Answer:
Volume = 1.9 in3
Step-by-step explanation:
If the perimeter of the square base is 5 inches, we have that:
Perimeter = 4 * side
5 = 4 * side
side = 1.25 in
Then, to find the volume of the pyramid, we can use the formula:
Volume = (1/3) * side^2 * height
So we have that:
Volume = (1/3) * 1.25^2 * 3.6
Volume = 1.875 in3
Rounding to nearest tenth, we have Volume = 1.9 in3

The first thing we are going to do in this case is find the slope of the GH line.We have then:
 m = (y2-y1) / (x2-x1)
 Substituting values:
 m = (- 2-1) / (2 - (- 4))
 m = (- 3) / (6)
 m = -1 / 2
 Then, the generic equation of the line is:
 y-yo = m (x-xo)
 Since the lines are parallel, then the slope is the same
 m = -1 / 2
 The line passes through point J, that is:
 (xo, yo) = (1, 3)
 The equation of the line will then be:
 y-3 = (- 1/2) (x-1)
 Rewriting:
 y-3 = (- 1/2) x + 1/2
 y = (- 1/2) x + 1/2 + 3
 y = (- 1/2) x + 7/2
 The points that pass through this line are:
 (-3, 5)
 5 = (- 1/2) (- 3) +7/2
 5 = 3/2 + 7/2
 5 = 10/2
 5 = 5
 (3, 2)
 2 = (- 1/2) (3) +7/2
 2 = -3 / 2 + 7/2
 2 = 4/2
 2 = 2
 (5, 1)
 1 = (- 1/2) (5) +7/2
 1 = -5 / 2 + 7/2
 1 = 2/2
 1 = 1
 Answer:
 (-3, 5)
 (3, 2)
 (5, 1)
        
                    
             
        
        
        
Answer:
The value of x is 2
Step-by-step explanation:
Diameter = 2r -------------------------------------------------------------------(1)
where r is the radius
The value of the diameter = 32 m   and  radius is given to be 4(x+2)
substitute the above into equation (1)   and then solve for x
32  =  2 [ 4(x + 2)]
first open the inner bracket
32 = 2[4x + 8}
then open the outer bracket
32 = 8x + 16
subtract 16 from both-side of the equation
32 - 16 = 8x +16 - 16
16 = 8x
Divide both-side of the equation by 8
16/8  = 8x/8
2 = x
x = 2
Therefore, the value of x is 2
