Answer:
Okay, so a bit of math is involved, along with steps.
Step-by-step explanation:
Kyra invested $400 at 3% for 3 years. meaning 3% of $400 is 12. 400+12=
Year 1: $412
3% of 412=12.23+412=
Year 2: $424.23
3% of 424.23=12.7+423.23=
Year 3: $435.93
Kyra made $35.93 in investments.
Lishsawn invested $500 at 4% for 2 years. Meaning, 4% of $500 is 20. 500+20
Year 1: $520
4% of 520=20.8+520
Year 2: $540.8
Lishawn made $40.8 dollars in investments. Meaning that Lishawn made $4.87 more dollars
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>
20,000 • 26 = 520,000 miles.
In scientific notation, 520,000 becomes
5.20 x 10^5
