Gilbert has 50 drywall screws. He is purchasing more screws. He can purchase up to 6 boxes of screws. Each box of screws contain

s 200 screws. He can't purchase partial boxes. The function that models the number screws Gilbert has is f(b)=200b+50 f ( b ) = 200 b + 50 , where b is the number of boxes he purchases. What is the practical domain of the function?

Answer: \left \{ {b\epsilon \mathbb{N}: b\leq 6} \right \}



Step-by-step explanation:

Given: Gilbert has 50 drywall screws. He is purchasing more screws. He can purchase up to 6 boxes of screws.

Each box of screws contains 200 screws.

The function that models the number screws which Gilbert has is

f(b)=200b+50f(b),  where b is the number of boxes he purchases.

As, he can't purchase partial boxes., therefore b should be a natural number which is less than equal to 6.

Thus, the domain of the function =\left \{ {b\epsilon \mathbb{N}: b\leq 6} \right \}

triangle ABC is isosceles, angle B is vertex angle , AB = 20x -2, AC =25x, and BC =12 x +20. Find x and the length of each side
lisov135 [29]

Length of AB = 18. 92

Length of AC = 26. 15

Length of BC = 32. 552

<h3>How to determine the sides of the triangle</h3>

Using the Pythagorean theorem, we have that

(20 x-2)^2 = (12x + 20)^2 + (25x)^2

Expand the bracket

400x^2- 4 = 144x^2 + 400 + 625x^2

Collect like terms

400x^2 - 144x^2 - 625x^2 = 400 + 4

-369x^2 = 404

Make x^2 subject

x^2 = \frac{404}{369}

x = \sqrt{1.0948}

x = 1. 046

Thus,

Length of AB = 20x -2 = 20(1. 046) - 2 = 18. 92

Length of AC = 25x = 25* 1.046 = 26. 15

Length of BC = 12x + 20 = 12(1. 046) + 20 = 32. 552

HELP PLEASE I WILL GIVE BRAINLIEST AND 35 POINTS!!!!!!!!!!!!!!!!!!!!!!!Which statements are true about the ordered pair (−1, 5)
murzikaleks [220]
The ordered pair (-1,5) is a solution to the system because it makes both equations true.

1) x+y=4
2) x-y=-6

1) -1 + 5 = 4
    5-1 = 4   you can switch the order to make it easier to understand
        so
        4 = 4

2) -1 - 5 = -6
     -1 + -5 = -6 you can change the sign in the middle and make y - 
          so
        -6 = -6
