Answer:
The Pythagorean theorem formula is
a²+b²=c²
Step-by-step explanation:
Here's an example
a²+b²=c²
8²+6²=c²
64+36=c²
100=c²
c=√100
Hope I could help
Answer:
h = 16x
Step-by-step explanation:
The volume of a sphere and a cone is same such that,
We have, r = x, R = (1/2)x, h= ? (height of the cone)
So,
So, the height of the cone is equal to 16x.
16x8.5x10.5=1428in
so then u multiply by 3 and that would equal 4,284
so yes therefore u would triple the demsions
The circle equation is in the format (x – h)² + (y – k)² = r², with the center being at the point (h, k) and the radius being "r".
QUESTION 11.
Equation x²+y²+10x-14y-7 =0 can be rewritten as: x²+10x+25 + y² -14y + 49 -7 - 25 - 49=0
It can be factories as (x + 5)² + (y – 7)² = 9²
Therefore the radius equals 9 and the center is (-5,7)
QUESTION 12.
From equation (x + 4)² + y² = 121
The radius equals √121 = 11 and the center is (-4,0)
QUESTION 13.
As there are missing information in the question, I can't assist. However, you can use the general circle equation (x – h)² + (y – k)² = r² to solve the question.
Finally equations 14 & 15 aren't linear.
Hope that helps you :)
