Answer:
D
Step-by-step explanation:
To obtain vertex form from the given equation use the method of completing the square
given 8y + x² = - y² - 181 + 26x
rearrange having the x terms and y terms together
add y² to both sides
8y + x² + y² = - 181 + 26x ( subtract 26x from both sides )
x² - 26x + y² + 8y = - 181
add (half the coefficient of the x/y terms )² to both sides
x² + 2(- 13)x + 169 +y² + 2(4)y + 16 = - 181 + 169 + 16
completing the square on both the x and y terms
(x - 13)² + (y + 4)² = 4 → D
Answer:
The final velocity v is 21.74 m/s.
Step-by-step explanation:
Given:
To find:
Solution:
As we know the third equation of motion is represented as
Substituting the values u, a and s in the above equation we get
I think you are missing information to solve this problem. Should there me an image attached to this question.
Either way, to solve for the label, the label would most likely me a rectangle when laid flat.
It's dimensions would be length x height.
Where height is most likely "h"
and
length is most likely the circumference (2πr)
Thus the possible answers are either:
B or C
I can't answer it until I see an image when more detail.
Hope this helps!
