Step-by-step explanation:
Weight of new born year =4 kg
Its weight increases by the power of 2 in 5 years
So, Weight of bear in 5 yr=weight of bear at present
2
=(4)
2
=16 kg.
Answer/Step-by-step explanation:
1. x*21 = 24*14 (intersecting chords theorem)
21x = 336
x = 336/21
x = 16
2. 27*x = 45² (secant-tangent rule)
27x = 2,025
x = 2,025/27
x = 75
3. (x + 5)*5 = (4 + 6)*6 (Intersecting secants theorem)
5x + 25 = (10)*6
5x + 25 = 60
5x = 60 - 25
5x = 35
x = 35/5
x = 7
4. (4x + 2)*8 = (5x + 1)*7
32x + 16 = 35x + 7
Collect like terms
32x - 35x = -16 + 7
-3x = -9
x = -9/-3
x = 3
Answer:
acceleration = 9.8 m/s^2
Step-by-step explanation:
The problem expects the user to do the rate of change between any two pairs of (time, velocity) from the table, and see that they all render the same value. Notice as well that the rate of change of a difference in velocities divided a difference in time, will render units of acceleration (in this case ![\frac{m}{s^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bs%5E2%7D)
Let's use for example (0 s ,0 m/s) and the following point: (1 s, 9.8 m/s)
the rate of change is: ![acceleration= \frac{9.8-0}{1-0} \frac{m}{s^2} =9.8 \, \frac{m}{s^2}](https://tex.z-dn.net/?f=acceleration%3D%20%5Cfrac%7B9.8-0%7D%7B1-0%7D%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%3D9.8%20%5C%2C%20%5Cfrac%7Bm%7D%7Bs%5E2%7D)
In fact you can use any two pairs of the table, and will get the same result.
So this is the acceleration is ![9.8 \, \frac{m}{s^2}](https://tex.z-dn.net/?f=9.8%20%5C%2C%20%5Cfrac%7Bm%7D%7Bs%5E2%7D)
A (-4,5)
B (-3,1)
C (-5,2)
A'(3,1)
B'(2,5)
C'(4,4)
Answer:
The answer should be 1/12 because a a cube has 6 sides rolling it twice would make it 12.
Hope This Helps!
