Answer:
Length of segment PZ = 6 units
Step-by-step explanation:
As per theorem of intersecting chords in a circle ;
"Product of lengths of line segments on each chord are equal".
From the figure attached,
Chords XY and WZ are intersecting at point P in a circle.
By theorem; XP × PY = WP × PZ
7 × 12 = 14 × PZ
PZ = 
PZ = 6 units
Therefore, length of the segment PZ = 6 units.
Answer:
x = 1/3
Step-by-step explanation:
-12x + 12 = 4 - 15x + 9
Combine like terms
-12x +12 = -15x+13
Add 15x to each side
-12x+12 +15x = -15x+15x+13
3x+12 = 13
Subtract 12 from each side
3x+12-12 = 13-12
3x = 1
Divide by 3
3x/3 = 1/3
x = 1/3
Answer:

Answer:
x=4
Step-by-step explanation:
-5(4-x)=-5x+20
We simplify the equation to the form, which is simple to understand
-5(4-x)=-5x+20
Reorder the terms in parentheses
+(-20+5x)=-5x+20
Remove unnecessary parentheses
-20+5x=-5x+20
We move all terms containing x to the left and all other terms to the right.
+5x+5x=+20+20
We simplify left and right side of the equation.
+10x=+40
We divide both sides of the equation by 10 to get x.
x=4
By my calculations id say its 0.5 m/s^2.
