Step-by-step explanation:
Pythagoras (for right-angled triangles) :
c² = a² + b²
c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.
c = diagonal = 10 ft
therefore, the width of the rectangle is 10/2 = 5 ft
10² = 5² + b²
100 = 25 + b²
b² = 75
b = length = sqrt(75) = 8.660254038... ft
Answer:
7
Step-by-step explanation:
The centroid divides the median in a 2:1 ratio. Therefore,
AD = 2DM
x + 3 = 2(2x - 1) Remove parentheses
x + 3 = 4x – 2 Add 2 to each side
x + 5 = 4x Subtract x from each side
3x = 5 Divide each side by 3
x = ⁵/₃
AM = AD + DM
= (x + 3) + (2x – 1)
= 3x + 2 Substitute the value of x
= 3 × ⁵/₃ + 2
= 5 + 2
= 7
Length of median AM = 7.
Answer:
In an equation y = a(x - h) + k, the axis of symmetry will be x = h. This is because (h, k) is the vertex, and the parabola will be symmetric on both sides of the vertex.
Best Answer: <span>A radical expression is any expression or equation that contains a square root. The square root symbol indicates the number inside is a radical. The number inside the square root is called the radicand. Variable numbers can also be radical expressions.
Example: </span>√x+y
√16
12+√x
√3*x²
