Answer:
x^2+y^2 = 3^2
Step-by-step explanation:
We need to eliminate the parameter t
Given:
x = 3 cos t
y = 3 sin t
Squaring the above both equations
(x)^2=(3 cos t)^2
(y)^2 =(3 sin t)^2
x^2 = 3^2 cos^2t
y^2=3^2 sin^2t
Now adding both equations
x^2+y^2=3^2 cos^2t+3^2 sin^2t
Taking 3^2 common
x^2+y^2=3^2 (cos^2t+sin^2t)
We know that cos^2t+sin^2t = 1
so, putting the value
x^2+y^2=3^2(1)
x^2+y^2 = 3^2
Hence the parameter t is eliminated.
Answer:
256.56ft³
Step-by-step explanation:
V₍cone₎= πr²(h/3)
=π×(7)²×(5/3)
=(3.14)×(49)×(1.67)
=256.4ft³
You require to find the perimeter of the carpet.
Perimeter = 2xLength + 2xWidth
Perimeter = 2 x 4 + 2 x 2ft 6 ins.
Perimeter = 8 + 5 ft
Perimeter = 13ft
13ft of braid is required.
Hope this helps:-)
Given:
The function is
The secant line passing through (-4,f(-4)) and (2,f(2)).
To find:
The equation of the secant line.
Solution:
We have,
At x=-4,
At x=2,
The secant line passes through the points (-4,-66) and (2,6). So, the equation of the secant line is
On further simplification, we get
Therefor, the equation of the secant line is .
(3posts x 15 centimeters) + 2gaps x Xcentimeters = 153centimeters
45 + 2X = 153
2X = 108
X = 54 centimeters
