10 points <br> Can someone please do number 4
Andrei [34K]

This question wants to know the domain.  For example: (2,4) 2 is the domain and 4 is the range.

Then, they want you to solve by finding X the range when x =-1

x-4/x^2+5x-36

Put -1 everytime you see x

-1-4/-1^2+5(-1)-36

-5/1+(-6)-36

-5/-41 This is the range.

mezya [45]

Answer:

x = 5/7

Step-by-step explanation:

4 (0.25 - 2) = x - 0.75 (16 - 8x)

1 - 8 = x - 12 + 6x

1 - 8 + 12 = x + 6x

5 = 7x

5/7 = x

Asssesmenttt lasttt......
ratelena [41]

Answer:

<em>( About ) 1.77 seconds; Option B</em>

Step-by-step explanation:

We are given the equation h ( t ) = - 16t^2 + 50, so in order to determine the time let us determine the x - intercept for y ⇒ 0;

- 16t^2 + 50 = 0,

- 16t^2 = - 50,

t^2 = 25 / 8,

Thus t ⇒ √ ( 25 / 8 ), and t ⇒ - √ ( 25 / 8 ),

t ⇒ ( 5√2 )/ 4, and - ( 5√2 )/ 4,

But time is represented only by a positive value, thus

t ⇒ ( 5√2 )/ 4 = 1.767766953......., ( About ) 1.77 seconds

<em>Answer; ( About ) 1.77 seconds; Option B</em>
