Answer:
The opening is a rectangle
AC = 18 in
BD = 18 in
Step-by-step explanation:
9+9 = 18
since the diagonals are equal, it is a rectangle.
Answer:
If the kite has an 11 ft line attached to it and it casts an 8 feet shadow, we will have a rectangle triangle (see picture below).
To find the height x of the kite, we can apply the Pythagorean theorem.
x² = 11² - 8²
x² = 121 - 64
x² = 57
x =√57 Step-by-step explanation:
Answer:
k = -10
Step-by-step explanation:
-9 + k/10 = -10
-10/10 = -1
-9 + -1 = -10
k = -10
Consider this option:
1. rule: Circle is the locus of the points which are on the same distance from the given point. Common view of the equation is: (x-a)²+(y-b)²=r², where r - the distance from the given point to the described locus, a&b - coordinates of the given point.
2. using item 1:
(x+2)²+(y-1)²=3² or (x+2)²+(y-1)²=9.
The volume of a triangular prism is equal to :
area of the base x height
the area of the base :
![10 \times 4 \div 2 = 40 \div 2 = 20](https://tex.z-dn.net/?f=10%20%5Ctimes%204%20%5Cdiv%202%20%3D%2040%20%5Cdiv%202%20%3D%2020)
so the volume is
![20 \times 8 = 160](https://tex.z-dn.net/?f=20%20%5Ctimes%208%20%3D%20160)
the answer is 160m^3
good luck
