Step-by-step explanation:
It is a right angle triangle. Hypotenuse is 10, because it was 15 ft tall. 10 squared is 100. 5 squared is 25. 100 - 25 = 75. Sqrt 75 = 9
15-5=10
X=10ft

Step-by-step explanation:
x^2-8x+k is a quadratic expression of the form ax^2 + bx + c. Here a = 1, b = -8 and c = k. Focus on x^2-8x and complete the square as follows: Take half of the coefficient of x (that is, take half of -8) and square the result:
(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4): (x -4)^2.
Thus, k = 16 turns x^2-8x+k into a perfect square.

Answer:
Option D. Divide 15 by 2
Step-by-step explanation:
we know that
To find the y-coordinate of the midpoint of a vertical line, adds the y-coordinates of the endpoints and divide by two
we have the endpoints
(0,0) and (0,15)
The y-coordinate of the midpoint is (0+15)/2=15/2=7.5
therefore
Divide 15 by 2
Answer:
the answer is to count by hands ( A ) and divide 15 by 2 ( D )

1. You have that the formula for calculate the area of a triangle is:
A=bh/2
Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.
bh/2=124
bh=124x2
bh=248
2. The problem asks for the new area of the triangle if its base was half as long and its height was three times as long. Then, you have:
Base=b/2
Height=3h
3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:
A'=bh/2
(A' is the new area)
A'=(b/2)(3)/2
A'=3bh/4
4. When you substitute bh=248 into A'=3bh/4, you obtain:
A'=186 units²
The answer is: 186 units²
