tex]

3x = [tex]3\times\:x[/tex]

Common factor = x

c)

We can write the equation "x²y - xy²" into two parts and we factor them:

x²y = [tex]x\times\:x\times\:y[/tex]

xy² = [tex]x\times\:y\times\:y[/tex]

Common factor = xy or x ⋅ y

You need to add 200 mL of the 55%   to obtain the desired solution

Step-by-step explanation:

x=mixture you need to add

20% * 150 + 55% x = 40%(x + 150)

0.20 * 150 + 0.55x = 0.40(x + 150)

30+0.55x=60+0.40x

0.15x = 30

x=200 mL

Answer:  3

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals of each other.

Answer:

Slope = 3

Step-by-step explanation:

The question is asking us to find the slope of the line that is perpendicular to the line whose slope is -1/3.

Main idea: Perpendicular lines have slopes that are opposite reciprocals.

So our task boils down to finding the opposite reciprocal of -1/3.

First, we change the sign from negative to positive. We get 1/3.

Then, we turn the number over. We get 3.

Therefore, the slope is 3.

Step-by-step explanation:

Answer:

The answer is (-4) and (-7).

Step-by-step explanation:

Now, for common difference (d)

d = a₂ – a₁ = 2 – 5 = -3

d = a₃ – a₂ = (-1) – 2 = -3

Here, common difference is same everywhere.

So, for fourth term or n = 4

aₙ = a + (n – 1) × d

a₄ = 5 + (4 – 1) × (-3)

a₄ = 5 + 3 × (-3)

a₄ = 5 – 9

a₄ = -4

Then, for fifth term or n = 5

a₅ = 5 + (5 – 1) × (-3)

a₅ = 5 + 4 × (-3)

a₅ = 5 – 12

a₅ = -7

Thus, The fourth term is (-4) and fifth term is (-7).

The answer is no, because the Rank Theorem tells us that rank A + dim Nul A = 12 . Since the rank can be at most 10, the null space has to have dimension at least two.
