Answer:

see explanation

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = width × length

let width be w then length is 2w + 3 ( 3 more than twice the width ), then

A = w(2w + 3) ← distribute

   = 2w² + 3w

When w = 4 , then

A = 2(4)² + 3(4)

   = 2(16) + 12

    = 32 + 12

     = 44 ft²

Determine the domain and range of the quadratic function. (Enter your answers using interval notation.) f(x) = −4(x + 1)2 − 4
zavuch27 [327]

Answer:

Domain -∞ < x < +∞

Range f(x) ≤ - 4

Step-by-step explanation:

The given quadratic function is f(x) = - 4 (x + 1)² - 4

Now, we have to find the domain and range of the quadratic function.

Now, it is clear from the given function that f(x) will have real value for all real value of x.

Therefore, the domain of the function is -∞ < x < +∞ (Answer)

Now, (x + 1)² is always ≥ 0

i.e. (x + 1)² ≥ 0

⇒ - 4 (x + 1)² ≤ 0 {Since the inequality sign changes for multiplying both sides of the equation by a negative term}

⇒ - 4 (x + 1)² - 4 ≤ - 4

⇒ f(x) ≤ - 4

Therefore, this is the required range of the function f(x). (Answer)

Find an angle between 0 and 2pi coterminal with 35pi/6
Leona [35]
For the answer to this question, we have to solve it step by step.
We have to divide both sides by 35.<u>
35π</u> = <u>35(180)</u><u>
</u> 35        35
<u>
</u>= 1050°

1050° - 360° - 360° = 330°
If you would graph it, it would be -30 ° and it is coterminal

I hope my answer helped you somehow
