Answer:
The answer to your question is:
Step-by-step explanation:
24.-
y = 5x - 6
x + 5y = 5 5y = - x - 5 y = -(1/5) x - 1
Because of the slopes "5" and "-1/5" the lines are perpendicular.
25.- 2x + y = 10 y = -2x + 10 slope = -2
-6x - 3y = 3 -3y = 6x + 3 y = -2x - 1 slope = -2
x - 2y = 8 -2y = - x + 8 y = (1/2) x - 4 slope = 1/2
Lines a and b are parallels and perpendicular to c
Given
Your family has a circular swimming pool.
The radius of the pool is 9 feet and and its depth is 4 feet.
Find out the volume of the pool.
To proof
As depth is given in the question that means the shape of the swimming pool
is cylinder.
Formula
where r = radius
h = height
now
radius of the pool is 9 feet and and its depth is 4 feet.
put all the values in the above equation
we get
use 3.14 to approximate pi
we get
= 1017.4 ( approx )feet²
Hence proved
1/2n + 15 = 9 <== ur equation
1/2n = 9 - 15
1/2n = - 6
n = -6 * 2
n = - 12 <== ur solution
