Answer:
Final velocity is 3
Change in velocity is 4
Initial velocity is 2
Instantaneous velocity is 1
Acceleration is 5
Answer:
Explanation:
Work backward:
1. 2x + 23 = 30
Start:
Multiply the equation by 2:
Subtract 30 from both sides
- 2x - 30 = 7 - 30
- 2x - 30 = -23
Add 23 and 30 to both sides:
2. 3x + 19.5 = 30
Start:
Add 6.5 to both sides:
Multiply by 3:
Distributive property:
3. (10x - 20)/ 5 = 3
Start:
Multiply by 10:
Subtract 20:
Divide by 5:
2x^2 + 4x + 1 = 0
2x^2 + 4x + 1 - 1 = 0 - 1
2x^2 + 4x = -1
X(2x + 4) = -1
X = -1.
2x + 4 = -1
2x + 4 - 4 = -1 - 4
2x = -5
2x/2 = -5/2
X = -5/2.
I believe these are the solutions. If not you can use the quadratic formula to solve for the roots, solutions.
Is there an image attached?
Answer:
Sam is right. shape A which is cylinder has uniform cross section.
Explanation:
what is uniform cross section?
uniform cross section is when cut through an object and the bases are similar.
solution:
For cylinder:
when we cut a cylinder, its in a circle shaped and have similar bases - thus have uniform cross section.
For pyramid:
when we cut a pyramid it is in rectangle shape and this changes as we go up or down the pyramid and does not have uniform cross section.
