1. Brie knows there is a relationship between the grades on
her math tests and the time she spends studying for those
tests. Identify the independent quantity and the dependent
quantity in this problem situation.
Time is the independent variable as it can be treated as a controllable constant against which changes in a system can be measured. How much time you spend effects how much time you study, making studying the dependent.
Question 1. √80/6 Question 2. (2√5)^2
Answer:
Q1: is 0
Q2: is 20
Step-by-step explanation:
Q1: Divide the numbers 0 ÷ 6 = 0
√8 × 0
√8 = 2√2
2 × 0 × √2
Apply rule 0 × a = 0
Q2: Apply exponent rule : (a × b)^n = a^n b^n
2^2(√5)^2 = 2^2 (√5)^2
2^2 = 4
4 (√5)2
(√5)^2 = 5
4 × 5
Multiply the numbers: 4 × 5 = 20
True or False? (-x)^6 = -x^5 Explain your
answer (use either words or an example).
Answer:
False
Step-by-step explanation:
[tex](-x)^{6}[/tex] = [tex]x^{6}[/tex]
- [tex]x^{5}[/tex] = - [tex]x^{5}[/tex]
Thus
[tex](-x)^{6}[/tex] ≠ - [tex]x^{5}[/tex]
