Answer:
(-5 , 2 )
Step-by-step explanation:
hello :
×-5y=-15
5y = x+15
y = (1/5)x+3 for x= - 5 y = (1/5)(-5) +3 so : y = 2
Answer:c
Step-by-step explanation:
when you set (x-6) and (x-1) to zero you get 6 and 1
(xy)' + (2x)' + (3x^2)' = (4)'
y + xy' + 2 + 6x = 0
xy' = -y -2 -6x
y' = [-y -2 -6x] / x
Now solve y from the original equation and substitue
xy + 2x + 3x^2 = 4 => y = [-2x - 3x^2 + 4] / x
y' = [(-2x - 3x^2 +4) / x - 2 - 6x ] / x
y' = [-2x - 3x^2 + 4 -2x -6x^2 ] x^2 = [ -4x - 9x^2 + 4] / x^2 =
= [-9x^2 - 4x + 4] / x^2
The formula for the surface area of cone is:
Surface Area of Cone = π * r * l + π * r^2 , where l = slant height
Substituting the given values:
282.74 ft^2 = 3.14 * 5 ft * l + 3.14 * (5 ft)^2
<span>l = 13 ft</span>
