6 minutes/60minutes = 0.1 hrs
45miles/0.1hour = 450 miles per hour or mph
1992.1875
1500/64000= 0.0234375
0.0234375 x 85000=1992.1875
Factorial is used to find the number of ways a given number of objects can be ordered
Answer:
c. 9 det A
Step-by-step explanation:
Given the following data;
Since A is a square matrix of order 2, we know that n = 2
K = 3
For any scalar k;
∣kA∣ = k^{n} ∣A∣
<em>Substituting into the equation;</em>
∣-3A∣ = -3²∣A∣
Simplifying, we have;
∣-3A∣ = 9∣A∣
= 9 detA
<em>Therefore, det (-3A) = 9 detA</em>
