Answer: answer is 19.2
a squared + b squared = c2
81 + 289 = 370
square root of 370 = 19.235
answer is 19.2
9514 1404 393
Answer:
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a^0 = 1 . . . . for a ≠ 0

And, it is convenient to know the cubes of small integers:
1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125
6³ = 216; 7³ = 343; 8³ = 512; 9³ = 729; 10³ = 1000
__
1) p^3 × p^5 = p^-12 × p^y
Equating exponents:
3 + 5 = -12 + y
20 = y . . . . . . . . . . . add 12
__
2) 64 × 4^5 = 4^3 × 4^5 = 4^(3+5) = 4^8

3) 10^x = 1 = 10^0
x = 0
We have to know the formula to finding the area of a circle. Since the area is clearly rounded, we can use 3.14 for pi.
R^2•3.14=78.5
Let’s divide both sides by 3.14.
R^2=25
5•5
5
So the radius is 5. The diameter is double the radius. The diameter of the circle is 10.
Answer:
i cold not find the answer
Step-by-step explanation:
True
-1, -2, -4, -8, ... is the non-arithmetic sequence. It’s geometric as there’s a common ratio of 2.
