The product of the matrices is an identity matrix. Therefore, X and A are inverse of each other.
The matrices are given as:
To check the matrices are inverse, we calculate their products.
Multiply the rows of A by the column of X.
This gives
The product of A and X is an identity matrix.
This means that; both matrix are inverse of each other

Answer:
5.1cm
Step-by-step explanation:
volume of hemisphere = 1.07cm³
9.2-1.07 = 8.13
volume of cylinders = 8.13cm³
height of cylinder = 4.04cm
total height of gizmo = 4.04+0.8=4.84
4.84/sin(72) = 5.1cm
Answer:
positive infinity bc it is going up
Answer:
y = 4x - 3
Step-by-step explanation:
A parallel line will have the same slope so the slope will remain 4. To fine the new y-intercept, we can substitite the point we are given.
1 = 4(1) + b
1 = 4 + b
-3 = b
Now, we can create the new equation with the information we found.
y = 4x - 3
Best of Luck!
Radius is equal to 1/2 the diameter. The radius is 14 (28/2=14)
With your formula:
c=2*14
c=28
HOWEVER I believe you meant
c=2(pi)r
In which
c=2(pi)14
c=28(pi)
In this instance for pi we can use 3.14 since we will be rounding anyway, so
c=28*3.14
c=87.92
Rounded to be
c=88
Note:
If we didn’t round pi out to 3.14 we would have gotten 87.964594...
