Answer:
22.2 m.
Step-by-step explanation:
They walk in a right triangle.
First they walk 7 then 6 m = 13 m.
We calculate the distance of the diagonal using Pythagoras:
x^2 = 6^2 + 7^2 = 85
x = √85
= 9.2 m. yo nearest 1/10.
Answer is 13 + 9.2
= 22.2 m.
To determine the equation of the parabola with the given features above, we need to understand or know what are the significance of those values. The directrix is a line that is perpendicular to the axis of symmetry of a curve. A parabola is defined by its focus and the directrix. The parabola is a group of points where the distance to its focus is equal to the distance to its directrix. So, the directrix for this case is all points (x, -1). By using the distance formula, we construct the equation.
√((x-0)^2 + (y-1)^2) = √((x-x)^2 + (y+1)^2)
x^2 + (y-1)^2 = (y+1)^2
x^2 + y^2 - 2y+1 = y^2 +2y + 1
x^2 - 2y = 2y
x^2 = 4y
y = x^2/4
Answer:
2
Step-by-step explanation:
It's 2 because the numbers go up by 2 each time the mean is identified meaning that the mean of each is 4.
The greatest common factor of 18 and 48 is 6.
