Step-by-step explanation:

Mid point formula ,

x = (x1+x2)/2 , y = (y1+y2)/2

x = 1 , y = 4

therefore ,midpoint is (x, y)= (1,4)

19)  15/a = 3/2 

Start by cross multiplying....

3a = 30 

Divide both sides 3 

a = 10 

21)   2/7 = 4/d 

        2d = 28
       
        d= 14 

23)  8/p = 3/10

       
80 = 3p
         p = 26.66

25)  2 / -5 = 6/t
        2t = -30

      t = -15

What happens to the value of the expression 2t/t as t decreases
anyanavicka [17]

Answer:

  it stays the same until t=0, where it is undefined

Step-by-step explanation:

2t/t = 2 . . . . when t ≠ 0

2t/t = undefined when t = 0.

The value of t can increase or decrease and the value of the ratio remains the same. The value has a "hole" at t=0, where it is undefined. Otherwise, its value is always 2.

90 POINT QUESTION!!!
Aleks [24]

Answer: 9.19 ft

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.  

Sin α = opposite side / hypotenuse  

Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is the height of the top of the ladder above the ground.

Replacing with the values given:  

Sin 45 = x/ 13

Solving for x  

sin45 (13) =x  

x= 9.19 ft

Feel free to ask for more if needed or if you did not understand something.
