It's quite difficult, almost impossible to write all steps to solve a 3x3 matrix.
However, I will give you te answer that is determinant (Matrix)=54
Answer:
6 : 1
Step-by-step explanation:
A unit rate has to be "a number to 1" or "x:1". Here we have a number to 1/4. Multiply both numbers by 4 so the 1/4 becomes 1.
3/2 * 4 = 12/2 = 6
1/4 * 4 = 1
3/2 : 1/4 is the same as 6 : 1

Answer:
24 cm
Step-by-step explanation:
The altitude from the centre to the chord is 5 cm and bisects the chord.
The radius of the circle is 26 cm ÷ 2 = 13 cm
There is a right triangle formed with legs 5 and x ( x is half the chord )
The hypotenuse is the radius, then using Pythagoras' identity
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x =
= 12
Then
length of chord = 2x = 2 × 12 = 24 cm
60/360 x 90 = 15
the answer is B
