Y = -4x+2
x = -1
-4(-1) + 2 = /// 6 = y
x = 0
-4(-1) + 2 = /// 2 = y
x=1
-4(1) + 2 = /// -2 = y
x=2
-4(2) + 2 /// -6 = y
Answer:
centre = (- 1, - 3 ) , radius = 6
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² + 2x + 6y = 26 ( collect x and y terms )
x² + 2x + y² + 6y = 26
using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(1)x + 1 + y² + 2(3)y + 9 = 26 + 1 + 9
(x + 1)² + (y + 3)² = 36 ← in standard form
with centre = (- 1, - 3 ) and r = 
= 6
Answer:
Volume of the given oblique cylinder = 36π units³
Step-by-step explanation:
Volume of the oblique cylinder = πr²h
Here, 'r' = Radius of the circular base
'h' = Height of the cylinder
For the given oblique cylinder,
Radius of the circular base = 3 units
Height of the cylinder = 4 units
Volume of the cylinder = π(3)²(4)
= 36π units³
Therefore, volume of the given oblique cylinder = 36π units³
Answer:
Answer: x = 71 degrees. Yes, the ladder meets safety standards
Discussion:
The problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x". For this triangle,
cosx = (side adjacent to angle) / hypotenuse
= 4 / 12
= 1/3
To find "x" take the inverse cosine of each side to find that :
x is approximately 70.52 degrees. That's 71 degrees rounded to the nearest degree.
