4 miles every 6 minutes
So proportional relationship is 4:6
Simplified its 2:4
Given that the circle radius of 6 cm and a minor arc ST = 11pi/2. the measure of the angle rst can be solve using the formula s = ra
where s is the lenght of the minor arc
r is the radius of the circle
and a is the measure of the angle in radians
s = ra
a = s/r
a = (11pi/2) / 6
a = 11pi/12
or
a = 165 degrees is the measure of angle RST
Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
I don’t understand what the is question
The determinant of given matrix is zero
Step-by-step explanation:
Given matrix is:
![\left[\begin{array}{ccc}1&4&4\\5&2&2\\1&5&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%264%264%5C%5C5%262%262%5C%5C1%265%265%5Cend%7Barray%7D%5Cright%5D)
The determinant of a 3x3 matrix is calculated by selecting a single row.
We are choosing the first row.
So,
The determinant of given matrix is zero
