Hello! Essentially you are trying to find a linear function. For example, a linear function is a function that increases or decreases in some type of relationship between each pair consistently. To answer your question, one example could look like this...

Lastbenchstudent basically nailed the linear equation but I could elaborate from his work and answer your question in a different way.

A = 3, B = 18

A = 2, B = 9

A = 1, B = 4.5

To explain my answer, I basically divided B every time A decreased. As A decreased by 1, B decreased by half the amount!

a=1, b =18

a=2, b = 9

a = 3 , b = 6

Find the nth term of this quadratic sequence 4 9 16 25 36

TEA [102]

Answer:

Step-by-step explanation:

a₁ = 4 = 2² = (1 + 1)²

a₂ = 9 = 3² = (2 + 1)²

a₃ = 16 = 4² = (3 + 1)²

a₄ = 25 = 5² = (4 + 1)²

a₅ = 36 = 6² = (5 + 1)²

Therefore:

aₙ = (n + 1)² = n² + 2n + 1

Find the mean of the data summarized in the given frequency distribution. A company had 110 employees whose salaries are summari

mafiozo [28]

Answer:

$\bar X= \frac{1930055}{110}=17545.95$

Step-by-step explanation:

For this case we can construct the following table in order to find the mean for the grouped data:

Interval Frequency (fi) Midpoint (Xi) Xi *fi

5001-10000 27 7500.5 202513.5

10001-15000 23 12500.5 287511.5

15001-20000 12 17500.5 210006

20001-25000 18 22500.5 405009

25001-30000 30 27500.5 825015

Total 110 1930055

And the mean is calculated with the following formula:

$\bar X= \frac{\sum_{i=1}^n x_i f_i}{n}$

Where $n = \sum_{i=1}^n f_i = 110$

So then if we replace into the formula we got:

$\bar X= \frac{1930055}{110}=17545.95$

Use the remainder theorem to find the remainder for each of the following divisions. (x²+3x+1)/(x+2)

Jet001 [13]

Answer:

The remainder of this division is -1.

Step-by-step explanation:

Given data in the question:-

Dividend= $x^2+3x+1$

Divisor= $x+2$

Solution:-

To find the remainder using the remainder theorem. We have to substitute -2 in the dividend and on solving that we will get the remainder.

We got -2 from the divisor when we equate the divisor to 0.

x+2=0

x=-2

$p(a)=x^2+3x+1\\$

Substituting -2 in above written equation.

$p(-2)=(-2)^2+3(-2)+1\\p(-2)=4-6+1\\p(-2)=5-6\\p(-2)=-1$
