Answer:

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

(f - g) (x)=-x^2 +5x +1

Step-by-step explanation:

We have the following functions:

f(x)=3x +2\\ and g(x) = x^2 -2x +1

First we find (f + g) (x)

To find (f + g) (x) we must add the function f(x) with the function g(x)

(f + g) (x)=3x +2 + x^2 -2x +1

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

Now we find (f - g) (x)

To find (f - g) (x) we must subtract the function f(x) with the function g(x)

(f - g) (x)=3x +2 - (x^2 -2x +1)

(f - g) (x)=3x +2 - x^2 +2x -1

(f - g) (x)=-x^2 +5x +1

Write an exponential equation that represents the given situation. You invest $1000 and it increases 12% each year. Can you teac
IrinaK [193]

Answer:

FV= 1,000*(1.12^n)

Step-by-step explanation:

Giving the following information:

Initial investment= $1,000

Increase rate= 12% = 0.12

We need to formulate an exponential equation to show the value in n years.

<u>To calculate the Future Value, we need to use the following formula:</u>

FV= PV*(1+i)^n

Being:

FV= Future Value

PV= Initial Investment

i= increase rate

n= number of periods

FV= 1,000*(1.12^n)

<u>For example, for one year:</u>

FV= 1,000*(1.12^1)

FV= $1,120

For 3 years:

FV= 1,000*(1.12^3)

FV= $1,404.93

The top of the desk is shaped like a trapezoid the bases of the trapezoid are 26.5 and 30 cm long the area of the desk is 791 CM
kotegsom [21]

Answer:

28 cm

Step-by-step explanation:

Given that :

Area = 791 cm

Base, b1 = 26.5 cm

Base, b2 = 30 cm

Area, A of trapezoid :

A = 1/2 (a + b) h

Where a and b are the bases ;

791 = 1/2(26.5 + 30)h

791 = 0.5(56.5)h

791 = 28.25h

h = 791 / 28.25

h = 28 cm
