Answer:
21.27 cm^2
Step-by-step explanation:
Pentru a calcula aria bazei, putem folosi formula lui Heron Matematic aceasta este;
A = √s (s-a) (s-b) (s-c)
Unde s = (a + b + c) / 2
a, b, c se referă la laturile triunghiului
A = (7 + 7 + 7) / 2 = 21/2 = 10,5
A = √10,5 (10,5-7) (10,5-7) (10,5-7)
A = √10,5 (3,5) (3,5) (3,5)
A = √450.1875
A = 21.2176 cm ^ 2, care este de aproximativ
21.22 cm ^ 2
=
( x - 4 )² / ( x + 3 ) ( x + 1 ), restrictions: x ≠ - 3, x ≠ - 1;
Answer:
A )
Answer:
36 inches
Step-by-step explanation:
The ratio is L:W = 4:3 = 48:?
if you divide 48 by 4 you get 12. So now do 12 times 3 to get 36! Whatever you do to one ration do the same to the other, I like to remember it that way.
Answer:
Step-by-step explanation:
5). y = 4 - x²
Table for the points on this function will be,
x -2 -1 0 1 2
y 0 3 4 3 0
Therefore, Domain of the function will be: (-∞, ∞)
And Range of the function will be : (-∞, 2]
7).
This function is defined from the values of x ≥ 1
Table for the input-output values of this function is,
x 1 2 5 10 17
y 2 3 4 5 6
Therefore, Domain of the function will be: [1, ∞)
And Range of the function : [2, ∞)
