Factor r 4 t 4 out of 5 r 8 t 5 − 3 r 4 t 4 . r 4 t 4 ( 5 r 4 t − 3 )
Answer:
Step-by-step explanation:
<u>Given the following data;</u>
Initial velocity = 0 (since the stone is starting from rest).
Final velocity = 32 m/s
Acceleration = g = 10 m/s²
Time = 3.2 seconds
To show that the speed of the stone when it hits the ground is 32 m/s, we would use the first equation of motion;
Where;
- V is the final velocity.
- U is the initial velocity.
- a is the acceleration.
- t is the time measured in seconds.
Substituting into the formula, we have;

<em>Proven: 32 m/s = 32 m/s</em>
Answer:
B)
Step-by-step explanation:
(2x^3+x^2-4x)-(9x^3-3x^2)
2x^3-9x^3+x^2-(-3x^2)-4x
-7x^3+x^2+3x^2-4x
-7x^3+4x^2-4x
<em><u>Division equation is:</u></em>

There are 2816 calories in whole pizza
<em><u>Solution:</u></em>
Given that,
A 14- inch pepperoni pizza is sliced into 8 equal pieces
One slice contained 352 calories
Therefore,
1 slice = 352 calories
Let "c" be the calories
Given that there are 8 equal pieces
<em><u>Therefore, calories in 8 pieces are:</u></em>
Calories in 8 pieces = 8 x calories in 1 piece

Thus the division equation is:

Therefore,

Thus there are 2816 calories in whole pizza
