Answer:

This question is asking you to find the ending position of a shape (particle) that is moving horizontally along the horizontal axis by finding its velocity with the equation shown. When t=0, the shape is 4 units to the left of the vertical axis, so it wants you to find where on the horizontal axis the shape is when t = 8. Hope this helped!!!

Answer:

(C) 16 units to the right

Step-by-step explanation:

Position is the integral of velocity with respect to time:

x = ∫ v dt

x = ∫ (t − ∛t) dt

x = ½ t² − ¾ t^(⁴/₃) + C

At time t = 0, x = -4.

-4 = ½ (0)² − ¾ (0)^(⁴/₃) + C

-4 = C

So the position equation is:

x = ½ t² − ¾ t^(⁴/₃) − 4

At time t = 8:

x = ½ (8)² − ¾ (8)^(⁴/₃) − 4

x = 32 − 12 − 4

x = 16

The particle is 16 units to the right of the origin.

On the first day of​ June, there were about 17.71 h of daylight in a city. Five months​ later, there were about 5.30 h of daylig
Andru [333]

Answer:

Percentage increases and decreases, are found by setting the problem up proportionally.

 

You are trying to find what percentage of 17.37 is 8.30 first.

 

so What %/100 = 8.30/17.37

 

Now define a variable:

 

Let x = What%  

 

x/100 = 8.30/17.37

17.37x = 830

x = 830/17.37

x ≈ 47.78

 

8.30 is approximately 47.78% of 17.37, so the percentage decrease is 100% - 47.78% = 52.22%

The percentage decrease is approximately 52.22%
