(5x^2 + 3x -7) - (3x^2 - 2x + 1)

5x^2 + 3x -7 - 3x^2 + 2x - 1

5x^2 - 3x^2 + 3x +2x - 7 - 1

Find the rule and the graph of the function whose graph can be obtained by performing the translation 3 units left and 2 units d
Vsevolod [243]

Let

g(x)--------> the translation of the function f(x)

we know that

the rule of the translation is

3 units left and 2 units down

that means

(x,y)-------> (x-3,y-2)

so

In the function f(x) the point (0,0) is equal at the point  (-3,-2) in the function g(x)

therefore

the function g(x) is equal to

g(x)=f(x+3)-2

g(x)=(x+3)^{3} -2

<u>The answer is</u>

a) the rule of the translation is (x,y)-------> (x-3,y-2)

b) The graph in the attached figure

Help me plssssssssssssssssssssssssssssss
Naddika [18.5K]

Answer: See explanation (btw, the answer is always in bold letters)

Step-by-step explanation:

1.) 1 gallon for $1.99

1/2 gallon for $0.98

1 gallon would be 0.98 × 2 = <em>1.96</em>

2 gallons for $3.98

1 gallon would be 3.98 ÷ 2 = 1.99

2.) 621 ÷ 4 = 155.25

He pays $155.25 each payment!

3.) V = s³

s = 3

V = 3³

3 × 3 × 3 = 27

V = 27 m³

4.) This is a rectangle; the area of a rectangle is l × b.

L = 6.9

l × b = a

6.9b = 28.29

Divide both sides by 6.9

b = 4.1

The missing length is 4.1 m

5.) False

The weekly salaries of a sample of employees at the local bank are given in the table below. Employee Weekly Salary Anja $245 Ra
evablogger [386]

The variance for the data is  17,507. 5.

Given

The weekly salaries of a sample of employees at the local bank are given in the table below.

Employee Weekly Salary Anja $245 Raz $300 Natalie $325 Mic $465 Paul $100.

<h3>Variance</h3>

Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.

The mean value of the salaries of employees is;

\rm Mean= \dfrac{245+300+325+465+100}{5}\\\\Mean=287

The variance is given by;

\rm  Variance=\sqrt{\dfrac{(245-287)^2 +(300-287)^2 +(325-287)^2 +(465-287)^2 +(100-287)^2}{5-2}} \\\\Variance = 132.316}\\\\On \ Squaring \ both \ the \ sides\\\\Variance^2=17,507. 5

Hence, the variance for the data is  17,507. 5.
