Answer:
RULES:
Half of your diameter is ALWAYS your radius.
15 divided by 2 = 7.5 cm
6.5 divided by 2 = 3.25 in.
3 divided by 2 = 1.5 ft
8 divided by 2 = 4 m
Answer:
The answer is the last one (32x^7y^15)
You can bring x to the second power (x^2) because (x) is basically x^1. This is a basic exponent rule. (x^m)^n = x^m times n.
Then you can apply this rule to (2xy^3)^5. First you bring two to the fifth power and get 32. Then you bring x^5 according to the rule. Then you bring y^15, also because of the rule.
Now you have:
x^2 times 32x^5y^15
Now you just multiply the like terms together (x^2 and x^5)
When you multiply two exponents with the same base, you add the exponents together: a^n times a^m = a^n+m.
So you end up with 32x^7y^15
Which one do you need help on
20,27,34
The common difference is 7
Decrease in the temperature: 5.4×5=27°C
Final temperature: 12-27=-15°C
