Jessica wants to make a ramp using a board so that she can ride her bike onto the front porch. the ramp must reach from the ground to the floor of the porch, which is 212 ft above the ground. jessica has decided that the ramp cannot have an incline of more than 35°.
what length board should jessica buy if she uses the maximum angle of incline?

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

  the correct choice is marked

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
