Answer:
The radius is 19.42 inches.
Step-by-step explanation:
Start with the formula for finding the circumference of a circle, which is C=2
r.
Then, derive the formula in order to find the radius, which the formula should then look like r= C/2.
Finally, plug in the corresponding numbers, which is r= 122 inches/ 2. The final answer is 19.42 inches.
Answer:
64
Step-by-step explanation:
1) y= -4x+c
2) y= 3x+c replace x and y to find c , 5=3(2)+c
C= -1
Y=3x-1
3) find slope first m=y2-y1/x2-x1 = 0-(-1)/-2-1 = 1/-3 and now you have y= -1/3x+c to find c just replace any of the given points , 0= -1/3(-2)+c
C= -2/3 and so y= -1/3x-2/3
4) DO THE SAME STEP AS NUMBER 3 and enjoy!

Step-by-step explanation:
7 x 9 x 11 =693
Answer:
True
Step-by-step explanation:
Every orthogonal matrix is invertible. This is a true statement.
Orthogonal matrices are square matrix whose rows and columns are orthogonal unit vectors.
In an orthogonal matrix columns are linearly independent and since the columns are linearly independent the matrix will be matrix will be invertible. This is according to invertible matrix theorem.
