What’s the rest of the question
Answer:
≈ 11.4 m
Step-by-step explanation:
The diagonal splits the rectangle into 2 right triangles , with legs 7 and 9 and the diagonal the hypotenuse.
Using Pythagoras' identity with h as the diagonal, then
h² = 7² + 9² = 49 + 81 = 130 ( take the square root of both sides )
h = ≈ 11.4 m ( to the nearest tenth )
Answer:
12
Step-by-step explanation:
It's simple, you divide 60 by 5 to get 12, so the scale factor of the triangle is 12
Step-by-step explanation:

After a dilation of 2 (about the origin), all coordinates will be doubled.
Thus the image is 2 time the original matrix, or
-6 -4 -1
8 2 10
#37
a12 means the element on the first row, and the second element from the left.
The question does not indicate which matrix is named "a", but by elimination, we will assume it is the first matrix in the matrix equation.
Isolating the elements 12 (first row, second element) in the equation, we get
a12+5 = 1
which tells us that
a12=1-5 = -4
The 6 is in the ones place. :)))
