Answer:

1.) 4.87831517751

2.) 12.124355653

Step-by-step explanation:

A.)

The diagonal is 4.87831517751 FT long.

The diagonal equals the square root of the width squared plus the height squared.

Square root of 2 is 1.41421356237

Square root of 12 is 3.46410161514

3.46410161514 + 1.41421356237 = 4.87831517751 .

B.)

The diagonal is 12.124355653 CM long.

The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3.

Square root of 3 is 1.73205080757

1.73205080757 x 7 = 12.124355653

4n^(2)+4n=3 Please help with the work

Kaylis [27]

Answer:

n= 1/2 ( $\frac{1}{2}$ ) or (0.5)

AND

n= -3/2 ( $-\frac{3}{2}$ ) or (-1.5)

Step-by-step explanation:

4n^2+4n=3

step1: move 3 to the other side and make the equation equal to zero.

4n^2+4n-3=0

step2: factorise the equation.

(2n-1)(2n+3)=0

step3: make each bracket equal to zero.

2n-1=0

2n+3=0

step4: solve for n values.

1. 2n-1=0

(add 1 for both sides)

2n=1

(divide by 2 for both sides)

n= 1/2 ( $\frac{1}{2}$ ) or (0.5)

2. 2n+3=0

( subtract 3 for both sides)

2n=-3

(divide by 2 for both sides)

n= -3/2 ( $-\frac{3}{2}$ ) or (-1.5)

Given the functions j(x) = x2 + 3 and k(x) = x2 − x + 4, which operation results in a 2nd degree polynomial?

GrogVix [38]

Addition is the correct answer.

x^2 is the part where you get the second degree term. If you add x^2+x^2 you get 2x^2. If you subtract x^2-x^2 you get 0. If you multiply x^2*x^2 you get x^4, which is a fourth degree term

Which answers describe the end behaviors of the function modeled by the graph? f(x)=4 1/3x+3 , Select each correct answer.

bezimeni [28]

Answer:

As x decreases without bound, f(x) approaches the line y=3 .

As x increases without bound, f(x) increases without bound.

Step-by-step explanation:

From the given graph f(x), we can see that

When x increases the value of y also increases

When x decreases the y values goes close to 3 but it does not cross 3

As x goes to positive infinity , y approaches positive infinity

As x increases without bound, f(x) increases without bound.

As x goes to negative infinity, y values approaches +3

As x decreases without bound, f(x) approaches the line y=3
