Someone please help me on both the questions!!!

bonufazy [111]

Step-by-step explanation:

al nth term:

numerator:

$= {n}^{2}$

denominator:

$= n + 1$

so nth term :

$= \frac{ {n}^{2} }{n + 1}$

b). 1; 11; 27; 49

first difference: 10; 16; 22

second difference :6

formula for 1st difference:3a+b

formula for 2nd difference:2a

Therefore:

2a=6

a=3

3a+b=10

sub in a

3(3)+b=10

9+b=10

b=1

sub into quadratic formula

${an}^{2} + bn + c$

$(3) {(1)}^{2} + (1)(1) + c = 1$

$3(1) + 1 + c = 1$

$3 + 1 + c = 1$

$4 + c = 1$

$c = - 3$

So Tn:

$3 {n }^{2} + 1n - 3$

If (3a + 3b + 1) (3a + 3b - 1) = 80, then a + b =

seropon [69]

Answer:

a+b = 4 $\sqrt{3}$

Step-by-step explanation:

3(a + b)^2 = 81

(a + b)^2 = 27

a + b = sq rt 27

a + b = $\sqrt{9}$ · $\sqrt{3}$

a + b = 3 $\sqrt{3}$

The domain and range of each given relation is:

1. Domain - {3, 4, 5, 6, 7}

Range - {5, 15, 20, 25, 30}

2. Domain - {-1}

Range - {2, 4, 6, 8, 10}

3. Domain - {-6, -5, -3, -2}

Range - {1, 0, -1, -2, -3}

<h3>What is the Domain and Range of a Relation?</h3>

A pair of values of a relation is represented as (x, y).
The domain of a relation consists of all x-values.
Range consist of all y-values.

Thus, the domain and range of each given relation is:

1. Domain - {3, 4, 5, 6, 7}

Range - {5, 15, 20, 25, 30}

2. Domain - {-1}

Range - {2, 4, 6, 8, 10}

3. Domain - {-6, -5, -3, -2}

Range - {1, 0, -1, -2, -3}

Clarice Sloan is a shift supervisor for Ace

The net pay is the amount left after taxes and deductions have been removed from the gross pay.

Her monthly gross pay is: $4111.93

The deductions are:

$\mathbf{FIT = \$102}$

$\mathbf{SIT = 3.2\%}$

$\mathbf{CIT = 1.8\%}$

Let her gross pay be x.

So, we have:

$\mathbf{Net = x - FIT - x \times SIT - x \times CIT}$

So, we have:

$\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}$

Express percentage as decimals

$\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}$

$\mathbf{3804.33 = x - 102 - 0.032x - 0.018x}$

Add 102 to both sides

$\mathbf{3906.33 = x - 0.032x - 0.018x}$

$\mathbf{3906.33 = 0.95x}$

Divide both sides by 0.95

$\mathbf{4111.93 = x}$

Rewrite as:

$\mathbf{x = 4111.93 }$

Hence, her monthly gross pay is: $4111.93
