A truss or staircase frame from the custom steel products cost $2.25 for each rod plus $50for shipping and handling

Answers

The equation that can be used to represent the cost paid for the staircase frame is 50 + 2.25x

Based on the information given, let the number of rods be represented by x.

Fixed cost = $50

Variable cost = $2.25 × x = 2.25x

Therefore, the equation to calculate the total cost will be:

= Fixed cost + Variable cost

= 50 + 2.25x

Therefore, the equation to represent the fact that the staircase frame cost $2.25 for each rod plus $50 for shipping and handling is 50 + 2.25x

Problem 2: A ball is dropped from rest from a height of 6 meters, Find the time it takes the ball
to fall. Find the velocity of the ball just before it hits the earth. Assume no air resistance and
that acceleration due to gravity (g) is 9.8 m/s/s.

Answers

Answer:

1.11 s , 10.88 m/s

Step-by-step explanation:

Initial velocity and air resistance = 0

Time to fall : s = 1/2 gt²

6 = 1/2 * 9.8 * t²

t² = 1.224

t = 1.11 s

final velocity = initial velocity + gt

                    = 0 + 9.8 * 1.11

                    = 10.88 m/s

-8 is a negative number, which means many operations don't work the same on it. Subtracting a positive number from a negative number will give you the same result as adding the two positive numbers (in this case, 8 + 9), though the answer will also be negative. Hope this helps!
